Stormborn

"Stormborn" is the second episode of the seventh season of Game of Thrones. It is the sixty-second episode of the series overall. It premiered on July 23, 2017. It was written by Bryan Cogman and directed by Mark Mylod.

Plot
Daenerys receives an unexpected visitor. Jon faces a revolt. Sam risks his career and life. Tyrion plans the conquest of Westeros.

At Dragonstone
During a thunderstorm at Dragonstone, Tyrion Lannister, Varys, and Queen Daenerys Targaryen talk about the stormy circumstances of her birth. Varys briefs her that Queen Cersei Lannister's position on Westeros is tenuous. Tyrion counsels her not to burn the Seven Kingdoms and proposes that she forges alliances with the other houses not currently aligned with Cersei. Dany then questions Varys about his previous services to her father the Mad King and King Robert Baratheon. Varys confides that King Robert had little interest in ruling, although at first, he appeared to be definite improvement over Aerys II.

Dany then confronts Varys about his role in hiring the assassins to target her. Dany distrusts him due to his track record of switching allegiances. Refusing to be intimidated, Varys points out that incompetent rulers do not deserve blind loyalty, then recounts his lowly origins as a castrated slave and tells her that his true loyalty lies with the oppressed masses. Varys tells Daenerys that if all she wants from him is blind loyalty, she may as well have him killed, but he is much more useful to her and to the Realm alive, and that he believes she is the last hope for the people. Dany accepts his fealty on the condition that he does not conspire against her – rather, she makes him swear to look here in the eye and tell her when she is wrong, as he is doing at this very moment. Seemingly pleased, Varys does so. Seemingly satisfied, Daenerys also warns Varys that if he betrays her, she will burn him alive. Varys replies that he would expect nothing less from the "Mother of Dragons."

Daenerys is then visited by the Red Priestess Melisandre, who believes that Dany might be The Prince That Was Promised. Varys questions Melisandre about her previous service to the ill-fated King Stannis Baratheon. While Daenerys initially does not believe that she could be the Prince, Missandei reassures her that the High Valyrian word for "prince" or "princess" is gender neutral. Melisandre tells Daenerys of Jon Snow, the King in the North, who has united the North and the Wildlings. Tyrion vouches for Jon Snow and convinces Daenerys that he will make a good ally. Dany accepts Tyrion's advice, and tells him to extend an invitation for Jon to attend her at Dragonstone – where Jon must "bend the knee."

In the Chamber of the Painted Table, Yara Greyjoy and Ellaria Sand firmly advocate an immediate assault on King's Landing. Tyrion advises against laying waste to the Kingdoms' capital and causing the deaths of tens of thousands of innocents. When Ellaria belittles him for his lack of stomach for war (despite his previous command and service at the Battle of the Blackwater), Tyrion openly accuses her of poisoning his niece Myrcella Baratheon; Ellaria does not deny it, and expresses regret that her lover Oberyn Martell died for the cause of Tyrion's freedom. Daenerys ends the argument with a rebuke for Ellaria to respect her Hand. Back to the matter of the invasion, Daenerys insists she doesn't wish to be known as the Queen of the Ashes, to which Olenna Tyrell sarcastically ponders if Daenerys will take the Iron Throne by asking politely, and reminds her of the fate of her granddaughter, Queen Margaery Tyrell, who was killed when Cersei blew up the Great Sept of Baelor. Tyrion proposes using a combination of Tyrell and Dornish forces to lay siege to King's Landing, much to the chagrin of Olenna and Ellaria, who balk at the thought of using their own soldiers. Tyrion, however, insists that using the Unsullied and Dothraki would arouse the patriotism of Westerosi bannermen, who would see them as foreign invaders and potentially close ranks behind Cersei. He proposes sending Grey Worm and the Unsullied to take Casterly Rock instead, cutting off Cersei's retreat and dealing a massive blow to the morale of the Western army. The Greyjoy fleet, meanwhile, will escort Ellaria back to Sunspear to rally the Dornish forces and then ferry them up the coast to King's Landing, bypassing the Stormlands and allowing the siege to commence early. Daenerys accepts Tyrion's proposal and reminds the others on her council that she will not be attacking King's Landing, and requests consenting approval from everyone, which they give. Daenerys dismisses everyone except Lady Olenna. The Dragon Queen tells the Queen of Thorns she is aware that her motives are based on revenge and not out of love for her. She insists that she will usher in an era of peace. Olenna, however, reflects that there was never a lasting peace under the Mad King, or any preceding Targaryen, for that matter. She tells Daenerys that Tyrion is a clever man, and that Olenna has outlasted many clever men by not listening to their advice. She tells Daenerys that the lords of Westeros are sheep, yet Daenerys is a dragon, and she must be one if she is to rule Westeros.

Later, Missandei visits Grey Worm to bid him farewell before his departure to Casterly Rock. Grey Worm confides that Missandei is his weakness, and when she expresses confusion, he tells her that the Good Masters of Astapor tortured the Unsullied by exposing them to their worst fears (i.e., if the young boy were afraid of drowning, he'd be thrown into the sea and if he drown it would be "good" and if he survived it would be "good" because only the fit survive). Grey Worm recalls that he was never the biggest/fastest/strongest but he was the most fearless warrior, until he met Missandei. She replies that she also has to deal with fear and kisses him. Missandei strips naked and proceeds to undress Grey Worm. Grey Worm is reluctant to remove his trousers (presumably not wanting to horrify her with his castration scars) but eventually acquiesces to Missandei's wishes. The two of them then share an intimate sexual encounter.

In King's Landing
In the throne room of the Red Keep, Queen Cersei Lannister gives a speech urging several nobles from the Reach, including Lord Randyll Tarly, to reaffirm their allegiance to the Iron Throne. Cersei warns that Daenerys' Dothraki hordes would pillage their lands and homes, and rape their women. When Lord Tarly points out that Daenerys has three dragons, Maester Qyburn replies that he is "working on the situation."

Following the audience with Queen Cersei, Lord Tarly meets in private with Jaime Lannister, who confides that he knows not to cross Cersei despite despising her. Jaime wants to appoint him as his general but Tarly is unwilling to break his fealty to Lady Olenna Tyrell. Randyll is wary of the Lannisters. Jaime admits that he dislikes his sister but convinces Tarly that Cersei is the lesser evil against Daenerys and her Dothraki. Jaime also offers the consolation that if they succeed, once Olenna is gone Cersei will make Randyll the new Warden of the South.

Later, Qyburn leads Cersei to the skulls of the dragon beneath the Red Keep. He tells Cersei that his spies have reported that one of Daenerys' dragons was wounded by a spear at Meereen, showing that the dragons are not invincible. Qyburn then displays a ballista and reassures her that they can hurt dragons. Cersei tests the ballista on the nearby skull of Balerion the Black Dread (the dragon of Aegon the Conqueror) and is pleased when the bolt pierces through the massive, hard skull.

In the North
At Winterfell, Jon Snow, Sansa Stark, and Davos Seaworth discuss Tyrion's letter that they have received. While Sansa suspects it might be a trap, Jon doesn't think so due to Tyrion ending the letter with the line "all dwarfs are bastards in their fathers' eyes", which Tyrion has told Jon in their first meeting years ago. Even so, Jon agrees that now is not the right time to go to Dragonstone. Davos opines that Dany will make a good ally in the war to come against the White Walkers.

Some days later, Maester Wolkan brings Jon Snow a message from Samwell Tarly in the Citadel. Jon gathers the Northern lords in the main hall and announces that Sam's letter reveals there is a vein of dragon glass beneath Dragonstone. He adds that Lord Tyrion has invited him to Dragonstone to meet with Queen Daenerys and announces his decision to travel to Dragonstone to convince Daenerys to join their fight against the White Walkers, declaring that he plans to travel with Davos to White Harbor and sail to Dragonstone island. Lords Yohn Royce and Robett Glover voice their opinions that a Targaryen cannot be trusted. Lady Lyanna Mormont urges the King in the North to stay at home. Jon accepts that he is taking a risk but stresses that the fight against the White Walkers is more important, and they need Daenerys' aid if the North is to be saved. Jon emphasizes that the North is his home, it is part of him, and he will never stop fighting for it. Sansa reiterates her objection to Jon's leaving, and Jon tells Sansa that he is appointing her as ruler of the North in his absence as she is his sister, regent, and a Stark. Sansa accepts, and Brienne of Tarth looks up at Sansa, alarmed. In the catacombs beneath Winterfell, Petyr Baelish meets with Jon Snow and vouches that Tyrion can be trusted. Petyr confides that he loved Jon's step-mother Catelyn Stark. When Jon says that Petyr does not belong down there, Baelish replies that Jon should be grateful to him for saving him. When Baelish tells Jon about his love for Sansa, Jon grabs him by the throat and warns him that he will kill him if he approaches his sister again. Jon, Davos, and several horsemen then prepare to ride south to White Harbor while Sansa watches from the castle battlements. Before he leaves, Jon looks at Sansa and they share a farewell moment. Petyr, emerging from the catacombs, gazes lustfully at Sansa.

