Differences between books and TV series - Season 5

A list of differences that can be found between the fourth season of the TV series and, roughly, A Feast for Crows and A Dance with Dragons, the fourth and fifth novels of the A Song of Ice and Fire book series. The two novels take place concurrently, with the fourth novel detailing events in the Seven Kingdoms, while the fifth novel follows events outside of them (at the Wall, Arya and Tyrion in the Free Cities, and Daenerys in Slaver's Bay). Originally the fourth and fifth novel were going to be one very long novel, but Martin had to split them apart because it had grown too large. The TV series chose to simply intercut material from the two - which, in a sense, is recreating the original effect that Martin intended.

The Wars to Come

 * Cersei was accompanied by Melara Hetherspoon and Jeyne Farman, when she went to see Maggy. It was Jeyne, who was terrified of Maggy and she even escaped when Maggy woke up. Melara was described as being even more brave than Cersei and was more than eager to meet Maggy. TV Melara is a condensation of both girls from the novels. She retains Jeyne's cowardice but still accompanies Cersei as book Melara did.
 * Maggy's prophecy has several differences in the books: Melara Hetherspoon is also interested in hearing her future so she also takes part, Maggy predicts that Robert Baratheon will have sixteen children rather than twenty and she predicts the deaths of both Cersei Lannister and Melara, but the former at the hands of the "valonquar", the Valyrian term for "little brother", whom Cersei believes to be Tyrion.
 * Maggy's physical appearance is quite different in the show. In the books she is very old, wrinkled, and has no teeth left. She is also nicknamed "Maggy the Frog".
 * Robin never did any strenuous physical activity, as the slightest physical exertion caused him to have seizures.
 * Petyr Baelish never agreed to foster Robin Arryn at Runestone. In fact, lord Royce along with other lords declarants tried to forcibly take Lord Robin with them and Lord Baelish managed to prevent that from happening.
 * Brienne never told Podrick to leave, she was in fact never less than polite to him.
 * White Rat was named Stalwart Shield, and he was killed after leaving the brothel. It also took 6 Sons of the Harpy to kill him, though he was able to stab one before dying. His body was also bought to the throne room for everyone to see.
 * The Sons of the Harpy did not leave a mask when they killed, they painted a Harpy in blood near the body. In fact, they were never seen in the books, and they were never described wearing masks.
 * White Rat was described as being the Sons' first victim in TV series. In the books, the Sons have already killed before, but their victims were mostly homeless people. Stalwart Shield was the first Unsullied to be killed which indicated, that the Sons have become more daring.
 * The request to open the fighting pits came from Hizdahr himself, not from Yunkish people. In fact, Hizdahr was never sent to negotiate with Yunkai.
 * Daario was not present in Meereen at that time as he was sent to negotiate with Lhazareen.
 * Cersei never thought Jaime had released Tyrion but suspected the Tyrells, because a golden coin of House Gardener was found in the possession of the missing galoer, who disappeared the same night Tyrion did.
 * At that point in the books, Tywin's body was already in state of decomposition and a foul stench emanated from the body, so nobody wanted to come close to the body.
 * According to the TV series, this was the first time Lancel appeared in public after the Battle of Blackwater but in the books, Lancel has already appeared at Joffrey's wedding. He was also much weaker at that time, being extremely thin and with white hair. He became very devout after he recovered, but he never joined the Sparrows. In fact, Sparrows were not present in King's Landing at that time.
 * Varys never went to Pentos with Tyrion. It was Illyrio Mopatis who discussed Daenerys with Tyrion.
 * Jon never went to see Mance, and Stannis never asked him to convince him to kneel.
 * Stannis in fact never gave Mance a choice between kneeling or burning, he simply burned him.
 * Sam, Gilly, Janos Slynt, Tormund, Selyse, Shireen and Davos were not present at the execution.
 * Mance was not very calm during his execution, he was screaming and begging until his death. He was also burned in a wooden cage hanging over a pit of fire north of the Wall, in front of a thousand wildling prisoners.
 * It was not Jon himself but several archers on his orders who shot Mance.
 * Lancel Lannister never joined the Sparrows. Instead, he joined the Warrior's Sons, a division of highborn knights devoted to the Seven.

