Differences between books and TV series - Season 3

Game of Thrones (Season 3) vs A Storm of Swords (book) Spoilers may follow.

Valar Dohaeris

 * Nearly the whole scene of the Battle of the Fist of the First Men is omitted.
 * Samwell Tarly is on the Fist of the First Men during the White Walker/wight attack. He did send out the ravens, but only two of them carried a message.
 * Ghost is not present during the battle, he's with Jon Snow.
 * Most of the remaining brothers of the Night's Watch were all on horseback after their escape.
 * In the books, Rast was never present at the Fist of the First Man as he remained a recruit and stayed at Castle Black.
 * The wildling spears are all tipped with metal points, while in the novels they're simple sharpened poles.
 * In the novels, giants wear no clothing, they are covered in shaggy fur pelts like mammoths. They are much more like descriptions of a Sasquatch or yeti.
 * In the novels, when Jon Snow enters Mance Rayder's tent, Mance is singing a song, which makes Jon think of him as a singer and not the King-Beyond-the-Wall.
 * Mance's wife Dalla and her sister Val were present when Jon encounters him in the novels.
 * Jon does not kneel before Tormund.
 * While Mance is glad Qhorin is dead, he is also sad since he was once his friend.
 * Mance Rayder tells Jon that he visited Winterfell as a singer during King Robert Baratheon's visit.
 * Jon gives a very different reason as to why he wants to join the Free Folk, involving his bastardy and upbringing in Winterfell.
 * Tywin Lannister visited Tyrion many times while he was unconscious.
 * Podrick Payne mentions that Bronn was anointed by the King himself. In the book, Bronn is anointed by a member of the Kingsguard.
 * The scene with Sansa Stark and Shae does not happen in the book.
 * Petyr "Littlefinger" Baelish never approached Sansa Stark directly with his offer of escape, but acted through an intermediary - Dontos Hollard. Sansa had no idea that Dontos works for Littlefinger.
 * Baelish never tells Sansa that Arya is alive, as he never visits Harrenhal to observe her as Tywin's cup bearer.
 * It isn't clear if Littlefinger is simply meant to be lying, and never recognized Arya at Harrenhal. Particularly given that Littlefinger doesn't know that Arya escaped Harrenhal, and moreover, that Harrenhal falls to the Starks in this episode, it wouldn't make sense for Littlefinger to realize that Arya was at Harrenhal but do nothing to let her fall out of his control. Compare that he earlier lied to Catelyn about having both Sansa and Arya in King's Landing.
 * The scene between Tyrion and Cersei Lannister in Tyrion's chambers does not happen in the book.
 * The scene where Margaery Tyrell comforts the orphans and hands out food does not happen in the book, though is loosely hinted at as it is reported to Tyrion that Margaery is deftly building up support for herself among the commoners by handing out food aid.
 * The dinner scene with the Tyrells and Lannisters does not happen in the book.
 * Davos Seaworth was stranded on a tall spire of rock, not a conical island.
 * It is not made clear how long Davos was stranded in the series, while in the book he is there for about a fortnight.
 * While Davos is on the island, he has a dream about the Mother, chiding him for watching how Melisandre and her followers destroyed the idols of the Seven in Dragonstone and the Godswood in Storm's End, while doing nothing to stop the blasphemy. Since Davos was in high fever, undernourished and overwhelmed with grief for the loss of four of his sons, the dream could be hallucination. The whole scene is omitted from the series.
 * Davos was rescued by one of Salladhor Saan's captains, not Saan himself.
 * Davos was not taken to see Stannis Baratheon for months as he was thrown in the dungeon almost the moment he set foot on Dragonstone. Melisandre found out about Davos' plan to kill her.
 * In the books it was Lord Bryce Caron, Lord of Nightsong and one of Stannis' most powerful bannerman, who convinced Stannis not to bring Melisandre to the Blackwater, not Davos. In the books Lord Caron was killed during the Battle of the Blackwater.
 * There was never a massacre at Harrenhal.
 * Neither Catelyn nor Robb Stark went to Harrenhal.
 * Qyburn was therefore never encountered at Harrenhal having survived a massacre, nor was he affiliated with Robb's army.
 * By this time in the books, Harrenhal was already taken by Roose Bolton.
 * The conversation between Rickard Karstark and Roose Bolton never happened in the books.
 * Daenerys is seen traveling with only one ship in TV series. In books she travels with three ships named "Vhagar", "Meraxes" and "Balerion", named after the Aegon the Conqueror and his three sisters' dragons.
 * The ships were sent by Illyrio Mopatis in the books. In the series, she bought one ship after she had looted Xaro's mansion in Qarth.
 * Ser Barristan Selmy does not reveal his identity until much later in the book; he is under the alias of Arstan Whitebeard and is sent by Illyrio.
 * Ser Barristan is squire for Strong Belwas in the books, while this character does not exist in the series.
 * Astapor is constructed of crumbling red bricks in the novels.
 * Daenerys first plans to go to Pentos, but takes a detour to Astapor on Ser Jorah Mormont's insistence.
 * Missandei is also much younger than she is presented in the TV series. She is around 10 at this time.
 * Ser Barristan's white hair and beard were grown long as part of his disguise, but not in the series.
 * The Unsullied training also includes the recruits raising a puppy for a year before strangling it to death. Also unmentioned is that during their training the Unsullied are given a potion to drink known as the Wine of Courage, which gradually deadens their bodies' sensitivity to pain. In the books, it is stated that only one in three boys survive the years of training to become Unsullied, while the TV series says that only one in four boys survives.
 * The assassination attempt on Daenerys Targaryen is made back in Qarth, before she leaves for Astapor. It is also sent by the warlocks, but it is through a ​Qartheen guild of assassins known as the Sorrowful Men.

