Differences between books and TV series - Season 1

Winter is Coming

 * The TV series starts with three rangers of the Night's Watch going under the Wall. This scene is additional to the series because in the book, they have already been ranging for days.
 * In a book, the attack of White Walkers happens at the place several days riding north of the Wall. But in TV series, it happens in a forest close to the Wall the same day, the rangers leave Castle Black.
 * The White Walkers are mostly called Others in the books, especially by the people of the Seven Kingdoms. It is the wildlings that refer to them as white walkers.
 * In the TV series, Will discovers the wildlings massacred and their bodies brutalized. In the book, he says they appeared to be sleeping and likely froze to death.
 * The White Walkers have different appearance in the TV series. In book, they have white skin and reflective light armour. In the TV series, they have frozen grey skin, dark hair, and a brutal face similar to skull. Their bodies are darker and they don't seem to wear armour.
 * In the TV series, only Gared and Waymar Royce face the White Walkers' first attack, while Will is exploring the area. In the book, all three are present.
 * In the books, Ser Waymar Royce has a duel with the White Walker. In the TV series he is killed in a surprise attack.
 * The wight girl, who frightens Will in the series, is never mentioned in the book.
 * In the books, Ser Waymar Royce is transformed into a wight.
 * In the TV series, Gared is the second one to be killed by the White Walkers and Will escapes. In the books, Will is strangled by the wight of Ser Waymar Royce and Gared escapes. In the TV series Gared is beheaded by a White Walker as opposed to being killed by a wight.
 * The Winterfell soldiers capture of Will is not described in the book.
 * There are more additional scenes in series in Winterfell, which introduce the Stark family. Bran is shown practicing archery, while his father is watching him. The scene with needlework, which involves Sansa and Arya, is moved to the beginning of the series, before King Robert arrives. In the book, the scenes in Winterfell begin with the deserter's execution.
 * Arya is shown to be an accurate archer, while in the books, she doesn't know how to fire a bow and wishes she could learn.
 * ​Events of the TV series are seventeen years after Robert's Rebellion. The books begin fourteen years after, thus the Stark children are visibly older. Robb and Jon Snow are 17 instead of 14. Bran is 10 instead of 7 and Rickon's age is increased from 3 to 6.
 * The Stark girls' birth years are also altered to Sansa 13 instead of 11 and Arya is 11 instead of 9.
 * Likewise, the Royal children are older: Joffrey is 16 instead of 13, Myrcella is 12 instead of 8 and Tommen is 10 instead of 6.
 * Daenerys is 16 instead of 13.


 * In the TV series, Will is executed for desertion instead of Gared.
 * In the book, snow covers the grounds around Winterfell. In the TV series, there is no snow.
 * The scene in King's Landing introducing Queen Cersei and her brother Jaime is not in the books. It also shows the corpse Jon Arryn.
 * Daenerys Targaryen appears much later in the TV series. In the book, she is introduced, after Eddard Stark gets the news about Jon Arryn's death. In the TV series, she appears after the scene at Lyanna Stark's tomb.
 * Targaryens have violet eyes in the books, but these were dropped from the series. The showrunners have said that they did use purple contacts early in filming, but this interfered with the actor's performance as emotion is conveyed through the eyes.
 * Illyrio Mopatis's appearance is different to his description in the books. In the series, Illyrio is overweight and has dark brown hair flecked with grey with a forked beard. In the books, Illyrio is described as being morbidly obese with gold, oiled hair and a forked yellow beard.
 * Khal Drogo's appearance is slightly different to his description in the books. He is described as having long mustachios with rings in them and many bells in his long braid. In the series, he has a beard with a single ring in it and does not have bells in his hair.
 * In the books, Daenerys, Viserys and Illyrio attend a party at Khal Drogo's manse in Pentos to celebrate Drogo and Daenerys's engagement. The party is where Ser Jorah is first seen. In the series, Khal Drogo simply rides up to Illyrio's manse with his bloodriders to assess Daenerys.
 * Tyrion Lannister's appearance is different to his description in the books. He is described as having stunted legs, a swollen forehead, a squashed-in face and eyes of different colors. He walks with a profound waddle.
 * Tyrion's introduction in the books is different. He is introduced at the feast through the eyes of Jon Snow. In the TV series, he is introduced in a scene with the prostitute Ros after Robert Baratheon's arrival.
 * The prostitute Ros is not named in the book. She is probably the mentioned "red haired whore." In the TV series, she is a recurring character.
 * There's an additional conversation between Catelyn and Sansa, which introduces Sansa's character and her personality. In books she only briefly appears at the feast and her personality is introduced at the Trident.

