He goes quiet when Papyrus works. Quiet and completely still, seeing the rust having taken on the shape of the scar. A half-remembered explanation someone at the dig site gave him of some disease, or injury, or something that could reopen every old wound someone had gotten flickers through his mind. His wings don't so much as twitch, because any movement might make Papyrus stop. Complete stillness isn't the ideal option, he knows, but it's the safest one right now. He's only watching with his halo, which is also safer, because he can hide any little expressions he might be unintentionally making better if he's not actually facing Papyrus.]
