Giggle.

Wei Wuxian hunts down someone who sells masks and buys a better one for Wen Ning. Wen Ning's ongoing state of masked-ness is explained to Jingyi and Sizhui (A-Yuan!!! A-Yuan who is alive!!!) as his being from an obscure temple sect that forbids showing one's face; if either of them is skeptical, they don't let it show. 

Wei Wuxian continues periodically pestering Isabella with questions about her magic and her world in general. (He seems oddly fascinated with with role-related social norms.) 

(Lan Wangji has never been so glad in his life that although his ears are bright pink his face itself shows no sign of flushing.)

Isabella will tell "Mo Xuanyu" whatever he would like to know about subs being led about on leashes and doms swatting them for backtalk each according to their personal relationship tastes and situation.

Cool. 

"Ooh, hey, do any of your fancy otherworldly imports have anything to do with alcohol?" 

"Uh, only the kind you can't drink that's useful for cleaning."

"Aww. Oh well. You really do fit in with the Lans, don't you." 

"I was briefly concerned that it would be a requirement that I convert to Buddhism but it transpired that it was not."

"What?" 

"The five poisons and suchlike."

"Hm. You might have to explain." He smirks covertly at Lan Zhan. "I don't know much about the Lan sect rules." 

(This is a blatant lie. Even without eidetic memory, he could recite every single one that was already there when he studied there, with how many times he was forced to copy them.) 

"I have better things to do. If you forget one you can read it."

"That's really reasonable actually. What about you, Lan Zhan, do you have better things to do?" 

Oh no how did this happen. 

Hm. 

"If Mo Xuanyu wishes for the Lan sect rules and the principles behind them to be explained, this can be arranged." 

"You know what, never mind," he says, shuddering theatrically and bringing his hands up to cover his ears. 

(Success) 

"Does your world even have Buddhism and Daoism, if it doesn't have cultivation?"

"Yeah! It has a bizarre number of similarities despite the magic differences and the role thing. Like, by the time I could talk to anyone besides my little brother Alex" (switching accents for this mid-sentence is awkward but there's not a great way to translate the sounds in fewer than four syllables plus a lot of fudging, so she does it anyway) "I could speak the local language, and it's about like the equivalent language at the equivalent time on my planet."

"Really? Even around gender and role and stuff?"

"Lots of historical cultures on our planet erroneously conflated gender and role. There's a few differences but not as many as you might think. Besides, most of the gender in this language is about people's relatives, and gender matters more in that context where you want to know how people are related. Relatedly, I am still annoyed that I have to call Alex my 'little brother' because you don't have an age-neutral word! He is minutes younger than me!"

"Haha, sorry." 

"Is it your fault? Fix it immediately." She snaps her fingers.

Huh being jealous of Isabella sure is a new and unpleasant experience. 

"I would if I could!"