 * Several scenes at the feast do not appear in the books: Jaime and Ned talk about tournaments; Sansa speaks to the queen and Arya throws food at Sansa.
 * ​When Maester Luwin comes with the letter about Jon Arryn's murder, into Eddard's bedroom, Catelyn is naked in the book. She even gets out of bed naked saying that it doesn't matter as Maester Luwin delivered all of her children. In the episode, she is dressed in a sleeping gown.
 * Lysa's letter isn't coded in TV series and came by a messenger. In the book it is coded, found in a box with a false bottom, and was left in Maester Luwin's room by an unknown party.
 * Daenerys and Khal Drogo's wedding scene is shown earlier in the TV series than in the book. Ser Jorah Mormont is introduced in this scene rather than in Daenerys' first scene.
 * Jorah Mormont's appearance is different to his description in the books. In the books, he is described as bald, stocky, hairy, and unattractive, but is strong and fit. In the series, he has short blond hair and is leaner and more attractive.
 * ​In the book, Catelyn Stark encourages Ned to accept King Robert's request. In series, she is afraid for him and begs him not to accept.
 * ​In the books Eddard plans to take Bran to King's Landing, before he is injured. There is no mention of this in the episode.

 * In the book Cersei stands with her back to a wall when Bran sees her from the window, while a man stands before her with his back to Bran and his hand between the legs of Cersei. In the series, Cersei is on her hands and knees while Jaime mounts her from behind. A body double is used for this scene.

 * In book, King Robert 's and Eddard 's conversation about Daenerys Targaryen takes place during the riding. In series, it takes place at breakfast. In the book scene, Jorah is revealed to the reader as an informer to the King's council. In the series, that is mentioned in Episode 5 at first.
 * In the series, Yoren doesn't appear in the scene with two rapists.

 * The saying about the Hand is changed as well. In the book, the saying is, "The King eats, the Hand takes the shit". In series, the saying is, "The King shits, and the Hand wipes".
 * Many recruits in the Night's Watch are omitted in the series such as Toad and Halder, and Dareon's character only makes a brief appearance. Parts of Dareon's dialog is given to Pyp's character . In the first scene at the Wall, there are three notable recruits: Grenn, Pyp and Rast. Rast also gets more screentime than in the book. There is also an unnamed recruit with long hair who often appears with Rast, who may possibly be Satin, but his name is never mentioned.
 * Grenn isn't called Aurochs, and Rast isn't called Rat in the series.
 * In the fight with Grenn, Jon breaks Grenn's nose instead of Grenn's wrist in the series. He is also shown fighting more recruits in series. (In book, he fights only Grenn).
 * The breakfast scene at King's Landing is extended in the series. Arya is stabbing the table, Eddard appears at the breakfast and gives Sansa a doll. Septa Mordane doesn't follow Arya into her bedroom.

 * In series, Theon Greyjoy comes for Bran instead of Maester Luwin.
 * An additional conversation between Tyrion Lannister and Theon Greyjoy. Theon's past and origins are revealed in this scene.
 * Castle Black is shown to have walls and a gate in the series. In the novels, it has none, so the Night's Watch can only defend against enemies coming from the North, and thus cannot rebel against the Seven Kingdoms.
 * Samwell Tarly's introduction is slightly different in the series because of omitted recruits of the Night's Watch. In the book, Sam is attacked by Halder first. When Jon defends him, Halder, Rast and Albett fight Jon, Grenn and Pyp. In series, Rast attacks Samwell. Jon then alone takes a fight against Rast, Grenn and Pyp.
 * In series, Sam isn't called Ser Piggy. Ser Alliser and Rast often call him Lady Piggy, which is even worse nickname. (In book, ser Alliser uses this nickname only when Jon defends Sam)
 * In the series, Sam tells Jon Snow about his father ordering him to join the Night's Watch. In the book, Samwell Tarly remembers the scene with his father skinning a deer. This scenario was used for the introduction of Tywin Lannister, when he is talking to Jaime about living up to his destiny.
 * There's an additional scene in Vaes Dothrak. Viserys and Doreah are having a bath. They talk about dragons and their skulls in Red Keep. In the book, it is only mentioned that Viserys and Doreah have had sex.
 * An additional conversation between Septa Mordane and Sansa about Sansa's future, Prince Joffrey, the Iron Throne and the deaths of Rickard and Brandon.

