"Kinda sucks though, right?" At least, when Tidus thinks about it... "How different are they? Yuna-" And he has to take a pause, but, "--if Yuna was a different Yuna from the one I knew, what we knew about each other wasn't that different. I was still gone, she had to go through with being a summoner, everyone suffered Sin - that sucks."

Multiple versions of the same people, going through the same suffering - or just going through another kind.