The House of Black and White

 * Petyr and Sansa never leave the Vale and they never meet Brienne and Podrick.
 * Arya does not knock on the door to the Temple of Black and White, she opens the door and walks right in and no one wanted to prevent her from entering. The Faceless Man she encountered had a different appearance. Instead of being an old man with wrinkled and sickly face, he is described as a cloaked figure with only a skull for a face. When Arya told him her name, he changed into kindly old man, not into Jaqen H'gharr. The books made clear the Kindly Man is not Jaqen H'gharr while in TV series, the person is apparently the same.
 * Ellaria did not wish for war with the Lannisters to avenge Oberyn's death. Quite the contrary, she is firmly opposed to any further bloodshed. This role is filled by Arianne Martell, Doran's daughter, eldest child and heir, who has been cut from the TV series so far.
 * It was not Ellaria but Obara, who encountered Prince Doran in the Water Gardens. Doran was not watching Myrcella and Trystane, but children swimming in the pools. Myrcella and Trystane were in fact not present at the Water Gardens as they were both at Sunspear, which is several miles away.
 * Jaime never goes to Dorne to rescue Myrcella, since the Martells never send Cersei a threat. In the books, Jaime does leave the capital on Cersei's orders, but to lead the Lannister armies in putting down the last few Riverlords loyal to Robb Stark who are still at arms.
 * Bronn does indeed marry Lollys Stokeworth, and never goes to Dorne with Jaime.
 * Mace Tyrell never serves as Master of Coin; in the novels, he puts himself forward for the position of Hand of the King and offers one of his uncles to serve as Master of Coin during Tywin's funeral, but Cersei (not wanting any Tyrells in a position of power close to the crown) brusquely refuses him and appoints two of her own cronies to the posts. Kevan later rebukes her for this, saying that while Mace would make a poor Hand, it is unwise to make him an enemy. Cersei laters dispatches Mace to lay siege to Storm's End (again) and another of his vassals to besiege Dragonstone to rob Stannis of his last holdings in the south.
 * Kevan does deny Cersei, but not for Master of War (a title which never exists in the books), but as Hand of the King.
 * He also refuses for a different reason. Before he died, it had been Tywin's intent that Cersei return to Casterly Rock and have no further say in the governance of the realm or Tommen's upbringing (as Tommen is 9 at this point in the books). Kevan demands Cersei name him Regent, to rule until Tommen comes of age, and that she leave King's Landing in accordance with Tywin's plan. Cersei responds by throwing her wine in his face. In response, Kevan makes it plain he thinks her an unfit mother and is aware that Tommen and his siblings are the product of incest between Cersei and Jaime. Kevan then retires to Casterly Rock; to spite him, Cersei gives the positions of Warden of the West and Castellan of Casterly Rock (both positions Keven would be best suited for) to lesser members of House Lannister. Jaime also fears Cersei might try to assassinate Kevan (both for his defiance and his awareness of their affair).
 * Although Areo's skin color is never described in the books, it's most likely white, as he is from Norvos. He is also described as having white hair and a beard.
 * Varys does not accompany Tyrion on his journey to meet Daenerys. Rather, he is accompanied by Griff and his ward, Young Griff, as well as Ser Rolly Duckfield, Septa Lemore and Haldon Halfmaester, all of whom have been cut from the TV series.
 * Daenerys never sees Drogon atop the pyramid. In fact, the last time she saw him was when they wanted to capture him.
 * Mossador does not kill a Son of the Harpy against Daenerys's wishes. In fact, he is killed by the Sons of the Harpy. Also, he is Missandei's brother in the books and his death devastates Missandei.
 * Jon refuses Stannis's offer of legitimization as a Stark for several reasons, including Melisandre demanding he burn down the Godswood of Winterfell and convert to the Lord of Light.
 * Sam and Gilly never met Selyse and Shireen as they were both at Eastwatch and arrived at Castle Black much later. Thus nobody taught Gilly to read.
 * The election for Lord Commander of the Night's Watch has several differences:
 * There are several elections held, as a Lord Commander is only elected when he has 2/3s of the vote or more.
 * It is at first a very close vote between Janos Slynt (Ser Alliser withdraws early on due to barely any votes), Denys Mallister and Cotter Pyke, with Janos gaining votes each time.
 * There were also more candidates such as Bowen Marsh, Othell Yarwyck, Hobb and Edd
 * Sam lies to Denys and Cotter (who each loathe the other), convincing Denys that Stannis will force Cotter to be elected and Cotter that Stannis will force Denys to be elected. He then convinces each to support Jon instead.
 * Jon ultimately wins by a huge margin, not a single vote.

