Stoneheart and the Brotherhood come across a small party led by Brienne, who informs Stoneheart that she is searching for Sansa at Jaime Lannister's request. Stoneheart names Brienne a traitor because she carries Oathkeeper, a Lannister sword that was forged from Ned Stark's Valyrian steel blade, Ice. Brienne swears that she is still faithful, but Stoneheart insists she must prove it by killing Jaime, whom she believes played a role in the Red Wedding. Brienne refuses, even when threatened with a hanging. Just before Brienne is to be hanged, she shouts out a word.
