Tyrion searches for a champion after Cersei chooses Gregor Clegane to fight for the crown. Jaime refuses because he cannot defeat Gregor with his left hand. Bronn also declines, having accepted a wealthy marriage arranged through Cersei and fearing the Mountain's strength. Oberyn visits Tyrion and recalls Cersei's cruelty toward him as a baby. He agrees to fight, using the trial as his chance to avenge Elia and her children. At Castle Black, Thorne rejects Jon's suggestion to block the tunnel.
Brienne and Podrick meet Hot Pie at an inn. He tells them that Arya survived and traveled with the Hound, so they decide to search toward the Vale. Arya and the Hound encounter two attackers, one of whom bites the Hound before being killed. Arya kills the other after learning his name. The Hound later tells her how Gregor burned his face and their father concealed it. In Meereen, Daenerys sleeps with Daario and orders him to retake Yunkai.
Jorah persuades Daenerys to offer the masters a choice rather than simply kill them all; she sends Hizdahr to carry her terms. At the Eyrie, Sansa builds Winterfell from snow, then slaps Robin when he destroys it. Littlefinger kisses her, and Lysa sees them. Lysa later threatens to push Sansa through the Moon Door in a jealous rage. Littlefinger intervenes, reassures Lysa long enough to draw her away from Sansa, then says he only ever loved Catelyn and pushes Lysa to her death.
