  ===''A Clash of Kings''===
  Tyrion makes several attempts to free Jaime, first by having disguised Lannister guards attempt to break him out and then by offering to swap Arya and Sansa Stark for Jaime. After hearing of the supposed deaths of Bran and Rickon Stark, Catelyn interrogates Jaime. Jaime admits to pushing Bran out the tower window, to his incest with Cersei and to fathering her children. Jaime then mocks Ned for having tarnished his own honour by fathering a bastard, prompting Catelyn to call her bodyguard Brienne of Tarth for her sword.
