[Peter] I mean, generally speaking, this visit should be the majority of people's first visits, but some people have been here a long time and others are from worlds where the concept of the multiverse and traveling around it is more common. I was on a universe hopping adventure right before I got pulled here so it wasn't even a bump in the road for me.
Ok, so, uh, the warning on the multiverse tin? That'd be helpful, right? Especially with Tweedle Dee and Tweedle Dum down there. Anyways, first off, people can come and go from this world we're in now. Sometimes they keep the memories, sometimes the memories of when they're here don't stick. A version of you has been here before, so some people may know you that you don't know. It can be a headache, but you'll get used to it. Just, y'know, so you don't freak out at people just knowing you.
And more with the multiverse, infinite numbers of possibilities and all, right? Well, your universe is a bit popular for having multiple versions, so some people might know a different version of you either from their world or one that's visited here before. There's actually another Peter Parker here. Bit older. So also, don't freak out?
That's a lot of information. That was too much information wasn't it...
