She rolls her pant leg up. 

There is a bandage wrapped around her right calf. It doesn't particularly look like it's been changed in the week plus since the original injury was inflicted. The skin above and below the bandage is red and hot and the leg is visibly swollen. 

"I'm sorry, this is probably going to be uncomfortable but I need to have a look at that. Are you allergic to anything? It looks pretty infected and I think you'll need antibiotics but lots of people are allergic to penicillin so I'd better check." 

"I don't think so? I don't know that I would know."

She starts stripping off the bandage. 

.....Yyyyyyyyyep that sure is infected. 

"Wen Qing," Marian says levelly, "do you have a diagnostic spell that can check if someone has bacteria in their bloodstream and not just in a wound?" 

"Yes. Let me see. --Classical Chinese," she says to Anna-Sabrina.

She covers her ears and starts humming. 

She mutters in Classical Chinese and the meridians of Anna-Sabrina's body that have something that's alive and not supposed to be there light up.

"...Well, that's not great. Okay. Antibiotics. ....Fuck if I know what antibiotic is supposed to work on - I think that's probably cellulitis and I fucking hope it's not tetanus." Kid is hopefully still not listening to that part. "I should ask the void for a reference book, I guess. Does your bacteria-killing spell work internally and do you have mana to cast it?" 

"Yes. --We should get the probiotics from the void, maybe?"

"Yeah. I'll ask. And figure out what IV antibiotics we can give her, we want to get on that ASAP." To Anna, "- How have you been eating and drinking recently? Should we get you some water to drink, as well as the IV?" 

"I've been eating better than I would at home...and I've been able to find groups to get water from the bathroom with. I think I'm fine?"

....Well. That's some kind of red flag? Marian exchanges a look with Wen Qing. "I - what was your food situation at home, before this?" 

"Uh." 

She looks at the two of them and makes some quick calculations. 

"My foster parents withheld food for 'bad behavior' a lot."

The bad parents!! It's an epidemic! Wen Qing is going to write a monograph.

Marian goes very still. Takes a deep breath. 

"I - listen, so first of all I should make clear that we're going to keep anything you see here confidential. ...We can go into my bedroom or something if you want actual privacy, sorry, we don't normally have two patients at once." Another breath. "You also don't have to answer any questions you don't want to, but I'm going to ask anyway. What else did they use as punishment for 'bad' behaviour? Are - did they hit you, or hurt you otherwise...?" 

"I've been trying to tell people they hit me since my parents died and I went to live with them. But I didn't know how to find any wizards who would care, and whenever I told a mundane my foster mother would make them forget and then punish me for bad-mouthing them." 

“…I’m so sorry.”

"I'm probably going to die in here. But at least it'll be in here and not out there, with them, and whatever mal gets me will do it because it was hungry, and not because it hated me."

"There is the medicine for the bad parents, Marian-laoshi can ask the void for it."

"Does it help for foster parents too? The only thing my birth parents did wrong was dying and not specifying that I not go to my mother's cousin and her husband."

"I don't see why it wouldn't help."

"Well, magic is weird, and I don't know of any non-magical treatment for abuse besides, like, therapy, which I don't think you can pull out of the void." 

Oh man it's the facepalm-inducing explanation again. "Uh, she's - actually mostly just talking about antidepressants. Or anxiety meds. At least some of the time they do help a lot with trauma, including from abuse I think. And I actually can get therapy books from the void! I'm, uh, not trained in it though, it's not really a nursing thing. But I - I'm going to get people whatever they need, if I can." 

"Oh. I don't think I'm depressed, I never internalized the awful things they said to me. I'm pretty anxious though." 

"- That's really impressive, I think? I - good for you." Is that a horribly awkward thing to say? Marian isn't sure. "Uh, what kinds of situations tend to make you anxious, and how does that affect you?"
