Roose Bolton returns to the Dreadfort to meet up with his bastard son Ramsay Snow and sees first hand how Theon Greyjoy has been brutalized into a subservient persona, called 'Reek'. His next objective is to find and kill the remaining Stark children — Bran and Rickon, who threaten the legitimacy of his new title as well as reclaiming the territories under Ironborn occupation. Beyond the Wall, the visions of the Three-eyed Raven compel Bran and his companions to travel further northwards, despite growing hunger. At Dragonstone, Melisandre orders several people to be burned as a tribute to the Lord of Light, to the delight of Queen Selyse and the disgust of Davos and Shireen. In King's Landing, Tyrion breaks up with Shae to protect her from his family and arranges for her to be shipped off to Pentos. Jaime begins discreetly training his left-handed swordplay with the help of Bronn. Later at the Royal Wedding feast, tensions fly high between Joffrey and Tyrion. The feast is abruptly cut short when Joffrey succumbs to poisoned wine and dies. A grief-stricken Cersei accuses Tyrion of murdering the king and orders his arrest.
