Ramsay hunts a woman with Myranda and his hounds while Theon, now called Reek, follows obediently. Roose arrives at the Dreadfort and criticizes Ramsay for ruining Theon's value as a hostage.

Beyond the Wall, Bran touches a weirwood and sees visions directing him farther north.
At Dragonstone, Melisandre burns prisoners, including Selyse's brother, as offerings to the Lord of Light. In King's Landing, Jaime begins practicing swordplay with Bronn using his left hand. Warned that Cersei knows about Shae, Tyrion insults Shae to make her leave and orders Bronn to put her on a ship. Joffrey receives gifts for his wedding and uses his new sword to cut apart the book Tyrion gives him. He and Margaery then marry before the court.
At the wedding feast, Joffrey stages a mocking version of the War of the Five Kings with dwarf performers, humiliating Tyrion and upsetting Sansa. When Tyrion refuses to join the performance, Joffrey pours wine over him and makes him serve as cupbearer. After drinking and eating wedding pie, Joffrey begins choking and collapses. Dontos urges Sansa to flee with him during the confusion. Joffrey dies in Cersei's arms, pointing toward Tyrion, and Cersei orders her brother arrested for the murder.
