Jon Snow treats with Mance Rayder, but their negotiations are interrupted when Stannis Baratheon and his army suddenly overrun the wildling army and take Mance prisoner. Later, the Night's Watch burn the bodies of their dead while Jon burns Ygritte beyond the wall. Bran and his party come upon the large Heart Tree from his visions, but as they arrive they are attacked by wights; though Jojen is killed, Bran, Hodor and Meera are saved by a child of the forest who takes them to the three-eyed raven. In Meereen, Daenerys reluctantly grants a former slave's wish of being sold into slavery again. The next citizen brings her the charred remains of his daughter who was burned by one of her dragons. As a precaution, Daenerys chains her other dragons in the catacombs. In the Vale, Brienne and Podrick come upon Arya and the Hound. Brienne mortally wounds the Hound, while Arya escapes. With the coin Jaqen H'ghar gave her, Arya buys passage on a ship bound for Braavos. Meanwhile in King's Landing, Cersei orders Qyburn to do anything to save the Mountain. She confronts her father, threatening to reveal her and Jaime's incestuous affairs if she is forced to marry Loras. Tyrion is released from his cell by Jaime, but he later finds Shae in Tywin's bed and kills her. He then confronts his father in the privy and shoots him with a crossbow, before escaping the city with Varys.
