Sansa kills Littlefinger, Arya takes his face and continues his role to keep his army (and the actor) around.
I think Danny still has a connection to the dragon when they meet again. Or maybe the other dragons to it.
I know you know this now, but they were just doing it for LFs benefit. It was alluded to in the reveal last night that they had a heart to heart and each of them knows what the other went through after they were separated.
Here's a few lingering questions I have: 1. Where will Jaime go? As cold a bitch as Cersei is, it's hard to imagine that she basically pushes away her last and most important ally. She may be a black hearted cunt, but she's not stupid and letting him leave was stupid. 2. Will Bronn stay in King's Landing now that Jaime is gone? Cersei probably promotes him to commander of the Lannister army 3. Isn't Sam still a member of the Night's Watch? Could he be seen as a deserter leaving the Citadel and not going back to Castle Black? 4. This question goes back a ways, but did anyone find it odd that Randall Tarly never tried to get his Valerian steel swordback from Sam? The quickest way to end the conflict in Westeros is to have Arya put Little Finger's face on, then set up a meeting with Cersei and kill her. Of course, she'd have to deal with The Mountain, but maybe have The Hound accompany her, which would be a perfect segue to the Clegane Bowl. I don't think this will happen, mostly because the popular theory seems to be that Jaime will kill her to fulfill the valonqar prophecy.
