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.
"Oh, no, how was a-Ying the one that remembered that we needed to do something? Are you possessed by a ghost? Are you a mimic in human shape?"
Nie Huaisang doesn't dignify this with an answer. "Wei Ying, Lan Wangji, come with me."
There is, eventually, some sort of answering mumble but not one that's comprehensible through the closed door. Which remains closed.
(It's not barricaded with the desk, though; Masozi was not at all in the mood to move furniture around earlier. It's actually not even locked.)
This is kind humiliating, actually, or at least it would be if Masozi were tracking the outside world much at all instead of curling up in a ball and holding as still as he can and vying by sheer force of will not to throw up again. He feels terrible and it keeps on going and to make matters worse, at one point he didn't react in time to reach the void wall and managed to puke on his bed. Which is why he's now lying backwards and diagonally on it. And also mostly naked, again, because Sophie's beautiful clothes did not deserve this, and he managed to stash them safely in the corner.
He would try to see who's just come into his room but that would require moving, which, nope.
"Wei Ying can you deal with this-- I have a sensitive stomach, it'll just make the problem worse--"
Does he have to answer questions by talking now. This is incredibly unfair.
"...Not really. Stomach - really hurts." And so does most of his body, at this point, and he's gross and clammy with sweat all over, and his head is pounding and he's agonizingly thirsty. Specifying that would take too many words though.
"Okay. Wen Qing's going to be here soon, I need you to answer some questions for me, okay?"
He starts checking Masozi's body for injury.
His pulse is very fast, but fairly strong and easy to feel.
Masozi feels like it is quite self-evident what’s bothering him but apparently it’s important that he answer stupid questions using words even though this sucks.
“Feel sick.”
"You gotta tell me what kind of sick, Zaizai, or we won't be able to make you feel better."
Okay, he's supposed to look at skin color... Masozi looks basically normal? He has no idea what kinds of skin colors are concerning for black people.
“Lunch?” Masozi says uncertainly. Please please please do not ask him to provide an itemized list, he doesn’t remember and also doesn’t want to think about anything in that entire genre.
His skin feels maybe a bit warmer than it should, but mostly he’s just soaked in sweat.
