Recognition comes quietly, without much fuss. He knows that face and remembers that voice, even if he never expected to see or hear either of them again. Archer detaches himself casually from any foolish thoughts where it matters who this man is. The only thing that should be of import is that Kiritsugu is from the same world as him. That's all.

His face betrays no conflict. "It's been at least four years. That's if you believe them...but I see no reason not to. It's too elaborate a backdrop to be purely illusion." He shows no hint that it bothers him at all that his own identity wasn't asked after. Why should it, anyway? "If it makes you feel better--it seems time doesn't pass in our world while we're here. I can verify this."

But for all his calm, he's still not looking Kiritsugu in the eye.
