Daenerys sends the sea snakes on Yara's fleet to gather the forces of Dorne, sends the Unsullied to attack Casterly Rock and plans a siege of King's Landing. She has a heart-to-heart with Varys, warning him to be more honest and loyal than he has proved to past Kings.  Melisandre shows up to pitch her flexible prophecy. Grey Worm and Missandei share a touching, and naked, farewell. Cersei tries to woo the bannermen of Highgarden to her side to repel the foreign invaders. Qyburn invents the ballista. Arya visits Hot Pie and discovers that Jon is King in the North. Jon leaves for Dragonstone in hopes of getting Daenerys's support against the White Walkers, and access to the Dragonglass mine.  He leaves Sansa in charge after punching Littlefinger in the dick. Sam performs a gross and painful grayscalectomy on Jorah.  Brutal pirate action on the high seas when Euron's fleet attacks Yara's, and we're treated to a thrilling sequence that wipes several more players off the board.