Dark Wings, Dark Words

 * Jojen and Meera Reed are introduced much earlier in the books; they come as guests during one of the harvest feasts at Winterfell.
 * Jojen Reed is much younger in the books.
 * Bran dreams of a three-eyed crow, not a raven.
 * Osha, Rickon and Shaggydog  had split up from Bran, Hodor, Summer, and the Reeds beforehand in the book. The TV producers said they pushed the Reeds back into Season 3 because there wasn't enough time to fit them into Season 2 without overfilling the season with too many characters.
 * In the books, Catelyn was at Riverrun at her father's  bedside long before he died since the first book Game of Thrones, until his death in A Storm of Swords.
 * Lord Karstark never expresses any thoughts about losing the war in the book.
 * Neither Robb nor Catelyn had any hope that Bran and Rickon might be still alive.
 * Catelyn's tale about cursing Jon Snow with pox is never mentioned in the book.
 * The scene where Joffrey insults Cersei does not happen in the books.
 * Shae becomes Sansa's maid much later, and they are never on such amicable terms.
 * Loras is considerably upset when he meets Sansa in the books, as she reminds him of more innocent times at the Tourney of the Hand. In the books, Loras recklessly killed Renly's two Kingsguard members Robar Royce and Emmon Cuy, who were outside his tent when he was assassinated, out of sheer rage. Sansa mentions that she saw him defeat Robar Royce in the joust. Loras explains that he has killed Royce as well as Cuy, and becomes quite distraught because he is remorseful for his past actions.
 * At the dinner Sansa is invited to, in addition to Olenna and Margaery, shemeets Margaery's mother Alerie Tyrell, her distant cousins Megga, Alla and Elinor, and more of the Tyrells' retinue: Janna Fossoway, Leonette Tyrell, Septa Nysterica, Alyce Graceford, Alysanne Bulwer, Meredyth Crane, Taena Merryweather and the jester Butterbumps.
 * Sansa's description of Joffrey to Olenna Tyrell is actually much longer in the books. As in the series, it becomes increasingly clear that Sansa is worried that they will be overheard by the ever-present spies around the Red Keep. Therefore, Olenna bids her jester Butterbumps to sing The Bear and the Maiden Fair until he is bellowing it out at the top of his lungs. While the exact conversation is not presented in the text, Sansa describes in explicit detail all of the atrocities that Joffrey has committed since becoming king and long before that - lying about Mycah, causing her father to kill Lady, ludicrously ordering a dozen guards to kill a crowd of starving peasants numbering in the hundreds, shooting refugees with a crossbow simply for begging for bread at the castle gates, having her stripped and beaten in front of the entire court, etc. This did not seem to concern Olenna and Margaery, who apparently have already known what monster Joffrey is, and what Sansa told them only confirmed that.
 * Shae does not come to visit Tyrion until much later in the books, and even then they meet in the cellars at the dragon skulls.
 * Shae never expressed any concern about Sansa.
 * The crossbow scene with Joffrey and Margaery doesn't happen in the books.
 * Renly's homosexuality was only implied in the books, though George R.R. Martin has independently confirmed that he intended Renly and Loras to be lovers. Cersei's private disgust with Renly as a "degenerate" does not correspond to a scene from the novels at this point, though she does make similar comments to this effect disparaging Loras' homosexuality at other points in the book.
 * In the books the wildlings only speak the Old Tongue, though a few speak the Common Tongue (archaic English), not 7 different languages.​
 * The character Orell appears in this episode, but in A Clash Of Kings, he and Ygritte were part of two of the three watchers that Qhorin's party slew, but part of his spirit remained in his eagle. Technically Orell should not appear in the third season; he lives on by warging in his eagle. The TV character "Orell" is more of a splice with another warg character, Varamyr Sixskins.
 * A character called Small Paul, steward of the Night's Watch, carries Sam on his back in the book; Rast is not even on the beyond the Wall expedition.
 * Sam, Grenn and Paul fall behind the survivors of the Watch and encounter one of the Others. Paul is slain but Sam manages to kill the monster by accident, discovering their vulnerability to dragonglass (obsidian) in the process. The entire scene is omitted from the series.
 * The Night's Watch was retreating through the Haunted Forest in the novel.
 * Arya, Hot Pie and Gendry were all on horseback and were headed for Riverrun using a map Arya stole.
 * Arya came across the outlaws on a road near a river, not the forest.
 * The singer Arya hears wasn't Thoros, but a man named Tom of Sevenstreams, who was singing about a maid of Gulltown, not Rains of Castamere.
 * Arya scarcely recognized Thoros from his days at King's Landing in the books.
 * Thoros wasn't with the outlaws who found Arya. He is described as wearing faded red, almost pink, robes. Being from Myr, he also has a foreign accent.
 * The events surrounding Theon's imprisonment are not mentioned in the novels until the fifth book, A Dance with Dragons. The reader was left wondering if Theon had survived the Battle of Winterfell, though it is mentioned by Lord Bolton that he is being flayed at The Dreadfort.
 * Sandor Clegane does not appear until much later in the book. He does not reveal Arya's true identity to the Brotherhood. In fact he does not even recognize her at first, even when she openly accuses him of Mycah's death, only after taking a good look at her. Several members of the Brotherhood are actually the last remnant of her father Eddard's personal guard that he sent out to bring Gregor Clegane to justice, and one of them, Harwin, recognizes Arya instantly. Harwin was actually present when the newborn direwolf pups were found in the first regular chapter of the series (after the first Prologue scene).
 * The people that find Jaime Lannister and Brienne of Tarth are the notorious sellsword company Brave Companions (who do not exist in the series), not Bolton's men​. There was no farmer who told them where to find Jaime and Brienne. The noise Jaime and Brienne made while fighting attracted the attention of the Brave Companions. They also fought for a long time before being found, and ended in a river where Jaime slipped and fell.
 * Cleos Frey (who was replaced by Alton Lannister in the series) is with Jaime and Brienne in the book. Shortly before the encounter with the Brave Companions, they were attacked by archer outlaws who killed Cleos and injured Brienne. It's Cleos' sword that Jaime took when he dueled Brienne. Brienne was injured by two arrows before she fought Jaime. Both managed to injure each other, but Brienne overcame Jaime.

Walk of Punishment

 * Brynden Tully isn't upset with his nephew for missing his father Hoster Tully's funeral boat with his flaming arrow. The book makes it explicit that Edmure misses because he is so consumed by grief at his father's death that he cannot shoot straight. Brynden later tells Catelyn that Hoster himself, at the funeral of Hoster and Brynden's father, was so consumed by grief that he also missed his father's funeral boat.
 * Brynden Tully calls himself "the Blackfish" because of his rocky relationship with his older brother, stemming from Brynden's refusal to take part in a marriage-alliance to House Redwyne which Hoster proposed for him. This led to Hoster calling him the black sheep of the Tully family, but pointing out that the Tully symbol is a fish, Brynden decided that this made him the "Black-fish" of the Tully family. Brynden took as his personal sigil the normal blue and red Tully heraldry, but with the silver fish replaced with a black one.
 * Edmure had been enraged that Walder Frey had sent "a cripple and a bastard" (Lothar Frey and Walder Rivers) to the funeral, but Robb had greeted them with courtesy and gives Lothar Frey a spot as pallbearer.
 * Edmure's blunder is actually dealing Lord Tywin a loss at the Fords which allowed him to learn of Stannis Baratheon's attack on King's Landing and he turned his army south in time to take Stannis's army in the rear. The victory by Ser Edmure destroyed Robb Stark's plans of forcing Tywin to return to the west and penning him within his own lands
 * Willem and Martyn Lannister are not distant relatives of Tywin, but his nephews. They were not captured by Edmure Tully in the Battle of Stone Mill, but by the Starks long before: Willem and his cousin Tion Frey (son of Genna Lannister and Emmon Frey) were captured in the Battle of the Whispering Wood, while Martyn was captured in the Battle of Oxcross. However, it isn't clear if Robb was simply being sarcastic to make dramatic emphasis that if Tywin didn't stop when his own eldest son was prisoner, he won't stop when his more distant relatives are prisoners either. In Kissed by Fire, Edmure says they are Tywin's nephews.
 * ​Podrick does not get a reward for serving Tyrion Lannister's in the book. Particularly, he is not rewarded with prostitutes: Podrick is much younger in the books, only about 12 or 13 years old, but was aged-up for the TV series.
 * Tormund and Orell are not among the Wildlings that Mance Rayder sends to scale the Wall.
 * Also in the books, Mance sent 120 men to scale the Wall, led by Styr the Magnar of the Thenn. In TV series he sent only 20.
 * The specific scenes with Tyrion, Littlefinger, Ros, Bronn, and Pod at the brothel do not happen in the books, though after Tyrion is made Master of Coin he comments on discrepancies in how Baelish has been running things. It is not mentioned that Littlefinger has increased the crown's incomes tenfold since coming into office.
 * The literal "game of thrones" that Tywin Lannister plays with the Small Council does not occur in the books. However, it is an accurate assessment of the disposition of these characters: Baelish is zealously ambitious, Varys is content to let Littlefinger think he has the upper hand, and Pycelle  has survived numerous regime changes in King's Landing by not actively competing with the other advisors. Cersei  is determined to be at her father's right hand even when he doesn't provide her with a position to be so. Tyrion, meanwhile, actively disdains trying to win his father's favor at all, and mocks the others by going out of his way not to.
 * After Pycelle was released from prison, he resembles a shambling skeleton, leaning heavily on a twisted cane and shaking as he walks, a few white hairs sprouting from his long neck in place of his once-luxuriant white beard. In the series, the only visible change about him is that his beard is shorter than before being imprisoned.
 * Tywin's Small Council has more members in the books. Mace Tyrell, his bannermen Matthis Rowan and Paxter Redwyne, Kevan Lannister, and the High Septon are all present at the first council meeting.
 * Arya Stark and the Brotherhood Without Banners do not stop at the Inn at the Crossroads, but a different inn further southwest known as the Inn of the Kneeling Man. The irony is that last episode, Arya made a big point stressing that the Red Fork of the Trident River is a hundred feet wide and difficult to cross... yet in order to reach the Inn at the Crossroads from Harrenhal, they would have to have crossed the Trident "off-screen" during the middle of the previous episode (as they are already having a meal at the inn by the end of the episode). In the books, the Inn of the Kneeling Man is south of the Red Fork, between Harrenhal and Riverrun.
 * Hot Pie therefore stays at the Inn of the Kneeling Man in the books, not at the Inn at the Crossroads.
 * The innkeeper of the Inn at the Crossroads, Masha Heddle, was killed at the end of the first novel, when the Lannister armies overrun the Riverlands. Tywin has her hanged from a gibbet for allowing Catelyn Stark to kidnap his son. Tyrion himself is upset at this, as Masha was just an innocent bystander and didn't have any choice whether Catelyn took him prisoner or not. The inn is subsequently run by Masha's nephew. Masha's death hasn't been explicitly established in the TV series. In this TV episode, Hot Pie says that "the innkeeper" was impressed by his baking skills, but this doesn't necessarily mean that Masha is still alive in the TV continuity, as Hot Pie doesn't state what the specific name of "the innkeeper" is.
 * Melisandre leaving Dragonstone to search for "a king's blood" is a heavy condensation of Stannis Baratheon's storyline in the third novel. In the books, his brother King Robert does have one acknowledged bastard son, Edric Storm, who was raised at Storm's End. In the second novel, after Renly is assassinated outside of Storm's End by a shadow-creature, Cortnay Penrose the castellan holds out against Stannis and refuses to hand over Edric, so Melisandre has to make another shadow-creature to assassinate him as well. Subsequently Stannis takes control of Storm's End, and takes Edric Storm back to Dragonstone for safe keeping. After Stannis' crippling defeat at the Battle of the Blackwater, Melisandre urges that she must make a blood sacrifice by burning Edric alive as an offering to the Lord of Light. Much of the Dragonstone subplot in the third novel revolves around whether or not Stannis will go through with sacrificing Edric Storm.
 * Samwell Tarly doesn't see the birth of Gilly's baby in the book.
 * The events surrounding Theon's escape are not mentioned in the novels until the fifth book, A Dance with Dragons.
 * Locke (analogous to Vargo Hoat) never participated in Brienne's attempted rape as Jamie already informed him about Tarth's sapphires, and forbade his men to harm her.
 * Vargo Hoat does not personally maim Jaime in the book. Vargo gives the order, but one of his subordinates in the Brave Companions, a fat Dothraki named Zollo, carries out the deed.
 * When Daenerys walks through the streets of Astapor  and comes to the Plaza of Punishment, she sees a wooden platform where rebellious slaves are racked, flayed and hanged, but she does not try to help any of them.
 * ​Ser Barristan is still under the guise of Arstan Whitebeard, a masquerade he puts up to get to know Daenerys. He is also accompanied by the omitted character, Strong Belwas, who he squires for.

