Originally i thought Tyrion was gonna get his but i kinda feel they will wait until next season. I kinda feel they will speed up Jon Snow getting the lord commander so they can speed up Samwell's journey the beginning of next season. I probably see the hound getting put down in the finale as well. other than that i can't think of much else, they will advance Bronn some but i honestly can't remember where he goes next. Think Sansa is pretty much done for the season as well. Obviously next week will be almost entirely the wall so we will see Stannis ride in to save the day so they will advance that a bit.
