Wait, I'd assume the only permanently dead ones are the ones that died before the ending (Gamorah, Vision, and maybe Loki but I'd totally expect him to come back somehow at the end of Avengers 4). I also can't see them ending that with Stark/Captain/Thor having to make a trade. It'll probably all be on the up and up the way that Avengers 2012 ended.
Isn't that the one where they hold hands and 'use the power of love' lmao?
Those Guardians films are cool but they're overrated and the second one was just obnoxious, trying too hard to be funny.