In the Riverlands
Arya Stark encounters Hot Pie at the Inn at the Crossroads, accosting him to give her some pie and ale. Hot Pie tells her that he has become a seasoned pie-master, and Arya mentions that she has had some experience baking two pies (omitting the fact that she served Lothar Frey and Walder Rivers to their father, the late Lord Walder Frey). When Hot Pie asks Arya if the lady knight Brienne of Tarth had found her, Arya gives an affirmative answer. When Hot Pie asks where she is traveling to, Arya replies that she is traveling to King's Landing for the Queen. Hot Pie tells her that Queen Cersei has blown up the Great Sept of Baelor and wonders why she is not heading to Winterfell. Arya replies that the Boltons occupy the castle, but Hot Pie informs her that the Boltons are now dead, killed during the Battle of the Bastards by her half-brother Jon Snow, who has been named King in the North. Overcome with emotions she thought she'd never feel again, Arya decides to head north, and Hot Pie tells her not to worry about paying for the cost of the meal since she is friend. As she leaves, Hot Pie remarks that Arya is pretty for someone whom he thought was a boy. Arya rides her horse into a frost-covered forest.

Later, as Arya prepares to set up camp in a snowy, forested area, her horse is startled by several wolves. Before the wolves can attack her, they are silenced by their pack leader, which turns out to be Arya's direwolf Nymeria. Nymeria is initially apprehensive towards Arya, but soon recognizes her former mistress. Arya tells her direwolf that she is going home and invites her to come with her. However, Nymeria turns and leaves with the pack. Arya watches in sadness and remarks "That's not you."

In Oldtown
At the Citadel, Archmaester Ebrose and Samwell Tarly examine Jorah Mormont, whose greyscale has spread to his torso. The Archmaester tells Jorah that he should have cut off his lower arm instead of letting the infection spread. Ebrose states that Mormont is beyond saving. While it is customary for infected smallfolk to be sent to live with the stone men, Ebrose gives Mormont one more day, implying that the anointed knight could choose to commit suicide instead. When Sam asks about sending condolences to Jorah's family at House Mormont, Jorah replies that he is estranged from his family.Later, the Archmaester lectures Tarly about the art of writing history. Sam refuses to give up on Jorah and mentions that a previous Maester, Pylos, successfully treated two cases of advanced greyscale. Ebrose responds that Pylos contracted the disease himself and died of it. Undaunted, Sam decides to treat Jorah and visits his quarters. He tells Jorah, "You're not dying today" and reveals that he once served under Jorah's father, the late Lord Commander Jeor Mormont. Sam gives Jorah rum to drink, telling him that the process will be painful. Sam also provides Jorah with a mouthguard to muffle his screams. Sam's plan involves using a scalpel to scrape off Jorah's infected skin and then applying ointment. Despite the pain, Jorah consents to the treatment.

On the Narrow Sea
On the Narrow Sea, Princess Yara Greyjoy and her brother, Prince Theon Greyjoy, travel aboard their portion of the Iron Fleet with their Dornish allies Ellaria Sand, her daughter Tyene, and Tyene's half-sisters Obara and Nymeria Sand. In their quarters, the Sand Snakes argue about killing Lannisters while lying in bed. Elsewhere, Ellaria drinks Ironborn liquor with Yara and Theon, which she compares unfavorably to Dornish wine. Ellaria asks Yara if she had ever been to Dorne, to which Yara responds that she has been there a few times. Yara and Ellaria begin to sexually flirt with each other. Yara tells Ellaria that Theon will serve as both her bodyguard and adviser. While Yara and Ellaria began kissing, Yara's ship is struck. Up on the deck, they discover that their fleet has been ambushed by their uncle Euron Greyjoy's portion of the Iron Fleet.

Euron's ship extends a boarding ramp onto Yara's ship and lands a boarding party. Yara and her men fight fiercely but are overwhelmed by Euron's warriors. Tyene retreats to below the deck with her mother Ellaria, while Obara and Nymeria fight against Euron's Ironborn. Obara fights Euron, who kills her by impaling her with her own spear. Nymeria attacks him with her whip but Euron strangles her to death with it. Though Tyene kills several Ironborn, she and Ellaria are overwhelmed. Ellaria tells the Ironborn to kill them quickly, but they are taken captive instead. Yara and Euron fight with axes as Yara's fleet burns in the night. Euron captures Yara and then goads "little Theon" to come save her. Theon is about to come to his sister's aid but panics when Euron's men begin torturing the wounded sailors, reminding him of the tortures he suffered and massacres that he witnessed at Ramsay Bolton's hands. To Yara's dismay, Theon jumps overboard while Euron laughs with glee. Theon clings to driftwood and sees Obara and Nymeria's corpses impaled on and hanged by the neck from the prow, respectively. Euron's fleet starts sailing towards King's Landing as Yara's fleet burns in the Narrow Sea, while Theon watches helplessly as the ship carrying his sister disappears into the night.

General

 * The title refers to Daenerys Targaryen, and how she received her personal sobriquet, "Daenerys Stormborn" (which she has used throughout the series). Right before the rebels arrived at King's Landing at the end of Robert's Rebellion, her pregnant mother was sent to safety on Dragonstone. Her mother went into labor soon afterward, during a massive storm that smashed to pieces what little was left of the Targaryen fleet anchored at Dragonstone, before dying in childbirth. Being born during this ill-omened storm, she earned the nickname "Daenerys Stormborn". The episode itself opens with Tyrion and Daenerys referring to this.
 * The original title of this episode was actually "The Mad King's Daughter", as Bryan Cogman revealed after it aired. His initial draft of the episode had someone refer to her as "the Mad King's Daughter" in every other storyline, but these lines were trimmed for time from the final version (i.e. Cersei calls her that in the final cut, but someone would have called her that too in the Winterfell storyline). The idea was to stress that no one in Westeros really knows Daenerys because she's been in exile her whole life, and her father was an infamous, literally insane tyrant, so many people would realistically be somewhat wary of her.
 * The Bran Stark and Sandor Clegane storylines do not appear in this episode. The storyline of Daenerys and her various allies shifts into focus, which only briefly began at the end of last episode.
 * The Title sequence updated for this episode to replace The Twins from the preceding episode with Pyke - even though there are no scenes set in the Iron Islands themselves, the Greyjoy characters are very prominent in it (sometimes the animations are chosen on a representative basis).
 * This is one of the few episodes to actually refer to the eastern continent across the Narrow Sea from Westeros by name as "Essos" - only four times in the past six seasons, making this the fifth time. It is called "Essos" by name in both Daenerys's scenes and by Cersei. Essos is a loose fantasy analogue of Eurasia, and indeed is so vast that characters usually refer to a more specific region, such as "the Free Cities" or "the Dothraki Sea". A character saying "I am going to Essos" is loosely similar to someone in real life saying "I am going to Eurasia" - which could refer to anything from Italy to China.
 * This episode has two characters named "Nymeria" in it: Arya's direwolf Nymeria (who returns), and the Sand Snake, Nymeria Sand (who is killed). The dialogue simply avoids referring to Nymeria Sand by name. Both characters were named after Nymeria, queen of the Rhoynar, the founder of unified Dorne who lived a thousand years ago (Nymeria Sand is in fact her descendant as a member of House Martell) prior to this episode.
 * There are many references to events from past episodes:
 * Cersei brings up 5 twisted narratives of Daenerys's actions to win support. This is similiar to the tactics used during the Liberation of Slaver's Bay ("Breaker of Chains") where the slave masters used lies and scare tactics to terrify the slaves into submission.
 * The blind loyalty of Daenerys Targaryen's Unsullied, playing to the Westerosi opposition to Slavery, but leaving out that they are now free men loyal to her out of gratitude ("And Now His Watch Is Ended").
 * The Raiding culture of the Dothraki and Daenerys's speech to her Khalasar, ignoring that Daenerys herself seeks to change them ("Blood of My Blood"). Cersei ignores the fact that all of the Noble houses and Great Houses have committed similar atrocities during the War of the Five Kings. Jaime also uses this argument with Randyll Tarly.
 * Daenerys' crucifixtion of the 163 Great Masters, not revealing it was retaliation for their crucifixion of 163 children. The fact that the Great Masters were practitioners of slavery, an institution abhorred in Westeros, was also neglected ("Two Swords", "Oathkeeper").
 * Daenerys' execution of the Great Master she had burned alive and fed to Rhaegal and Viserion, not making it clear she was facing an insurgency ("Kill the Boy").
 * The legacy and actions of Aerys II Targaryen. Cersei focuses on the actions of the "Mad King" while ignoring Daenerys' history of avoiding his mistakes. Jon Snow is also reminded of Aerys II.
 * Jaime uses several of the same points, but moderates his arguments, he portrays Cersei as the lesser of two evils as House Lannister does not have a history of family madness and did not allow an army of slaves and Dothraki into Westeros.
 * Randyll Tarly implicitly mentions the destruction of the Great Sept of Baelor (how Cersei treats those who disobey her), the killing of Aerys (Oathbreaking and stabbing in the back) and the Red Wedding (Tywin Lannister and the Freys' violation of Guest right).
 * Jaime mentions Olenna's obession for revenge ("The Winds of Winter").
 * Yara's encounter with a courtesan ("The Broken Man").
 * Ramsay Bolton's treatment of Theon as a servant.
 * Ellaria's comment about Dornish red wines being the "best in the world" is a reference to the debate between the Dornish red and the Arbor gold.
 * Ebrose mentions Ch'Vyalthan, author of "An History of the Great Sieges of Westeros" ("The Prince of Winterfell") and Vaull ("The Watchers on the Wall").
 * Daenerys mentions that Illyrio falsely told her brother that the people of Westeros "drink secret toasts to his health" ("Winter Is Coming").
 * Daenerys refers to the failed attempt on her life in Vaes Dothrak ("You Win or You Die").
 * Varys admits he implemented Robert's plan to assassinate Daenerys ("The Wolf and the Lion") (though Tyrion later suspected that Varys intentionally had the plan fail, Varys does not confirm this).Письмо Тириона Джону Сноу 7x02.jpg
 * Tyrion uses the phrase "all dwarfs are bastards in their father's eyes" in his letter to Jon. Jon recalls that Tyrion told him that before when they first met ("Winter Is Coming").
 * Randyl Tarly refers to the battle of Ashford, which was mentioned by Stannis ("Kill the Boy").
 * Robett Glover re-states the political failings of Robb Stark ("The Broken Man").
 * Qyburn refers to young Drogon's injury in the fighting pits of Meereen ("The Dance of Dragons"). The ballista he shows Cersei is a reference to the death of Meraxes.
 * Euron's "gift" is the capture of the members of House Martell who were responsible for the Assassination of Myrcella Baratheon. His capture of Yara will be a "gift" to himself, as Yara's capture will destroy her claim to the Kingdom of the Iron Islands ("Dragonstone (episode)").
 * The merchants at the inn where Arya stays talk about the rise of food prices if King's Landing is placed under siege. This is a reference to the previous siege during the War of the Five Kings ("The Prince of Winterfell").
 * Tyrion speaks about the Assassination of Myrcella Baratheon ("Mother's Mercy").
 * Arya mentions that she made pies before ("The Winds of Winter"), without being specific about the ingredients (Frey pie).
 * Hot Pie tells Arya about meeting Brienne ("Mockingbird"), he against describes as a "lady knight" despite women not being allowed to be knights, part of the running gag that he keeps getting confused that anyone who wears armor must be a knight.
 * Arya tells Hot Pie that she met Brienne ("The Children").
 * Hot Pie brings Arya up to speed by informing her of the destruction of the Great Sept of Baelor ("The Winds of Winter") and Battle of the Bastards.
 * Jon grabs Littlefinger by the throat, and slams him against a wall, just like Ned did in "Lord Snow" (both for making somewhat creepy verbal advances about a female relative).

