A girl who's pale even for a white person approaches him cautiously. 

"You're Shanghai, right?"

An exhausted-looking slightly-tan kid trudges through the door, sporting a purplish jaw bruise. 

"Yeah! But I'm fluent in English."

She sits down next to him; he seems friendly enough. "Cool. I'm fluent in Mandarin. How do you feel about spiders?"

Masozi walks in, and first checks the room for mals, before he bothers processing all his visual data to recognize people. 

- oh, that's Wei Wuxian! 

He waves, and heads over. "Hi! ...I should maybe not sit too close to you, I want to keep lookout for other people here too." 

"Sounds good!"

Lucy waves lightly to Masozi.

How nice that anyone else wants to keep a lookout. Good to know someone else might catch anything he misses, maybe, if he's lucky.

He isn't sure if it's rude here to ask about other people's bruises, and they have class anyway, so he doesn't say anything about it, but he looks a little longer at Alexius than he does at anyone else.

"I love spiders!" Wei Wuxian says. "I have cockroaches myself."

"Cool!" She holds up a hand for Atlach to skitter demonstratively over. "What do your roaches do? My twin brother and I have spiders because his affinity is thread."

"My brother's affinity is animals and mine is dead things, so we've kind of got them covered coming and going."

Okay, so one of the drama-laden Shanghai people and the creepy boy who seems to have fallen in with them (admittedly looking a lot less creepy now that he's had a day in an environment created by people from the first world), and some people she's never seen before, and the spidersilk person. She'll go sit next to the spidersilk person; proximity to Shanghai and creepy boy isn't that much of a cost because she wants to know what's up with them anyway and "in class with tons of witnesses" is as good a place to do that as any.

"Hi," she says, sliding into a seat. "What do you do with dead roaches?"

"Well, not much so far, I'm a freshman."

"We're freshmen, and Wilbur made all our clothes. Admittedly spiders are probably easier to use for silk than roaches are for...sorry, I haven't spent two years cultivating an interest in roaches, I know less about them."

"Fair point; what are you hoping to be able to do with dead roaches?"

"Get them to move again and then I can be followed around wherever I go by hundreds of zombie cockroaches."

...Lucy is not going to criticize that plan because he is from Shanghai and she is an indie. 

She will, however, take advantage of it. "Do you want to add zombie spiders to the mix? My brother's and my familiars are a breeding pair."

"I guess if you can get them to be lookouts and mal-bait that's pretty helpful." Not everyone can have an awesome affinity.

"Oh, man, that would be badass. Absolutely. Next time you have a dead spider send 'em my way."

"Okay! --Can you do anything with dead mals, because that has the potential to be really badass."

"Oh hey, Lucy, you should talk to my enclavemate Franklin, his affinity is containers and he's trying to convince it that armor is a type of container, I bet he'd be into the silk. Also wow, yeah, dead mals would be awesome if you don't accidentally terrify everyone."

"I haven't tried with dead mals. I should."

"If I kill a mal and it's in any shape to carry I'll sell it to you."

"I would love to talk to your enclavemate!" She would pretty much love to talk to anyone from any enclave at any time, enclavers liking her silk is very good for her survival prospects. "Armor should totally be a type of container, but that's an argument Wilbur is a lot more likely to win than I am."

"How come; is he good at arguing with affinities?" Is that even a thing you can be good at?