High Sparrow

 * Medger Cerwyn died in Harrenhal as a prisoner during the War of the Five Kings and his son Cley Cerwyn was killed when Ramsay sacked Winterfell.
 * Due to Tommen Baratheon being nine years old, he and Margaery Tyrell have currently not consummated their marriage.
 * It is not the High Septon (who has died by this point in the books) but a Septon vying for the position who is dragged out of a brothel and publicly humiliated by the Sparrows.
 * It is not Davos but Melisandre who speaks to Jon and advises him on how he can best act in dealing with Stannis.
 * Jon's steward is an Oldtown boy named Satin, who was raised as a whore.
 * Jon Snow did not appoint Ser Alliser to be First Ranger.
 * Jon's execution of Janos Slynt differs in several ways:
 * He gives him the position the day before executing him. He lets Janos think about it overnight, though he did immediately refuse.
 * Jon orders him to go during breakfast, not during several other announcements.
 * Jon is initially going to hang Janos, but changes his mind. Janos smiles, thinking he's being spared. Jon then orders a block to be brought for beheading and Slynt's confidence evaporates as he realises Jon's threat to behead him is real.
 * Littlefinger does not intend to marry Sansa to Ramsay Bolton, he instead plans to marry her to Robin's heir Harrold Hardyng. Littlefinger also disguises Sansa's childhood friend Jeyne Poole as Arya Stark and marries her to Ramsay instead.


 * Petyr and Sansa also never go to Winterfell.


 * Tyrion does have sex with the whore in the brothel, but only picks her because all the others are quite old.
 * The whore, while Westerosi in looks, does not speak a word of Westerosi.
 * Tyrion is not captured by Jorah in Volantis, but in a Volantene-aligned city called Selhorys.
 * Tyrion is not with Varys when he's captured, but with a man aiding Ilyrio named Haldon Halfmaester.
 * Jorah kidnaps Tyrion not stealthily, but in full view of everyone in the brothel. When the brothel owner tries to stop him, Jorah draws his sword and the owner relents.


 * Jorah had the Daenerys lookalike whore on his lap when he noticed Tyrion.


 * When Arya disposes of her possessions in the canal, she returns to the House of Black and White completely naked. (Since actress Maisie Williams was 17 at time of filming, she remained clothed.)


 * Arya hides Needle in a hole under the steps leading up the House of Black and White.

The Sons of the Harpy

 * Barristan Selmy is not slain by the Sons of the Harpy, he is still alive and also a POV character in the latest novel.
 * Sansa Stark is never promised to Ramsay Snow, never in Winterfell, and thus, does not visit the crypts.
 * Jaime and Bronn never intend to, nor do they sail to or set foot on Dorne to rescue Myrcella. In the books, Bronn is wed to Lollys Stokeworth whilst Jaime is in the Riverlands trying to get Brynden Tully to surrender Riverrun without bloodshed. Cersei sends another Kingsguard, Balon Swann, to take Myrcella back.
 * Cersei never sends Mace Tyrell away to Braavos with Meryn Trant. Instead, she sends him to besiege Storm's End, Harys Swyft and Rafford "the Sweetling" are sent to Braavos instead.
 * Littlefinger does not intend to return to King's Landing.
 * Loras Tyrell is never arrested for his sexuality. Instead, Cersei forces him to lay siege to Dragonstone, hoping he will die, and in fact he is reported to have been wounded.
 * The Faith Militant did not carve the seven pointed stars onto their foreheads.

Kill the Boy

 * Daenerys did not intimidate the head of each family of Meereen using her dragons. Instead she took hostages (children) from each of the noble families to serve as her "cupbearers". She also demanded blood money from each family for each of her followers or soldiers killed by the Sons of the Harpy.
 * She incidentally never threw Hizdahr in jail, although Ser Barristan did later.
 * Jon first sent a wildling envoy named Val North of the wall to find the wildlings after the battle, who were led by Tormund himself, as he was not captured during the battle. Later, when Tormund came back and told Jon about the many Free Folk at Hardhome, the Lord Commander decided to send many of the Night's Watch ships and men to the ruined settlement to save them. Later, Jon and Tormund planned to go themselves.
 * Jon wanted the Wildlings to come south of the Wall not to settle it (that was Stannis' idea), but to occupy the empty castles along the Wall to hold them for when the White Walkers attacked.
 * Sansa never sees Theon, because in the novels, it is her friend Jeyne Poole, masquerading as Arya Stark, who is betrothed to Ramsay. Jeyne does indeed see Theon, who immediately recognizes her but remains silent in order to protect her.
 * Walda Bolton is not believed to be pregnant, although Roose does mention to Reek that if they had any children he suspects Ramsay would kill them.
 * Although Ramsay's mother took him to the Dreadfort when he was a baby he did not stay there, Roose instead arranged for them to stay at the mill once owned by his mother's deceased husband and Ramsay did not move to the Dreadfort until two years before the The War of Five Kings, also the current status of Ramsay's mother is uncertain.
 * Shireen and Selyse were indeed left at Castle Black when Stannis marched, along with a dozen knights and guards, and Melisandre.
 * Davos did not march with Stannis, he was sent to negotiate with Lord Manderly at White Harbor, hoping to get him to side with Stannis.
 * Jorah and Tyrion never went near Valyria, as in the books anyone who sails within hundreds of miles of it vanishes without a trace. Sailors never go through the Smoking Sea. Tyrion, however, did encounter Stone Men, but in The Sorrows region of the river north of Volantis. Later, with Jorah, they sailed around Valyria instead of through it.
 * Having not encountered Stone Men, Jorah was never infected with Greyscale. Tyrion's companion who saved him from the Stone Men and ended up infected was actually Jon Connington.

