0% chance the evaporated are permadead.
1. Black Panther is a new franchise for them and had the largest domestic take EVER for a comic book movie. Not dead.
2. Spidey is not theirs to kill. Sony owns Spidey and has invested a lot in the new Spider-Man revamps.
As a Game of Thrones fans it reminds me of when Jon Snow died at the end of season 5. You knew plot armor wise they had to bring him back.
Only Permadead is Yondar, Loki and probably Gamorra (her death was tied to Soul stone so possible not).
add me, the more the merrier.
