Given how many realities I seem to exist in, as well as those from my world, I wouldn't rule out the possibility of there being at least one other reality similar to your world but with marked differences. But it also seems like, from my incredibly limited experience and perspective, that maybe some changes would always (or almost always) happen. Maybe 99 out of 100 realities you will always end up in Lakewood somehow.
I think knowing you exist in different realities is more stress than it's worth. Maybe it'd be cool to meet another version of yourself, but what if you're a dick in another reality? Then people here expect you to be a dick, and you're not. Like how Klara and Molly except Tony and Steve to be jerks, but they're really not. I mean, okay, Cap dropped an airplane gangway on me, but I know it wasn't a dick move. But it's also nice to know there's variety out there, that it isn't all some slight to drastic variation on the same reality. Yeah, there's enough variables it would result in some drastically different ones, but it'd also be kind of boring, you know?
