"I always used to clean up your scrapes when you were little, remember?"

"Yes, shijie."

"And-- I just wish I could keep you safe now," she says. "I'm up late at night, worrying--"

"Shijie! You need your rest for your fibro!"

"But I can't if I'm scared that every Monday lunch I might see Wen Qing walking over to the table and telling me that you died."

"...yes, shijie."

He feels like the worst person in the entire world.

Masozi remains confused about what new information that conversation could possibly have contained for Wei Wuxian! There's no possible way he was unaware of the risk-benefit tradeoff in going to Monday morning lab? 

He will continue to be very still and quiet and wait to see if Yanli is going to talk to him too. Maybe she'll give him advice that is actually advice and has any new content. 

"You have to take these things seriously," she says. "I love you, shidi, I love the way you look at life-- I don't want to take away your courage and your optimism, it's what makes you you-- but you have to temper it with caution or you're going to die." Her voice breaks on the last word and she starts to cry.

"Oh, no, shijie, don't cry-- I'll be careful, I promise-- I'll be so careful, I'll be so good at staying alive-- please don't cry--" He hugs her.

"Promise me you'll join Jiang Cheng in Tuesday morning shop?"

"I promise."

....Is she doing a secret plan to make Wei Wuxian pay more attention to danger by crying about the danger? Masozi...will acknowledge that this does seem to work on Wei Wuxian, somehow. Maybe it's just that Wei Wuxian is very distractible and has a hard time paying attention to lectures, but crying and hugging gets his attention more? 

Masozi is going to try to offer Wei Wuxian a hug too once he's done hugging Yanli. It looks like maybe that conversation was upsetting for him and he could use one. 

Yanli, still crying, turns to Masozi. "Masozi, could I ask you for a favor please?"

"I...maybe? Can you tell me what it is?" 

"Xianxian means well, but he can be a little... reckless."

"Shijie..."

She looks at Masozi with teary sincerity. "You're so careful and cautious-- can you help take care of him, please? And tell him not to if he's about to do something that's too much of a risk?"

"...Yeah, I was already doing that? I made him wait for me to check all the cupboards." 

"But Monday morning shop is very dangerous," she says. "Only juniors and seniors should take it, and even then many of them die."

"All of the New York freshman are taking it because of Orion! I know it's not as safe for us because New York is mad at Shanghai, but he'll still get most of the mals, he likes killing them so much." 

"If New York assassinates you," Jiang Yanli says, "they're not going to do it by deliberately killing you. They're going to do it by having Orion not kill a mal and then, oh no, what could Shanghai have expected, we knew that shop was dangerous, there's nothing that could be done--" She starts to cry again. "And then you'll be dead and maybe a-Xian will be dead and there's nothing any of us can do about it."

Translating this is making Wei Wuxian feel like he kicked a puppy.

....Oh no he hadn't considered that - or he had but he hadn't thought it all the way through, he'd just figured that Wei Wuxian was good at fighting - but of course Wei Wuxian would try to save Masozi, if he were under attack, and - he wouldn't think to be careful, and if Masozi were hurt then he might not be able to remind him, and....actually it seems possible that Wei Wuxian wouldn't even listen if Masozi told him to RUN AWAY instead of trying to save his life... 

"...That makes sense. I - maybe we can just go next week again, if the mals still aren't very bad - or we could go with a lot of people right after curfew and clear it out...?" He really wants Monday morning shop! He got so much stuff! 

"I'm very worried that Xianxian won't be careful enough even with you there."

That's fair enough but ouch.
