The third season of House of the Dragon opened with the Battle of the Gullet, one of the most important clashes of the Dance of the Dragons and one of the most anticipated events for those familiar with Fire & Blood. The HBO series has respected the essential point of George R.R. Martin’s book. The way in which that shocking death is reached, however, has been modified.
WARNING: contains spoilers for the first episode of House of the Dragon 3
How Jacaerys Velaryon dies in House of the Dragon 3?
In the first episode of the third season, Jace enters the Battle of the Gullet riding Vermax. The clash involves the Velaryon fleet, the Triarchy, and the Blacks’ front, already marked by the consequences of the war against Aegon II and Aemond. Jace is no longer just the son to be protected: after the second season, he took on a more active role, sought alliances for his mother, and advocated for the need to use new dragon riders to rebalance the conflict. During the battle, Vermax ends up exposed to enemy fire. The series also builds the sequence around the chaos generated by Sheepstealer, the wild dragon that Rhaena cannot fully control. In the confusion, Vermax flies too low, gets hit, and crashes into the Gullet. Jace manages to free himself from the saddle and survive for a few moments in the water, clinging to the remnants of the battle. The enemy fleet spots him and strikes him with darts and arrows. Death comes thus, not in a duel between princes or in a direct confrontation with Aemond, but in the midst of a naval battle where the sea, the weapons of men, and the chaos among dragons become fatal.
The choice is consistent with the character. Jace dies in an attempt to be useful to the cause of the Blacks, not as a passive victim. The series insists on his need to prove his worth, also due to the doubts that have never been erased about his legitimacy. For Rhaenyra, however, the loss carries a political weight even before a military one: Jace was her most credible heir, the son raised to succeed her, the prince on whom the continuity of her line was based.
What happens instead in the book Fire & Blood In Fire & Blood?
The Battle of the Gullet has a different structure. The Triarchy attacks to strike the Velaryon fleet and break the Blacks’ control over the eastern shores. Before the clash, Jacaerys arranged for the departure of his younger half-brothers, Aegon and Viserys, sent to Pentos on the ship Gay Abandon. That very ship is intercepted, opening an important part of the battle that was not maintained in the same way in the series. In the book, Jace fights on Vermax alongside other dragon riders. The battle involves the new dragon riders: Addam of Hull on Seasmoke, Hugh Hammer on Vermithor, Ulf White on Silverwing, and Nettles on Sheepstealer. The Black side then deploys multiple dragons simultaneously against the Triarchy. The scene is described as a great naval and aerial battle, with fire from above, burning ships, confusion, and enormous losses.
Jace’s death occurs when Vermax flies too low. The dragon could have been hit by a dart in the eye or hooked by a grapnel, a hook used by ships. In any case, Vermax crashes into a burning galley or among the wreckage of the battle. Jace manages to jump away and reach some floating wreckage, but he is hit by the Myrish darts until he sinks into the sea. The strategic outcome is ambiguous. The Blacks do not lose the war on the Gullet, because the Triarchy suffers heavy damage and fails to definitively break the power of the Velaryon fleet. But for Rhaenyra, the loss is devastating: Jace was her eldest son, the Prince of Dragonstone, and her direct heir.
The most important difference between the series and the book
The most obvious change concerns Sheepstealer. In the book, the wild dragon is not bonded to Rhaena, but to Nettles. The girl is one of the dragonseed, that is, one of the people of possible Valyrian blood called to attempt to claim the dragons left without riders. Nettles succeeds where many fail: conquers Sheepstealer with patience, bringing him sheep every day until he is accepted. House of the Dragon has taken a different path. Nettles has not been introduced, at least so far, and the wild dragon storyline has been absorbed by Rhaena. The change is not just nominal. It changes the meaning of the story. In the book, Sheepstealer expands on the discourse of dragonseed and the power of dragons outside the more recognizable Targaryen nobility. In the series, however, it becomes part of Rhaena’s personal journey, a Targaryen who grew up with the burden of not having her own dragon while her sister Baela rides Moondancer.
Inserting Rhaena on Sheepstealer in the Battle of the Gullet also shifts the dramatic responsibility of the scene. In the book, Sheepstealer is one of the dragons aligned with the Blacks, ridden by Nettles. In the series, its presence introduces an element of disorder: Rhaena doesn’t really control him, and the dragon’s behavior contributes to the chaos that leads Vermax onto the wrong path. Jace dies anyway as in Fire & Blood, but the visual and narrative cause of his exposure to danger changes.
Why was the series removed Nettles and changed Rhaena
The choice to link Sheepstealer to Rhaena seems to address two needs of the adaptation. The first is narrative: House of the Dragon had already introduced many new dragon riders in the second season, including Addam, Hugh, and Ulf. Adding Nettles would have required time, independent development, and a new relationship with Daemon, which is central to the book. Moving Sheepstealer to Rhaena allows the series to use a character already present, with a clear frustration and a defined place in the family. The second requirement concerns the theme of legacy. Rhaena is the daughter of Daemon and Laena Velaryon, the granddaughter of Corlys and Rhaenys, and the sister of Baela. She has Targaryen and Velaryon blood, but until now she has remained without the most visible proof of belonging to the world of dragons. Sheepstealer thus becomes the way the series gives her a more active role. The price, however, is the loss of Nettles, a figure very different in social origin, political function, and relationship with the very idea of Valyrian blood.