Unbowed, Unbent, Unbroken

 * Jorah is not made aware of his father's death.
 * Tyrion and Jorah are captured when slavers board their ship rather than on land.
 * Littlefinger has not returned to King's Landing since he first left for the Eyrie.
 * Cersei does not know where Sansa is and has no intention of attacking House Bolton.
 * While Myrcella Baratheon and Trystane Martell get on well it's not known if they have romantic feelings for each other.
 * The Sand Snakes planned to spark a war with the Lannisters, but with different means —Obara wanted to go to war directly, Nymeria wanted to assassinate certain key Lannisters and Tyene wanted to make Myrcella Queen of Westeros as their puppet, sparking the war they all wanted. However, they were all curtailed before they could even try to achieve their goals. It was a group led by Arianne Martell, Doran's daughter and heir, instead of Ellaria Sand, who tried to carry out Tyene's same plan: to crown Myrcella. No one planned to harm her.
 * During the skirmish with Areo Hotah, Myrcella is attacked and scarred by a rogue knight, Ser Gerold "Darkstar" Dayne, who flees capture, while the Kingsguard protecting Myrcella, Ser Arys Oakheart, makes a mad charge towards the Dornish forces and is killed by Hotah. In the TV series, no one on each side is killed.
 * In the books, Ellaria Sand does not play any part in the scheme involving Myrcella, yet she is still arrested along with her four young Sand Snakes, though only preemptively and not as a punishment.
 * Olenna Tyrell has not returned to King's Landing since the High Sparrow became High Septon. It is Mace Tyrell and Randyll Tarly who arrive in the capital, with the entire Tyrell army, to free Margaery by threat of force.
 * Margaery Tyrell was arrested due to rumors that she was unfaithful to Tommen, rumors that were mostly invented by Cersei.
 * Ramsay marries Jeyne Poole under the guise of Arya Stark, not Sansa.
 * Theon was forced to participate in Ramsay and Jeyne's wedding night by stripping her clothes and performing oral sex on her to "warm her up", before he is made to watch. In the TV series, he is merely forced to watch Ramsay force himself on Sansa.

The Gift

 * Tyrion and Daenerys have not yet met, though it has been confirmed to happen in the following novel.
 * Gilly is not nearly raped by brothers of the watch, thus Sam does not defend her.
 * Ghost never leaves Jon's side after they reunite in the books.
 * Aemon dies on a ship en route from Braavos to Oldtown. Additionally, his body has not been burned as of yet, but is being preserved in a barrel of alcohol until Sam has a chance to conduct a proper funeral.
 * Melisandre never asks Stannis to burn Shireen.
 * When Tyrion and Jorah are auctioned, Jorah did not fetch a good price, nor was he bought quickly. During captivity he refused nearly every order from the slavers and was thus beaten constantly and was branded on his face with a demon mask, the Volantene mark for a disobedient slave. He is eventually bought for less than 1/30th of the price the slaver paid for Tyrion.
 * Daenerys does not visit a single fighting pit until after her wedding to Hizdahr.
 * Olenna never outright says she killed Joffrey, nor does she meet with Littlefinger.
 * The Sand Snakes are imprisoned in comfortable rooms in the Tower of the Sun in Sunspear, not a dungeon. They are also each kept in a different room.
 * Lancel confesses his and Cersei's crimes (their affair and Robert's murder) to the second High Septon, who is killed for that reason by Osney Kettleblack at Cersei's command. Lancel admitted that also to the High Sparrow, but Cersei is not arrested due to his confession: she sends Osney to confess falsely to the High Sparrow that he has slept with Margaery, as a part of Cersei's scheme against her. Osney sounds so pleased to be so guilty, that it arouses the High Sparrow's suspicions. He has Osney tortured, then the truth comes out: Osney admits he has slept with Cersei, murdered the previous High Speton at her command and never touched Margaery. Cersei is thrown to jail. Later, she is confronted with all the accusations based on both Lancel and Osney's true confessions.

