Masozi is, presumably, spending the afternoon safely ensconced in his room and studying Mandarin. The first hint of something wrong is when he fails to appear at the Shanghai table for dinner, even well after all the other freshman have made it over.
She says a rapid poem in Arabic, thinking that Masozi is in no way paying enough attention to accidentally pick up Arabic.
The spell doesn't completely knock out the nausea, and it doesn't do anything about the part where his entire gut is tied into agonizing knots of cramps, or where all his joints and muscles feel achy and his throat really hurts and his head is pounding dully. But it's a significant improvement.
He experiments with turning his head, notes that this seems allowed, and tries half-rolling toward Wen Qing so he can see what's going on. This does not result in throwing up, like it did the last three or four times he tried to shift position.
"Am I maybe going to die?" he asks Wen Qing, plaintively.
He will do his best to describe everything for her. "At first I just felt - kind of bad but not specific? And I was tired and wanted to lie down and it was hard to study. And then I started getting awful cramps in my belly, and I tried drinking more water to see if it'd help but it really didn't. And - then I think my whole body hurting was just getting worse and worse, at the start it was just my stomach." He shivers. "- What time is it now?"
"Dinnertime. --So it could be induction flu or it could be poisoning. Have you eaten anything from the vending machine in the past two days?"
"...Yeah. Had - something at lunch? 'Cause I'm - supposed to be eating more..."
Masozi feels like the current outcome is KIND OF THE OPPOSITE OF THE GOAL THERE.
Another quick burst of Arabic. "It's the stomach poisoning but the spell doesn't say if it's the food poisoning or the malicious poisoning. --Nie Huaisang, my room, charcoal."
Masozi didn't particularly follow that exchange. He's thinking that he's cold and feels terrible and wishes that Lan Xichen could hug him and this would result in less feeling terrible. It probably wouldn't, though, and also he's not exactly in a huggable state right now.
"...Can I have water?" he eventually thinks to ask. "I'm thirsty."
"Wei Wuxian. Water. --Do you have any idea of anything you might have swallowed during shop?"
Masozi's enthusiasm for trying to stand up is well below zero, but he's willing to make the attempt. Well. Starting with just sitting up, at which point he's very lightheaded, and puts his head down on his knees again. "- Don't know if I can. I can - lie on the floor?"
"I'm hoping to keep him on the anti-nausea spell but it'll be good for after dinner."
He leaves to take the sheets to the minion who does laundry and to find a bucket of some kind.
"So we don't know what you took, if it's poisoning, which makes the treatment harder. I'm going to give you the charcoal, it tastes awful but it's a good broad-spectrum anti-poison potion. If it's food poisoning it should clear up on its own in a day or so. Drink plenty of the water."
"Mmmkay." He is now very stuck on the floor and is maybe just going to stay there until Wen Qing volunteers to put in the effort required to change this situation. "Where's Lan Xichen?" he adds, tentatively, after a moment. "Can he - I want..." Actually make this is an unreasonable thing to ask for and he shouldn't? He trails off.
"You're going to need someone to watch you to see if you get worse and make sure you have water, I don't see any reason why Lan Xichen can't be that person."
"You'll be alone overnight but someone-- Lan Xichen, if you like-- will come sit with you the first thing in the morning."
"Okay." It's the first week of school; he probably won't be eaten by a mal in the middle of the night, and if Lan Xichen is worried about it he can figure out extra wards.
He closes his eyes and drifts, still too generally uncomfortable to actually manage sleep, but a lot less miserable than before.