 * Gendry's character is aged up in the series. In books, he is 16 years old. In series, he must be over 20.
 * Another additional conversation between Jaime and Jory. Jaime is guarding the door, while the King is having group sex. Jory comes with the message for the king. He tries to give it to Jaime, but he refuses. Thoros of Myr is mentioned.
 * The Greyjoy Rebellion is revealed from their conversation.
 * Additional scene at the Wall after Jon's confrontation with Rast at night: The recruits don't dare to attack Sam because Jon has threatened them. Ser Alliser grows furious because of that.
 * Another additional scene at the Wall in which Jon reveals his story with prostitute (which is Ros in the series). Ser Alliser then comes and tries to frighten them with his story about the winter beyond the Wall, in the books Ser Alliser is not a ranger and doesn't go north of the Wall.
 * There's an additional conversation between Eddard and Queen Cersei.
 * The Tournament of the Hand is a lot shorter in the series. The only notable participants are Ser Gregor, Ser Hugh, Ser Loras and partly the Hound. The only shown fights are the jousts between Ser Hugh and Ser Gregor, Ser Gregor and Ser Loras, and the duel between the Hound and Ser Gregor. There is no mention made of the archery contest or the melee. In the books the jousting alone is over the course of two days.
 * In the series, Littlefinger tells Sansa the story about the Clegane brothers. In the book, the story is told by Sandor himself.
 * In the series, Arya attends the tournament. In the book, Jeyne Poole accompanies Sansa to the tournament, not Arya.

The Wolf and the Lion

 * In the series, Sandor Clegane isn't shown participating in the tourney, and he spends all the time near the King and Prince Joffrey. He only gets involved, when his brother is about to kill Ser Loras.
 * When Catelyn and Tyrion are ambushed by the hill clansmen on the way to the Vale, most of their party is killed. The only survivors are Catelyn, Tyrion, Ser Rodrik, Bronn, and Marillion. In the series, only a few of their party were killed by the clansmen. During the attack, Tyrion fights only with a shield. While in the book, he uses an axe.
 * More additional scenes at Winterfell: A conversation between Bran and Maester Luwin and a sex scene between Theon and Ros.
 * Arya doesn't confront Myrcella and Tommen when she is chasing cats in the series. In the book, they see her and set the guards to catch her, but she escapes before anyone recognizes her. It is in the process of the escape that she gets lost under the Red Keep and comes to overhear the conspritors, as well as finding the dragon skulls.
 * In the series, Arya finds only one dragon skull in Red Keep's dungeons (probably the skull of Balerion due to its size) instead of finding several (as in the book).
 * In the series, the dragon skulls are white. In the books, dragonbone is said to be black due to a high iron content.
 * The two men in the dungeons are clearly seen in the series (Varys and Illyrio). In books, they are not identified. (Ilyrio can be identified because of his visual description. Varys is much harder to identify because he probably wears a makeup - "scared face and stubble of dark beard". The easiest way to identify him is by his sentence - ...I must have gold and 50 birds...)
 * There is an additional conversation in Red Keep between Littlefinger and Varys. The spying on each other and Eddard Stark is reveled in this scene. The sexual habits of Lord Paxter are not discussed in the book.
 * In the book, Arya comes back to surface miles away from Red Keep. She is also covered in sewage and must bathe in a river before she can return to the Keep. In the series she leaves the dungeons via the tunnel beneath Aegon's Hill on which the Red Keep is located.
 * The meeting between Yoren and Eddard is extended in the series. After Eddard sends Arya out with Jory (Desmond in the book), an additional scene follows, where Yoren tells about Catelyn kidnapping Tyrion. In the book a scene is described where Eddard takes Yoren to court and asks if any noble will do honor to his House and volunteer to serve at the Wall; none volunteer.
 * The Eyrie's appearance is different in the series. In the books, it's a small traditional castle made of seven towers located on a shoulder of a very tall mountain - the Giant's Lance. The path is also guarded by three smaller towers. The castle in the series is located on the top of much smaller mountain and its path doesn't seem to be guarded by towers.
 * The guarded pass Bloody Gate, which is the main entrance to the Vale in books, also doesn't appear in series, neither do the characters of Brynden Tully and Donnel Waynwood, who are the guardians of the Bloody Gate. Their roles are given to Ser Vardis Egen in the series.
 * Catelyn's way from the foot of the mountain to the Eyrie isn't shown in series. She makes the climb riding on the back of a mule. Mya Stone, the bastard daughter of King Robert, whose job it is to escort people to the Eyrie, is absent in the series.
 * In the book, Catelyn first reaches the Eyrie alone and meets her sister in her chambers. Tyrion is then brought after her, being winched up the next day in a basket. In the series, Catelyn and Tyrion reach Eyrie together and both confront Lysa in the main hall in front of all important residents. There follows an additional scene, which shows Tyrion's imprisionent and briefly shows Mord.
 * Robert Arryn is renamed Robin Arryn in the series, probably to avoid confusion with King Robert Baratheon.
 * Lysa's appearance is different. She is shown as a very skinny woman in series instead of being overweight with pale and puffy face as in the book.
 * An additional scene in King's Landing involving Ser Loras and Lord Renly. This scene confirms that they are lovers, which is only hinted at in the books.
 * Another additional scene involving King Robert and Queen Cersei . It shows, that their marriage doesn't contain any love and it is the only thing holding the kingdom together. Lyanna Stark is also mentioned.


