S3E8 · The Treasons at Tumbleton

Complete story — includes the ending

After learning that Aegon is alive, Rhaenyra becomes more ruthless. She detains Baela, dismisses Mysaria, and has a despondent Helaena force-fed. Rhaenyra has Alyn kill the High Septon after he refuses to anoint her and tells the smallfolk of Aegon the Conqueror's dream, stating that she is prophesied to rule. Alys informs Aemond that she became cursed with immortality after failing to save her dying son with magic. Aegon tells a remorseful Aemond to find Vhagar and help retake the Iron Throne. With the Tully army outside Tumbleton, Ormund lines the ramparts with children to dissuade Daemon from using Caraxes. Daeron and Gwayne free Corlys before negotiating with Daemon to divide the realm, but he refuses. Ormund finds Ulf hungover and beats him. Roderick's Winter Wolves scale Tumbleton's walls while Caraxes destroys the main gate. Ulf mounts Silverwing and attacks the Tully forces before burning Tumbleton, killing Ormund and Roderick while they fight. Jon duels Daemon, but Ulf's attack interrupts them. Corlys convinces Daemon to retreat. Gwayne cannot find Daeron while Hugh finds Kat dead. Rhaenyra learns that Helaena jumped from a window to her death, leaving a tapestry showing Rhaenyra on the Iron Throne surrounded by fire and blood.