Hardhome

 * Jon's plan with Tormund in the TV series is an amalgamation of four different missions in the books: Jon first sent a wildling envoy named Val North of the wall to find the wildlings after the battle, who were led by Tormund himself, as he was not captured during the battle. During a ranging beyond the Wall, Jon encountered the giant Wun Wun and a small group of wildlings, who he convinced to come back to Castle Black with them. Later, when Tormund came back with the wildlings and told Jon about the many other Free Folk at Hardhome, the Lord Commander sent many of the Night's Watch ships and men to the ruined settlement to save them. However, wights surrounded the area and they were left stranded, so Jon and Tormund planned to go themselves and save the black brothers and wildlings both —however, this mission was interrupted. The TV series picked the Hardhome context of the latter two failed missions and ascribed it to the successful former missions of bringing Wun Wun and a few wildlings back to Castle Black and of sending a wildling envoy North and bringing thousands of Free Folk through the Wall.
 * Valyrian steel isn't confirmed to be resistant to the White Walkers' weapons and lethal to the Walkers themselves, though it is implied that is the case when Sam discovers textual references to "dragonsteel" as a weapon against the White Walkers, and they assume it means Valyrian steel.
 * Theon doesn't tell Sansa that Bran and Rickon is alive, as they not have seen each other since she left Winterfell.
 * Roose Bolton also lets out a host to fight Stannis in the snow, though it is a much larger one, instead of a small raiding party led by Ramsay, and Roose only does so when forced due to the rising tensions in the castle: The Freys and Manderlys are at each others' throats, so he decides it may be better if they abandon the castle and attack Stannis in the snow.
 * Ser Kevan does come back to preside over the small council after Cersei's arrest, but in the position of Lord Regent, not Hand of the King. Since Tommen is older in the show, he does not need a Regent anymore; Cersei was Queen Mother, and Kevan can't be Lord Regent. In the books, after becoming the Regent, Kevan appoints Mace Tyrell as the Hand of the King. Also, Qyburn is dismissed from Kevan's council.
 * As Tyrion and Daenerys have not met yet, Tyrion does not advise her on Jorah (who she does not know is in Meereen) or on any other matter. Though Daenerys is empathetic to the slaves and the poor, she never implies an end to feudalism were she to rule the Seven Kingdoms, which she does in the show when she talks about "breaking the wheel" of Great Houses that is crushing the smallfolk, including her own House Targaryen in the list.

The Dance of Dragons

 * Hizdahr zo Loraq isn't killed by the Sons of the Harpy, he married Daenerys before the events of Daznak's Pit and is currently still alive.
 * Doran sends Nymeria Sand to serve in the Small Council in King's Landing, not Trystane, though he does also send Trystane to the capital along with Myrcella.
 * In the books, the Sons of the Harpy do not launch an open attack on Daznak's Pit, though they do attempt to kill her by poisoning food on a buffet in the royal box (provided by Hizdahr). However, one of Daenerys' advisors eats the poisoned food instead. The remainder are left suspicious when they learn the items poisoned were ones Hizdahr was particularly encouraging Daenerys to try, causing many to suspect Hizdahr is either a member of the Sons of the Harpy or is in cahoots with them.
 * Drogon does not appear to save Daenerys; he is drawn to the Pit by the smell of blood and fresh meat from the numerous gladiatorial battles (some involving animals). When the Meerenese try to attack him, Drogon goes on the rampage, causing over 200 deaths as people are either killed by the dragon or trampled in the panic to escape. Only one person in the arena manages to injure Drogon- an animal handler called Harghaz who Daenerys suspects merely wants to make a name for himself as a dragonslayer. He manages to seriously injure Drogon before the dragon kills him.
 * Tyrion is present in Daznak's Pit in the books, except he is a dwarf riding on a dog as a show for the observers. He does contemplate revealing himself to Daenerys, only to stay silent when he sees Barristan Selmy (who is still alive at that point in the books), out of fear Barristan might prejudice Daenerys against him out of their shared contempt for House Lannister.
 * In the march to Winterfell, Stannis’ camp is left stranded by the heavy snowstorm, with little to no food, though this is due to a grueling march exclusively due to the weather—they are not raided by Ramsay Bolton or anyone else, though Roose Bolton is indeed forced to let out a host to meet Stannis in the snow, in order to alleviate tensions within Winterfell, as several fights and murders have broken out between the forces of various northern Houses and House Frey in the castle.
 * Due to the snowstorm, Stannis relents and lets the fanatics in his army sacrifice some criminals charged with cannibalism, instead of Shireen Baratheon. However, author George R.R. Martin has confirmed Shireen will be burned as a sacrifice in later books.
 * Arya does not see Meryn Trant in Braavos, nor does she persue him into a brothel. Instead, Arya follows Raff the Sweetling and tempts him in the Winds of Winter 'Mercy' chapter.
 * Meryn Trant has not shown any attraction towards children.