In the North

 * Jon Snow receives letters via messenger-raven from both Dragonstone and Oldtown in this episode, but no message from Castle Black at The Wall informing Winterfell that Bran Stark, last legitimate son of Ned Stark and rightful heir to the North, is still alive, even though that was shown in the preceding episode - but this is not inherently an error. The writers already stated in prior seasons that regarding the internal Timeline, the geographically separated storylines in each episode aren't strictly synchronized. We the audience saw Bran Stark reach the Wall at the beginning of the previous episode, but within the fictional universe, that apparently happened after Jon Snow left Winterfell. Nothing in Bran's brief introduction scene in the prior episode referred to events in other storylines, so this doesn't contradict anything.
 * In the previous episode, and in the Season 6 finale before that, it was unclear if Samwell was aware that Jon wasn't Lord Commander of the Night's Watch anymore, or heard rumor that he had died and been resurrected (more difficult to believe if he wasn't here). Apparently he was at least informed off-screen that Jon is King in the North now (it's common knowledge across Westeros at this point, even Hot Pie knew at the inn when Arya came), so he sent his letters directly to Winterfell - there's no indication that they were sent to Castle Black first.
 * The Order of Maesters doesn't have its own official Heraldry symbol. The books only mention that the "symbol" of a master is the chain of office that he wears around his neck (they don't carry banners). The prop letter that Jon receives from Samwell in this episode, however, sent from the Citadel, needed to be stamped with some kind of wax seal - so its seal uses the symbol of a maester's chain, artistically depicted as a circular chain ring with twelve links in it.
 * Jon Snow receives a letter from Samwell Tarly in Oldtown about how there is literally a mountain of dragonglass underneath volcanic Dragonstone island - raising the question of why Davos Seaworth never told Jon about this in the first place. In the preceding episode, Sam even acknowledged that Stannis Baratheon told him there was dragonglass there (back in Season 5). It actually isn't impossible to reconcile all of this: as presented, it seems that Stannis and Davos were aware that loose dragonglass can be found scattered throughout the island, but this specific dragonglass mine deep under the volcano was abandoned and forgotten generations ago. The clearly visible book page Sam was reading, with the map of Dragonstone on it, makes this more explicit: it says that even the Valyrian Freehold, with its continent-spanning empire, judged this to be the largest concentration of dragonglass in the known world - that's why they created a colony there to begin with. Thus, it seems that this ancient Valyrian dragonglass mine was long abandoned, so even Stannis didn't know just how much dragonglass was truly there.
 * In the fifth novel, Tyrion muses at one point on why the Valyrians only colonized Dragonstone, and didn't try to conquer the rest of Westeros. At the time it was divided into seven divided and constantly feuding kingdoms, which could not have withstood their many dragons and vast armies (Aegon I Targaryen later managed to conquer all of it with only a fraction of their strength). The commonly held view of historians is that they founded it as a trading outpost - but there were plenty of other islands they could have occupied. All of the wealth in Westeros was farther west, in the gold mines of the Westerlands or the rich fields of the Reach - they knew it was there, but chose just to focus on Dragonstone. This may have been setting up that the Valyrians – the only people besides the Children of the Forest to extensively use dragonglass – actually settled Dragonstone specifically to control its vast dragonglass deposits.
 * Jon Snow says during the council scene that "we know Dragonglass can destroy both White Walkers and their army" - referring to their hordes of undead Wights. Staff writer Dave Hill gave an interview a few days before this episode aired in which he stated that was indeed an official change in the TV continuity: in the books, dragonglass only kills White Walkers. Wights can only effectively be destroyed by fire - they keep fighting until they are hacked to pieces, and even then, the individual parts will still move as long as they have some range of motion left (such as a severed hand crawling towards a person). Hill didn't give a reason why this change was made - possibly because it would be too difficult to work with large numbers of stuntmen actually being set on fire (while wearing protective layers); changing it so that dragonglass works on wights as well allows for more manageable fight choreography. Hill said that this change was introduced during the Battle at the Cave of the Three-eyed Raven in Season 6's "The Door" (apparently it wasn't clearly visible due to how chaotic the fight sequence was).
 * In the books, Sam discovers by trial-and-error that dragonglass is ineffective against wights: on the way to Castle Black, a wight attacks him and Gilly (in the show it was replaced with an Other). Sam stabs the wight with a dragonsglass dagger, but it shatters to pieces. Sam stabs the wight with his steel dagger, but it just bounces off the wight's iron mail (it would hardly matter even if the wight was not armored - at best Sam could cut a limb of it, and it wouldn't stop the wight). Desperately, Sam grabs a burning piece of wood and shoves it into the wight's mouth, immediately causing the whole creature to burst into flame and be destroyed. Later, Sam tells Melisandre about the anomaly, that what kills Others (White Walkers) is ineffective against wights. She explained "Necromancy animates these wights, yet they are still only dead flesh. Steel and fire will serve for them. The ones you call the Others are something more".
 * Jon's direwolf Ghost does not appear in this episode. Episode writer Bryan Cogman explained via Twitter that a scene between Ghost and Jon was not only scripted but filmed, yet it was cut from the final version of the episode.
 * The Winterfell scenes open with children being trained to fire bows and arrows in the courtyard, both boys and girls - following from the preceding episode when Jon said that they needed everyone physically capable of lifting a weapon train to fight the White Walkers, so he commanded that everyone from age 10 to 60, male or female, start getting basic training.
 * This shot somewhat parallels the first scene at Winterfell in the first episode of the TV series when the Starks were introduced: the male and female heads of House Stark (Ned and Catelyn then, Jon and Sansa now) overlooking boys and girls using bows and arrows in the courtyard (Bran was training in the premiere, then Arya shot one from behind him), when they are interrupted by a messenger who says that a raven has arrived with a message from the south.
 * Aerys Rickard Brandon.png asks Jon to remember what happened to "our grandfather", [[Rickard Stark]], who summoned to King's Landing by Daenerys's own father, the Mad King, who then roasted him alive. Ned's father Rickard was seen on-screen during Bran's visions in Season 6. Despite Jon secretly not being Ned's son, Sansa's statement is nonetheless technically correct: Jon is the son of Ned's sister Lyanna, so either way, Rickard was still his biological grandfather, albeit through his mother rather than through his father (on that side, Jon's grandfather is actually the Mad King, meaning that one of his grandfathers was responsible for the death of the other).
 * This council scene is the first time that Sansa Stark is shown as being a "political player" (in the "game of thrones"): making political arguments and decisions that affect large scale strategies (prior to this she just went along with whatever Littlefinger manipulated her into doing). In the preceding episode she argued with Jon about pardoning the children of lords who served the Boltons, and she got a few shouts of support, but was ultimately overruled by Jon. In this episode, Sansa makes a fact-based argument that Jon makes no attempt to deny (Daenerys's father did kill their grandfather), and Lord Yohn Royce outright stands up and says, "I agree with Lady Sansa". Jon doesn't manage to sway any of the other lords to his decision, he simply says he never asked to be king and will go anyway, so if he dies and Sansa is proven right she will rule the North after him. Leaving Sansa as acting ruler of Winterfell is also the first time she's officially been in command of anything politically.
 * It is unclear why, if Sansa has grown to distrust Littlefinger, she doesn't simply tell the Vale lords that he actually murdered her aunt Lysa Arryn. It's possible she fears that Littlefinger still has more control over her cousin Sweetrobin Arryn, and there are no other witnesses, so it might risk her alliance with the Vale lords - for now.
 * Lord Yohn Royce says that he remembers the Mad King. Not only did the Vale fight against the Targaryens in Robert's Rebellion, in the books Lord Royce was actually present at the Tourney of Harrenhal, the first time that King Aerys showed himself in public in many years - and everyone in attendance was stunned to see how visibly insane the king had become, randomly switching from rage to laughter to crying without provocation, reacting to hallucinations that weren't there, and with a deranged appearance (ropes of matted hair and inches-long fingernails). Thus Lord Royce can say with validity that he remembers the Mad King, from personal observation, not just that he heard second-hand news about his atrocities or fought Targaryen forces in the war.
 * Lord Robett Glover again voices his accurate criticisms of Robb Stark that he originally made when he first appeared in Season 6's "The Broken Man": Robb went south with his army, but he made bad decisions that ultimately cost him the war and got all of his men killed along with himself at the Red Wedding. In the books, other characters more frequently criticize that Robb was brave and a great military leader, but as a young and inexperienced boy-king made political mistakes that led the North to defeat.
 * Alys Karstark and Ned Umber are visible in the background of the Winterfell council scenes, but have no speaking lines.
 * In the exterior sets of Winterfell, the various stone direwolf engravings and statuettes have been restored. When the Boltons took over, the production team made it a point to show that all of them had been smashed or defaced, off-screen. Since the Starks took back control, they apparently set about restoring those as well.
 * In the crypts, a statue of Eddard Stark has been erected in his memory, as is traditional for every Stark buried there. Petyr Baelish mentions that he delivered Eddard's remains himself as a gesture of goodwill from Tyrion Lannister, which occurred in Season 2's "Garden of Bones". The dialogue might not be explicit: he delivered Ned's remains to Catelyn, while she was in Renly Baratheon's camp, and she sent some of her men back north with them while she stayed there.
 * In the current books, it is still unconfirmed if Ned's remains ever actually reached Winterfell, as it wasn't mentioned again (and they would have to be transported through the main front in the war in the Riverlands). Season 6's "Battle of the Bastards" already established this, by having Jon state that Ned's remains are buried in the Winterfell crypts now.
 * Jon's harshness towards Littlefinger is left unexplained; he hasn't had scenes with him before, and it currently unknown whether or not he knows the role Littlefinger played in Eddard Stark's arrest (which subsequently resulted in his death, though Littlefinger had no direct part in Eddard's death). It's possible that Sansa told him more off-screen, but even Sansa isn't in much position to know the full extent of Littlefinger's treachery - she knows that he continued to serve the Lannisters, but only to later betray them by killing Joffrey. Littlefinger makes it clear that he loves Sansa, but adds "as I loved her mother", likely giving Jon the (quite truthful) impression that he harbors (unrequited) lustful feelings towards Sansa, and prompting him to threaten Littlefinger with death if he touches Sansa. Another explanation is that Jon simply became irritated at Littlefinger for reminding him of Catelyn Stark's coldness towards him, and his motherless childhood, although Baelish's implicated intentions towards the only family Jon knows he has left are certainly enough to send him into a rage. As seen in Season 2's "Garden of Bones", Littlefinger can get a little too enthusiastic about his desire for Catelyn/Sansa when talking about it, letting his act slip enough that his stalker-crush becomes apparent to other people.
 * Jon's decision to go to Dragonstone himself is questionable: a monarch would normally send an envoy, as Sansa suggested; if the monarch goes himself, it may give the impression that he is lesser than the monarch who invited him. Morever, Jon should have considered that perhaps Daenerys hates his house for supporting Robert against her father. Indeed in the books she feels that way, and has not changed her mind yet.
 * In contrast to the show ("The House of Black and White"), Ser Barristan Selmy tells Daenerys a very "sugarcoated" version about her father, implying very gently that he was insane, omitting all the atrocities he committed; the worst thing Daenerys hears about her father is that he lusted after Joanna Lannister and acted indecently at her bedding. Neither Selmy nor anyone else ever told Daenerys the whole ugly truth about her father.
 * A likely explanation is that Jon, being the only person in the North who has actually seen the Night King and his army (as shown in Season 5's "Hardhome"), believes himself to be the best person to explain the situation to Daenerys as opposed to an envoy who has not seen the Night King. A few other people have seen the Night King, Tormund's wildlings, Dolorous Edd and a few Night's Watch members, but they've been sent away already, and even if Jon could send them, he would risk insulting Daenerys by sending such an envoy when she asked for him in person. Jon is afraid enough of the Night King that he's willing to risk anything to convince Daenerys to ally with him.

