Sans spends a large portion of the time Papyrus spends coming over just being disorientated and trying not to step all over the glass he's broken. He hadn't really intended to do that. Teleporting, maybe, even if it was a kneejerk response, but he'd come out of the shift sooner than he'd wanted. Probably because there's still nowhere for him to go.

He gives Papyrus a cornered looked as he approaches, his alarm showing plainly for a couple of moments - right before a sharp gasp goes through him, that quickly devolves into helpless, bordering on hysterical laughter.

"Just now I'm scaring you?" he manages, in total disbelief. God, what is normal for him, then? Is it really this? "Talk about a low bar for entry!"
