House of the Dragon season 3 has officially killed off Jacaerys Velaryon, but his death in episode 1 deviates significantly from the source material, Fire and Blood by George R.R. Martin. In the show, Jace meets his end during the Battle of the Gullet after a chaotic sequence involving multiple dragons, including Rhaena Targaryen and her dragon Sheepstealer.
How Jacaerys Dies in the Show
In the season 3 premiere, Jacaerys takes his dragon Vermax into the Battle of the Gullet. Initially, Sharako Lohar nearly drags both dragon and rider into the water with a bolt shot, but Baela Targaryen and Moondancer intervene to save them. However, moments later, Rhaena appears on Sheepstealer, throwing the battle into chaos. Vermax is ultimately taken down, and Jacaerys, stranded in the water, is shot by multiple arrows, leading to his death.
How Jacaerys Dies in the Book
In Fire and Blood, the Battle of the Gullet unfolds differently. Sheepstealer does appear in the battle, but the dragon's rider remains unknown in the book. There is no indication that Rhaena Targaryen rides Sheepstealer into combat. Furthermore, Sheepstealer is not responsible for Jacaerys's death in the book. The show's decision to involve Rhaena directly in Jace's demise is a major change from the established canon.
Impact on Rhaena's Storyline
This alteration suggests that Rhaena will have a significant arc in season 3, grappling with her role in her nephew's death. According to the show's creators, the change aims to deepen Rhaena's character and explore the consequences of her actions. As one source close to production noted, "This will force Rhaena to confront the cost of war and her own ambition." Viewers are divided on whether the change improves the narrative, but it certainly sets up dramatic tension for the remainder of the season.
What This Means for the Series
House of the Dragon season 3 continues to adapt Fire and Blood with creative liberties, as seen in earlier episodes. The Battle of the Gullet is a pivotal event in the Dance of the Dragons, and Jace's death marks a turning point for Team Black. With Rhaena now implicated, the show may explore new alliances and conflicts not present in the book. Fans will have to wait and see how the rest of the season unfolds.