 * The scene in which Ser Jaime attacks Eddard is slightly different in the series. In the book, Jaime wants only to frighten Eddard and orders his men to attack Eddard's guards. Eddard then gets his leg crushed by his injured horse when it falls, as he tries to come to the rescue of his men. In the series, Jaime orders them to capture Eddard alive, and he personally kills Jory by stabbing him through the eye with a dagger. Then he and Eddard attack each other while the Lannister guards are watching. The fight ends when Eddard is stabbed in the leg by a Lannister guard.

A Golden Crown

 * An additional scene in Vaes Dothrak, in which Daenerys holds a heated dragon egg. When Irri grabs it, she gets her hands burned while Daenerys remains unharmed.
 * Another dream of three-eyed crow, which is the same as the one in the fourth episode, appears in the series.
 * When Bran falls into ambush while he is on the ride, there are four attackers shown in series: Stiv, Wallen, Osha, and an unnamed man. In books, there are six attackers - The previous four, another unnamed man and a short fat woman named Hali. The direwolves (Summer and Grey Wind ) don't get involved in the fight in the TV series. In the book the wolves arrive with Robb and kill several of the wildlings.
 * The series also shows one of Tyrion's failed attempts to get Mord's attention by offering gold. In the book, he convinces him by his first attempt and men come to Tyrion's cell to confirm his willingness to confesses, allowing him to get them to make Mord return Tyrion's shadowcat skin coat.
 * There is another additional scene in King's Landing showing another sword practice between Arya and Syrio and mentioning Syrio's series-only quote (There's only one thing we say to Death...NOT TODAY)
 * In book Eddard tells Arya who is angry that she will have to stop her lessons with Syrio Forel, if she is sent back to Winterfell, that Syrio may come with them if he chooses to enter Eddard's service. This is not mentioned in the episode. In both the fate of Syrio is uncertain.
 * Eating the stallion's heart seems to be the only part of the Vaes Dothrak's ceremony in series. In the books, there follows the procession around the sacred city.
 * The ceremony is also shown more from Ser Jorah's and Viserys's perspective in series rather than Daenerys's in the book. There also follows additional series scene in which Viserys tries to steal Daenerys's eggs. This scene is only briefly mentioned in the book.
 * Tyrion's confession of crimes is extended in the series. In the book, he is stopped immediately while in the series, he gives several funny examples.
 * An additional scene involving King Robert on his hunt, along with Renly, Barristan Selmy, and Lancel Lannister. He speaks of "good old times" and "making the eight". Lancel is clearly shown goading Robert into drinking strongwine. In the book the hunt is never seen, and Varys tells Lord Eddard about the overly strong wine that Cersei gave Lancel to give to Robert. The term "making the eight", never appears in the book.
 * In the books, there was no request of summoning Tywin Lannister to the court because of Ser Gregor 's attack.
 * In the book there is no scene between Ros and Theon, as she is leaving for King's Landing. Ros is possibly the unnamed, only mentioned red-haired prostitute, but no prostitute is mentioned leaving Winterfell much less talking to Theon about it.
 * There are several changes in Tyrion's trial by combat. In the series, it takes place in Eyrie's High Hall by the opened Moon Door, immediately after Tyrion's confession. In the book it takes place in the Eyrie garden, the next morning. The death of Ser Vardis is more dramatic in series. In the book, he is stabbed in the chest while he falls to the ground. In series, he is injured several times, stabbed in the neck and finally thrown through the Moon Door. Also, the brief conversation between Lysa and Catelyn before the trial isn't shown in the series.
 * In the series, the Moon Door is an opening in the floor of the Eyrie's High Hall. In the books, the Moon Door is a weirwood door that stands between two pillars in the Eyrie's High Hall.

