Warning: This article contains major spoilers for House of the Dragon, Season 3, Episode 1. Proceed with caution.
The long-awaited return of HBO’s House of the Dragon has sent shockwaves through the fandom, delivering a season premiere that is as brutal as it is narratively seismic. While the political maneuvering of the Dance of the Dragons has defined the series thus far, the Season 3 premiere brought the conflict to a harrowing, visceral head with the long-anticipated "Battle of the Gullet." Amidst the fire and fury of dragon warfare, the production delivered its most devastating blow yet: the death of Jacaerys "Jace" Velaryon, the heir to the Iron Throne and the son of Queen Rhaenyra Targaryen.
A Fatal Descent: The Mechanics of the Battle
The sequence, which has already been hailed by critics and fans alike as one of the most cinematic moments in the history of the Game of Thrones franchise, saw Jace and his dragon, Vermax, engaged in a desperate aerial defense over the open ocean.
The choreography of the battle highlighted the vulnerability of even the most formidable beasts. As Jace attempted to turn the tide of the naval skirmish, enemy forces utilized a calculated, brutal tactic: deploying massive harpoons and weighted chains. The imagery of Vermax being dragged toward the churning depths by an anchor—a sight that effectively grounded the dragon and neutralized its primary advantage—served as a masterclass in tension.

For the audience, the sequence provided a glimmer of hope as Jace momentarily resurfaced after his mount was lost to the sea. However, that hope was swiftly extinguished by a volley of arrows, marking the definitive end of the young prince’s journey. The sequence was not merely a tactical defeat for the Blacks; it was a character-defining moment of tragedy that has fundamentally altered the trajectory of the series.
A Legacy of Preparation: Harry Collett on the End of an Era
For 22-year-old English actor Harry Collett, who has portrayed Jace since the show’s debut, the conclusion of his character’s arc was not a sudden surprise, but a long-held secret. In an exclusive postmortem interview with Gold Derby, Collett revealed that he had been aware of his character’s ultimate fate since the very first season.
"I’ve always known," Collett explained. "And that’s actually kind of special, because it gave me something to look forward to. I obviously knew what they were going to do; I just didn’t know how big they were going to make it."
Collett expressed a profound sense of satisfaction with the execution of the death, noting that seeing the finished product—first on a laptop and then on the big screen—provided a surreal, emotional experience. He emphasized that the sequence was handled with the gravity it deserved, refusing to let the character’s exit feel like an afterthought. "What a way to go, ay?" he remarked. "It’s not just been brushed under the carpet—it’s really, really something."

The Tragedy Beyond the Prince: Justice for Vermax
While the death of a primary human character often dominates the discourse, Collett was quick to remind viewers that the loss of the bond between rider and dragon is equally, if not more, significant. The actor noted that the sound design for Vermax’s final moments was specifically engineered to elicit a visceral, empathetic response from the audience.
"The noises that it makes actually sound like a dog dying, which is really horrible," Collett said. "I don’t want anybody to just focus on Jace’s death this episode. We’ve lost a really good dragon as well, so people should take that into account."
This sentiment underscores a central theme of the A Song of Ice and Fire universe: the symbiotic, tragic relationship between the Targaryens and their dragons. As Collett pointed out, Jace and Vermax grew up together, making their simultaneous demise a reflection of the total loss of a soul, not just a soldier.
Behind the Scenes: The Stunts of the Gullet
The logistical complexity of filming a death scene that involves both an aerial dragon sequence and a drowning sequence required an immense amount of physical preparation. Collett revealed that he engaged in extensive horse-riding training to master the posture and movement required for the dragon-riding sequences.

When it came to the water, the production utilized an animatronic "buck" to simulate the sinking of the beast. Collett detailed the grueling process of being dragged into the water, noting that the reality of the filming environment was chaotic by design. "Loni [Peristere, the director] was on a megaphone the entire time screaming notes, which really helped immerse the [chaos] of this whole battle," he noted.
The actor’s commitment to his own stunts—practiced under the watchful eye of his stunt double—added a layer of authenticity that translated clearly to the screen. Despite the danger, Collett maintained a sense of humor about the process, joking about his insurance status now that his character has been written out of the show.
Implications for the Dance of the Dragons
The death of Jacaerys Velaryon is more than a plot point; it is a catalyst for total war. Throughout the first two seasons, Jace functioned as a voice of reason and a bridge between houses, often advocating for diplomacy and unity. His absence leaves a void in Rhaenyra’s inner circle that cannot be filled.
When asked about the impact on Rhaenyra’s mindset, Collett was definitive: "It’s going to change it completely. We’re going to get to see a different side to Rhaenyra that no one has ever seen before." He suggested that the death effectively "opened the floodgates" for the conflict, signaling a shift from the hesitancy that plagued the Blacks toward an era of unrestrained vengeance and chaos.

Furthermore, the act of Jace locking his mother in her room prior to the battle—an act of protective defiance—serves as a complex moral finality. While it could be interpreted as betrayal, Collett insists it was an act of pure, if misguided, love. Jace’s desire to step out of his mother’s shadow and prove his worth as a leader ultimately led to his demise, but it cemented his status as a tragic hero who lived and died trying to protect his family’s legacy.
A Young Actor’s Reflection: Growth and Gratitude
Reflecting on his tenure in the Game of Thrones universe, Collett described the experience as a life-altering chapter. Having grown up on set, the role allowed him to shed the "kid" archetypes he had been playing earlier in his career and step into a more mature, demanding narrative space.
"It’s a role that I was always waiting for," he said. The pressure of stepping into such a massive, lore-heavy franchise was significant, but Collett expressed gratitude for the opportunity to have contributed to the legacy of Westeros.
As for what he wished he could have done? The actor shared a lingering desire to have worked more closely with the "other side of the family"—the Greens—and admitted to a specific, unfulfilled ambition: "I wanted to kill someone. I really wanted to kill someone. Seeing Daemon do it all the time, that was an itch I wanted to scratch."

Conclusion
The death of Jacaerys Velaryon marks the end of an era for House of the Dragon. As the show moves forward into the heat of the war, the memory of the prince who died fighting for his mother’s throne will undoubtedly loom large. For Harry Collett, the journey has been an exercise in grace, professionalism, and, ultimately, a "good death" that will be remembered by fans for seasons to come. Whether Jace would have been a fair king or a feared one remains a point of speculation, but as the smoke clears over the Gullet, one thing is certain: the dance is far from over, and the cost of the crown has never been higher.
