-Dany and Jon both die. He kills her, then dies from wounds he suffered while fighting Grey Worm (who will obviously die)
-Westeros goes full Yugoslavia, becomes eight independent kingdoms (not sure what happens to the Crownlands, but it's mostly scorched at this point, so just split it between the Riverlands and the Stormlands I guess.)
-Drogon gets killed in the most implausible way for a dragon yet. I don't know how, maybe Arya stabs it or something
-Titty Boi Aryn comes back wearing not just one of those chains that highborn people wear over their tunics, but rather two of those chainz, and now everyone likes him
-Tyrion somehow doesn't get killed
-Bronn is the only person who gets a genuinely happy ending. Close second to Brienne, who will get a satisfying, but probably kinda bittersweet ending
