At sea, Littlefinger admits to Sansa that he was involved in Joffrey’s death. In King’s Landing, Olenna, who is planning to leave, also implies to Margaery that she was involved in the poisoning and convinces her to seduce Tommen before Cersei has a chance to turn him against her. Jaime meets with Tyrion and is convinced of his innocence. However, Cersei is adamant about Tyrion’s guilt and orders Jaime to hunt down and kill Sansa. Jaime instead tasks Brienne with finding and protecting her, giving her both his Valyrian sword and Podrick as her squire. In the North, in an effort to get rid of Jon, Alliser Thorne and Janos Slynt conspire to allow Jon to lead an expedition against the mutineers, who have captured Bran’s party and forced him to reveal his identity. Further north, a White Walker takes Craster’s last newborn son to a secret ritual site, where he is transformed into a Walker.
