Daenerys meets with the slave masters to negotiate terms of surrender, but they refuse it. Riding Drogon, as Rhaegal and Viserion assist, Daenerys attacks and burns the slavers' fleet. Grey Worm kills two of the masters, leaving one to tell of what he had witnessed. After the battle, Theon and Yara meet with Daenerys and Tyrion and agree to an alliance. Near Winterfell, the Stark and Bolton armies meet on the field. Ramsay feigns setting Rickon free, but kills him with a long-distance arrow before Jon can save him. In the battle, the Stark forces are pinned by Bolton soldiers, but are rescued by the Knights of the Vale. Ramsay flees inside Winterfell, but the Wildling giant Wun Wun, having taken numerous arrows to his body, manages to break down the gate before succumbing to his wounds. Jon brutally beats Ramsay and takes him prisoner. Sansa later visits Ramsay's cell in the kennels and watches as his starving hounds devour him.
