The upcoming third season of the HBO original series House of the Dragon is set to break a franchise record established throughout the combined history of the Game of Thrones universe. Actors Bethany Antonia and Harry Collett, who portray Baela Targaryen and Jacaerys “Jace” Velaryon respectively, have confirmed that their characters will become the first couple in the history of the televised franchise to engage in a major battle together onscreen. This milestone will take place during the highly anticipated Battle of the Gullet, a pivotal naval and aerial conflict scheduled to serve as the centerpiece of the Season 3 premiere.
The revelation came during a press appearance at the 2026 ATX TV Festival in Austin, Texas, where the primary cast members representing the “Black” faction of the Targaryen civil war gathered to discuss the production’s trajectory. Alongside Antonia and Collett were Steve Toussaint, who plays Lord Corlys Velaryon, and Abubakar Salim, who portrays Alyn of Hull. The group provided insights into the scale of the upcoming season, which is expected to address the mounting tensions following the conclusion of the second season’s blockade of King’s Landing.
Strategic Context and the Prelude to the Battle of the Gullet
The Battle of the Gullet is a foundational event in the "Dance of the Dragons," the internecine conflict described in George R.R. Martin’s Fire & Blood. Within the narrative of the television series, the battle serves as the Greens’ primary attempt to break the Velaryon blockade that has throttled the economy of King’s Landing and starved the city’s population. To counter the naval dominance of the Blacks, the Green Council—led by Ser Otto Hightower and later Aemond Targaryen—forms an alliance with the Triarchy, a powerful confederation of the Free Cities of Myr, Lys, and Tyrosh.
As Season 2 concluded, the mobilization of the Triarchy fleet was signaled, setting the stage for a massive confrontation at sea. The Gullet, the narrow stretch of water between Dragonstone and the mainland, becomes the primary theater of war. For Queen Rhaenyra Targaryen, the defense of this channel is critical; its loss would not only lift the siege on the capital but also leave Dragonstone vulnerable to a direct maritime invasion.
The Role of Jacaerys Velaryon and Baela Targaryen
The partnership between Jacaerys Velaryon and Baela Targaryen represents more than a romantic union; it is a political and military alliance designed to secure the succession of Rhaenyra’s line. Jacaerys, as the Prince of Dragonstone and heir to the Iron Throne, rides the dragon Vermax. Vermax is a maturing dragon, noted for its agility and growing ferocity, which will be tested against the sheer volume of the Triarchy’s naval vessels.
Baela Targaryen, the daughter of Prince Daemon Targaryen and Lady Laena Velaryon, rides Moondancer, a slender and exceptionally fast dragon. While Moondancer is smaller than some of the older dragons in the Targaryen arsenal, her speed provides a tactical advantage in the chaotic, smoke-filled environment of a naval engagement.
According to statements made by Antonia and Collett at the ATX TV Festival, the coordination between Vermax and Moondancer marks the first time the franchise has showcased a synchronized dragon-led assault by a betrothed or married couple. While Daenerys Targaryen and Jon Snow rode dragons simultaneously in Game of Thrones, their aerial interactions were primarily focused on travel or disorganized skirmishes against the Night King, rather than a structured tactical strike against a conventional military force.
Naval Command: Corlys Velaryon and Alyn of Hull
While the aerial assault is spearheaded by the younger generation, the surface-level conflict remains under the command of Lord Corlys Velaryon, the "Sea Snake." Steve Toussaint’s character enters Season 3 as a man grappling with the loss of his wife, Princess Rhaenys, and the weight of his legacy. The Battle of the Gullet serves as a critical test for the Velaryon fleet, which has long been the backbone of Rhaenyra’s military power.
A significant development in the upcoming season is the integration of Alyn of Hull into the Velaryon command structure. Played by Abubakar Salim, Alyn is one of the "Dragonseeds"—bastards of Valyrian descent—who has been acknowledged for his maritime prowess. The relationship between Corlys and Alyn, and by extension Alyn’s brother Addam (the new rider of the dragon Seasmoke), adds a layer of familial complexity to the military operation. At the ATX Festival, Salim noted that the naval sequences involve a high degree of practical effects combined with digital enhancements to simulate the scale of the Triarchy’s "Sharps" (warships).
