Er...okay, 'Kenma.' [It's a bit weird, but this guy is clearly weird himself, and Yamaguchi's learned to just go along with that by now instead of questioning it (openly, at least).]

And yeah, he does! The other day, I heard him wondering out loud if 'Kenma was enjoying work, lately.' [Meeting the latter one-on-one for the first time, Yamaguchi thinks now he understands what Hinata meant by it.]
