Loki was having it set up that infinity stones only work in their home universe which is consistent with the comics.
Also not really clear how he was able to just split 4 infinity stone Thanos in half with just the mind stone. Does that mean Vision could have just obliterated Thanos at any time?
Assuming they are making a version of the Exiles, I believe they were taken from their universes moments before they would have died in an accident or bad event, so their timelines and universes were unaffected, however, I don't know how that works with the characters we've been introduced to so far, other than Strange.Although I do wonder how it will end - half these people come from fucked universes. Do they have to go back, or do they get to move to a different universe? Or do they just kill them all off to avoid that question lol
