First off I was well confused with your Aegon comments. He's still John to me lol
Ash - I think your right about the dragons and who kills who and riding who
Defo with John killing the night King
I think your both kinda right about the mountain, hound and Jamie and would be awesome if the hound uses a fire sword but I'm not sure if he poses that power. Saying that he sees visions in the fire that came true. But I'm not sure cersei will kill brienne. She might actually survive.
Jamie already has enough ammo to want to kill his sister anyway but her being pregnant might stop that. Unless she has it by then.
Theon might kill Euron or his sister might do that if they save her whilst Euron is still alive. But I think theon will die saving her or just after. Maybe he rescues her, Euron kills theon and then she kills Euron leaving only her surviving.
I'm up in the air about John marrying dany. It all depends if bran and Sam actually tell him and if they do how they both react to it.
Harry - already merged some of my thoughts on what you said to ashes reply but although i want Jamie to kill cersei maybe arya will. She's still on her list and I think she will have crossed everyone off her list by the end (which she pretty much has with 50% of them, some of the others have been killed by other people like Joffrey & tywin and that leaves the executioner of Ned, the red woman - I doubt she will kill her, Beric - he's helped John out so she won't kill him plus he might die in battle, the mountain - she won't kill him and the hound) and She won't kill the hound either.
He could actually die whilst killing the mountain. Both together. I don't want the hound to die but I think he will. After his conversation to his bro saying you don't die that way (he means he will kill him) and to tyrion that he left that sh*t city so he didn't die in it and although he's a legend and become a partial good character he's still done enough sh*t for him to get justice to die in a harsh way and in that sh*t city. Makes sense to me
And same looking forward to those reunions (you forgot arya seeing gendry again - if that happens) and john and dany finding out the truth (if they even find out)
I can't wait for John and arya to see each other again though.
