The finale is titled “The Treasons at Tumbleton” (Les Trahisons à Tumbleton) and aired on August 9, 2026, on HBO. With a runtime of 1 hour and 11 minutes, it was directed by Andrij Parekh and written for television by Ryan Condal and Ti Mikkel. The reception has been excellent: it currently holds a 9.0/10 on IMDb with approximately 28,000 votes and 92% on Rotten Tomatoes.
In House of the Dragon Season 3, Episode 8, The Treasons at Tumbleton, the Dance of the Dragons reaches a new breaking point. As the unexpected return of Aegon II and Sunfyre threatens Rhaenyra’s legitimacy, the armies converge on Tumbleton, where the war turns into a veritable bloodbath. The Dragonseeds’ loyalty wavers, Ulf and Silverwing upset the balance of power, and several major characters meet tragic fates. Meanwhile, in King’s Landing, Rhaenyra sinks deeper into an increasingly authoritarian and prophetic vision of her reign, while Helaena Targaryen meets a tragic end. Amid betrayals, dragons, and major deaths, this finale profoundly reshuffles the deck ahead of Season 4.
Positive Fan Reactions
On the positive side, “The Treasons at Tumbleton” won over a significant portion of the audience by finally delivering the true chaos promised by the Dance of Dragons. After a season that was consistently criticized for its pace and its many setup episodes, the finale gives the impression that the consequences of all these plotlines are finally beginning to explode simultaneously. Battles, betrayals, major deaths, dragons, and political upheavals follow one after another, to the point that some fans are directly giving it 9/10 or 10/10. In a discussion about the episode, one viewer explains that they “loved” the finale and gave it a 10/10 after a first viewing, while another highlights the impressive sheer volume of events and action packed into a single episode.
The Battle of Tumbleton is clearly one of the most appreciated elements. Several fans praised its scale, its atmosphere, and above all the way it portrays war as something deeply chaotic rather than as a heroic clash between two clearly identifiable armies. One viewer, in particular, compared it to Stannis’s attack on King’s Landing in Game of Thrones, but on a much larger scale. The decision to show the battle in broad daylight was also well-received: the violence remains constantly visible, and viewers cannot escape what is happening to both the soldiers and the residents of Tumbleton.
Roderick Dustin and the Winter Wolves were likely the most popular supporting characters in the finale. The Northerners’ enthusiasm for the fight, their charge, and especially Roderick’s final stand greatly entertained viewers. In the Reddit discussion containing spoilers from the book, the comment stating that the poster loved seeing the Northerner “have the time of his life” during the battle surpassed 1,500 upvotes. Other viewers point out that his ending fits the character perfectly: Roderick and his men came south knowing they had little chance of returning home and were specifically seeking a death worthy of being told.
The duel between Roderick Dustin and Ormund Hightower plays a major role in this success. Even though the series alters certain elements of Fire & Blood, fans appreciated the almost excessive energy of this confrontation amid the chaos. The deaths of both men, ultimately caused by Ulf and Silverwing, also add a particularly cruel irony to the sequence: two key combatants in the war perish not in a perfectly orchestrated heroic conclusion, but because an out-of-control dragonseed suddenly decides to burn everything around it. For some viewers, this violent absurdity perfectly captures exactly what the war has become.
Ulf and Silverwing have, in fact, played a major role in Tumbleton’s unpredictability. The series gradually transforms Ulf into a veritable ticking time bomb: Rhaenyra gave him one of the most powerful weapons in the world without ever securing his true loyalty. When he finally acts on his own, the consequences become catastrophic for virtually everyone. Many viewers appreciate this way of showing that dragons cannot simply be counted as military units belonging to one side or the other. As soon as a rider changes his objective, the entire military balance of Westeros can collapse.
This idea also ties into one of the aspects of the finale most championed by its fans: no one really controls this war anymore. One particularly popular post following the episode’s airing, with nearly 2,000 upvotes, specifically praises the episode for its portrayal of the futility of the conflict. According to this interpretation, the protagonists’ egos, pride, thirst for power, and stubbornness have created a tragedy that now completely transcends those who started it. It is therefore no longer really a matter of determining which side deserves to win: each faction is now contributing to the destruction of the kingdom it claims to want to rule.
