He doesn't mean it as the situation had been acceptable - just that this little Vash need not be sorry about it or the pain it caused him. That pain was dull now, it was okay to keep feeling it as it was.

A little harder to accept, the idea of letting go of a warm, friendly touch. But he does. "You disappear a lot?"

Just because it didn't happen to him doesn't mean it didn't happen to other people. "Maybe you're a little right. I don't think it's .. about me or just my friends." There's too many of the parts of him around. Who's to say this was the one he destroyed? "Not if the whole city appears.. and then there's the other one I don't even recognize. Maybe ... it's about them. Two whole cities of people, and our kin keep trying to put them here and save everyone." He's not sure either, that's obvious, he's working through it in pretty much the same fashion. "But putting two entire populated cities on one spot isn't really going to work."
