  ===At Winterfell===
  Arya confronts Sansa about the letter Sansa wrote to persuade Robb to bend the knee to Joffrey. Arya accuses Sansa of mainly being concerned that she will lose face with the Northern lords if the letter is made public. Sansa confides in Littlefinger, who suggests that Brienne, sworn to serve both sisters, would intervene if Arya acted against Sansa. However, when Cersei invites Sansa to King's Landing to parley, Sansa sends Brienne as her representative. Sansa searches Arya's room and finds Arya's faces. Arya discovers Sansa and explains her training with the Faceless Men. Arya says she could take Sansa's face, seemingly threatening her with the Valyrian steel dagger before instead leaving her with it.
