It's a gift, and a curse. Nonetheless, Papyrus nods along to Sans' explanation, understanding enough to get that Lambert's idea of the whole situation had been more accurate than his own... and one inescapable detail.

"So, I was walking around in your dust... That's pretty disturbing." Walking in anybody's dust was bad enough, but it was to get Sans. And, he'd figured, if the giant wolf could come back from the dead once, it could surely do so again.

"Does that happen every time you shapeshift? I don't know if I can handle... sweeping all that up. Or just disposing of the dust like it's any other mess. But how do you have a funeral, if the person's still alive? What a conundrum."

Papyrus loses track of watching Sans' expression, too busy talking to himself about these important questions.