In the Riverlands

 * Hot Pie returns in this episode, after being absent since Season 4's "Mockingbird", in which he met Brienne of Tarth and Podrick Payne and told them what he knew about Arya Stark. In this episode, Hot Pie asks Arya if Brienne found her; she confirms it, but does not divulge why she did not go with her, as seen in Season 4's "The Children".
 * Hot Pie was part of the batch of Night's Watch recruits that Yoren smuggled Arya out of King's Landing with in the Season 1 finale. After escaping Harrenhal with Arya and Gendry in Season 2, then running into the Brotherhood Without Banners, he parted ways with Arya in Season 3, when he found the relative safety of the Inn at the Crossroads, where the owner gave him a job as a cook due to his skill at it (as he was a baker's apprentice). Not being martially skilled, he felt Arya's dangerous journey wasn't really for him. Though he stayed behind, they wished each other well.
 * Hot Pie refers to the fact that Arya disguised herself as a boy while she was with the Night's Watch recruits (on Yoren's instruction), as the Watch doesn't take female members. Arya was around 11 going on 12 years old then so she was able to pass for a boy - Hot Pie is a bit hard on himself by saying Arya's too pretty to be mistaken for a boy now, as roughly five or six years of internal story time have passed since then (Arya is around 17 years old at this point).
 * This is the first time in the show that someone tells Arya she is pretty. In the books, Arya was never considered pretty, in contrast to her sister. She has always been a tomboy, and never cared how she looked; as a result, she earned derogatory nicknames like "Arya Underfoot" and "Arya Horseface". However, as the novel's go on, characters begin to state that Arya is becoming pretty. This is similar to Lyanna. Eddard even said that Arya looked like Lyanna at her age, and grew up to be very beautiful.
 * Similarly, Hot Pie still refers to Arya as "Arry", the boy's name she adopted as part of her disguise. It is the name that Hot Pie knew her by for a long time, though by the time they parted in Season 3 he knew that she was really Arya Stark. Of course, Hot Pie also has a ongoing habit of mixing up names, so continuing to call her "Arry" out of habit fits his character.
 * Arya says goodbye by saying, "Take care of yourself Hot Pie. Try not to get killed" - even though he is in the relatively safe position of working as a baker at an inn (albeit the ongoing war is ravaging the countryside). Hot Pie confidently responds that he's like her, he's a survivor - apparently this exchange is an in-joke at how Hot Pie has managed to survive all the way from Season 1 to Season 7 - despite not even being a Starring Cast member or important lord, but just a random commoner. Of 19 human characters introduced in Season 1 who are still alive, only three were never promoted to "Starring Cast" on the show: Sweetrobin Aryn, Ilyn Payne, and Hot Pie. Not being as socially important as the other two (who are nobles), there was never any guarantee that Hot Pie would survive from one episode to the next (even less than the Starring cast on Game of Thrones). Despite this, Hot Pie has somehow managed to avoid being killed for the entire run of the TV series up to now, often due to blind luck, i.e. in Season 2 when he realized that Gregor Clegane was picking prisoners to execute purely at random, but didn't get picked.
 * Arya, of course, refers to the "Frey pie" she made for Walder Frey in the Season 6 finale, made of his own sons.
 * This episode seems to indicate that it is now widespread and accepted knowledge throughout Westeros that Cersei was responsible for blowing up the Great Sept, an act of sacrilege killing hundreds of people - given that even Hot Pie, a common baker at a major inn, is aware of it.
 * Hot Pie indicates that the "Battle of the Bastards" is known by that name in-universe, referring to it as such.
 * Arya immediately starts sloppily digging in to the pie she was given, eating with no table manners - possibly a hint at the influence of traveling with the gruff Sandor Clegane for so long.
 * In behind the scenes videos from prior seasons, the showrunners said that Arya was losing herself in violence and revenge, but several major critics assessed that Arya's mental state wasn't visibly affected despite the number of people she killed. In this episode, however, much of this consequence is shown: Arya's reunion scene with Hot Pie depicts her as numb and emotionally dissociated, still somewhat detached after just killing several dozen Freys (even though she felt they deserved it). Hot Pie still behaves the way he did in the middle of Season 3, but Arya has been through a lot more since then (i.e. coming to the outskirts of the Red Wedding, hearing that her mother and brother were dead and the North lost). Apparently her mind is focused at this point purely on killing Cersei, with no thought to the future. Only Hot Pie's news that the North has risen again under her own brother Jon Snow starts to snap her back to being more like old "Arya".
 * Arya was apparently so focused on killing the Freys, then Cersei, that she never stopped to ask about news of events in the rest of Westeros, that Jon retook the North. Given the large distance between The Twins and the Inn at the Crossroads, however, and their storylines aren't in synch, it's possible that she killed the Freys then left around the same time the Battle of the Bastards took place, and she was alone on the road after that. The Lannister soldiers she ran into last episode weren't in a position to tell her about it either, because they were out in the field (they pointed out that they were common soldiers and didn't have messenger-ravens, and weren't in communication with their home castles).
 * The merchants in the background of the inn remark that if Daenerys besieges King's Landing, food prices will triple, provided that they get to the city before the siege starts and everyone starves. The same thing happened at the beginning of the War of the Five Kings, with food shortages leading to the food riots in Season 2. With the Tyrells were supporting Renly, the Starks and Lannisters fighting over the Riverlands, and Stannis blockading sea shipments, King's Landing was cut off from its major food suppliers, reduced to just a trickle from the immediate lordships of the Crownlands. The books went into this in some more detail, with Tyrion explicitly noting that drastic hyperinflation was setting in at the food markets - one Gold Dragon coin, which before the war was worth a knight's horse (the medieval equivalent of a nice automobile), could now only buy six skinny piglets or a side of beef; in the first novel a baker in King's Landing told Arya that a loaf of bread coast 3 Copper Pennies, but when Tyrion visits the same market in the second novel, 6 Copper Pennies can only buy one melon. See the main article on "Currency" for more price information.
 * When discussing Stannis Baratheon and his planned assault on King's Landing in Season 2's "The Prince of Winterfell", Bronn tells Tyrion Lannister and Varys that sieges kill more people from starvation than combat. The lords and ladys sell their diamonds for a "sack of potatoes" and the Smallfolk will become cannibals if the situation becomes desperate. This allows the thieves to become the "richest men in town" by stealing the food and re-selling it.
 * The merchants also remark as they leave the inn that the distance from there to King's Landing is 200 miles. The novels haven't given the exact distance - though the merchants might have just been mistaken.
 * Arya Stark's direwolf Nymeria finally returns after being absent since Season 1's "The Kingsroad". Arya previously ordered Nymeria to flee for her life after she attacked Joffrey Baratheon to defend Arya, in Season 1 episode 2 "The Kingsroad" (making this an absence of exactly 60 episodes). This led to the vindictive Cersei having Sansa's direwolf Lady executed in her place. In the intervening six years, Nymeria grew into a formidable adult direwolf the size of a small horse, and is leading her own pack of common wolves in the Riverlands. Arya also originally had Nymeria flee right before they reached the Inn at the Crossroads, while heading south - in this episode, Arya encounters Nymeria again just north of the Inn, on her way back.
 * There are more hints in the novels about Nymeria's survival and activities in the intervening books, which are peppered with sporadic reports that an unusually large wolf is leading a growing wolf pack in the Riverlands, feasting on the slain after battles and harassing farmsteads. Common wolves fear men and will avoid them whenever possible, but the huge Nymeria has no fear of man and leads her pack on bold attacks for food - catching their targets unprepared, who are used to just having to scare off wolves instead of fighting them outright.
 * Arya's interaction with Nymeria shows displays more signs of her journey back to being "Arya Stark". In both the books and novels, a running theme with Arya is her loss of identity: how she keeps adopting new fake names to hide her identity (i.e. Arry the refugee boy, among more in the books) until she is adopting fake personas in her Faceless Men training, ultimately trying to be "no one" like them. Arya can't give up her Stark past, however, she keeps her sword Needle and decides to come home. Arya is still slowly pulling back from her adopted personas and remembering herself before the war began: in this episode, Hot Pie calls her "Arry" multiple times throughout their scene but she doesn't correct him. Only when she sees Nymeria does she outright state her identity as "It's me, Arya".
 * In the Inside the Episode video, the showrunners directly explain why Nymeria didn't come with Arya, and what Arya meant when she said, "That's not you". It was a direct callback to the Season 1 scene in which her own father Ned said that she's grow up to be a proper lady and rule over a castle, but Arya said, "That's not me" - she wanted to keep being a tomboy and learning to use a sword. She wasn't denying it was Nymeria that she saw - as the showrunners state, what Arya meant was she realized and accepted that, like herself, a direwolf can't be tamed, Nymeria has her own life now with her wolf pack, and she can't expect her to give that up to come back with Arya.
 * Now that it is winter, a thin layer of snow is seen at the Crossroads Inn - the farthest south that it has been seen snowing in Westeros so far (in the preceding episode, it was seen snowing a little further north in the Riverlands, between the Twins and Fairmarket).

