Raine's fairly versatile when it comes to medicinal/doctoring/healing, so if they set up a system between them they should be good. The flood situation will freak her out a bit but she's fairly good at prioritizing her work and duties when it really comes down to it. CR in the know might pick up on any unsettledness.

She would be wary of people using too much of the filial magic in case it brings Shift hunters down on them, but it also depends on the severity of some of the injuries; they might not have a choice in some cases.
