If two parallel worlds would combine, what would change?
It's as the realms were Venn diagrams. Conjoined. They're seperate.
If you were in a situation like Karada, a teenage girl with typical teenage angst, you'd be ecstatic to find a true friend and sister. A real twin. Out of everything in the universes of all the worlds, you have a single new friend to spend all the time with. All the happiness you've never gotten suddenly fills you.
As if you finally found your other half.
