re: Sansa becoming a b*tch....yeah I said it

But Sansa is in the unique position to appeal to both sides. She's the widow of the Lord of Winterfell and Warden of the North (and maybe with his child, but that's a theory for another day) and the eldest true born child of the previous Lord of Winterfell and Warden of the North (not counting Roose). Since no one has any idea that Bran's still alive, she's got the best claim to the North of anyone...just as Littlefinger knew long before any of this went down.
