  ====Season 6====
  Brienne follows a group of Bolton soldiers sent to recapture Sansa, who had fled Winterfell along with Ramsay's slave Theon Greyjoy, and kills the soldiers before offering her services again to Sansa, who accepts. Brienne reveals to Sansa that Arya is still alive, although her whereabouts are unknown. Brienne, Podrick, and Sansa journey on to Castle Black (Theon having returned to the Iron Islands), where Sansa's half-brother Jon Snow, has just resigned as Lord Commander. At Castle Black she encounters Stannis' former advisors Davos Seaworth and Melisandre, and mockingly informs them that she killed Stannis and still blames them for their part in Renly's death. Also, a wilding, Tormund Giantsbane, takes a liking to Brienne, which she finds bothersome. Brienne escorts Sansa to meet with Littlefinger, who reveals that Sansa's great-uncle Brynden "Blackfish" Tully has captured House Tully's home Riverrun from the Freys. When Jon and Sansa leave Castle Black to gather men to overthrow Ramsay Bolton, Sansa sends Brienne to Riverrun to seek the Blackfish's support. Brienne claims Davos can't be trusted due to his former support for Stannis and then abandoning him, even though Davos only left on Stannis' orders.
  Brienne arrives at Riverrun to find it besieged by the Frey and Lannister armies, led by Jaime. Jaime permits Brienne to enter Riverrun to talk to the Blackfish, who is sympathetic to Sansa's cause but refuses to abandon his home. Soon afterward, the Blackfish's nephew Lord Edmure Tully is coerced into ordering the Tully troops to stand down. As the Lannisters begin pouring into the castle, the Blackfish helps Brienne and Podrick escape. Jaime sees them sailing away, and he and Brienne exchange a mournful farewell.
