[Well, it makes sense that Ren wouldn't like the fake smile. Akechi doesn't like it, either, but they're still in an unknown situation, grouped with people who could turn on them at any moment under the right (or wrong) circumstances. He needs these people to like him, and if he's learned anything from just existing his entire life, it's that most people simply don't like him. (Because he's an asshole.)]

It's... possible. Tell me, there must be knives and such meant for cooking here, no? If they could be sharpened, they could become quite formidable weapons indeed. And while it might be quite barbaric, in the right hands even a heavy rock can be rather effective.

[He's still smiling pleasantly as he's talking about these weapons. Maybe he should turn that off? The smile fades into something more pensive and apropos.]
