I don't think you guys are getting deep enough into the game though. They want to 'out' LF, but Bran's word ain't going to be good enough to the Lords of the Vale.
They need the Vale's Knights/heavy horse.
If Arya just kills LF, they lose the Vale.
If they out LF, then the Vale guys line up to carve a chunk out of Petr.
