  ====Season 7====
  Taking the face of Walder Frey, Arya gathers the men of House Frey for a feast before killing them all with poisoned wine. Arya then journeys south, intending to travel to King's Landing to assassinate Cersei (now Queen of the Seven Kingdoms following the extinction of House Baratheon). However, Arya changes her mind after learning from Hot Pie that Jon has ousted House Bolton from Winterfell and has been crowned King in the North, and decides to return to her ancestral home. Along the way she encounters a wolf pack led by her long-lost direwolf Nymeria. Nymeria recognizes Arya, but she has grown feral and ignores Arya when she asks her to come North with her.
  Arriving at Winterfell, Arya finds that Jon has traveled to Dragonstone but is reunited with Sansa and Bran. Bran reveals his knowledge of Arya's kill list through greenseeing and presents her with a Valyrian steel dagger, which had been given to him by Littlefinger. Arya is also reunited with Brienne, who continues to serve the Starks, and manages to equal the female warrior during sparring despite her smaller size.
  Littlefinger seeks to increase his influence on Sansa by driving a wedge between the Stark sisters. To this end, he allows Arya to witness him receiving a confidential message obtained from Maester Luwin's records. Arya breaks into Littlefinger's quarters to steal the message, which is a plea sent by Sansa following Ned's imprisonment to Robb imploring him to bend the knee to Joffrey. Outraged, Arya confronts Sansa and is unconvinced by her explanation that she did so to try and save Ned's life. Later, Arya catches Sansa looking at her collection of faces and threatens Sansa before leaving. Some time later, Sansa summons Arya to the great hall and begins an accusation of treason and murder; however, the accusation is directed towards Littlefinger, whose crimes have been discovered by Bran's greenseeing. Despite Littlefinger's pleas for mercy, Sansa sentences Littlefinger to death and Arya cuts his throat with the Valyrian steel dagger. The Stark sisters later resolve their differences, and acknowledge that the Starks must stay together to survive winter.