And Now His Watch is Ended

 * After having his hand cut off, Jaime rode on the same horse as Brienne, at first tied back-to-back, then face-to-face as part of the abusing he suffered from his captors.
 * On the way to Harrenhal, three of the Brave Companions (Rorge, Shagwell and Zollo) sneaked at night to where Brienne slept, intending to rape her although Vargo Hoat forbade them because he believed Jaime's lie about sapphires. Again, Jaime intervened in time to save Brienne from gang-rape: he yelled "sapphires" loudly enough for Hoat to hear him. The three thugs beat Jaime severely till he lost conscious, but his yell did the trick: Hoat came and stopped his men. Since then, Hoat put guards to make sure no one harms Brienne. Brienne thanked Jaime for his help.
 * Varys told Tyrion the tale of how he was castrated before the Battle of the Blackwater, while they were discussing the strange circumstances of Cortnay Penrose's death. In both versions Varys explained that he traveled around in several of the Free Cities before being castrated in Myr, but in the books, he also adds the detail that he was born in Lys.
 * Varys never captures the sorcerer who cut him in the books.
 * Varys' scene with Ros does not exist in the books; Ros is an invented character for the TV series, but even in the books no character spys on Littlefinger for Varys this way. In the books, no one else is aware of Littlefinger's plot to sneak Sansa out of the city.
 * The scene with the Lannisters and the Tyrells in the Great Sept doesn't happen in the books.
 * It is not Joffrey but Stannis who mentions Aerion Targaryen. In fact, Aerion was the older brother of Maester Aemon.
 * It's somewhat ironic that Joffrey mocks Aerion, given that Aerion's personality was actually quite similar to Joffrey's: mentally unbalanced, pointlessly sadistic, cruel to animals, and terrorizing his younger siblings.
 * Joffrey wants to show Margaery the tombs of the last Targaryens (presumably the Mad King Aerys II, his son Rhaegar, and Rhaegar's children Aegon and Rhaenys), and that Robert Baratheon wanted them burned and scattered in the Blackwater River, but the High Septon convinced him to give them a proper funeral. In the books, the Targaryens were very proud of their descent from the Old Valyrian Freehold, and maintained the Valyrian custom of cremating their dead. Thus there are no tombs containing the corpses of past generations of the Targaryen dynasty. Even Rhaegar Targaryen was cremated after he died at the Battle of the Trident. Rhaegar was a man who Robert Baratheon utterly hated and even fantasized about killing again even years after he died, but even Robert still gave Rhaegar a proper funeral (when Rhaegar's soldiers who surrendered at the Trident insisted on it), cremating his body according to the customs of Rhaegar's family. Robert never had to be talked out of throwing their remains into the Blackwater river by the High Septon.
 * That being said, the books never specify what exactly the Targaryens did with the resulting ashes: they might have scattered them, but it is entirely possible that they interred urns containing the ashes (i.e. in a columbarium within the Great Sept of Baelor). Joffrey does state in the episode that Aerion Brightflame's ashes are kept in an urn, but of course, Aerion was burned from the inside out when he consumed wildfire. Joffrey's line still seems to imply that burning the last Targaryens would have been an insult; but his line might plausibly be interpreted as that scattering the ashes (instead of interring them) is what would have been offensive.
 * The books don't give explicitly detailed descriptions of what the Seven look like, other than basic details such as that the Father carries a set of scales, the Crone carries a lantern, etc. Being a visual medium, the TV series of course has to make fully realized artwork depicting the Seven. This episode shows the interior of the Great Sept of Baelor for the first time, and the statues of the Seven in the main sanctum are depicted as Greco-Roman or Renaissance artistic nudes, i.e. the Father looks like a Classical statue of Zeus, with a flowing robe that does not conceal his nudity. The Faith of the Seven is meant to be a loose analogue of the medieval Catholic Church, which was quite conservative and frowned upon such artistic depictions of nudity (albeit Jesus was frequently depicted as naked or nearly so on the cross, etc.) Then again, the Art History of the Seven Kingdoms doesn't need to necessarily correspond to social currents in real life, and such artistic depictions of nudity and religious figures were common in the Renaissance, i.e. the Sistine Chapel.
 * The scene where​ Cersei Lannister discusses Jaime and the Tyrells with Tywin never happens in the books.
 * Varys does not discuss Sansa Stark with Olenna Tyrell in the books. In fact, Varys takes no particular interest in Sansa in the novels and the plot to have her marry a Tyrell is Olenna's alone.
 * The scene where Margaery Tyrell and Sansa walk along the coast never happens in the books.
 * There is no character named Allana in the books, either of House Tyrell or otherwise.
 * The Tyrells planned to marry Sansa to Willas Tyrell, who is Lord Mace Tyrell's eldest son and heir, not to Loras, who by this point in the books has become a Kingsguard and cannot marry.
 * Theon Greyjoy never openly stated that he considered Eddard Stark to be his real father in the books, nor did he ever admit to anyone that the boys he killed and tarred were not Bran and Rickon.
 * It is not Rast but Dirk who tells Craster "So you admit you got a secret larder. How else to make it through a winter?".
 * Craster has his throat slit by Dirk in the novels, while in the TV series, a dagger is thrust into his throat by Karl, up into the roof of his mouth.
 * Lord Commander Jeor Mormont is stabbed in the gut in the books, not by Rast (who was not there but remained back at Castle Black) but by Ollo Lophand. Mormont does not manage to fight his murderer.
 * Before dying, Mormont told Samwell Tarly to go to the Wall, and to tell them "All. The Fist. The wildlings. Dragonglass. This. All. Tell my son. Jorah. Tell him, take the black. My wish. Dying wish. Tell Jorah. Forgive him. My son. Please. Go".
 * Sam stays back in the books, holding Lord Commander Mormont as he lays dying. Mormont commands him to escape with the others but he doesn't. Then two of Craster's old wives convince him to take Gilly and the babe and leave.
 * Sam and Gilly escape on horseback in the books (the Night's Watch still had some of its own horses when it arrived at Craster's Keep).
 * The Unsullied respond to Daenerys Targaryen' offer of freedom by shouting "Dracarys!" in the novels.
 * Daenerys swings the slaver's whip in Kraznys mo Nakloz' face and then releases Drogon on him with the command "Dracarys".
 * Daenerys offers her ships along with Drogon to buy Unsullied.
 * Missandei is already aware that Daenerys can speak Low Valyrian.
 * Daenerys orders the Unsullied to harm no child under twelve. In the TV series, she wasn't so specific, and just said "harm no child".
 * Daenerys' followers are aware of her plans beforehand and attack the slavers as soon as signaled (when she shouts "Dracarys" and the dragons begin to attack).

