S4E10 · The Children

Complete story — includes the ending

Jon's meeting with Mance Rayder abruptly ends when Stannis and his army overrun the Wildling camp, taking Mance prisoner. Bran finds the weirwood tree from his visions but wights attack the group, killing Jojen. A Child of the Forest saves the others and takes them to the Three-Eyed Raven, revealed to be an old man encased within tree roots inside a secure cave. In the Vale, Brienne and Podrick encounter Arya and the Hound. A misunderstanding leads to the Hound and Brienne having a duel; which ends with Brienne pushing the Hound off a cliff. The Hound, grievously wounded, begs Arya to kill him, but she takes his money and leaves him for dead. She boards a ship headed to Braavos to find Jaqen H'ghar. In King's Landing, Cersei orders Qyburn to save the life of the Mountain, who was poisoned by Oberyn's blade. Jaime releases Tyrion from prison, but before escaping the city, Tyrion finds Shae in Tywin's bed and fatally strangles her. He confronts and kills Tywin on the privy with a crossbow, then is smuggled aboard a ship by Varys. In Meereen, a citizen brings Daenerys his daughter's charred remains, burned by dragon fire. Realising they are too dangerous to remain free, Daenerys chains Rhaegal and Viserion in the catacombs, however Drogon cannot be found.
