Grey Worm, Lady Brienne, Pod, Tormund, Ser Jorah, Davos, Gendry, and Theon I think are all basically 100 percent dead next episode.
I think the Hound still has Clegane Bowl to look forward too.
Wouldn’t surprise me if one of the major major characters dies as well, with Arya and Tyrion the most likely. Arya is 100 percent gonna try to murc the Night King or Ice Dragon with her new dragon glass spear and I could see it not working out super well for her.
Also who knows if the Night King is even there or if he is flying south to fuck up somewhere else.
