Greta watches him sidelong, curious to see if there will be any visible change (she assumes her observations wouldn't make any difference regarding whether it works or not). Perhaps the bandages will drop right off, or disappear entirely.

She's definitely not braced for a cry of pain, and she startles almost to the point of toppling right off the rock. "Are you all right?" she asks, laying a hand on his back, the gesture serving both to comfort him and steady herself. "Did…" she trails off as he moves his arm freely. It must have worked. She releases a breath, then takes back her hand so she can start undoing the bandages. He won't need them anymore if he's fully healed, and she rather wants to check for herself.

"That was certainly dramatic," she mutters, faintly scolding, though there's a smile tugging at her lips.
