Well, I found some similarities but I'm not too sure I'd try for connections that prove our worlds are connected or that we're alternates of someone else or another world or there's a connection otherwise. The implications of that are little absurd for my tastes. I keep my eyes peeled for them, like any sensible person placed in a centerpiece of every world would but it's not something I'd actively pursue. It's just comes off as a little pointless for me. Like it'd never get to any real resolution that'd confirm that all of these worlds are connected.

Unless you're talking about our worlds in what's similar, not with revealing what's been linked for hundreds, if not thousands, of years.
