Marian eagerly takes the opportunity to SIT DOWN.
(You would think that being a school nurse required less standing and running around than being an ICU nurse, and this might be true if her infirmary had any...seating...other than the stupid cots. However, her feet still hurt.)
She also takes the opportunity to make some discreet observations. There...sure do seem to be some bizarre class dynamics here? The New York group is clearly the elites. She's not totally sure about Shanghai's relative status, but - they're better off than the independent kids? And definitely better off than the random mundanes who didn't know magic was a thing until today. Like - what was her name, oh, right, Wendy.
...right, she should find Wendy and tell her that her stash of Adderall is going to find buyers in the Shanghai enclave. Maybe. Unless getting it from the void saturates the market, but the void isn't exactly an infinite supplier of controlled substances...
Trying to simultaneously track what's medically justified and appropriate versus what will keep Marian herself alive versus what will benefit various other specific students is making Marian's head hurt. She decides to take a break from thinking about it and read titles of library books while she sips her tea.
