it was silly to charge the Dragon; while heroic .... it may have still resulted in the death of him and whomever it was that saved him. I truly cannot see Jamie partnering up with the North to fight the white walkers; can't see Cersei participating in that either for some odd reason. I think Arya takes her out; possibly the Mountain too. she's a well trained Assassin with a real vendetta. The North is focused on the north; i think she'll help take the south out so everyone can focus on the real threat at hand. Unless Tyrion re-starts the family, House Lannister will be done :) (in my opinion of course!)

I also loved all of Tyrion's commentary this season; especially during that charge ---
