She's a witch. Like, a...good witch. I broke my arm in Canada only no one ever knew because she healed it. She didn't really want to tell anyone because you know, being a witch and a witch hunter - kind of contradictory. But after the last room she felt bad just sitting by when there are injured people.
So she said if you or your crew needs help, she'd do that. If you wanted. Because she trusts you all to not make a big deal out of it.
