The thing is, with an infinity of infinite universes, where a variant can look exactly the same as their existing, prior cinematic appearances and still be a different variant of that character, there's no telling unless Rachel McAdams turns up and brands all of them with their dimensional reference (and she's created a system where there's two 616s too), so who really cares. Enjoy the meta return of an actor to a version of the character and if the MCU says it's the same one as film X (no pun intended), take it on face value?
