Uendo's words are all Sephiroth needs to slip this scenario from a simple expedition into a trap they've all willingly been lured into. It doesn't sit well with him, at all, but for now, he'll keep his peace with it. Indeed there would be time to pin this Pharce to a wall over it later; he made a mental note to touch base with Uendo about that.

Trap or not, the place has been sealed in such a way for a reason and Sephiroth is still keen to know it's secrets.

"I get the feeling it won't be the only trap we're going to need to face, here."
