You're saying his slip was him essentially bringing up possibilities of their being some behind the scenes mechanics that involve our characters, correct?

If so, that's a silly thing to assume that he slipped. The host clearly stated this was going to be a Fire Emblem mystery game and that outing who your character is might not be the best course of action.

Ergo, because the host himself has stated as such, we can probably assume there's mechanics with characters involved in which being exposed is hazardous to one's survival and town's chances of winning this.
