Everything We Know About the Game of Thrones Season Finale

Going off the trailer, we know we will see a number of characters: Daenerys, Walder Frey and Jaime, the trials of Loras and Cersei, Davos confronting Melisandre, Jon and Sansa bonding, and Littlefinger creepin' on Sansa. But I think we can also assume we will see these characters, though they are not in the trailer: the Hound, Arya, and Brienne. It's possible we won't see this handful of characters until season seven, but based on their their season six arcs, it would be surprising if they were MIA in the finale.