Rhaenyra’s transformation is also one of the elements most appreciated by some fans, including certain viewers who were previously very critical of Seasons 2 and 3. One particularly interesting reaction comes from a fan who explains that they had heavily criticized the series before acknowledging that Rhaenyra’s arc and the Battle of Tumbleton were particularly well-executed in this finale. For these viewers, seeing Rhaenyra become truly authoritarian represents a long-awaited development.
The queen is no longer simply seeking to convince Westeros that she is Viserys’s rightful heir: she is beginning to believe that her destiny grants her the right to impose that legitimacy. Her obsession with the prophecy and her decision to present herself as the Prince Who Was Promised reveal a Rhaenyra who is increasingly trapped within her own certainty. Some fans particularly appreciate that the series has finally decided to make the character much less likable. One viewer explained that they especially enjoyed seeing her no longer tolerate opposition in this episode, even if it deliberately transforms her into a harsher and more unpleasant person.
This evolution also allows Emma D’Arcy to deliver a much more aggressive performance. Even in discussions that are particularly critical of Rhaenyra’s characterization, the actress’s performance continues to be praised. Among readers of Fire & Blood, some are simply delighted to see Rhaenyra actually take action and believe this change finally allows Emma D’Arcy to explore a much darker side of the character.
But while Rhaenyra becomes more unsettling, Aegon II paradoxically continues to gain popularity. Tom Glynn-Carney is once again among the most praised actors in the finale. His portrayal of Aegon—now physically broken but still determined to survive—seems to have transformed a character who was once widely disliked into one of the series’ most entertaining protagonists.
One line in particular became an instant hit after the episode aired: when Aegon cheerfully announces that he’s alive. In the spoiler-free discussion thread for the book, the reaction to this scene has garnered over 3,500 upvotes, while another comment calls Tom Glynn-Carney’s delivery of this line the best line of the entire series. Several fans also say they enjoyed each of his appearances this season.
His reunion with Aemond also goes over particularly well with the audience. The dynamic between the two brothers remains deeply hostile: Aegon obviously hasn’t forgotten what Aemond did to him, but understands that he may still need him. Some readers particularly appreciated this attitude, which essentially consists of making it clear that he still intends to take revenge, but only after using him. Here again, Tom Glynn-Carney’s performance is regularly cited as one of the highlights of the episode and even of the entire season.
Ramin Djawadi’s music is also among the most universally praised elements. In the spoiler-filled discussion about the book, a comment simply giving the music “10/10” received several hundred upvotes. The Northerners’ charge at Tumbleton, in particular, reminded some viewers of the atmosphere of the Battle of Helm’s Deep in The Lord of the Rings. The final editing is also particularly praised for its ability to bring together the characters’ various emotions and situations before the season’s conclusion.
More broadly, the finale seems to have achieved something that Season 2 struggled much more to accomplish: giving the impression that a season has truly just ended. Even among critics who acknowledge certain flaws, several believe that the previous episodes ultimately set the stage for the events that come to a head here. Tell-Tale TV gives it 4/5, Vulture also gives it 4/5, while Rotten Tomatoes currently lists a 92% positive critic score. FandomWire, for its part, gives it an 8/10 and highlights that it’s the season’s most action-packed episode.
Some critics go even further in comparing it to Game of Thrones. A review published after the episode aired suggests that the finale comes close to what the original series was capable of in its best battle episodes, specifically citing “Battle of the Bastards”. Tumbleton works because the battle doesn’t just offer spectacle—it simultaneously shows the political and human consequences of this war.
Ultimately, the positive reviews surrounding “The Treasons at Tumbleton” highlight an episode that finally and fully embraces the darkness of the Dance of the Dragons. Tumbleton offers no real victory: Ormund dies, Roderick dies, Ulf spirals out of control, civilians are massacred, the Dragonseeds begin to slip from Rhaenyra’s grasp, and the queen herself gradually sinks into an almost messianic conviction of her own destiny. At the same time, Aegon and Sunfyre have survived, and Aemond remains in the game.
