  ====Season 7====
  Jon travels to Dragonstone to negotiate with Daenerys Targaryen for her support against the White Walkers, leaving Sansa as regent in his absence. Soon after, Bran and Arya return to Winterfell. Littlefinger seeks to drive a wedge between Sansa and Arya by letting Arya find Sansa's letter to Robb asking him to bend the knee to Joffrey, causing Arya to confront Sansa. Sansa sneaks into Arya's quarters and comes across the "faces" Arya has taken from the various people she has killed on her travels; Arya catches Sansa and tells Sansa of her ability to assume people's identities with the faces before she threatens her.
  Sansa later receives an invitation to King's Landing, where Jon intends to present Cersei, who is now Queen of the Seven Kingdoms, with proof of the White Walkers' existence. Refusing to return to King's Landing, she sends Brienne as her representative.
  Sansa shows Littlefinger the letter she received from Jon following the meeting in King's Landing, in which Jon states that he had pledged his support to Daenerys Targaryen. Littlefinger continues his manipulation of Sansa by claiming that Jon has betrayed the North, Sansa should seize power from Jon, and suggests Arya intends to murder her to become Lady of Winterfell. Sansa summons Arya to the great hall and begins an accusation of treason and murder, before directing the accusation towards Littlefinger. With help from their brother Bran (now known as Three-Eyed Raven), Sansa and Arya reveal that they are aware of Baelish's numerous crimes, including the murder of Lysa Arryn, orchestrating the murders of both Jon Arryn and Eddard Stark, and manipulating the Starks and Lannisters to war. Baelish tries to plead for his life, but Sansa refuses and sentences Littlefinger to death. Arya executes him. The Stark sisters later resolve their differences and acknowledge that the Starks must stand together to survive the winter. They remember their father telling them, "The lone wolf dies, but the pack survives."
