He can't help a pang of guilt when he sees just how shaken Papyrus looks. "We need to lick our wounds and get out of here. There's a good chance that there's a lot of these guys, and they might be hurting people. We still don't know where the others are."
He reaches out to put a hand on Papyrus' shoulder.
