People keep walking up to her and talking to her when they don't even need to and there are other people who are like right there. MAYBE El's previous life experience with hippie rural mundies and also strict-mana prophet-directed relatives is not fully representative and she can... interact with people here. That would be cool probably. She clears her throat and raises her voice. "Hey, who wants to go to the loo?" It's been long enough that the water will probably have gone through some people.
"I'm languages for sure." Alchemy or artificing might have been fun, but if Alyona's going to make it she's going to have to wring as many spells out of her incredibly inconvenient affinity as she can manage. "Surprised you're going with artificing, if you're into paints."
"Oh, I'm not much for alchemy. My mum was, but she passed on when I was too little to learn very much, and I've always found making things with my hands more natural than brewing and mixing things. Maybe while I'm here I'll find an alchemist who makes interesting magic paints," she says thoughtfully.
"Worth asking around, at least. If I run into anyone like that, I can send them your way. ..Except I don't think I actually got your name?"
"Thank you, that would be nice of you! I'm Luna. And you're probably Alyona, I think, unless you're Sophie?"
One can pee into the void, and this is even recommended if you need to go in the middle of the night - disadvantage of the ceiling rooms - but as long as she is here with backup El checks out a stall to pee into not the void. (Directly. The school probably dumps it all into the void later on.) It needs more paper from the cupboard but this is as good a time as any to restock.
Luna takes this opportunity to use the loo, too, in between serving as backup. She also takes a bit of toilet paper, while she's here, since it is paper, after all, and might be workable into some craft she hasn't yet devised.
"I think you can't actually take that out, it's not all real, if it were people'd steal it and turn it into spare pillows or something."
"Oh, that's a shame," she says, and puts the toilet paper back. "There now, I'm sure you'd be very good at lots of different things, but here is where we need you the most," she reassures it.
Well that's adorable.
"I am almost certainly ending up in languages track but there's a chance I'll go creative writing instead."
All in all a successful trip to the bathroom. El leaves with full water bottles and several names to put to faces and no less bewilderment about why all these people are willing to talk to her, and heads back to the cafeteria with them to try her luck once more.
