Yara Greyjoy arrives at Winterfell to bring Theon back to Pyke, after his botched attempt to recapture the Stark boys.

In King's Landing, Cersei Lannister attempts to blackmail Tyrion by abducting the prostitute, Ros, whom Cersei believes to be his secret lover. The capital prepares for assault by Stannis, who, underway to King's Landing, promises to make Davos Seaworth his Hand of the King.

In Qarth, Jorah Mormont agrees to accompany Daenerys into the House of the Undying to retrieve her dragons.