You Win or You Die

 * The episode opens with a scene at the Lannister camp with Tywin and Jaime Lannister . Jaime and Tywin discuss family legacy while Tywin is seen cleaning a dead stag.
 * In the book, the scene where Eddard confronts Cersei about Jaime takes place in the Red Keep's godswood. The scene takes place in an outside courtyard in the series. Cersei also attempts to seduce Eddard in the book and slaps him when he spurns her advances.
 * There is an additional scene in Littlefinger's brothel where he talks about his past and coaches Ros and another prostitute, Armeca, who is exclusive to the series.
 * There is a scene at Winterfell between Theon Greyjoy and Osha. Maester Luwin comes in and asks Osha why the wildlings were south of the Wall.
 * There is also an additional scene at the Wall, which shows the return of Benjen Stark's horse without his rider. That makes whole Castle Black worried. In the books, the men of he Night Watch become worried only because of Benjen's long absence.
 * In series, Eddard is warned by lord Renly that something terrible has happened to Robert. In the books, he only suspects that because of dead silence on his way to king Robert.
 * Tomard, one of the guards at Winterfell, is sent to Dragonstone with a letter informing Stannis Baratheon that his brother has no rightful heirs, making him next in line to succession. In the books, Stannis had investigated with Jon Arryn and knew that Jaime was the father of Cersei's children.
 * Tomard's appearance is different from the book. He is nicknamed Fat Tom, but in the series, he is not shown to be particularly overweight. He is one of the many guards that Eddard Stark brought from Winterfell, but he has diminshed screentime in the series as Jory was more prominent.
 * In series, every recruit is passed out of training and becomes a man of the Night's Watch (ser Alliser mentioned that in episode 4). In books, ser Alliser passes on only 8 recruits (Jon, Halder, Grenn, Pyp, Toad, Matthar, Albett, Dareon). Sam was thought to remain recruit.
 * In the books, Jon Snow is worried that Sam might not be initiated with the other recruits. No such concern is shown in the series.
 * In books, Jon has to convince maester Aemon to pass Sam out of training because of his reading skills. In series, Sam automatically leaves training.
 * Pyp is named to the stewarts in series instead of being named to the rangers. Rast is named to the rangers, but in the books, he remains a recruit.
 * In series, maester Aemon gives orders to the new stewarts instead of Bowen Marsh in books.

The Pointy End

 * In the series, Septa Mordane tells Sansa to go and lock herself in their rooms, while she goes to confront the Lannister soldiers coming down the hall. In the book, Sansa and Septa Mordane are not together when the massacre occurs. As in the series, Sansa distraught with her father breaking her engagement and sending her back to Winterfell, went to Cersei to get her to talk to him and change his mind. This causes Cersei to accelerate her plans to prevent it. However, in the book, Cersei has the Kingsguard take Sansa to a tower room and imprison her there immediately afterwards, before the massacre takes place.
 * The soldiers that fight Syrio in the book are more lightly armored, and Syrio with a wooden sword does far greater damage to them, killing them with stabs through the neck and eyes. In the series he merely disarms and injures them.
 * There are several scenes showing the Lannisters' massacre of the Stark people: Vayon Poole is killed, Sansa gets captured by the Hound, Septa Mordane makes a stand... The book describes only the aftermath through Arya's eyes.
 * Arya's stableboy killing looks more like an accident in the TV series.
 * Sam has several more observations to make about the dead rangers in the books.
 * Jon killing the wight with the thrown lantern severely burns his arm. It heals painfully, and he is left with very bad scars. In the book Jon throws burning curtains over the wight.
 * The Lhazareen girl Eroeh who is first one Daenerys saves, and who then becomes devoted to her, is absent from the series. In the series, Daenerys is shown rescuing many women, primarily Mirri Maz Duur..
 * There is a duel in the series between Mago and Drogo, after Mago challenges Drogo's authority. Drogo slices open Mago's throat and rips his tongue out. Mago is actually still alive in the books. The duel was added to the series as Jason Momoa believed that the audience hadn't been shown Khal Drogo's combat prowess.
 * The wound that Mirri Mas Duur infects was worse than the one shown in the series which was superficial. In the book he is wounded in battle with the Lhazareen.
 * Ser Barristan, in the book, not only throws the sword at Joffrey's feet, but tells him that Joffrey will need it when Stannis arrives. After Ser Barristan leaves, Joffrey thinks that this was a treasonous threat and orders the Gold Cloaks to go after Selmy and kill him. Barristan must fight his way out of the city. In the series, he is simply allowed to leave.

