Here's Exactly Who Knows About Jon Snow's Secret on Game of Thrones — and Why It Matters

Arya learns the truth about Jon along with her older sister. We don't get to see her reaction to the news, but it's fair to assume she was pretty shocked. The next time we see Arya, she's leaving Winterfell on horseback and joining the Hound on the journey to King's Landing. We're not sure what the young Stark is up to, but she says she has some unfinished business. Could it have to do with the recent revelation, or is Arya just looking to cross another big name off her list?
