News that Aegon and Sunfyre are alive sends Rhaenyra into a panic. Daemon urges her to answer with strength, and she orders him against the Hightowers at Tumbleton. Baela challenges her failure to rescue Corlys, while Rhaenyra dismisses Mysaria and demands the High Septon's public blessing. At Harrenhal, Alys saves Aemond from Alicent's poison and tells him about her long imprisonment there. Aegon arrives alive and orders his brother to help recover the throne.
Gwayne brings Corlys to Daemon and tries to negotiate peace before Tumbleton is attacked, but Daemon rejects the proposed compromise. The Winter Wolves enter the town, and Caraxes opens its gates with fire. Ulf finally mounts Silverwing and attacks Rhaenyra's troops, then turns his flames on the Hightower forces as well. Ormund dies in the destruction. Corlys pulls Daemon away from the lost town, and Hugh finds that his wife has been killed in the burning.
In King's Landing, Rhaenyra forces Helaena to eat despite her resistance, treating the pregnant queen as a captive whose health she can command. At the Great Sept, the High Septon again refuses to anoint her, and Alyn kills him on her orders. Rhaenyra declares herself the promised prince before the crowd. Returning to the Red Keep, she learns that Helaena has died by suicide. Helaena's embroidery depicts both her own death and the flames surrounding Rhaenyra's reign.
