Their shrinking stops as he approaches - while it's purpose is mollification, it was more for his sake than theirs here, a half-conscious reassurance. They look back towards him - they can't remember seeing a skeleton's eyes do that before, save for one notable example. It's possible S-4's did when healing Chara, but their focus had been extremely elsewhere at that time.

They nod, a small but firm movement.

"It's okay."

They see him reaching out, and they wordlessly lift Chara's arm towards him, palm down, pulling back the sleeve to expose the by-now red-magic free bruise in unspoken permission. Their permission at least. But what Chara doesn't know can't hurt them. Anymore, this evening.
