The irony here is that this version of Kiritsugu never met Irisviel to begin with, and thus wouldn't recognize Illya at all.
perhaps, but the events showed that him and Irisviel couldn't be kept apart so easily. I suspect he'd somehow treat Illya the same way.
It's for myself after all!I want to go too!Well then, let's go look for some walnuts.Is there anyone who can go with...It's dangerous!
Ah, but maybe I can bring you to raise bond.You need walnuts for Ascension, Illya?I don't have enough right now...
I'll go look for some, so wait a bit, okay?
