The Arya storyline is the only intriguing part of S6 so far. Everything else is just puzzle pieces falling into place, but I have no idea what she's being set up to do.
My best guess is she will assassinate either Ramsay or The Warrior Formerly Known As The Mountain (or both).
Not really sure how you can be sure what the hell role Bran will be set to do and what impact he may have on Westeros. He's obviously the most powerful Stark still alive and I doubt he will only serve to give us flashbacks.
Well one of them did just come back to life....
Presumably due to the Red God, not because of his own power. Outside of brooding looks and being entirely too sensitive and nice to Sam, what "power" can you really attribute to Jon Snow. Obvz he
could be a dragon rider/targaryan/savior of westeros, but at present, Bran is just warging with little giants, time traveling, and, presumably, watching the entire world.