Kissed by Fire

 * It is Styr, the Magnar of Thenn, who questions Jon about the number of Sworn Brothers who remained at the three manned castles of the Night's Watch (not only in Castle Black). Jon's answer is "500 at Castle Black. 200 at Shadow Tower, perhaps 300 at Eastwatch". That was a deliberate lie. The actual number of the brothers who remained at the castles was no more than 700: 400 at Castle Black, 100 at Shadow Tower, less than 200 at Eastwatch.
 * In the series, Ygritte refers to the Lord of Bones as Rattleshirt. In the books, only the Night's Watch brothers call him by that nickname for mockery, not the wildlings.
 * Ygritte didn't take Jon's sword to lure him into the caves. The wildlings were camped in the caves for the night.
 * The chamber where Jon and Ygritte were was pitch black, with only their torch for light.
 * The first time Jon and Ygritte made love was in the middle of the other wildlings, under their sleepings furs at night.
 * Ygritte never mentions the second man she slept with, only her first.
 * It was not Gendry but Lem that stopped Arya  from attacking the Hound.
 * Arya told the Hound "You go to hell!". Beric said "He has", either referring to the event Gregor Clegane shoved Sandor's head into a brazier, or speaking metaphorically about the Hound's life.
 * Arya first learned of Gendry's intent to join the Brotherhood when he asked to be knighted by Lord Beric.
 * Melisandre had been interested in another one of King Robert's bastards being kept on Dragonstone called Edric Storm. However, Edric's character and storyline have been replaced with Gendry's.
 * Gendry is not taken by Melisandre, nor does she ever meet the Brotherhood Without Banners.
 * Lord Karstark is brought before Robb in front of a full court in the novel.
 * Rickard Karstark killed Willem Lannister and his cousin Tion Frey (son of Genna Lannister and Emmon Frey), not Martyn Lannister.
 * Catelyn and Robb's wife (Jeyne Westerling in the book) did not try to persuade Robb to spare Rickard, only Edmure  tried to.
 * Robb does not use his sword to behead Rickard Karstark in the novel. He uses an axe, and takes several swings to take his head completely.
 * In the books ​eight men killed the Lannister prisoners, only two died and one was too wounded to move.
 * It was Greatjon Umber, not the Blackfish, who punched Karstark for calling Robb "boy".
 * Karstark's forces did not account for half of Robb's army in the novels. Indeed, it is kind of absurd to insist that one noble House makes up almost half of the entire North's army. This might be explained away by Robb meaning that it was almost half of his current garrison at Riverrun itself. In the books, the Karstarks have around 2,300 men. Robb brought twenty thousand Northerners south, and they were joined by a perhaps equal number of soldiers raised by the Riverlords. They have been taking some losses in the war, and Robb has divided his forces between Riverrun in the west and Harrenhal  in the east.
 * Some of the Karstark soldiers have already left the garrison at Riverrun after the massacre of the Lannister prisoners.
 * Robb's plan was not to attack Casterly Rock in the books, it was to re-take the North from the Ironborn. At this point, Robb had returned to Riverrun from his campaign harrying the Westerlands. Casterly Rock and Lannisport were left with only a skeleton force of defense, but even so, Robb was reluctant to attack its solid defenses with the few men he had, particularly given that he had to divide his forces when the Greyjoys  attacked the North. The TV series presents this as a last-ditch effort spurred by the defeat of Stannis by the Lannisters and the loss of the Karstarks. Robb's plan in the books was indeed to return to the North, to drive the Greyjoys out and rebuild his power base from a more defensible location. There was some concern that soldiers would abandon the fight to gather harvests for winter, but the reasoning was that they'd at least still defend the North itself if the Lannisters tried to advance through the Neck. Thus, in the books, Robb doesn't just need the Freys' soldiers, he physically needs to cross back over the Twins to retake the west coast of the North from the Ironborn.
 * The Freys had already pledged their forces to support Robb, but left his side soon after he broke their marriage pact. This apparently occurred "off screen" at some point before Episode 2 of Season 3, "Walk of Punishment", when Robb's marriage to Talisa is presented as public knowledge (Bolton  and Karstark refer to her as Robb's wife). In the books, the loss of the Frey alliance is treated as a major disaster, costing them some four thousand badly needed troops. The TV series treated it like Robb wasn't particularly concerned, even though it was arguably worse than losing the Karstarks, given that the Freys have more men and control a vital strategic passage into and out of the North.
 * The TV series presents no practical argument for why Lord Karstark must be executed, making it appear to be an even worse mistake. In the books, it's pointed out that Robb has to kill Karstark to atone for the two Lannister prisoners he murdered, otherwise the Lannisters may respond by executing Sansa or other Northern prisoners in retaliation; that, and Robb needs to maintain basic discipline in his command, and can't let such direct treason go unpunished otherwise he will look weak. Then again, the TV series already built up Catelyn's release of Jaime Lannister to be far worse than it was in the books, in which after being told that Bran  and Rickon  died at Winterfell, Catelyn fears (not unjustifiably) that Joffrey  might kill Sansa simply on a whim, despite the fact that they hold his "uncle" hostage, so the only safe option is to get her daughters out of harm's way as soon as possible. Both decisions did have practical underlying reasons in the books, not pure emotion or ideology, so presenting Robb's decision to execute Karstark as having no practical merits sort of evens out for how much worse Catelyn's decision has been presented. In the books, Robb also has sex with then marries Jeyne/Talisa out of grief when he hears that Bran and Rickon are dead, so neither Catelyn or Robb feel they can justifiably be angry at the other, because they both made brash mistakes.
 * Beric's second death was caused by a smash in the head with a mace by Ser Burton Crakehall.
 * He wasn't hit with an axe, nor was he hung and stabbed in the eye at the same time. Those were two separate deaths. It may have been too difficult to portray the actor with a caved-in skull using practical effects.
 * Selyse is often by Stannis' side in the books.
 * Stannis never apologized to Selyse about anything. The books are ambiguous about if Stannis is consciously aware that Melisandre had sex with him to create a Shadow-creature, or if due to the magical powers involved, he didn't clearly remember what happened.
 * It is uncertain whether Selyse found out that Stannis was sleeping with Melisandre, and if she cared.
 * Selyse did not keep her stillborn children in jars in the novels. In fact it is never mentioned in the novels that she ever gave birth to stillborns, nor to any liveborn except Shireen. She mentions "Edric" as the name of one of her stillborns. Edric Storm is a bastard-son of Stannis' brother Robert, who was kept on Dragonstone for safekeeping in the novels, but who was removed from the TV series; Edric is actually a fairly common name in the Stormlands.
 * The song Shireen sings in the show, and is also played during the ending credits, was sung by her fool Patchface in the prologue of "A Clash of Kings". The line about the merwives amused Shireen, but she was scared of the line "The shadows come to dance".
 * Stannis never told Shireen that Davos was a traitor in the novels, nor did Davos ever give her a toy ship. In fact, Stannis never has any conversation with his daughter throughout the books.
 * Shireen never visits Davos in the books, nor does she attempt to teach him how to read. Maester Pylos is the one who offered Davos to teach him, much later. Melisandre is the only visitor Davos has while he is imprisoned.
 * Jaime's story about killing Aerys is given in the novel in two parts:
 * During the journey with Brienne and Cleos Frey, Jaime muses how he approached Aerys, who had sent him earlier to kill Tywin . Aerys asks if the blood on Jaime's sword is Tywin's. Jaime answers "Rossart's". Too late Aerys realized that Jaime turned against him. He lost control of his bowels, tried to run for the throne, but Jaime caught him and stabbed him in the back. Before Jaime could leave and let some braggart take the credit/blame, Elys Westerling and Lord Roland Crakehall entered and saw him standing over Aerys' body. Crakehall was not surprised, figuring (incorrectly) that Jaime killed the king so the Lannisters can seize the throne. He asked Jaime "Shall I proclaim a new king as well?". Jaime knew what he meant: either Tywin, or Robert Baratheon, or one of the surviving Targaryens. He thought for a moment of the boy Viserys or baby Aegon. But when he glanced down again at Aerys' body, he thought "his blood is in both of them". "Proclaim who you bloody well like," he told Crakehall. Then he climbed the Iron Throne and seated himself with his sword across his knees, to see who would come to claim the kingdom. As it happened, it had been Eddard Stark.
 * Jaime tells Brienne when they are in the bathtub about Aerys' plan to destroy the city. This part is quite similar to their conversation in the show.
 * Jaime stabs Aerys in the back; he does not slit his throat.
 * Jaime did not kill Rossart in front of Aerys in the books, nor was he present when Aerys gave the command to ignite the wildfire caches; in the books, Jaime was fighting to defend the Red Keep, but he knew the battle was lost. He sent a messenger to ask Aerys's leave to ask for terms of surrender; Aerys sent back the reply that Jaime bring him Tywin's head to prove his loyalty. When the messenger mentioned the pyromancer  Rossart was with the king, Jaime guessed they were about to go through with their plan, and went to stop them. He killed Rossart trying to sneak out of the Red Keep to enact Aerys' orders.
 * There were three pyromancers involved in Aerys' plot to raze King's Landing, not one as the TV series implies. Jaime slew Rossart during the Sack along with Aerys, and then hunted down and killed the other two (Belis and Garigus) in the days following the battle, to ensure all those who know of and could enact the plan were dead.
 * Eddard Stark was not the first to find Jaime after killing Aerys. Elys Westerling and Roland Crakehall were the first to enter the throne room and see Jaime standing over the Mad King's body.
 * Ser Barristan Selmy did sit on the Small Council in the books; he was present at the meeting where Daenerys's assassination was discussed, heard Jorah Mormont was the source of the information and was the only one besides Eddard Stark to protest the decision.
 * Ser Barristan and Jorah Mormont never befriended each other while serving under Daenerys because he is still disguised as Arstan Whitebeard.
 * In the series, the Unsullied are given new names after being castrated. In the books, they draw new names every day.
 * The scene where Cersei asks Littlefinger to investigate the Tyrells never happens in the novels.
 * The scene where Tyrion discusses the wedding with Olenna never happens in the book.
 * Littlefinger never sent Olyvar (or anyone else) to Loras in the books. The only book character by that name is Olyvar Frey, son of Walder Frey, who served as Robb's squire and proved to be very loyal. He never had anything to do with the Tyrells or Littlefinger.
 * At this point in the books, Loras swears that he will never love again after Renly's death. Of course, having sex with Olyvar in the TV series wasn't presented as a new "romantic relationship".
 * Loras was not the heir of Highgarden in the books, his elder brother Willas was. In fact, he had two older brothers, Willas and Garlan.
 * Loras cannot marry since he is already serving in the Kingsguard.
 * The Lannisters discovered Olenna's plan to marry Sansa to Willas by Dontos Hollard; Sansa innocently told him about the Tyrells' offer, unaware that he serves Littlefinger.
 * Since Tyrion did not like the idea of marrying Sansa, Tywin said that if he didn't have her, she would be wed to Lancel or another of Tyrion's cousins. Kevan  was not sure if that would work, for Lancel did not recover yet from his injuries at the Battle of Blackwater.
 * ​Tywin did not intend to marry Cersei to Loras, but to his older brother Willas Tyrell or Balon Greyjoy or Oberyn Martell by her choice, and it was much later in the novel. Cersei was not thrilled by either alternative "the old squid or the crippled dog boy".

