Sam overhears Ebrose and several other maesters discussing a warning sent by Bran about the White Walkers' march on the Wall, and is dismayed by the maesters' skepticism. While reading the papers in Sam's quarters, Gilly discovers from a recently-deceased High Septon's journal that Rhaegar Targaryen had his marriage to Elia Martell annulled and married Lyanna Stark in secret, but Sam does not realize the significance of this information due to Gilly's having mispronounced Rhaegar. Annoyed at being unable to help in the battle against the White Walkers from the Citadel, Sam steals scrolls pertaining to the White Walkers and leaves Oldtown with Gilly and Little Sam.