At Dragonstone

 * Daenerys Targaryen becomes aware of Jon Snow for the first time, unaware that he is her nephew by blood, being the son of her older brother, Rhaegar Targaryen, but believing him to be Eddard Stark's bastard son.
 * Tyrion Lannister recalls accompanying Jon Snow to the Wall in Season 1's "The Kingsroad", and cites the deaths of Eddard Stark and Robb Stark at the hands of the Lannisters as reasons why Jon will likely ally with Daenerys against Cersei, despite Aerys Targaryen's crimes against House Stark and House Stark's role in the subsequent rebellion against him. On the other hand, Daenerys wasn't even born when her father killed Jon's grandfather, while Cersei directly betrayed Ned and benefitted from Robb's defeat.
 * Olenna Tyrell meets Daenerys Targaryen in this episode. Interestingly, Olenna is one of the few characters left alive by this point who is old enough to remember when House Targaryen was originally in power and held the Iron Throne - even the time before the reign of the Mad King, when King Aegon V Targaryen was a good and stable monarch (Aegon V being Maester Aemon's younger brother). Other older characters who might remember those days – Aemon, Tywin Lannister or even Barristan Selmy – are dead by this point in the TV series. Olenna actually mentioned back in Season 4's "Oathkeeper" that in her youth she was originally betrothed to "some Targaryen or other" as it was "all the rage" due their then-stable rule. Of course, not personally wanting the match, she managed to get out of it and married Luthor Tyrell instead. In the books, Olenna was betrothed to one of King Aegon V's sons, but he actually wasn't attracted to her either because he was secretly a homosexual, and ultimately argued with his father as well to have the betrothal called off.
 * Bryan Cogman (who also wrote "Oathkeeper") explained in subsequent interviews that he likes putting in historical details like this to try to weave disparate story elements together (the Targaryen storyline in Essos isn't in utter isolation from the Westeros storylines, they used to rule Westeros); however, he said that while he actually did write more historical references for this episode, they were ultimately cut for time, because it was a lot of exposition that wasn't directly relevant to the current plot. In the finished version, Olenna only vaguely refers to the fact that she lived through the reigns of Daenerys's father, and his father before him - and there were just as many wars then as there are now.
 * The prophecy of The Prince That Was Promised is mentioned very prominently in Daenerys's conversation with Melisandre; it has been mentioned only sporadically in earlier TV seasons, but was much more prominently foreshadowed in the novels. The TV producers stated that they tried to avoid setting up prophecies when possible, because it ties them in to a future storyline that they don't have an absolute guarantee they'll be able to finish. The novels also explain that the High Valyrian word for "prince" used in the prophecy is gender-neutral - sort of like "Ruler That Was Promised" or "Leader That Was Promised" in English. The phrasing consistently used is "Prince That Was Promised", which Melisandre even used last season, though this episode renders it as "Prince Who Was Promised" - though as this is itself a translation from the original High Valyrian, it's probably up to the choice of the translator.
 * At first glance, it might seem odd that Daenerys is unaware that the High Valyrian word for "prince" is gender-neutral, given that she was just speaking with Melisandre in High Valyrian about the prophecy, and moreover, Daenerys even stressed in Season 3's "And Now His Watch Is Ended" that Valyrian is her mother tongue. Missandei, a skilled translator, even says that Daenerys's High Valyrian is excellent in Season 3's "Second Sons". The prophecy is set up much more in the novels, however, explaining that this is a mistaken assumption many people made, particularly in the past three generations since the Targaryens took an interest in it (around the time of Daenerys's grandfather). Daenerys's older brother Rhaegar was motivated by the prophecy; Rhaegar also frequently wrote correspondence with Maester Aemon (his grandfather's uncle) at the Wall. Both of them knew High Valyrian very well. Yet when Maester Aemon hears that Daenerys is not only alive but has hatched three new dragons, the possibility occurs to him that Daenerys is the prophesied figure, at which he laments that in all these years it simply never occurred to him that the "ruler who was promised" could also be a woman. This scene only occurs in the TV series, as Daenerys hasn't heard of the prophecy yet in the books - but if in the books it didn't even occur to a very well educated scholar and Targaryen like Maester Aemon for so long, it isn't unreasonable that it wouldn't occur to TV-Daenerys either after a brief mention. Aemon even says the prophecy was made a thousand years ago, and in all that time translators never stressed that it could be a man or a woman, rendering it as just "prince".
 * After the episode aired, staff linguist David J. Peterson indeed confirmed that this is how he would justify the scene, that Daenerys doesn't realize that "prince" is gender-neutral in High Valyrian - specifically citing that it simply didn't occur to Maester Aemon either in the books. Peterson said of the issue, "When I saw it in the script, I didn't even question it. Seems fine to me now." The example Peterson also used that even in English, it is common for occupation nouns to be non-gendered - "surgeon", "doctor", "actor" - but if you refer to a "surgeon" out of context, many native English speakers will still assume that the surgeon is a man.
 * The actual High Valyrian word - which can be translated as "prince" or "princess" - wasn't actually given in the novels. In the High Valyrian language that Peterson constructed for the TV series, the word is "dārilaros".
 * Reacting via Twitter, Sam Coleman (Young Hodor) compared it to how the word "doctor", such as in the TV series Doctor Who, can equally refer to a male or female Doctor.
 * In the books, Aemon goes on to explain that dragons themselves were a hint that a "prince" can be male or female - people forgot how dragon reproduction worked after they died out, but dragons can actually switch from female to male and back to female again, as mutable as flames - apparently this influenced High Valyrian to not use specific genders for terms regarding powerful figures. The TV show hasn't introduced this point about dragon biology.
 * Melisandre introduces herself to Daenerys by saying "I am called Melisandre" - called, not simply "My name is Melisandre". This may be a hint to the novels, in which it is revealed in Melisandre's few POV chapters in the fifth novel that this isn't her original name:  long ago, when she was a child, her original name was "Melony".  After that she was sold at a slave auction, at which she was just "Lot Seven".
 * Melisandre was previously seen speaking High Valyrian with Thoros in Season 3. High Valyrian was the language of the fallen Valyrian Freehold, their fantasy analogue of the Roman Republic, but High Valyrian remained the language of well-educated people in Essos, much like Latin in real-life medieval Europe (and many people in Westeros learn it as well).  The common everyday speech of the general populace diverged over time into Low Valyrian, much as Italian or Spanish diverged from Latin.  Thus the "Valyrian" that Grey Worm and Missandei were speaking in Season 3 is actually a variant of Low Valyrian, and not exactly the same language that Daenerys is speaking in now.  In the books, Melisandre is described as fluently speaking and saying prayers in three languages:  Asshai'i (the language of Asshai, where she says she is from), High Valyrian, and the Common Tongue of Westeros.
 * Daenerys welcomes Melisandre because the Red Priests helped to keep the peace in Meereen, back in Season 6. Tyrion actually met with Kinvara in Meereen, another high-ranking priestess from Volantis while Melisandre is from Asshai, put apparently they are both part of the same religious organization (the books haven't clearly explained the hierarchy of the Lord of Light religion]]).
 * Melisandre still believes that Jon Snow to be The Prince That Was Promised. Actress Carice van Houten stated in an interview with the LA Times that "She’s still on the path of Jon and just knows that they have to meet in order to ... God knows, but she’s on Jon’s track." Note that Melisandre only says Daenerys "has a role to play" and does not say that Daenerys is The Prince That Was Promised.
 * Another part of the prophecy given in the books is that "the dragon has three heads" - as hinted by the three-headed dragon used in House Targaryen's heraldry. That is, "the Prince" might not actually be one person but a group of three people acting towards a common goal.  Many also think it has to be someone of the Targaryen bloodline - Rhaegar was convinced of this, but it might not strictly be a requirement for all three persons, if true.
 * Melisandre's gives an added line of the prophecy in this episode which is not in the books, and might be a spoiler for future novels: "The Prince Who Was Promised will bring the dawn".  The first war against the White Walkers 8,000 years ago to end the Long Night was called the War for the Dawn, war to bring back the dawn, etc.
 * It is possible that this new line may in fact refer to the sword, "Dawn", forged from a falling star (and as strong as Valyrian steel. Part of the prophecy is that the Prince would be born under a falling star - then the TV series flashback last season made it a point to show that young Ned Stark rested the sword Dawn at the foot of his sister's bed right after she gave birth (so this part of the prophecy might be figurative).  In the books, Ned returned Dawn back to Starfall, the home castle of Arthur Dayne's family.
 * In the books, Daenerys initially hates the Starks, along with the Baratheons and Lannisters, for their role in the downfall of her family's dynasty - a she has to go on are her brother Viserys's skewed version of events. Only later in Meereen does Ser Barristan Selmy explain that her father really was an insane tyrant, and that Ned tried to dissuade Robert from sending assassins after her (Barristan was present at the Small Council scene in which was discussed in the books, but he was absent in the TV version - though others could have just told him about the assassination plan, similar to how Renly told Loras about it).  Daenerys is still upset when Barristan tells her this and it doesn't change her mind at the moment.  It remains to be seen how she would treat Ned Stark's children, who like her weren't even alive during Missandei and Grey Wormat she forgave Tyrion (who was just at the time) and was willing to work with him, not holding him responsible for the death of her king, she may act the same towards Jon.
 * Daenerys says she will not be "queen of the ashes". This is perhaps a reference to the novels: one of the visions Daenerys sees in the House of the Undying is of her father, telling someone (perhaps Rossart) "Let him [Robert] be king over charred bones and cooked meat. Let him be the king of ashes" - referring to the Wildfire Plot. The same turn of phrase was also used in the TV series in Season 3, when Varys said that Littlefinger doesn't care who he has to hurt to seize power:  he would burn Westeros to the ground so long as he got to call himself king of the ashes.
 * Tyrion Lannister clearly resents Ellaria Sand for killing his niece Myrcella Baratheon, which occurred in the Season 5 finale "Mother's Mercy", and claims that "we don't poison little girls here", which seems to be a reference to Oberyn Martell's promise to Cersei that Myrcella would be safe in Dorne ("We don't hurt little girls in Dorne"). Unlike the psychotic Joffrey, Tyrion had a good and loving relationship with Cersei's younger two children.  Though Tyrion is in a position to demand justice for Myrcella's murder, a likely reason he does not is out of fear that the Dornish will withdraw support if Daenerys kills Ellaria and the Sand Snakes.
 * It is unknown if the Dornish will kill Myrcella in future novels, as their storyline has been drastically changed, though in the most recent novels some of the Sand Snakes depart for King's Landing (where Myrcella recently returned) with the intent of stirring up trouble between the Lannisters and Tyrells.

