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.
But the floor is a perfectly fine place to be flopped fine, he will accept Wen Qing's help to drag himself back onto the bed, and then burrow under his blanket and wish he had a second blanket or, better yet, snuggles from Lan Xichen. At which point he has to remind himself that almost certainly Lan Xichen is not going to want to snuggle him when he's sick, he probably smells terrible again.
Wei Wuxian is also a fairly comforting person to have there, even if he's not Lan Xichen.
Masozi tries to sit up without unblanketing any part of himself below the chin. "Why, is something else happening?"
"Boston is full of idiots and that's all I have to say about it. Drink, I went through hell for this."
Whatever, probably it's not an emergency that Masozi needs to worry about right now, then? He accepts the water and sips it carefully; his stomach gurgles uneasily about this but he's not exactly nauseated and the sip of water stays down.
He tries to find a more comfortable half-propped-up position where he doesn't have to support himself, but this is hard to figure out when he only has one somewhat sad and deflated pillow.
"Excellent. Go get Masozi some the pillows. --Masozi, you have to drink this entire potion. I'm so sorry, it tastes disgusting, but if you were poisoned it will keep you alive."
"Okay."
He will try to drink all of the disgusting potion! It's incredibly disgusting! Despite the anti-nausea spell, it keeps making him gag, and he's uncomfortably aware that his stomach has contents again, and does not exactly approve of this right now.
Eventually he's drunk all of the horrible potion! Unfortunately he gets to continue to taste the horribleness every time he burps!
....Does he, in addition to drinking it, also have to not throw it up again. Is there a minimum time limit he has to manage to keep it down or something.
"Do you think you can keep it down or should I go for the heavier-duty anti-nausea spell?"
"Maybe? I - I don't know -" He tries to reach the water jug again, maybe getting some of the horrible taste out of his mouth will help. "S'just - a lot of potion."
"It's up to you-- the other anti-nausea spell will last longer and you definitely won't throw up the potion, which is good because the longer it's in your system the more time it has to soak up the potion, but it tends to make people... loopy."
Masozi considers this. "...You're helping guard me from mals, right. So s'probably okay if I'm out of it? I - I would like to feel less bad. Hard to think anyway."
"I can also give you a pain relief spell for the aches-- the pain is still there but it makes you care less. --Actually, if he's coming to sit with you, Lan Xichen should do it, it's in-affinity for him."
Masozi probably doesn't need the bucket if Wen Qing is going to cast the stronger spell, but it's reassuring to have nearby just because the horrible potion will make such a disgusting mess if he does throw up again.
He will try to get as comfortable as he can with Wei Wuxian's delivery of additional pillows, and wait for Lan Xichen to arrive.
....Wow. That's really weird. On the one hand, he feels...almost fine? Certainly a lot closer to actually comfortable. On the other hand, everything is suddenly...sort of pink? And objects have gauzy halos around them. And his hands feel weirdly like balloons, which might float away in the breeze, not that the Scholomance has breezes. Also it takes him three tries to get the water jug to his mouth, because his vision seems to be weirdly offset by about an inch.
He can swallow a normal sized sip of water without it feeling unpleasant, though! Which reminds him that he's still very thirsty and it's tempting to gulp the rest, but he probably shouldn't push it too far.
"Yes. Watch him, make sure he doesn't get worse, get him refills of water. He's on the heavy-duty anti-nausea spell now. Do your homework."
"Good. It would be embarrassing if we lost our leader because you got eaten by History of South India."
