I can't imagine this hypothetical scenario
*Season 5 spoiler alert*
If >!Fitz didn't die and the team managed to save the Earth and everything!< ,would we have >!2 versions of Fitz living in the same universe?!< Like daamn, how would that even work
I'd also like to say that I don't understand how could >!Jemma be with the other version of Fitz.!< Ik some people are gonna tell me that time travel works that way, that it's a different universe only if you change something but that makes no sense to me. As far as I know, in marvel (so in Avengers too) time travel is showed as something that doesn't exist and the only thing similar to it is traveling to another universe. So when they first came to see >!the Earth broken in pieces!< etc it was already another universe if you ask me. So Jemma should've known that >!The Fitz that traveled 70 years to them is actually not their Fitz but another one.!<