In the book, Nettles challenges dynastic privilege: she is not a princess, she has no secure place in the court genealogies, yet she manages to ride a dragon. In the series, the discourse remains more internal to the Targaryen family. It’s a more compact choice on a television level, but less radical on a thematic level.
The Dragon Knights: Another Major Change In Fire & Blood
The Battle of the Gullet sees more dragonseed in action. Addam, Hugh, Ulf, and Nettles participate in the clash alongside Jace. This fact makes the battle the first true military test of the Red Wedding: Rhaenyra has just expanded her arsenal of dragons and is using them against the Triarchy. The series changes this distribution. The first episode of the third season focuses the clash on Jace, Vermax, Rhaena, Sheepstealer, and the Velaryon fleet, leaving the other new knights more in the background. It is a significant change because it isolates Jace’s death within a scene that is more emotionally controlled. Instead of presenting a large coordinated offensive by the dragonseed, the episode works on the fragility of control: a wild dragon, an inexperienced knight, a naval battle difficult to manage, and an heir who ends up in the worst part of the clash.
The difference also alters the political weight of the dragonseed. In the book, their participation in the Gullet immediately makes them protagonists of the war. In the series, their impact may be diluted in the upcoming episodes, leaving room for more gradual developments on Hugh, Ulf, and Addam.
The ship Gay Abandon and Rhaenyra’s young children: what’s missing in the series?
Another important difference concerns the Gay Abandon. In the book, Jace organizes the departure of the younger brothers, Aegon the Young and Viserys, sending them to Pentos to keep them safe. The Triarchy intercepts the ship: Aegon manages to escape on Stormcloud, while Viserys is taken prisoner and believed dead.
This part is crucial in Fire & Blood because the Battle of the Gullet does not only affect Jace. It also endangers Rhaenyra’s other children and opens up consequences that will return later in the dynasty’s history. In the series, the battle is constructed without giving the same weight to that narrative line. The result is an episode more focused on Jace and the fleet, less scattered in managing the Targaryen children and their fate.
The removal or reduction of Gay Abandon also changes Jace’s role. In the book, his death comes after a series of strategic decisions made by him: the sending of the brothers, the management of the dragonseed, the defense of the maritime front. In the series, Jace remains an operational prince, but the tragedy is mainly tied to the battle itself and the chaos generated by Sheepstealer.
Sharako Lohar, Alyn, and the other deaths changed by the series
The series adds other differences compared to the book. One of the most notable concerns Sharako Lohar. In the book, the commander of the Triarchy survives the Battle of the Gullet, even tho the expedition ends disastrously for the Free Cities allied with the Greens. In the series, however, Lohar dies during the clash, killed by Alyn of Hull.
This choice strengthens Alyn, who emerges from the battle with a more prominent role compared to the literary chronicle. The series needs to quickly build its weight alongside Corlys and within the Velaryon line, and the confrontation with Lohar offers him a direct moment of affirmation. The fate of Corlys is also left in a zone of television uncertainty, while in the book the Sea Serpent survives and continues to play a role in the aftermath of the Dance.
The result is a more selective but also more spectacular Battle of the Gullet in terms of the characters involved. Fire & Blood recounts a historical slaughter with thousands of deaths, a devastated fleet, and a complex military outcome. House of the Dragon focuses the loss around a few recognizable faces, increasing the immediate impact for the viewer.
What changes for Rhaenyra after Jace’s death
The death of Jace deprives Rhaenyra of her most solid heir. After Lucerys, another son falls in the war born from Viserys’s succession. The difference is political: Lucerys was the trauma that had erased the compromise; Jace was the future of the black cause. Losing him means weakening the line of continuity that Rhaenyra was supposed to follow on the Iron Throne.
The presence of Sheepstealer in the sequence adds a bitter element. Rhaenyra chose to expand the use of dragons to counter Vhagar and the Greens, but the first major battle of the third season immediately shows how fragile that control is. The dragons give the Blacks more strength, but they also increase the margin for error. In the book, this idea is conveyed thru the dragonseeds and their brutal entry into the war; in the series, it mainly comes thru Rhaena and a wild dragon that doesn’t really respond to commands.
House of the Dragon has therefore maintained the fate of Jacaerys, but has changed the function of his death. In Fire & Blood, the Gullet confirms the enormous cost of the Blacks’ military strategy and opens up dynastic consequences also related to the younger brothers. In the series, Jace’s death becomes the first major signal of the third season: the dragon war cannot be controlled even by those who think they need it to win.
