I wouldn't think a 'great detective' would get so wound up about someone else's theory being proven wrong, and come all this way just to rub it in his face.

[For once in his life, he's not rising to the bait - mostly because he's willing to admit whenever he's wrong. That, and Erika wants a reaction out of him, and he's not going to give her the pleasure of it.]

Or that she'd let someone else solve the murder ahead of her.

[HE'S TALKING ABOUT AKIRA DOING DETECTIVE WORK.]

But hey, if it makes you feel better about being upstaged by insulting me, be my guest, 'great detective.'
