Why is this happening. Why is this a problem that is happening.
She's not going to go healing people's burns and cuts and bruises when they don't want her to. But she did hear 'concussion'.
"Anything else here that needs to be done right now, then?" she asks, partially because she does want an answer, and partially to cover for the fact that she's extending magic (it's not exactly ideal to not be able to get all the way closer, but she walked pretty close, and also she's herself and she can do it.)
Do any other the others have any sort of injury or risk with respect to the 'brain' part of them? Does this one have anything actually more serious? If not she can focus on the concussion thing. Magic, magic, various manipulations - concussions can cause long term problems and now that is not going to be happening. Still won't be happening even if the subject disobeys a bunch of guidelines on what to do next (if they have those here).
(Her subject won't feel anything.)
(This is not, technically, healing - she's setting things up to avoid future problems, not fixing current ones - but she's not actually unclear on what she's doing or under any impression that this makes it somehow not count as going against their stated wishes.
She's also going to do it anyway.)