Chronology of the Conflict: From Season 2 to Season 3
The timeline leading to the Battle of the Gullet has been meticulously paced by showrunner Ryan Condal.
- The Blockade (Season 2): Lord Corlys establishes a total maritime blockade of the Gullet, leading to riots and starvation in King’s Landing.
- The Sowing of the Seeds (Late Season 2): Rhaenyra and Jacaerys successfully recruit new dragon riders for Vermithor, Silverwing, and Seasmoke, significantly increasing their aerial superiority.
- The Triarchy Alliance: The Greens negotiate with the Triarchy to send their fleet to break the blockade in exchange for territorial concessions in the Stepstones.
- The Engagement (Season 3 Premiere): The Triarchy fleet enters the Gullet, prompting an immediate response from Dragonstone.
Production data indicates that the Battle of the Gullet was originally considered for the Season 2 finale but was moved to the Season 3 premiere to ensure the sequence received the necessary budget and screen time. This decision allows the production to dedicate a significant portion of the episode to the tactical maneuvers of the dragons and the brutal reality of naval warfare in the 14th-century-inspired setting.
Production Scale and Technical Specifications
HBO has reportedly increased the per-episode budget for Season 3 to accommodate the technical requirements of the Battle of the Gullet. This sequence involves:
- Digital Asset Management: The creation of dozens of unique Triarchy ship models, each reflecting the distinct aesthetics of the three Free Cities.
- Advanced Simulation: High-fidelity water and fire simulations to depict the destruction caused by dragonfire on the open sea.
- Aerial Choreography: Use of the "The Volume" (LED stage technology) and mechanical gimbals to capture the performances of Antonia and Collett as they navigate the simulated skies.
The Battle of the Gullet is historically significant in the lore for being one of the bloodiest engagements in Westerosi history. Unlike the land-based Battle of Rook’s Rest seen in Season 2, the Gullet is a multi-front conflict involving thousands of sailors and multiple dragon riders.
Implications for the Broader Narrative
The outcome of the Battle of the Gullet will have immediate and long-lasting implications for the power dynamics of the Seven Kingdoms. For the Blacks, the battle is a defensive necessity. However, the cost of victory or the sting of defeat will influence the psychological state of Queen Rhaenyra.
Analysis of the source material suggests that this battle is a turning point for Jacaerys Velaryon. As he steps into a leadership role, his decisions in the heat of combat will define his reputation as a future king. The inclusion of Baela Targaryen as his wing-rider reinforces the theme of "the dragon has three heads" and the necessity of Targaryen unity.
Furthermore, the battle serves as a litmus test for the "Dragonseeds." While Vermax and Moondancer are ridden by high-born Targaryens, the presence of the newly claimed dragons in the reserve or the periphery of the battle introduces a volatile element. The loyalty and discipline of these new riders remain a central concern for Jacaerys, who has expressed reservations about elevating those of low birth to the status of dragon riders.
Conclusion and Industry Impact
The announcement that Baela and Jace will fight together has generated significant discussion within the television industry regarding the evolution of character dynamics in high-fantasy epics. By placing a romantic pair in the vanguard of a catastrophic military engagement, the series aims to heighten the emotional stakes of the spectacle.
As House of the Dragon enters its third season, the transition from political maneuvering to total war is complete. The Battle of the Gullet stands as a testament to the show’s commitment to large-scale storytelling, utilizing the relationship between Baela Targaryen and Jacaerys Velaryon to ground the fantastical elements of dragon warfare in human stakes. With the premiere scheduled for 2026, the production continues to be a benchmark for the capabilities of modern television production, blending historical-inspired naval tactics with the unique demands of a dragon-centric conflict.