In King's Landing

 * The intention of Qyburn to use a custom-made ballista against Daenerys's dragons appears to be a reference to how the dragon Meraxes died in the First Dornish War. While the Targaryens conquered the rest of the Seven Kingdoms in the War of Conquest, the harsh desert of Dorne proved quite an obstacle. A few years later they returned and captured all of its castles and towns, but the Dornish launched a brutal guerrilla war against their occupation forces. The Targaryens responded by burning any castle which rose against them with dragonfire, but the Dornish armies would flee when the dragons came and return as soon as they left. When Queen Rhaenys Targaryen attacked Hellholt while flying Meraxes, however, the garrison put up a stiff defense, and a very lucky shot with a ballista bolt managed to hit the dragon in the eye mid-flight, piercing into her brain and killing the dragon instantly. Rhaenys apparently died in the fall but her body was never recovered. Meraxes's death was a stunning blow to the Targaryens.
 * The TV episode didn't expend exposition on the history of how Meraxes died, given limited time, though this is fully explained in the Season 5 Blu-ray animated featurette "Dorne (Histories & Lore)". Instead, Qyburn cites that Drogon was wounded in the ambush at Daznak's Pit in Meereen as proof that Daenerys's dragons aren't invincible. The writers actually admit in the Blu-ray commentary for that episode that Drogon was able to be wounded with spears in that attack because he was just a juvenile at the time - which is true. Dragons' scales get thicker and harder as they age, until fully adult dragons' scales are practically impervious to swords, spears, or projectiles. Contrary to myth, a dragon's underbelly isn't any more soft or exposed than the rest of its hide: the eyes are the only weak spot on an adult dragon, the only part of them that isn't covered by their armored scales. There are historical examples of juvenile dragons being injured with human weapons, but the only thing that can pierce an adult dragon's hide is really another dragon. After Meraxes died, subsequent wars involving dragons did shift tactics to try to aim for their eyes with heavy projectiles - but the dragon-riders were very wary of this as well, so they were more careful to make quick bombing-runs on ground targets and evade projectile fire. A major example is the Siege of Rook's Rest during the Dance of the Dragons, when Aegon 's forces did try to shoot the adult dragon Meleys in the eyes, but her rider successfully evaded their fire. Ultimately, no other dragon was ever killed again by shooting it in the eyes. Vermax was also killed by human action in the Dance, though in that case it was a younger dragon and his foes hurled grappling hooks in his path, so he ended up impaling himself with more force than a human weapon ever could.
 * It's possible that Qyburn's custom ballista is actually going to be present in the next novel, given how it evokes the details given only in the novels about how Meraxes died: when they practice shooting it, they even aim directly for the eyes of a dragon skull.
 * It's unclear how effective Qyburn's ballista weapon will actually be, given that they tested it by shooting at a stationary skull, while a live dragon is a moving target. It did manage to pierce dragonbone, which is stronger than steel, but a live dragon would be covered in a thick layer of armor scales.
 * The Making Game of Thrones blog made an update post for this episode, explaining that all of the dragon skulls in the Cersei scene are real props, not CGI. First the art department made 3D sculptures, then the props department made full-sized skulls based on them out of polystyrene. Head sculptor Darren Fitzsimons stated that the prop of Balerion's skull is "about 30 feet long, 11 feet high, and 16 feet wide," and it took his team six weeks just to sculpt it (before painting and plastering). They kept a real sheep skull in their office as a comparison when making the surface texture. In the books, it is said that Balerion was so large that he could comfortably swallow a war-horse whole, along with its rider.
 * Notice that the dragon skulls are all different sizes, because they died at different ages - one of them is even no larger than a dog's head. Several characters have remarked in prior seasons (as in the books) that the dragon skulls got increasingly smaller the more recent they were - implying that younger generations of dragons got stunted through inbreeding. This wasn't true of most dragons, who simply died young in the Dance of the Dragons - but the absolute Last dragon was indeed a stunted, sickly, inbred creature who died young, not much bigger than a dog. In Season 1, Viserys mentioned to Doreah that the more recent dragon skulls were smaller until the last was no bigger than a dog's, and in Season 4, Tywin repeated this information, dismissing that the last dragon's head was the size of "an apple" (exaggerating), though Joffrey pointed out that the oldest skull was the size of a carriage.
 * Arya previously stumbled upon the preserved dragon skulls in the catacombs below the Red Keep in Season 1's "The Wolf and the Lion".
 * As Viserys explained in Season 1, the dragon-skulls used to be put on display along the sides of the throne room, but they were removed when Robert seized the crown. He didn't know what happened to them and thought Robert might have just had them smashed to pieces, but Cersei explains here that he kept them stored in the dungeons levels as a sort of trophy.
 * When Cersei first enters the catacombs with the dragon skulls in them, she walks past tattered old Targaryen dragon banners on the floor. This is a detail from the books, in which other characters who pass through this way (such as Tyrion and Jaime) spot them, put away there much like the dragon skulls.
 * Cersei Lannister's description of Daenerys Targaryen to demonize her and convince several lords to switch back to the Lannister side is filled with half-truths, which while not complete fabrications, are exaggerated or taken out of context (which makes them more effective than total lies). The accusations against Daenerys are similiar to the Liberation of Slaver's Bay ("Breaker of Chains"). The slave masters spread lies and half-truths to terrify the slaves.
 * Daenerys’ Targaryen's Unsullied are described as a slave army, ignoring the fact that the Unsullied are loyal as Daenerys has freed them and has given them a sense of self-motivation. ("And Now His Watch Is Ended").
 * That Daenerys is leading an horde of Dothraki "savages" - which is technically the truest statement, as the Dothraki do have a feared reputation ("Blood of My Blood"). But all the things she accuses the Dothraki of - pillaging, raping, burning villages - are things the Lannister armies themselves have been doing in the Riverlands for the past few years of war.
 * That she crucified "hundreds" of nobles in Slaver's Bay in Season 4's "Oathkeeper") - they were slaver-nobles, and she only crucified exactly 163 of them, specifically to pay them back for when they did the same thing, crucifying 163 slave children in "Two Swords" along the road to Meereen in an attempt to frighten her.
 * That she fed nobles to her dragons when she got bored with crucifying them - she only did that one or two times, not out of boredom or sadism but as a calculated means of execution to try to scare the rest into not supporting the ongoing insurgency against her ("Kill the Boy"). Cersei has done far worse for more flippant reasons.
 * She stresses that Daenerys is the Mad King's daughter and focusing on his tyrannical reign, even though Daenerys was born after her father died. She also doesn't bring up Daenerys's actions to end slavery in Meereen.
 * Cersei's accusations about the Dothraki to the lords gathered before the Iron Throne are technically accurate - that they will burn their villages, rape their women, butcher their children - but are also hypocritical. George R.R. Martin intended this in the books, highlighting how much of stereotypical Fantasy literature treats their analogue of medieval European knights as the "good" faction, with fantasy analogues of foreign non-white cultures depicted as villainous foreign hordes. Martin wanted to stress that in real medieval Europe, knights committed all kinds of war atrocities, the exact same things they accused other cultures of, i.e. English knights accusing that if the Mongols or Muslim powers invaded, they would rape, pillage, and burn their lands...even as the English were doing the exact same things in France and Scotland. The first novel/TV season includes characters like Robert Baratheon warning of the "barbarism" of the Dothraki, but then in the second novel/season the Lannisters themselves under men like Gregor Clegane and Amory Lorch conduct a campaign of mass torture and rape throughout the Riverlands. At the very start of the story, the Dothraki are also shown enjoying fights to the death at weddings - "a Dothraki wedding without at least three deaths is considered a dull affair" - only for Tywin Lannister to then engineer the massacre of the Starks at a wedding, breaking guest right. Tywin, Cersei, and others deriding the Dothraki as "savages" is supposed to be hypocritical, in-universe.
 * Randyll Tarly, Samwell's father, returns in the episode by travelling to King's Landing. During conversation, Jaime Lannister cites him as the only one who ever defeated Robert Baratheon, during the (Battle of Ashford); this was previously mentioned in Season 5's "Kill the Boy" by Stannis Baratheon to Samwell Tarly, after he realizes he is Randyll's son.
 * Randyll Tarly is often portrayed in the novels in a quite negative light, especially his behavior toward Sam and Brienne, but even if he's described as a ruthless and stern man, he is not outright sadistic, often dispensing strict justice that is nonetheless within the bounds of the law, similar to Stannis Baratheon. In this episode he proves to be an honorable person as well: reluctant to break his oath to the Tyrells, and open in expressing his negative opinion about both the Lannisters and the Freys - bluntly referring to the destruction of the Great Sept, the killing of Aerys, and the Red Wedding.
 * It is unclear if Randyll will do the same in the next novel, but due to various story condensations this may be representative of what several other characters will do. As the episode acknowledges, Randyll fought for the Targaryens in Robert's Rebellion, as did the rest of the Reach. On the other hand, rather than depicting him as blindly breaking ranks with the Tyrells and new Targaryen claimant to serve the crazed Cersei, it depicts him as very conflicted, only grudgingly switching to Cersei's side out of fear of the Dothraki (who do have an earned reputation as pillaging conquerors) - even the Mad King never brought a Dothraki horde to Westeros. He also says he is wary of what Cersei might do to his people if he crosses her, given that she just demonstrated that she is willing to massacre hundreds of innocent civilians to achieve her goals. Thus, while for various reasons Book-Randyll might not do this, with so many of other storylines omitted, the TV show doesn't really break its own internal logic to have TV-Randyll do this (only very grudgingly siding with Cersei).
 * Dickon Tarly (Samwell's brother) was recast starting in this episode: Freddie Stroma played him in his one, debut episode in Season 6, but he couldn't return for Season 7 due to a scheduling conflict. The role is now taken up by actor Tom Hopper. As a wink to the audience to explain the change, when Jaime meets the Tarlys he doesn't recognize Lord Randyll's son and mistakenly asks if his name is "Rickard", causing him to announce to both Jaime and the audience that he is in fact Dickon Tarly. "Rickard" is the name of Ned Stark's father but it is also a fairly common name in Westeros.
 * Randyll Tarly accurately points out in the throne room scene that Daenerys Targaryen has three adult dragons, and her ancestor Aegon I Targaryen managed to conquer the Seven Kingdoms with only three dragons as well - admittedly, bigger dragons, but she has a much larger army, and even the support of the Tyrells and Martells.

