S4E7 · Mockingbird

Complete story — includes the ending

Cersei appoints Ser Gregor Clegane, the Mountain, as the champion for the prosecution in Tyrion's upcoming trial by combat. Jaime and Bronn decline to fight the Mountain for Tyrion, but Oberyn accepts. He seeks to avenge his sister, Elia's rape and murder by the Mountain during Robert's Rebellion. Daenerys takes Daario as her lover, then sends him to handle the resurgent slavers in Yunkai. Melisandre and Selyse prepare to depart Dragonstone, intending to take Shireen with them. As the Wildlings approach Castle Black, Alliser Thorne rejects Jon's suggestion that they seal the tunnel. At an inn, Brienne and Podrick meet Hot Pie, who updates them about Arya. They resolve to travel to the Vale, deducing that she would seek shelter from her aunt. In the Vale, Lysa witnesses Littlefinger kissing Sansa. Enraged, she threatens to throw Sansa through the Moon Door, a circular opening in the floor with a steep drop to rocks below; Littlefinger intervenes and, after admitting to Lysa that he always loved her sister Catelyn rather than her, shoves Lysa to her death.
