"Here's your tea, zhuren."

"Gross. The weird foreign medicine tastes way better."

He must be very electrolyte-deficient if the stuff tastes good to him, Merrin thinks. "I'm sorry. Just try to sip some of it and then you can go back to the tastier one." 

He can have tea and congee and lots of encouragement and Merrin will desperately hope that this does not result in her being vomited on. She only has the one pair of clothes. 

He does in fact throw up on her clothes and then says, "that wouldn't have happened if you hadn't made me drink gross medicine."

"I really don't think that's why, but noted," Merrin says dryly, hiding any visible signs of annoyance or discomfort about the clothes. She can deal with it later. At least he drank nearly all of the sugar-salt-water, and hopefully enough of it stayed in his system. "I think no more solid food right now and you should lie down for a bit. We'll need to wash the top blanket but I think the others are all right." 

She eases him down onto the floor of the tent. Gets him arranged on his side, in case he vomits again and isn't alert enough to keep his airway clear, and tucks him in with the unsoiled blankets. She spares thirty seconds for being grumpy about the fact that she can't give him iron supplements. Actually he's probably deficient in every vitamin and mineral that exists. It's a reasonable assumption to make and she's going to have to keep operating based on priors because she can't run any tests, due to being trapped in Low Tech Fantasy World. 

She scoots over to where Wen Ning is and lowers her voice. "Can you sit with him and, um, maybe you can sing to him and stuff again? It might help him fall asleep. He's very distractible." 

Speaking of distraction--

"Get Mistress Dath some real clothes. Lan robes, probably. And commission her some robes in my colors."

"Zhuren, the Lan are gender segregated and we have a male battalion at the camp. The Jin are here?"

"Why do they even bother."

"Sexual purity?"

"The virtuous Lan boys could fuck a Jin girl. Or a whore. Or each other."

"Try to get some sleep," Merrin says, tiredly. "My clothes are not an emergency. What are Lan robes anyway? And, um, I - have questions about the 'gender segregated' part but I'm...not sure I have specific questions yet so much as, just, what. In general. But that question is also not an emergency." 

It turns out to be almost impossible to think while Wei Wuxian is awake and talking, and Merrin is pretty sure she has a significant backlog of thoughts that she made previous mental notes about and needs to finish having. 

"I will sleep when you have robes that don't have vomit on them!"

"I don't want her to look like a peacock. Get her the male Lan robes, they look the same."

"Zhuren, I have a sleeping draught for you, if the doctor says it's all right?"

"I don't need a sleeping draught. I feel fine. Well-rested."

"You may feel that way but you aren't. My medical opinion is that you would benefit a lot from resting more. Wen Ning says you haven't been getting a lot of sleep. If you have spare, um, robes, that's very generous and I would be grateful." And she can figure out what...political signalling?? they involve later, by asking Wen Ning, who gives much clearer answers to questions.

She turns back to Wen Ning. "...Um, what are the side effects of that? Without being familiar with it I can't say for sure that it's safe - um, if he's taken it before and been fine then it's probably okay now? He may be more sensitive to sedating effects because he's so undernourished, but you could presumably just give him less." 

"It allows the body to rest so the qi can rebuild."

"I have plenty of qi."

Wen Ning puts the sleeping draught in front of him.

He drinks it. Under protest.

"Thank you," Merrin says fervently to Wen Ning. "Wei Wuxian, are you warm enough?" She checks whether he still feels clammy. 

"I could use Wen Ning?" Wei Wuxian says hopefully.

"Zhuren, would you prefer I get Mistress Dath robes or warm your bed?"

"Ugh, fine, get me another blanket."

He closes his eyes.

"How long will it take to get robes? Um, if there's sewing involved I know how to sew." Her experience of sewing with fabric, rather than suturing injuries, is very limited, but she does, technically, know how. "I do think it's also important for him to be warm enough, he can't afford to be burning extra energy on staying warm."
