Every single character that had their big moment of redemption or catharsis in this episode is going to die. None are major plot drivers but all supplementary. So Jorah, Brienne, Theon, Grey Worm are all going to die. Possibly Gendry. What else is there really left for them to do now?
Other interesting things:
- let us never speak of the Arya sex scene again but perhaps the seed is strong and she's got a Baby Baratheon now
- no Night King at all, might be flying down south to KL
- if he's around, he's going to certainly bring the dead back to life in the crypt. Headless zombie Ned
- Ghost is back, I bet Nymeria pops up somewhere next
- assuming the Northern living win or at least don't die out completely, how can they kill the Night King? It's likely only going to be Valyrian Steel that can kill him. That leaves a handful of people with a Valyrian Steel weapon. Maybe Arya with the dagger? Though I would guess her last big contribution will be to don Jamie's face and get her revenge on Cersei.
