Previously on Game of Thrones: Theon led a raid on a town very close to Winterfell. Cate, Stannis, and Arya all got some fairly badass sidekicks, and Daenerys received a tempting proposal.
Chaos at Winterfell. Luwin rushes to his room, where he has just enough time to dash off a quick note and tie it to a raven before soldiers burst in and catch him. Theon, meanwhile, arrives at Bran’s room and informs him he’s captured the castle, which confuses the hell out of Bran, because he hasn’t been reading Theon’s status updates lately and can’t keep up with his changing allegiances. Theon tells Bran he’ll have to give in publicly, which Bran doesn’t want to do, but Theon tells him that, if he doesn’t, he’ll start hurting people in the castle. Before Theon goes, Bran asks him if he hated the Starks the whole time.
