[Such familiarity is there for Zero all the same, as well, even while it's also the first time he's actually met Ren. Maybe that just makes sense, though. It doesn't need to be complicated.]
It is. Very much so.
[First Ai, now Ren. Whatever trials there may be at home - and Zero doesn't even need to guess that there will be plenty. Even the basic fact that a vampire is set to lead the Hunters' Association (or, hell, even just being a hunter in general) is something that will attract a great deal of resentment. But regardless to all of it, there's so much good that comes out of the future ahead of him (and Yuuki), as well.
A real family. Something which he hasn't especially felt in a while, now.]
I don't have to wait for then. [It's too long.] Will you tell me about yourself?