The Climb

 * The bickering between Meera Reed and Osha does not occur in the novel. In fact, Osha, Rickon  and Shaggydog  are not even part of Bran's  party, having left on a different course after the Sack of Winterfell.
 * Meera did not hunt any rabbits, but fish and frogs.
 * Jojen had no dreams about Jon.
 * Tywin never has a conversation with Olenna  concerning Loras  and Cersei. At this stage in the book, Loras is already in the Kingsguard  so he cannot marry anyone. Cersei was offered to Willas Tyrell instead, a character that has been cut from the series, so this serves as a highly condensed version of that subplot.
 * Tywin made Mace Tyrell the offer of marrying Cersei to Willas, but Olenna foiled it because in her eyes Cersei was "too old and too used" for her precious one-legged grandson.
 * Tyrion never confronted Cersei about Mandon Moore.
 * Cersei never admitted that Tyrion saved the city by using wildfire. According to Tywin, she was (unjustly) given the credit for that.
 * Loras never acqaints himself with Sansa to the extent shown in the show. Sansa was not even offered Loras by the Tyrells, but his elder brother and the heir to Highgarden, Willas Tyrell.
 * Sansa has never been given early warning about her impending wedding to Tyrion. On the marriage day, she was taken from her room under threat of force right to the ceremony.
 * Shae knew about Tyrion's impending wedding to Sansa before he told her. She told him that she had heard a page telling Ser Tallad about it, who had heard it from a serving girl who overheard Kevan talking to Tywin about it.
 * ​Shae is not mad about Tyrion and Sansa's marriage.
 * Littlefinger does not give his chaos speech to Varys.
 * Ros does not exist in the book, so her execution in the episode was new material.
 * Interestingly, in the books Arya Stark actually does know some basic High Valyrian, which she learned as part of her lessons with Maester Luwin. Then again she's stated to not know it very well, as she's only a child and hasn't been studying it for many years, so it's debatable if even book-Arya would have been able to understand two other people speaking in fluent High Valyrian.
 * Melisandre says Thoros was sent to Westeros to convert King Robert to the religion of R'hllor. In the books, he was sent to convert the Mad King (the faithful of R'hllor believed Aerys' obsession with fire would make him a willing convert). Thoros did still hang around the royal court under King Robert and became one of his drinking companions, but he had even less luck preaching about the Lord of Light to Robert than he did to Aerys.
 * Jaime did not try to persuade Roose Bolton to let Brienne  go with him.
 * Roose said that Brienne would stay in Harrenhal for Vargo Hoat's entertainments, not under arrest for abetting treason.
 * The Starks, not the Freys, were the first to offer that Edmure, instead of Robb, to marry one of Lord Frey's daughter. The Freys accepted the offer.
 * Brynden Tully never threatened Edmure. On the contrary, he said "I am the last man in the Seven Kingdoms to tell anyone who they must wed, nephew. Nonetheless, you did say something of making amends for your Battle of the Fords".
 * Walder Frey never wanted Harrenhal in the book.
 * "Black Walder" Frey was not on a visit in Riverrun to negotiate the wedding with Lothar Frey, it was Walder Rivers.
 * Orell never cuts loose the rope to which Ygritte and Jon are clinging to. Orell's character was long dead, slain by Jon's raiding party.
 * Ygritte hates the Wall in the books, and never had any dreams of standing on top of it. She also never reveals to Jon that she knows where his true loyalties lie.
 * Jarl is leading the climb up the Wall in the books, not Tormund.
 * Jon and Ygritte are not among the dozen wildlings who first scale the Wall.
 * While climbing the Wall, large parts of ice broke off the Wall, Jarl and other climbers fell and were killed. Once the remaining climbers reached the top, they threw ropes to the wildlings on the ground. Ladders were pulled to the top of the Wall, and only then Jon, Ygritte and the other wildings climbed much more safely and conveniently (though the climb was still dangerous and cost more lives) than in the series.
 * In the books, Jon and Ygritte reach the top of the Wall around midnight, not in daylight.
 * After Jon and Ygritte reach the top of the Wall, she reveals what the secret power is that the wildlings have been looking for in the Frostfangs.

