Strange coincidence, that—though he knows Quite Enough of Tohru Adachi by now, and the comparison hasn't escaped him.

But actually, he does have a question. "I get that a lot. I'm afraid it's just the way I'm wired. You're—Kanji Tatsumi, then, is that right?" Near-victim of the Inaba killer, yes. His younger self's "Emperor Arcana", which sounds... well, arcane, but is significant. Someone who showed "unconditional love and support" to an orphan boy in need.

If it's not Kanji, he'll laugh, and say he was mistaken. It's a trick he uses quite often—though if this is Tatsumi, Akechi didn't expect him to be quite so like Sakamoto.