At Oldtown

 * It is unclear why Sam gave Jorah rum as an anesthetic, rather than milk of the poppy, which is commonly used in Westeros for that purpose (it is their version of morphine). Even without any medical background, Sam should have known that. It's possible that he couldn't take any without being noticed, when Ebrose forbid from trying the experimental treatment - though this wouldn't explain how he did manage to acquire all of his surgical tools and ingredients to make the anti-greyscale medical ointment.
 * An explanation could be that the access to milk of the poppy is limited and strongly supervised, like in modern days the access to morphine for everyone in a hospital. That Sam could get his hands on everything else is less surprisingly, because he is a maester in training, was seen assisting the Archmaester in autopsies and therefore able to take everything that is not restricted.
 * In the books, Samwell was actually by Jeor Mormont's side after he was mortally wounded during the Mutiny at Craster's Keep (in the TV version his attacker just keeps stabbing him until he dies, and a large fight breaks out, so Sam flees). Jeor's last words were to beg Sam to pass on a message to Jorah: "Tell my son. Jorah. Tell him, take the black. My wish. Dying wish". He didn't think Jorah was beyond redemption but wanted him to join the Night's Watch as he should have instead of fleeing into exile. So far in the books, Jorah has not been made aware of his father's dying wish.
 * In the novels, Archmaester Ebrose is specifically the archmaester of medicine, and he is indeed one of he best medical minds in all of Westeros. Moreover, he is mentioned as authoring several major studies on infectious diseases (including dangerous plagues from other continents, such as the "butterfly fever" from Naath, Missandei's island home).
 * Several callbacks are made to previous information given about Greyscale in Season 5: Sam recalls meeting Shireen Baratheon, and how she was cured of greyscale as a baby by Maester Cressen (though it left her face scarred). Ebrose counters by pointing out information also from the books: that greyscale can rarely be cured in infants or children, but not adults, and only if it is treated fairly early - Shireen was a baby and it was treated early, but Jorah is an adult with an advanced case, and thus beyond known treatment. Ebrose also says that Jorah should have cut his arm off to stop the spread (which sometimes works but often doesn't), and the only remaining option (besides suicide) would be to ship Jorah to the ruins of Old Valyria with the stone men. Ebrose also says that greyscale takes years to actually kill someone, leaving them in great pain for perhaps 10 to 20 years. The loose figures given in the novels are around 5 to 10 years, though it is not unheard of for someone to live 20 years with it. The novels only vaguely mention that when the infection grows inwards and starts warping the flesh of the brain, it can drive victims to madness, without giving a time scale for it; in this episode, Ebrose thinks Jorah might have only 6 months at best before he goes crazy from it (and he was infected nearly 2 years before).
 * The book that Sam was reading in the preceding episode seemed to hint that the cure for greyscale was to consume powdered Dragonglass - though the maester who wrote it also doubted it would work. It's unclear what Samwell made the medical ointment out of that he used on Jorah.
 * The novels note that Greyscale-scarred flesh is hard and deadened, so it doesn't actually feel any pain. After his run in with Stone men while on a boat in the books, Tyrion is told to prick his fingers with a knife everyday to test if he caught greyscale, and he follows that advice: if he started losing sensation in one of them he'd have had to cut it off in hope of stopping its spread. Jorah is in a great deal of pain in this episode - though Sam says he's cutting through the greyscale scars, down to the next layer of still-living flesh, which can still feel pain. "Flaying" might not be an accurate term for what Samwell is doing to Jorah here: that involves peeling back the thin layers of skin, but Samwell is cutting off flesh warped by greyscale, with a scalpel.
 * There is no "Archmaester Pylos" in the novels. There is a different character named Pylos, an ordinary-ranking master, who served as the elderly Cressen's assistant at Dragonstone and who was being prepared as his eventual replacement. Of course, there might be more than one person named "Pylos" in all of Westeros. Given that maesters give up their family names when they join the order (those who are from noble families), it's unclear how they distinguish maesters who happen to have the same name (i.e. if there's more than one named "Pate", a common name in Westeros).
 * Both of the maesters that Ebrose mentions who wrote history books he judges were mentioned in past episodes, both were invented by the TV series, and both of their descriptions in this episode match their prior descriptions:
 * Ebrose remarks that "Archmaester Ch'Vyalthan" wrote very well cited research - to the extent that, while factually accurate, his prose style is very boring and legalistic. This is a call-back to Season 2, when Tyrion was reading Ch'Vyalthan's book, An History of the Great Sieges of Westeros and remarking on it to Bronn. Varys then came into the room and noticed what he was reading, and said it was a thrilling subject, but it's a shame that Ch'Vyalthan wasn't a better writer ("The Prince of Winterfell").
 * Conversely, Ebrose then remarkes that Maester Vaull had a very entertaining and florid prose style - to the extent that "half" of what he wrote was just made up or editorialization. In Season 4, Samwell actually read one of Vaull's books in the library at Castle Black, talking about the savagery of the wildlings, hyping up that every last one of them is a sadistic cannibal, tortures their victims, etc. Maester Aemon then chided Samwell that Vaull made most of that up, assuring him that the closest Vaull even came to seeing a wildling was the very library they were standing in.
 * Samwell says the title of the book Ebrose is working on, An History of the Wars Following the Death of Robert I, could be a bit more "poetic". This seems to be a reference to A Song of Ice and Fire and/or Game of Thrones itself, both of which are poetic titles.
 * It may also be a callback to Season 4, when Sam asked Jon what having sex with a girl was like (with Ygritte): Jon couldn't give a very good description, then just dropped it by saying he wasn't a poet, if that's what Sam wanted.