The Bear and the Maiden Fair

 * Robb Stark's wife Jeyne Westerling, changed to "Talisa Maegyr" in the TV series, never told him that she was pregnant. It is possible that Jeyne is pregnant in the later books, which chronologically would mean she became pregnant around this time if she has.
 * Neither Orell (who was killed by Jon in "A Clash of Kings") nor any of the Wildlings ever disapproved of the growing romance between Jon and Ygritte. Indeed, some of them encouraged it, and were confused by Jon's initial retience towards Ygritte.
 * The scene with Theon Greyjoy does not specifically happen in the books, but is loosely adapted from flashbacks given in later books. The books never outright state that Theon's torturers castrated him, but it was twice alluded to in "A Dance with Dragons".
 * There are minor book characters named Myranda and Violet, but they do not have anything to do with the Boltons and Theon's torturing.
 * The conversation between Sansa and Margaery about the marriage to Tyrion does not occur in the books. Sansa never discussed it with anyone, because she was not told until the wedding itself, and the Tyrells distanced themselves from Sansa after their plot was discovered.
 * The conversation between Tywin and Joffrey does not occur in the books.
 * The conversation between Tyrion and Bronn does not occur in the books.
 * Tyrion never gave any chain to Shae.
 * Shae was not upset at all about Tyrion's impending marriage to Sansa. On the contrary, she told him indifferently: "I don't care. She's only a little girl. You'll give her a big belly and come back to me." Tyrion was quite upset at Shae's indifference, which proved to him that she does not have any true feelings to him.
 * There is no mentioning in the book that there are 200,000 slaves in Yunkai.
 * Daenerys' meeting with the Yunkish envoy is different in the novel. First, the Yunkai'i meet her with an army of slave soldiers and sellswords at their back. Second, they do not offer her any ships to carry her to Westeros (that offer was made much earlier by Xaro Xhoan Daxos), but one chest of 50,000 gold marks (not bullions) which she does not keep when she rejects their terms. Third, she orders Drogon to breathe fire on the envoy as he leaves, setting his tokar (a Ghiscari garment) on fire.
 * The Yunkai envoy's name is the books is Grazdan mo Eraz.
 * Osha never mentions any husband or other relatives.
 * There was no goodbye conversation between Jaime and Brienne before he left Harrenhal.
 * As Jaime left Harrenhal, he said goodbye to the Brave Companions, promising them "I will be back. A Lannister always pays his debts".
 * Jaime never told Qyburn or anyone else except Brienne that he saved the residents of King's Landing.
 * Jaime did not ask Qyburn if he was expelled from the Citadel because "he fondled one boy too many". That comment may refer to the pedophile Septon Utt (so far did not appear in the series), another member of the Brave Companions, who used to molest and murder children until he was caught and hanged by the Brotherhood without Banners.
 * Jaime decided to rescue Brienne after having a fevered dream of her, not after hearing from Qyburn that Vargo Hoat/Locke refuses to accept the ransom her father offered. Jaime was irritated to hear that, but did not change his mind until after the dream.
 * While Jaime was gone, Vargo Hoat tried to rape Brienne, but she fought him and bit off one of his ears. When Jaime returned to Harrenhal, he noticed that Hoat's left side of his head is covered with bloody bandages.
 * Brienne's fight with the bear is different in the book. First, she fights it with a metal tourney blade. Jaime did not notice immediately it was a blunt sword but only after she stabbed the bear without causing any injury. Second, when Jaime arrives he is accompanied by 200 Northmen commanded by Steelshanks who outnumber the Brave Companions/Locke's men two-to-one. Third, Vargo/Locke tried to rape Brienne and she bit off his ear. Fourth, Steelshanks and several other Northmen killed the bear with a dozen or so crossbow bolts. Fifth, Jaime and Brienne do not climb out of the arena, the bear is killed before there would be need to do so.
 * Gendry never learns that he is Robert's bastard.
 * Orell never takes an interest in Ygritte (since he was killed by Jon in A Clash of Kings).
 * In the books, Margaery never tells Sansa that Tyrion might make a good husband. Instead, her brother Garlan, who doesn't exist in the series, does it. Also, in the books, it happens later, at the wedding itself.

Second Sons

 * The Hound does not give Arya a chance to kill him, but takes the rock from her and warns her "if you're stupid enough to try again, I'll hurt you".
 * The Second Sons are 500, not 2,000 (the Stormcrows are also 500).
 * It is not Grey Worm but Strong Belwas who offers Daenerys to cut Prendahl Na Ghezn's tongue when the latter talks rudely to her. When Mero talks rudely to Daenerys, none of her guards offers that.
 * Daenerys orders Jorah Mormont, not Barristan, to kill Mero first - when Mero is still in the tent and hears that. Mero is unimpressed, and continues the conversation.
 * The scene between Prendahl na Ghezn, Daario Naharis and Mero picking coins to decide who would assassinate Daenerys does not happen in the book. It is Mero and not Daario who sneaks into Daenery's camp after his defeat and flight from the Battle of Yunkai. Mero almost slays Daenerys before he is stopped and slain by Barristan Selmy (still disguised as Arstan Whitebeard). Only after that point, Selmy's true identity is revealed.
 * Daario is not a lieutenant but a captain of another sellsword company called the Stormcrows along with Prendahl na Ghezn and a character called Sallor the Bald (does not appear in the show). In the novels, it is these two characters that Daario beheads to gain the trust of Daenerys. He sneaked into her camp (with no malicious intent), but was caught by the Unsullied. He showed Daenerys the severed heads, and declared "the Stormcrows are yours". Mero was not part of the Stormcrows but a commander of the Second Sons, and so was not slain by Daario.
 * Darrio does not take Missandei hostage or any of Daenerys' servants.
 * Mero asks Daenerys for a wagon full of wine, and she cunningly agrees, so that the Second Sons will be too drunk to fight when her army attacks Yunkai.
 * Sansa does not tell Tyrion he looks handsome, because she figures that if she says such a thing - he will think she is either a fool or a liar. This is connected to the fact that Tyrion is much uglier in the books, and additionally his injury in the Battle of Blackwater was much more gruesome.
 * Shortly before the ceremony, Tyrion told Sansa that if she didn't want to marry him, they would wed her to Lancel instead, so if she preferred to marry Lancel - she could ask to.
 * Sansa and Tyrion are not married at the Great Sept of Baelor, but a local Sept at the Red Keep.
 * Sansa is 12 years old, not 14, when she is married to Tyrion.
 * The wedding scene between Sansa and Tyrion is different in the book. Sansa is a lot more distraught throughout the procedure, and outright refuses to bend down when Tyrion attempts to cloak her - her only act of defiance throughout the entire ceremony. Thus Tyrion had no choice but to stand on Dontos' back in order to cloak Sansa in the colors of House Lannister, while everyone had a good laugh. There was no chair that Joffrey took in the show.
 * After Tyrion thrusts his dagger into the table and tells Joffrey "Then you'll service your own bride with a wooden prick", he adds "I'll geld you, I swear it".
 * Tyrion and Sansa get fully undressed and enter bed, and Tyrion gropes Sansa's breast. Although she does not explicitly say "no", he realizes that she does not wish to have sex with him, and he does not want to force himself upon her.
 * When Sansa asks Tyrion what if she never wants him to touch her, he answers "that is why the gods made whores for imps like me" and climbs down off the bed.
 * Neither Shae nor anyone else checks Tyrion and Sansa's bed for stains of maidenhood blood.
 * The scenes between Gendry and Melisandre never happen in the book, although there is some truth to them. In the show, there are leeches gorging on Gendry's blood, but in the book, there are leeches gorging on Edric Storm's blood, an acknowledged bastard of King Robert present on Dragonstone. Edric's bloodletting is performed as medical treatment, but off-screen. Stannis comments offhandedly that Edric coughs, shivers, has a fever, and Maester Pylos has been leeching him.
 * Melisandre never gets intimate with anyone except Stannis (and that is only implied to take place off-screen).
 * Sam's encounter with the White Walker is different in the novel. Firstly, the White Walker that Sam slew in the book with the Dragonglass dagger occurred shortly after the Battle at the Fist of the First Men, when the surviving Night's Watch members were retreating back to the Wall. The creature that Sam encounters with Gilly is a Wight (a human slain by a White Walker and has risen again at their command), formerly a steward for the Watch named Small Paul, who carried Sam for a while during the retreat from the Fist, and was killed by the Other which was subsequently destroyed by Sam. In the novel, Sam sees many Wights surrounding him, most of which he recognizes as his fallen Black brothers (Chett, Lark, Softfoot, Ryles and others). He attempts to use his dragonglass dagger in this scene to kill the Wight of Small Paul, but fails as Dragonglass is only effective against White Walkers, and it shatters when he tries to stab the Wight with it. Sam tries his steel dagger, but for no avail, for Wights are not affected by stabbing of normal weapon. Luckily, Sam manages to grab a burnt wood and thrusts it into the Wight's mouth, thus destroying it, but there are many more wights attacking them. At that point, countless ravens swarm and attack the Wights, saving Sam and Gilly.
 * Sam does not have a sword (he lost it at the Fist), but dragonglass dagger and steel dagger.
 * The White Walker did not shatter but melted down when Sam stabbed it.
 * TV viewers might think it foolish that Sam left the dragonglass dagger on the ground where the White Walker died, instead of recovering such a valuable weapon. In the books, Grenn is present and tries to pick it up, but immediately flings it back to the ground because it is so cold from touching the Walker; it remains there on the ground wreathed in steam. Sam and Grenn wait till the dagger is warm enough to touch, then Sam tells Grenn to pick it up. Since so few dragonglass daggers were in the secret bundle that Jon found at the Fist, Sam wouldn't so carelessly leave behind the only weapon (as far as he knew at that time) that is lethal to the Others. The TV series reveals two episodes later in "Mhysa" that Samwell simply had multiple dragonglass daggers in his possession, so it was no particular loss that he didn't go back for the one he killed the Walker with. Still, given that there are so many White Walkers - it was not wise to lose even one dragonglass dagger.
 * Given that these scenes were moved around, so Sam killed a White Walker as they were retreating from the Fist in the books, Grenn picked up and kept the dagger Sam used to kill the White Walker. Sam later takes Lord Commander Mormont's dragonglass dagger when he dies at Craster's Keep, which Mormont had been given by Jon Snow.
 * The scene where Cersei threatens Margaery and informs her about House Reyne of Castamere does not happen in the novel, although the scene still voices a good deal of Cersei's interior monologues regarding Margaery and provides important backstory on the song.
 * In the books, Cersei was born six years after the Reynes and Tarbecks were destroyed by Tywin, hence she could not have seen the rotting bodies.
 * Stannis never comes to visit Davos in jail.
 * Melisandre is the only visitor Davos has while he is imprisoned. She denies Davos' accusation that she is responsible for Stannis' defeat at the Battle of the Blackwater, and for the death of four of Davos' sons. She explains Davos why she cannot make more Shadows (because it weakened Stannis too much), and offers him to have sex with her for making a shadow. Davos rejects her offer, because he does not wish anything to do with Melisandre and her dark witchcraft.
 * Stannis does not express sorrow for the death of Davos' four sons (just one son in the series) at the Battle of the Blackwater.
 * Stannis does not order Davos to swear that he will never harm Melisandre.
 * Stannis is more doubtfull about killing an innocent boy, and does not give Melisandre permission to do it yet.
 * The order in which Stannis names the "false kings" while burning the leeches is opposite to the order in the show: Joffrey, Balon and Robb. He also hesitates before naming Robb Stark, as he realises Robb's treason is not as bad as the others.
 * Gilly wouldn't give her babya name before he is two years old, according to the Wildlings custom that she follows.
 * Sam and Gilly meet a mysterious person who takes them to the Nightfort.