Fans’ Negative Reactions
Despite the many positive reactions to “The Treasons at Tumbleton”, the Season 3 finale of House of the Dragon is also far from having convinced everyone. Interestingly, even some of its critics acknowledge that the episode is technically impressive and that the Battle of Tumbleton features several spectacular sequences. The problem lies more with the writing and the payoff of the storylines developed throughout the season. For some fans, after seven episodes spent setting up the various pieces on the chessboard, the finale should have delivered a much more dramatic upheaval. One particularly critical reaction argues that the episode is well-made when viewed in isolation, but far more disappointing when considered as the conclusion of an entire season.
The Battle of Tumbleton itself is far more divisive than one might think. While its scale and visual effects have been praised, some viewers criticize it for a lack of strategic clarity. The movements of the armies sometimes seem difficult to follow; certain forces appear on the battlefield very suddenly; and many fans have identified a problem already criticized in the final seasons of Game of Thrones: the impression that the distances and geography of Westeros are adapted to the immediate needs of the plot. One particularly harsh review describes Tumbleton as a chaotic clash in which the positioning of the various armies lacks coherence.
But the main frustration surrounding Tumbleton likely concerns the infamous “betrayals” hinted at even in the episode’s title. For readers of Fire & Blood, this name obviously holds special significance and had raised high expectations regarding the Dragonseeds. However, some fans feel that the series failed to give Ulf’s betrayal the full dramatic weight it should have had. His defection had been foreshadowed for several episodes, to the point of becoming almost predictable, and the different treatment given to Hugh Hammer significantly alters the dynamics of the event. For these viewers, seeing both Dragonriders switch sides would have constituted a much greater military blow to Rhaenyra. The choice to focus this betrayal primarily on Ulf therefore, in their view, diminishes the impact of the plot twist.
Hugh is precisely one of the characters whose portrayal divides readers the most. The series has significantly expanded his personal story and motivations compared to the source material, particularly through Kat. Some appreciate this effort to give him more humanity, but others feel that this subplot ultimately unnecessarily complicates his role in the events at Tumbleton. Kat’s death certainly gives him new motivation, but it also postpones a development that some readers were specifically expecting during this battle. For them, the finale thus transforms a famous event from Fire & Blood into a setup for a new plotline that won’t reach its true payoff until Season 4.
The disappearance of several major dragons during the battle was also noted. Caraxes takes part at the start of the clash but then becomes much less prominent once Silverwing truly enters the fray. Some viewers found it strange that such an important dragon could practically vanish from a situation where another dragon is running amok. One reaction directly highlights this issue by asking where the other dragons went during part of the Tumbleton battle. Budgetary and technical constraints can obviously explain certain decisions, but for a series specifically depicting a civil war among dragonriders, their absence during strategic moments can quickly become noticeable.
Daemon also shares this frustration. Some fans would have liked to see him make greater use of Caraxes and act like the commander and experienced dragonrider he’s supposed to be. Instead, a significant portion of his time in Tumbleton shows him fighting directly on the ground. For his critics, seeing one of the most important characters in the Dance fighting with a sword among the soldiers—even though he possesses Caraxes—is a dramatic choice but one that’s strategically difficult to justify.
The portrayal of Daeron Targaryen is also among the major disappointments voiced after the finale. After being absent from the first two seasons and then eagerly awaited by readers, Daeron was logically expected to become one of the major new additions of this third season. However, some fans feel that he ultimately ends the season without having accomplished enough decisive actions. One critical reaction specifically highlights the omission of several events that helped build his reputation in Fire & Blood. His mysterious fate after Tumbleton is therefore seen less as an exciting cliffhanger and more as yet another way to postpone his true development until the next season.
