I don't know how any of this will happen, I haven't read the books, and I'm usually hazy on the details of the past week's episode :joint:
Jon will die, but not before winning the war, though Cersei will die by Sansa's hand, in the end. Dany will not die. Grey Worm will **** Captain Abominable (see?...details?), the Shrek-golem that ****ed his girl. And the outcome will be... wait for it... not unlike AOC's suggestion at season's start, a (sort of, anyway) co-regency (democracy was the word she used, but that's a bridge too far, imo). Throne and council, or what, I don't know. That's where the vision is harder to see. Thus it is written. By Dick.
Also, Jaime's on borrowed time, the next to go. So sayeth Dick.