The Rains of Castamere

 * The Hound does not intend to kill the farmer. Instead he forces the farmer at swordpoint to give his cart, horses, casks and most of his clothes. Arya does not intervene. The farmer curses the Hound, but reluctantly complies. Neither of them knocks the farmer unconscious or otherwise physically harms him.
 * The guard does not send the Hound back, but tells him to unload the food by the feast tents.
 * Arya tells the Hound that there is no one worse than him. He tells her that his brother is worse.
 * Arya does not get close enough to see Grey Wind.
 * Three of the Frey soldiers notice the Hound and attack him. One of them chases Arya and nearly kills her. The Hound kills the three and saves Arya, then knocks her unconscious.
 * Before heading for the Twins, Robb issues a royal decree, by which he legitimizes Jon and makes him his legal successor. Catelyn objects due to her feelings toward Jon, but Robb insists. It is unknown what became of the decree. Robb orders Maege Mormont and Galbart Glover to travel north to Howland Reed. He might have given them the decree.
 * The musicians at the wedding are noted to be terrible (since they are really archers in disguise), whilst in the TV series they are quite talented.
 * The Starks meet Roslin shortly after their arrival, long before the ceremony.
 * Four of the Freys (Ryman, Edwyn, Petyr Pimple and Black Walder) welcomed the Starks. As they got closer, Grey Wind acted menacingly and causes Petyr's horse to rear and throw its rider. Apparently Grey Wind sensed that foul play was afoot. Unfortunately, the incident made convenient excuse for Lord Frey to demand that Grey Wind would be kept out of the wedding hall. Robb did not like it, but complied because he wished to appease Lord Frey for breaching their pact.
 * There was a bedding ceremony at Eddard and Catelyn's wedding. Catelyn muses about it during her brother's wedding: how Jory Cassel had torn her gown in his haste to get her out of it, and drunken Desmond Grell kept apologizing for every bawdy joke, only to make another, and when Lord Willam Dustin had beheld her naked, he'd told Ned that her breasts were enough to make him wish he'd never been weaned.
 * The "Rains of Castamere" song was a signal in the book to start the massacre and was played during the slaughter. In TV series, the signal was Lord Walder's speech after the music had ended.
 * A few of the wedding guests, among them Greatjon Umber and Dacey Mormont, fight the assailants, but to no avail.
 * Roose Bolton's last words before killing Robb are different in the book. In the book he says "Jaime Lannister sends his regards", while in the show he says "The Lannisters send their regards".
 * Walder Frey is much older and weaker in the novel, being unable to rise from his chair without help.
 * Lord Frey has several granddaughters and great-granddaughters named Walda, but no daughter by that name.
 * There are no Arwaya Frey, Derwa Frey, Waldra Frey, Janeya Frey, Neyela Frey and Freya Frey in the books.
 * Lord Frey introduces the following of his descedants:
 * Daughters: Arwyn, Shirei and Tyta.
 * Granddaughters: Ami, Marianne, Cersei (aka Little Bee), Merry, Alyx, Marissa, the twins Serra and Sarra, and three girls named Walda.
 * Grey Wind was not chained in a box in the novel. He was actually chained but released by Raynald Westerling, Jeyne/Talisa's brother when it became clear the House Frey men intended to put down the wolf. It is claimed Grey Wind killed four Frey wolfhounds and tore off the kennel master's arm before being brought down.
 * Sam and Gilly are heading for Castle Black, not Nightfort. Sam knows they are north of the Wall, but he is not sure how far east or west they might have strayed from the gate of Castle Black.
 * Ygritte does not defend Jon when the altercation with the old man and Summer occurs at Queenscrown. When Jon manages to escape, someone (Jon thinks it was her) fires an arrow at him, which pierces his leg.
 * Jon does not kill Orell at Queenscrown; he had killed him much earlier in the Skirling Pass when he was still with Qhorin Halfhand in the book A Clash of Kings. Yet, part of Orell's spirit somehow remained at his eagle. The eagle attacked Jon without provocation shortly before Jon and the Wildlings arrived at the Fist, injuring his face and almost plucking his eyes.
 * It is not Orell but some of the Thenns who heard noises from the tower.
 * The tower is in the centre of a lake and accessed via stone causeway hidden under the water. The causeway zigzags, making it difficult to follow.
 * The old man does not breed horses for the Night's Watch. He has only one horse. He appears to be a traveller, not resident of Queenscrown.
 * The old man does not try to escape or to fight. He says nothing to his captors. He only looks at Jon in accusation and appeal.
 * It is Styr who orders Jon to kill the old man.
 * It is not the first time Bran wargs into Summer.
 * Ygritte kills the old man by slitting his throat, not shooting an arrow at him.
 * The departure of Rickon, Osha and Shaggydog actually occurs much earlier, right after the Sack of Winterfell.
 * Osha, Rickon and Shaggydog do not go to Last Hearth. Their destination remains unknown till the book "A Dance with Dragons".
 * It is not Roose Bolton who tells about his marriage to Fat Walda Frey. Walda tells that to Wendel Manderly, not to Catelyn.
 * Catelyn does not take Walder Frey's wife Joyeuse Erenford as hostage, but his half-witted grandson Aegon aka Jinglebell. She tells Lord Frey "On my honor as a Tully, on my honor as a Stark, I will trade your boy's life for Robb's. A son for a son". Lord Frey answers "A son for a son, heh. But that's a grandson... and he never was much use". After Robb is killed by Roose, Catelyn keeps her word by slitting Jinglebell's throat.
 * Talisa/Jeyne was not at the wedding and thus did not die in the Twins. Robb and Catelyn decided that Lord Frey would take it as a slight if Robb's wife made an appearance at the Twins. Another reason was that while Robb was strong enough to put up with Lord Frey's rebukes, Catelyn feared that he would not sit quietly if Lord Frey insulted Jeyne to her face (indeed it nearly happens in the show). Thus Jeyne was left behind at Riverrun.
 * Brynden Tully was not present at the Red Wedding, as he stayed behind to hold Riverrun.
 * It is not Brynden Tully but Roose Bolton that excuses himself and exits in search of a privy.
 * Roose Bolton does not wear his normal clothing over his armor when he changes after his conversation with Catelyn. He comes back from the privy clad in full dark armor with a flowing pink cloak, showing the colours of House Bolton.
 * It is not Roose Bolton but Edwyn Frey whom Catelyn grabs, feels that he wears an armor and slaps him.
 * Many important Northern Bannermen were present at the Wedding but not shown on screen. These include Greatjon Umber, Smalljon Umber, Dacey Mormont, Marq Piper, Donnel Locke, etc. By the end of the massacre, the Freys and Boltons have killed at least one member of each house in the North, but spared only four people.
 * Only few of the wedding guests were spared, among them: Edmure Tully, Greatjon Umber, Patrek Mallister and Marq Piper. The Freys initially meant to take Catelyn prisoner, but she was killed.
 * When Catelyn begs Lord Frey to let Robb go, swearing that they will take no revenge, he looks at her in mistrust and says "Only a fool would believe such blather. D'you take me for a fool, my lady?".
 * After killing Jinglebell, Catelyn is driven to insanity. She scratches her face, her blood is mingled with tears, till the Freys disarm and kill her.
 * Catelyn is killed by Raymund Frey, not by Black Walder Frey.
 * Catelyn's body is thrown in the river.
 * Daenerys does not conquer Yunkai via a back gate. Her army destroys Yunkai's troops without actually invading the city, then Yunkai surrenders.
 * Wendel Manderly is shown at the wedding but not formerly introduced. He can be identified at the wedding by the merman on his clothing.
 * Of the three kings against whom Stannis performed the leech ritual, Robb is not the first to die.

