[Crow is pretty sure he did see that written or spoken somewhere during the announcement, but even if that wasn't the case and he's mistaken somehow, there's no telling whether or not it would help or change anything.

Instead of giving a verbal reply, he looks upward, as if listening for something, and then...starts removing pieces of clothing--his scarf to start with, and then (after a slight moment of hesitation) starts shrugging off that purple technicolor jacket he's always wearing. Once he does so, you'll now be able to see his bare arms. Much like that one glimpse of his wrist you got a long time ago before, Firo will now see more metal, being held together by screws and the like at the joints. The same goes for what appears to be the rest of his body, since the metal extends upward to his shoulders and his chest.

Normally, he would be hesitant to allow anyone other than Seto see that much of what he looks like without the jacket, but he's a man on a mission, so to speak, as he starts pushing aside the purple suspenders he wears underneath the jacket so that he can get to a spot somewhere on his back.]

...On my back there's this thing that opens and has some stuff in there. Look at it and tell me if you've ever seen anything that looks like what's in there back where you're from.

[Sure enough, there is a panel being held closed with some screws, but after fishing through one of his pockets he finds a screwdriver to hand over; however, he's quick to add--]

But don't touch anything, just look and then close it back up again for me.

[Can you guess why he's doing this now, Firo.]