Baelor

 * In the books, when Ser Barristan Selmy is dismissed from the Kingsguard he announces that he will search for the rightful heir. He later kills two members of the city watch when they attempt to detain him for questioning.
 * In the book, it is Elmar Frey to whom Arya becomes betrothed. While in the series, Arya is betrothed to Waldron Frey, a name which never appears in the books.
 * In King's Landing, Arya is seen in the series trying to trade the dead pigeon to the baker for bread. In the books, the baker has tarts, and Arya first asks for a lemon one. This is an interesting choice as lemon is often referred to as Sansa's favorite. When Arya was invited to have lemon cakes with the queen in her wheelhouse, she couldn't care less. Now she appreciates them.
 * Arya drops the pigeon when the crowd draws her to the Sept of Baelor for Lord Eddard's trial, in the series. In the book, Arya takes the pigeon with her to the docks, where she discovers that the boat her father had hired to take her back to Winterfell was still at the dock, with men dressed in Lord Eddard's colors. At the last minute she realizes that it is an trap. She loses the pigeon, which is on her belt, as she is running away, but, whether it fell or was stolen by a pickpocket, she is unsure.
 * In the books, Tyrion, Bronn, and Shae do not play the drinking game, and it is much later before Tyrion tells them each, separately, about Tysha.
 * In the books, Tyrion Lannister is depicted giving a battle speech, before riding in the vanguard and fighting a knight whom he eventually causes to yield. He is also described as wearing a mish mash of armour instead of his custom suit as shown on TV, because his armour is still at Casterly Rock. This causes the audience to miss him spearing a horse with a unicorn helm, the only thing they could find that fit his head. In the series, Tyrion is knocked out before the battle even starts by an errant warhammer and wakes up after everything is over.

Fire and Blood

 * In the series, it is Sandor Clegane who lifts Eddard's head instead of Janos Slynt.
 * In the books, Yoren tells Arya that the man (Varys) who brought Gendry to him was the same one who told him to delay leaving and be at the Sept of Baelor, because the trial of Eddard Stark was supposed to result in him being sentenced to take the black and he would be going with Yoren to the Wall.
 * In the series, Maester Luwin doesn't accompany Bran into the crypts below Winterfell; Osha takes him. In the book, it is Maester Luwin who takes Bran down to the crypts to show him that his father is not there, and Shaggydog bites him. Bran and Rickon then go with him back to his tower and are there when the raven arrives with word of their father's death (their wolves begin to howl and Rickon begins to cry before the raven comes).
 * An additional scene from A Clash of Kings, when Arya meets Gendry, Hot Pie, and Lommy Greenhands, is shown in the series.
 * Arya only threatens Hot Pie with Needle in the series. In the book, she beats him with a wooden sword and Yoren punishes her for that. This event also happens during their journey instead of on the streets of King's Landing.
 * Lommy doesn't use the nickname "Lumpyhead" for Arya in the TV series.
 * Rorge and Biter are seen, along with a hooded man who is presumably Jaqen H'ghar.
 * In the book, Sam does not ride out with Grenn and Pyp, after Jon who is deserting the Night's Watch, and he doesn't ride into a tree branch, knocking himself off of his horse. Sam tells the others, and seven recruits ride out to pursue Jon. Sam himself, a poor rider, remains in the barn back at Castle Black, waiting for them to return.
 * In the book, when Daenerys steps into the pyre, it all occurs in the same night. In the series, the scene ends the next morning.
 * The scene between Catelyn and the imprisoned Jaime is based on a similar scene between them in A Clash of Kings. This scene is broken into two parts. One half here and the other part is in season two, when she goes to see Jaime with Brienne of Tarth. The dialogue between the two here is only a small fraction of the whole conversation, and does not include Jaime's teasing comment about Bran: "I seldom fling children from towers to improve their health. Yes, I meant for him to die".
 * In the book, when Daenerys is found in the smoldering remains of the fire, the dragons are nursing mother's milk which she has as she was pregnant. Also, though her skin is unburnt, all off her hair has burned away.
