Okay for FUCK'S SAKE - 

Marian briefly considers whether to delegate "answering the door" and decides that, actually, in this specific instance, everyone else seems to be even more occupied than she is? ....She's not really doing anything useful, right now. Wen Qing is doing vital signs and also knows mysterious medical magic, and the New York kids are - panicking about mysterious New York criminal investigation stuff??? And she's not, in fact, doing anything incredibly urgent right this second. 

She answers the door. "Uh, hey. Is this an emergency." 

"-no. I'll drop by later this week?"

"Okaysurethatsoundsgreat–" 

Pause. 

"....Uh, what do you - want to ask me about later...?" She should at least update her notebook, so she can maybe, possibly, research it in advance and have any idea what she's talking about.

"Antivenins, antidotes. Substances that work against poisons."

- okay, fuck. 

"I - wait, sorry - are there mals that are poisonous? I mean, like, the kind of poisonous that there are antivenins for?" 

"It's not urgent. I have an affinity that would be very convenient if I had a head for alchemy. I don't, so I'm looking into mundane options to supplement it. Since you're busy, I'll come back later."

"....Okay. Uh, Sure. What was your name again?"

(This conversation is kind of sketchy and concerning! Probably not in a maleficer-murder way? But Marian is nonetheless on alert and wants to take down notes about it.) 

"Ghassan. I'll stop by again on a weekday, during my free period. Sound good?"

Ghassan is wondering what kind of medical emergency allows for the nurse to step outside the infirmary- maybe there's a mal and an honorable person would offer to help. There aren't any of those in the Scholomance. He doesn't.

"....Yeah. Okay, sure." 

She should definitely remember to tell Wen Qing about this kid? .....She probably won't at all remember to do that unless she writes it down, like, in the next thirty seconds. 

"- Uh, thanks, take care...?" 

Most awkward social interaction EVER but it's still way less bad than her entire day today. 

"Take care."

Hopefully she's not about to die of a mal because she was too awkward to ask for help. Ghassan heads back to his room to revisit his recipe.