 * When George R.R. Martin wrote Samwell Tarly, he was partially influenced by Samwise Gamgee from The Lord of the Rings: both are the best friend of the lead character, somewhat overweight, sort of an everyman who isn't originally very brave or a famous warrior, and both are called "Sam" for short. At the end of the story, it is revealed that it is based on an in-universe history book written by the main characters: Bilbo Baggins, then Frodo Baggins, and then after Frodo leaves, Samwise finishes up writing some of the loose ends. Similarly, Game of Thrones might be setting up that Samwell Tarly is going to write an in-universe history book about all of these events in Westeros, on which the book series is likewise based (and therefore the poetic titles are Sam's invention). This would be consistent with the Archmaester instructing Tarly "about the art of writing history".
 * This doesn't mean that Sam could be the literal author of the series A Song of Ice and Fire, as the story contains a great many characters that Sam has never met and many events for which he was not present. However, it is possible that, like in The Lord of the Rings, Sam will be writing in-universe about the events of the series.
 * It's worth noting that the phrase "the song of ice and fire", like "the game of thrones", appears in the novels, but unlike "game of thrones", it has yet to appear in spoken dialogue. During her visit to the House of the Undying, Daenerys sees a vision of her brother Rhaegar saying "His is the song of ice and fire", apparently referring to his newborn son, Aegon. Thus under this theory, the title of the series may not be Sam's invention, but instead inspired by something else, perhaps something Sam read at the Citadel.
 * Screencaps reveal the content of Jorah Mormont's suicide note, which he writes in his chamber while eyeing his sword: "Khaleesi, I came to the Citadel in the last hope that the maesters could treat me, as you ordered. Even with all their arts, I am beyond any cure but the grave. I have had a longer life than I deserved, and I only wish I could’ve lived to see the world you’re going to build, standing by your side. I have loved you since the moment I met you - Jorah"
 * The camera cutting from Samwell sawing at Jorah's scaley skin to a bowl of potato stew in Arya's scene was specified in the script, not an invention of the director.

On the Narrow Sea

 * Ellaria's comment about Dornish red wines being the "best in the world" is a reference to the debate between the Dornish red and the Arbor gold.
 * Although Theon's actions at the end of the battle first seem cowardly, many viewers pointed out that Theon essentially had no choice. The battle was already over by that point, and Theon was drastically outnumbered. Furthermore, he was still physically weak from his years in captivity, and never would have been able to defeat Euron in a battle anyway. If he had tried to attack Euron, it very likely would have ended in both his death and the death of Yara.
 * One possible reason that Euron was able to win so easily is that Yara's crew couldn't figure out whom to fight. This battle was essentially iron born vs iron born, so it would have been very difficult for Yara's crew to tell friend from foe. Factor in the fact that they were fighting in the pitch black, fireballs flying everywhere, and the enemy ships and crew were bearing the same exact signias that they were.
 * Ellaria flirting with Yara aboard the Black Wind appears to be a callback to the sixth season where Yara kisses a courtesan in Volantis in front of Theon, making him visibly uncomfortable after his castration by Ramsay Snow. Being bisexual herself, Ellaria invites Theon for a threesome, unaware of what Ramsay did to him. Furthermore, Ellaria treats Theon rather coldly, demanding that he refill her jug; though Yara tells Ellaria that Theon is not their servant, Theon begrudgingly claims he does not mind, possibly due to having served Ramsay as a servant for nearly two years.
 * When Ellaria says there is a boy in every port in Dorne, Yara responds with "A boy, a girl. Depends on the port." This implies Yara is bisexual. Yet Gemma Whelan stated in an interview that Yara was gay.
 * When the Sand Snakes are discussing who will get to kill whom when they lay siege to King's Landing, Nymeria comments that she wants to kill The Mountain, in revenge for murdering Oberyn.
 * In the novels, the Sand Snakes believe that the Mountain is dead. This is not just exclusive to them: in the novels, it is widely believed that Gregor Clegane died of his wounds after his battle with Oberyn, which is part of the Ser Robert Strong identity mystery. In order to appease Dorne, the Mountain's skull was brought to Sunspear by Ser Balon Swann of the Kingsguard, and was presented to Doran Martell, Arianne Martell, and Obara, Tyene and Nymeria Sand. Tyene herself confirms that if the poison her father used so much as broke the Mountain's skin, then Gregor is dead. Obara, however, suspects trickery, but Nymeria points out that if anyone matching Gregor's size and stature appears again in Westeros, Cersei will be proved a liar.
 * Euron Greyjoy's proposal of a "gift" for Cersei seems to be explained in this episode. Apparently aware of how Myrcella Baratheon was killed, Euron attacks Yara and Theon's fleet but makes sure to take Ellaria and Tyene Sand prisoner instead of killing them; Ellaria and Tyene were primarily responsible for Myrcella's murder, since Tyene synthesized the poison and Ellaria administered it via a kiss. Euron apparently intends to bring Ellaria and Tyene before Cersei so she can take revenge for Myrcella. Also, Cersei could use Ellaria as a hostage to force Dorne into siding with her against Daenerys, much like how the Mad King used Elia Martell as a hostage during Robert's Rebellion to ensure Dorne's support. The capture of Yara can be used as evidence that Yara has no claim to Salt Throne since Euron followed the Old Way and paid the Iron price according to Ironborn culture. This was a running point in the novels. When Asha was captured by Stannis, she realized that her defeat, combined with her failure at Kingsmoot, meant that the Ironborn would never follow her.
 * Of note, Tyrion Lannister brings this up during Daenerys's war council, openly accusing Ellaria of poisoning Myrcella, an innocent girl, in cold blood, until the argument is broken up by Daenerys herself. Following the airing of "The Winds of Winter", it was widely speculated that Tyrion, as Daenerys's hand, would demand justice against Ellaria for murdering his niece; the deaths of Obara and Nymeria and the abduction of Ellaria and Tyene by Euron have made this less than likely.
 * In a sense of irony, Obara and Nymeria are killed by Euron Greyjoy, who uses their own weapons against them, impaling Obara through the stomach and pinning her from the ship's bowspirit, and strangling Nymeria to death before hanging her corpse from the ship. Obara literally stabbed Trystane Martell in the back with her spear, while Nymeria appeared with the intention of strangling Trystane with her whip had Obara not interfered. Their cold-blooded murder of Trystane has come full circle with their deaths, since although Euron's motive was clearly not avenging Trystane's death (no more than Jaime's maiming by Locke was meant to be a payback for what he did to Bran), it can considered poetic justice that Obara and Nymeria were killed by the same weapons they used to butcher their own cousin.
