Where do you think the show is heading? Random musings on how I think it might unfold:
The wall.......... What purpose doe's the wall and nights watch serve if the NK is defeated? Or do they just battle him to another 1,000 year retreat? With the wall down, and the wildlings South of the Wall, I don't see a need for the NW. Rather, I see an 8th kingdom, originally led by Tormund, north of the wall, and an ally of the North. If Jon wanted to get away from all the politics of the South, and pretty much disappear after the war, this might not be a bad place for him.
Theon, I imagine he saves Yara, dies in the process, and she ends up ruling the Iron Islands.
Jamie killing Cerise, while entirely possible, just seems too predictable. The prophecy by Maggie seems to imply the killer will choke Cersei to death, using his/her hands (special attention to the plural). Jamie only has one hand. And this doesn't seem to be Arya's style of killing either. If D & D are going to set up an " I didn't see that one coming" moment, I think this is the spot.
While Cleagenbowl is just fan service, and the Hound never speaks of a desire to kill his older brother, the Hound killing Cersei while in the Mountains armor might fulfill the prophecy in an unexpected way?
Vary's? who knows, he could die of old age and as long as in Westeros, this fulfills Mel's premonitions.
I do think Jorah's honor will be restored, and if the Nights Watch is still around, that is a good ending (him taking his fathers place), just not sure it will be. If Jorah and Jon become good friends, and Jorah yielding to Jon for Dany's affection, I think Sansa is a good match for Jorah.
Will we ever see Sweet Robynn again? What happens to the Vale? A Sansa/Sweet Robyn marriage is just to ewwww........ but Sansa ending up with the Vale is interesting............(assuming Jon lives of course)
Ultimately Bronn's fate will rely on if he chooses to stay with Cersei after/if Jamie leaves. I hope he defects as well, one of my favorite characters.
Gendry will be the king, with Arya as his queen. Brienne end up in charge of the kings guard, and Davos the ship master.
Bran is the NK theory: I really hope he doesn't end up being the NK, although I am starting to see this as a possible outcome (as much as I hate it). For Brann to die however, I think it has to coincide with the death of all magic, aka no more dragons, no more Others, no more Wall, etc.
Tormund is a key figure in the show universe, as there are no other named characters to represent the Wildlings at this point. For him to die, it would have to be fairly late in next season, and a good chance he survives as I stated earlier. The other minor characters are all cannon fodder in my opinion, with the possible exception of Qyburn.
Qyburn has been a bit of an enigma to me, I really like his character, and I compare him to Bronn in many ways. While both are on the wrong side, both are more opportunists than inherently good or bad. Bronn sells his services to the highest bidder, and Qyburn chooses to ally with those that allow him to conduct his research in the manor he sees fit (remember he was kicked out of the Citadel because his experiments were too dark). It will be interesting to see his reaction to the wights, and if his curiosity to see what makes them tick, ultimately ends up with his departure from Team Cersei. With the Citadel all but turning their backs on the WW issue, I think it would be a nice turn of events to see Sam, Brann, Gendry, and Qyburn working together to make weapons to fight the WW's.
As to who kills the NK, right now my leading characters are......Jon, Jamie, or Beric. Or a combination of all three. I sincerely believe Jamie is the third head of the dragon, and will lead a force from Westeros to ally with the Northern forces and Dany's forces to help fight the great battle.
