Yeah, I'm not planning on spoiling why Mateus is interested in Terra, but I will say it's sort of personal. Mateus wouldn't really need to give any indication to Kefka that he knows Firion -- he can simply emphasize the fact that the trio in the Mist Cave is seemingly more experienced and prepared than the other groups (who are either young and in disarray, or are outnumbered), so it's logical to make sure the bulk of the evil forces are directed there to eliminate them quickly. He'll likely send more than one Hell Knight after Firion unless Kefka offers something significant.

At any rate, it makes sense that we should get Gohan's input first.