But Helaena Targaryen is probably the character whose fate has drawn the most criticism from *Fire & Blood* readers. Her death was naturally expected by those familiar with the story, but its portrayal in the series has deeply divided audiences. Some fans, in particular, regret the removal of Maelor, arguing that this decision sets off a chain reaction of changes to several events and weakens the circumstances leading up to Helaena’s death. One reaction posted after the finale argues that the character was deprived of a significant part of her story and that her conclusion lacks the impact it could have had.
This criticism is all the more pointed given that Season 3 seemed to be finally starting to develop Helaena. Her powers as a dreamer were becoming more explicit, her relationship with Dreamfyre was being explored more deeply, and the character was finally beginning to clearly express her thoughts. Some viewers therefore found it particularly frustrating to see her die precisely at the moment when she was gaining narrative importance. For these fans, her death feels less like the culmination of an arc and more like the abrupt interruption of a development that had only just begun.
Helaena’s pregnancy also makes her suicide harder for some viewers to accept. The series establishes that she knows part of the future through her visions, knows that Aegon is alive, and still has an unborn child. Many fans therefore wonder why she chose this particular moment to die and feel that her motivations deserved to be further explored on screen. It is not necessarily the suicide itself that is problematic—it is part of the Dance’s history—but the narrative path taken to reach it after all the changes made by the adaptation.
Rhaenyra’s transformation is also extremely polarizing. While some fans are finally delighted to see a more authoritarian and unsettling queen emerge, others feel that this evolution happens too abruptly. Her execution of the High Septon, her treatment of Helaena, and especially her claim to the prophecy of the Prince Who Was Promised have sparked a great deal of discussion. Some viewers find the Rhaenyra in the finale unstable and far less politically convincing than she should be. One critical reaction, in particular, describes her speech as unconvincing and deems her behavior toward the High Septon especially clumsy.
The prophecy of Aegon the Conqueror remains a sensitive topic among fans. Since the first season, House of the Dragon has given A Song of Ice and Fire considerable weight in shaping Rhaenyra’s motivations. For some viewers, this storyline works because it shows how a prophecy can gradually become a dangerous justification for power. For others, the series now overemphasizes this aspect and turns a particularly complex dynastic war into a story centered on a prophetic destiny. The fact that Rhaenyra proclaims herself to be connected to the Prince Who Was Promised takes this idea even further and, according to her critics, risks diverting attention from the true political stakes of the Dance.
Aemond is also among the characters that some viewers consider underutilized. Despite having Vhagar, the largest living dragon in Westeros, his storyline remains confined for much of the season to Harrenhal and Alys Rivers. Many fans would have preferred to see him lead his destructive campaign through the Riverlands and truly make use of Vhagar. One particularly critical reaction in the aftermath of the finale simply asks: where was Vhagar all season?
This ties into a more general frustration: despite a season dedicated to the Dance of the Dragons, several of the most important dragons ultimately spent a great deal of time off-screen. The finale was theoretically supposed to be an opportunity to bring together as many of these forces as possible: Aegon and Sunfyre, Aemond and Vhagar, Daemon and Caraxes, Rhaenyra and Syrax, as well as the Dragonseeds. Some fans therefore regret that Tumbleton didn’t make more of this exceptional gathering of characters and dragons.
More broadly, readers of Fire & Blood criticize the finale for the accumulation of changes made since the adaptation began. The removal of Maelor, the alteration of Daeron’s storyline, the changes involving Hugh and Ulf, Helaena’s development, Alicent’s role, and the changes made to the various battles are no longer minor, isolated adaptations. Each modification now has consequences for subsequent events. In fact, several reactions following the finale immediately echoed George R. R. Martin’s past criticisms regarding the ripple effects that the removal of a character can cause.
Ultimately, this is what stands out most in the negative reviews: the problem isn’t necessarily that the series differs from the book, but that some fans can no longer find the logic that connected the various events in *Fire & Blood*. A change may work on its own, but it then forces the writers to invent a new reason for an event—which was otherwise retained—to occur. Helaena is probably the most obvious example of this difficulty in the finale.
