The third season premiere of HBO’s “House of the Dragon” opens with the “Battle of the Gullet,” a large naval clash that results in multiple deaths and major losses for the characters aligned with Rhaenyra Targaryen (Emma D’Arcy). Several outlets report that Rhaenyra’s eldest son, Jacaerys “Jace” Velaryon, is killed during the battle, along with his dragon, Vermax, in the fighting. The premiere also includes other reported fatalities connected to the conflict, including Sharako Lohar. Corlys Velaryon is described as being severely weakened, and Tyland Lannister is reported as presumed lost at sea. In coverage that includes interviews and actor reaction, the show’s cast discusses how the character exits are handled, with attention on how the deaths play out on screen and how they land emotionally for the principal characters. The reporting also notes that the episode is available for streaming and continues through subsequent scheduled airings, with viewers set to see how Rhaenyra responds to the loss of her son as the season moves forward.