Mhysa

 * Tyrion and Sansa do not get along even remotely well in the books. Every moment they spent together was tense and awkward. The conversation between them does not occur in the books.
 * Tyrion has never been called "demon monkey".
 * There is no mentioning in the books that Arya has ever put sheep dung in Sansa's bed.
 * There are no characters named Desmond Crakehall and Eldrick Sarsfield in the books.
 * After the Small Council meeting, Tywin and Tyrion discuss the murder of Rhaegar's wife and children by the Mountain and Amory Lorch, and Tywin admits it was overly cruel, and it was not necessary at all to kill Elia.
 * Tywin never mentions having wanted to kill Tyrion as a baby.
 * When Joffrey says he will show Sansa Robb's severed head, it is not Varys but Kevan who reminds him that Sansa is his aunt by marriage.
 * After Joffrey leaves, Cersei mentions the time he cut open a pregnant cat, and Robert beat him severely, breaking two of his baby teeth.
 * After Cersei leaves, Tyrion says that Joffrey is not Robert the Second, but Aerys the Third.
 * The scene where Arya and the Hound encounter the Freys is different in the novel. Firstly, Arya and the Hound are attacked when the fighting breaks out in the Stark/Tully camp outside the Twins. Sandor kills both of the Freys and then knocks out Arya to save her from running toward Catelyn and Robb and thus to her doom. In the novel, Arya did not attack the Freys or offer them money, as Sandor finished them off quickly.
 * Tyrion tells Sansa about her mother's and brother's death.
 * Varys never offers Shae a chance at a new life across the narrow sea.  In the book, she never exhibits any feelings of loyalty toward Sansa.
 * When Arya attacks the Frey man-at-arms after he boasts about stitching Grey Wind's head to Robb's body, she dropped the coin that Jaqen H'ghar gave her so that she would have an opportunity to strike. This portrays the way she dispatched the guard at the Gate of Harrenhal in A Clash of Kings and escapes with Hot Pie and Gendry. The multiple stabbing of the soldier by Arya portrays the way she killed another character later in the book.
 * Gendry was never brought to Dragonstone. In the book, another of Robert's bastards, Edric Storm, is in Stannis' castle for safekeeping. However, Davos did help Edric to escape to the Free Cities on board of Salladhor Saan's ship, along with a group of co-conspirators on Dragonstone who did not believe the sacrifice of the boy to the flames was honorable. Edric had no idea that his life was in danger, and Davos did not tell him that.
 * Melisandre does not burn the letter which Davos shows Stannis.
 * Stannis does not tell the guards to take Davos away. He draws Lightbringer and intends to kill Davos on the spot, unless Davos can give good reason to spare his life.
 * Melisandre does not convince Stannis to spare Davos, on the contrary: she tells Davos that what he did was wrong. It is Stannis himself who decides to pardon Davos.
 * The reason for sparing Davos is not Melisandre stating that they need him, but Stannis realising Davos reminded him of his true duties as King: protecting the realm.
 * The scene between Roose Bolton and Walder Frey does not occur in the novels.
 * It is not Walder Frey but his son Emmon who is granted the title of Lord of Riverrun.
 * While it is heavily implied twice in the book A Dance with Dragons that Theon had lost his manhood, the Boy, now revealed to be Roose Bolton's bastard son Ramsay, did not send his penis in a box to Balon Greyjoy at Pyke. He sent piece of skin from Theon's little finger to Roose, and Roose showed that to Robb and Catelyn before the Red Wedding - the only time in the entire book A Storm of Swords that Theon's status is reported.
 * Ramsay never sends any messages to Balon. He sends a warning message to Asha, to which he encloses piece of Theon's skin (not any body part) without specifying his status, but it happens much later.
 * Asha/Yara believes that Theon is dead. She never intends to rescue him.
 * The scene with Balon and Yara does not occur in the books. At this point, Yara is present holding Deepwood Motte and Moat Cailin as the Ironborn continue their campaign in the north. Many of the Ironborn believe Theon died at the Sack of Winterfell, as Yara/Asha later lamented that many of the bodies in Winterfell were unrecognisable when she arrived, so Ramsay never sent a letter to Pyke letting the Greyjoys know they held Theon captive. She thus does not prepare to attack the Dreadfort in the novel.
 * Shae does not love Tyrion in the books. Quite the opposite, in fact. Tyrion knows that well, and chides himself for not breaking up with her.
 * On the way to King's Landing, a knight named Bertram Beesbury meets Jaime and Brienne, and tells them about the Red Wedding. Brienne is emotionally devastated to hear about the demise of the Starks. Jaime feels sorry for her, although the Starks were the enemies of his house, and tries unsuccessfully to console her.
 * Jaime, Brienne, Qyburn and their escorts do not arrive at King's Landing until later in the book. They arrive horseback and are welcomed at the gate of the Red Keep by three of the Kingsguard and a dozen Gold Cloaks, rather than entering side gate on foot and unnoticed.
 * Neither Ygritte nor any of the other Wildlings catch up with Jon on his way back to Castle Black. Jon fully escaped the Wildlings after the incident in Queenscrown when Bran warged into Summer to allow Jon an opportunity to escape. He is shot in the leg by one arrow, not three, which he believes may belong to Ygritte.
 * Jon never tells Ygritte that he loves her.
 * Sam does not show the dragonglass weapons to Bran. He had only one dragonglass dagger (which he took from Mormont's body), and that dagger shattered when he fought the wight that attacked him and Gilly.
 * Bran and his escorts could not pass the Black Gate till Sam recites the Night's Watch oath.
 * Bran does not tell his companions about the Rat Cook, but recalls that Old Nan told him the story.
 * It is not Bran but Jojen who denies his identity when Sam recognizes him.
 * Before departing, Bran makes Sam swear three times that he will say nothing about meeting him, not even to Jon.
 * Sam and Gilly are no​t at Castle Black when Jon first arrives. They arrive much later.
 * Gilly does not name her baby, following the Wildling custom not to name babies before they are two years old.
 * The brothers who remained at Castle Black sent distress messages to all the five kings and many lords long before Sam returns with Gilly. One of those messages reached Dragonstone, but Alester Florent (the former Stannis' Hand) did not show it to Stannis. Only by chance, Maester Pylos gave this letter to Davos while he taught him to read.
 * Arya and Sandor were not in the Twins long enough to see Robb with Grey Wind's head stitched on. In the novel, Robb's iron crown was nailed onto Grey Wind's head.
 * When Dany greeted the liberated slaves of Yunkai, she trotted through the crowd on her silver horse, who at that point in the programme already died in the Red Waste. In fact, so far the silver mare is alive and well.
 * The conversation between Tyrion and Cersei does not occur in the novels.
 * The reason that Tywin does not press his intention to marry Cersei to Willas Tyrell (in the series - Loras) anymore is that Olenna Tyrell forced her son Mace to reject Tywin's offer, claiming that Cersei is too old and too "used" for her precious grandson. Maybe it was done as payback for foiling the Tyrells' plan to marry Sansa to Willas. Tywin decides not to mention it anymore.
