Do we ever know for sure? It's clear he considers Conan to be super smart in the manga, but is he just accepting that Conan's a smart kid...or does he know about Shinichi?
I'm watching movie 8 right now, and it seems like he knows b/c of the smirk on his face when Conan's screaming that he's not Shinichi. And in movie 3, he comes back as Shinichi to save Conan from revealing the truth. But since the movies aren't considered canon...
Just curious! What do ya'll think?
