Tyrion tells Daenerys that Varys has turned against her, and Drogon burns Varys for treason. Jon reaffirms his loyalty but cannot resume their intimacy; Daenerys declares that fear will have to secure her rule. Tyrion begs her to stop if the bells of King's Landing signal surrender. Learning that Jaime has been captured, he frees his brother and urges him to take Cersei away. Arya and the Hound meanwhile enter the Red Keep among the civilians sheltering there.
Daenerys attacks on Drogon, destroying Euron's fleet, the scorpions and the Golden Company. Her ground forces enter the city, and the outmatched Lannister soldiers drop their weapons. The bells ring, but Daenerys resumes the attack and burns streets filled with civilians. Grey Worm begins killing the surrendered soldiers, and Jon cannot stop the wider slaughter. Jaime fights Euron on the shore, killing him but suffering serious wounds. In the Red Keep, the Hound persuades Arya to abandon her revenge and escape.
Gregor kills Qyburn when he tries to prevent the brothers' fight, letting Cersei flee. Unable to kill Gregor with ordinary blows, the Hound tackles him through a wall and both fall into the fire. Jaime reaches Cersei and leads her below the keep, but their exit is blocked. They embrace as the building collapses on them. Arya struggles through the destruction, repeatedly losing the people she tries to help. Jon orders a retreat from the burning city. When Arya wakes amid ashes and bodies, she finds a white horse and rides away.