Mother's Mercy

 * Only Jon is confirmed to be dying in the books. Stannis, Selyse, Myrcella, and Meryn Trant are all still alive.
 * Samwell leaves for Oldtown earlier in the books, takes Mance Rayder's son and Maester Aemon instead of Gilly's son; also it was Jon's idea for Sam to go to Oldtown as he both wants someone to research the Others (White Walkers) in the Citadel's archives, and wants to keep Aemon and Mance's son out of Melisandre's hands, to keep her from having them burnt for use in her magic.
 * Jeyne (Ramsay's wife in the books) does not attempt to escape on her own, the escape attempt is triggered by wildlings sent by Jon Snow. The escape takes place before the battle, as the escapees realise their best chance is to link up with Stannis's army before the Bolton forces reach him.
 * Brienne and Podrick are still in the Riverlands when the battle at Winterfell occurs therefore it is highly unlikely that Brienne will kill Stannis.
 * Although Ramsay sends a letter to Jon Snow saying he defeated Stannis, it's not yet confirmed that he's telling the truth.
 * Theon didn't kill anyone during the escape attempt.
 * Arya has not killed Ser Meryn Trant, she instead killed Rafford "The Sweetling" and she only stabs him twice, Ser Meryn is still alive in the books.
 * Arya becomes blind before she kills Raff the Sweetling. She is punished for killing a brother of the Night's Watch who deserted and who she came across while in Braavos.
 * Myrcella does not show any awareness that the rumors that Jaime is her father are true.
 * Barristan Selmy rules Meereen while Daenerys is missing instead of Tyrion.
 * Jorah and Daario do not go to search for Daenerys, Daario is currently a hostage in Yunkai and Jorah is with Tyrion as a member of the Second Sons.
 * Varys is not believed to have been to Meereen since Daenerys took over.
 * Daenerys does not leave a ring behind as a breadcrumb. Drogon is at her side when the khalasar finds her.
 * Cersei's hair is shaved off completely.
 * Davos has not returned to The Wall since Stannis marched.
 * Jon's assassination differs from its book counterpart in several ways:
 * Jon receives an insulting letter from Ramsay Bolton, mentioning Stannis's death (which is unconfirmed in the novels) and demanding Jon to send Selyse, Shireen, Melisandre (who are all present at the Wall) and also Reek (who is nowhere near Castle Black and whose identity is unknown to Jon) to Winterfell. Jon, already full of hatred towards the Boltons, used the death threat in the letter as an excuse to make plans to march on Winterfell and destroy Ramsay. Jon makes a speech to the Watch and the wildlings, asking for volunteers to join him, and many from both groups do so. Shortly after that, he was stabbed in the courtyard by several brothers including Bowen Marsh – the reasoning apparently that Jon is actually betraying his vows by taking sides in a political dispute rather that ideologically betraying them by allying with the wildlings.
 * The assassination takes place with both Black Brothers and Stannis's men present, instead of just members of the Watch. There is a possibility that the TV assassination has been planned for quite some time, considering that it took place in the middle of the night with only mutineers present.
 * Of the Watch's First officers, only Marsh partakes is described as being one of the assassins: Yarwyck is not mentioned and Thorne is not only not the First Ranger, but isn't in Castle Black. All three are present at the assassination in the series.
 * It is not clear if Jon's decision was the actual reason or just a catalyst that lead to his assassination. In TV series, the primary reason seems to be his decision to let the wildlings through the Wall.
