What I meant was that Littlefinger can keep Robin under control, and brat or not he is an Arryn. And without House Arryn the Vale will go into a succession crisis. Sansa needs to control Robin in order for House Arryn to survive. As for the Vale Lords and Jon, I have another theory for that for a later thread.
