Daenerys heeds Tyrion's plan for the conquest of Westeros: rather than taking King's Landing by force and killing thousands, Yara's fleet will carry the Dornish army to besiege the capital alongside the Tyrell forces while the Unsullied take Casterly Rock. Daenerys challenges Varys's loyalty, threatening to burn him alive if he ever betrays her, and receives an unexpected visitor in Melisandre, who encourages her to invite Jon Snow to Dragonstone, calling him integral to the war. Grey Worm and Missandei consummate their relationship. Cersei summons several lords, demanding their fealty, and Jaime offers to elevate Randyll Tarly as Warden of the South; Qyburn shows Cersei a prototype ballista capable of killing dragons.
Arya is reunited with Hot Pie, who tells her the Boltons are dead and Jon is now King in the North; she resets course for Winterfell. Though the decision stirs a revolt of opinion, Jon sails for Dragonstone to request Daenerys's help against the White Walkers, leaving Sansa in charge at Winterfell and warning Littlefinger never to touch her. Sam performs a forbidden surgery on Jorah's greyscale infection. Euron's fleet ambushes Yara's, killing Obara and Nymeria and capturing Ellaria, Tyene and Yara; Theon, gripped by flashbacks of his time as Reek, jumps overboard.
