In a flashback, a witch tells a teenage Cersei that someone younger and more beautiful than herself will one day steal her accomplishments. In the present, Tywin is buried and Lancel returns, now a devoutly religious man and a member of the "Sparrows". In Pentos, a despondent Tyrion agrees to accompany Varys to Meereen to support Daenerys's claim on the Iron Throne. In Meereen, the insurgent "Sons of the Harpy" murder an Unsullied, forcing Daenerys to launch more restrictive measures without respecting the old traditions. Missandei gets suspicious when she realizes that the Unsullied visit brothels. Daenerys's locked-away dragons attack her when she checks on them. In the Vale, Baelish puts Robin in the care of House Royce and leaves with Sansa. At the Wall, Stannis seeks to enlist the Wildlings in his war against Roose. Jon Snow is unable to convince Rayder to accept Stannis's authority. When the latter has Mance burned alive, Jon Snow ends his suffering with an arrow to the heart.
