House of the Dragon season 3 episode 1 ending explained: How that big death differs from Fire and Blood
In many ways, the Battle of the Gullet is when the Dance of Dragons shifts from a civil war into a full-on tragedy. Sure, there have been plenty of deaths already in House of the Dragon , like that of young Prince Lucerys Velaryon , who was killed by Aemond Targaryen and Vhagar. That incident fully ignited the war. The season 3 premiere of House of the Dragon however, opens with one of the biggest battles in Game of Thrones history — and it includes one of the franchise’s more heartbreaking deaths. source https://www.polygon.com/house-of-the-dragon-season-3-premiere-battle-of-the-gullet-death-ending/
