when Ned was talking to Arya back in season 1 about how she'd be a princess or Lady or whatever the fuck, she was all, "That's not me." She knew that wasn't her path. When she met her direwolf again, she was all "Come with me!" Wolf was all, 'That's not me.' Except direwolves don't talk, so Arya had to say it. The wolf has its own life now. Wouldn;t be shocked to see it again, tho.
