Okay, she knows her epidemiology.  ...That probably means they're good.  She's gonna wander off, then.

The city continues to be a city. Guards chasing a pickpocket. Trendy sweets shop with a long line. Buskers. A group of wizard-style-robed young adults standing in a tight circle doing something. Someone flying overhead! Leaky fountain dripping into the road from cracked masonry. A dog, which barks at her. She's at the edge of the academic district again.

She's gonna watch the wizard-chic teenagers!  And then make her way to the lunch place.

If she creeps up close to peek between the hems of their robes, she will find a large cauldron with weird baffle-y bits sticking up out of it. Weirdly bland-smelling cooking oil glistens on them and drips slowly in. (...actually, the lunch place smells the same way, so this is probably Apprentice Oil)

...Huh.  What're the baffles for?

The students are just gossiping and complaining about difficult coursework, not conveniently discussing their oil-making chore.

Oh, is that what this is.  Okay.  ...There any questions that her semi-dubious command of both geometry/trigonometry and spell design allow her to elucidate?

They're arguing about discontinuous functions and how they are a real pain to cast because they blow up worse than most others if you get it wrong. A girl in the crowd takes the position of 'lmao git gud'. Well, different words but that's the sentiment.

...On the one hand, yeah, on the other hand, ???

"...Discontinuous like rounding is discontinuous, or discontinuous as in there is no derivative nor singular limit for a function f of x when x equals a discontinuity within the range of your function?  Because one of those has a whole damn lot more of my sympathies."
