Shirou: Hey gramps, the medicine you gave me this morning.... Can I take some now?

Kiritsugu: Hm? It's still rather too soon for that but.... Fine, I guess. But what's the occasion here? You always hated that medicine, didn't you?

Shirou: Of course I don't like it. It's bitter and it's mushy and all... But gramps, you made that medicine with magic didn't you?

Kiritsugu: Well, it's magecraft to be specific. But yeah, somewhere along that line.

Shirou: When I think of it that way, it sorts of calms me down. I get uneasy in this kind of night...

Kiritsugu: I see.... Can't really blame you for that...
