"yeah. exactly." He smiles faintly, glad they're on the same page. Apologizing is hard and awkward enough without them talking past each other or something.

"it's the same in reverse, too. pile on too much emotion and you're not really you, either. if you can't think straight or reason you're just kinda...i dunno. an animal."

He frowns a little when Frisk pulls out the knife. For a moment he can't even tell that it's the same knife. But it must be. The exact same shape and size, just without the...red.

"that's good. i'm glad they're being reasonable." He tilts his head at the knife. "i didn't know it could just turn into a normal knife."
