[Something about Heizou seems to relax, just a little, at this line of questioning. It's faint enough to be missed, but he doesn't try to hide it and nor does he try to hide the faint smile that quirks at one corner of his mouth.]

I've met him. We got into a scrap together when we got here, he had my back. [Eh, not Heizou's ideal way of meeting someone, but beggars can't be choosers.] Paid him back with lunch on me. He hated that, at least until I told him I'm older than he is.

[The detective laughs then, leaning back in the grass and resting his weight against the heels of his hands.]

Haven't been mistaken for a teenager in a while. That gave me a good chuckle.
