Worst season of the show so far, minus episode 8. I also don't think for a second Jon is dead. Mellisandre being at the wall is too convenient.
Longshot prediction. At the wall, they place Jon's body on a funeral pyre and light it. Miraculously, he arises from the flames, unburnt. Camera slowly focuses on a shadowy figure in the background to reveal Mel standing there chanting some witch magic nonsense. Reborn in fire with his Targareyn blood, and to lead the living against the White Walkers.
