Do you honestly think there's anything going on with me she doesn't know?

[Deadpan. Of course she knows, but he isn't going to tell Mahiro what's wrong. He's right on his money with the thinking-- It's too much of a risk to admit to having had these spells before.]

She probably knows the contents of my underwear drawer back home, I don't think I can hide anything from her.

[He's... deadly serious about that, actually. Be very glad she hasn't nosed around you more Mahiro, be very glad.]
