Margaret Peregrine is a high school sophomore. Most of the time, she's either at school, at the school robotics club, at the school chess club, or doing schoolwork. Today, she's cleaning out her late great-grandmother's attic.
"I should get home; my parents will start worrying if I'm out much later. Thanks for showing me your art and your house!"
Home and zzzzzz. The next day she accumulates as many worms as she can find before her parents get home.
Timer: start. Mad science: commence.
These two get stuck in a cup but otherwise left alone. These two get repeatedly harassed with the eraser end of a pencil but not injured. This one gets stabbed and left to bleed out. These two get stabbed and healed, then stabbed again and healed again. These two get stabbed once and healed five times, then stabbed again and healed another five times. And this last one gets cut in half and then healed repeatedly until it either dies or appears to have stabilized (she keeps count of how many tries this ends up being either way).
Repeated healings: useful. All the living worms and worm-corpses go out the window. The rest of the evening is spent prepping dozens of copies of the diagram and checking the late-night bus schedules.
Three hours after her parents have gone to bed, Margaret sneaks downstairs, memorizes the location of her mother's keys, grabs them, and slips out of the house. There's a bus that goes close to her mom's vet clinic, and nobody works there overnight.
"Being in bed sounds pretty nice right now." she says truthfully. She got a bit of a nap earlier, and she's too keyed-up to sleep on the bus anyway, but it's still later than she's used to being awake.
"I have to stop by my mom's vet clinic and make sure everything got locked up properly; she's worried. Better me than her, though, she works crazy hours already. How about you, what's keeping you up?"
"Oh, hardly ever. And I'm happy to do it, really, she's a great mom. Swing shift sounds rough."
Has she considered that maybe Margaret oughta be ashamed for bad-mouthing her mother like that? Ugh.
Margaret gets off the bus, walks the last little way to the clinic, and lets herself in (her mother had, of course, locked up as always). She slips into the section where the overnight patients are kept, a room full of kennels with unhealthy cats and dogs sleeping on fluffy blankets, and starts checking charts for something old with a physical injury.
She slips a diagram copy into the kennel, mentally runs over her incantation a few times with "chien" as the species, and recites it.
Her first enchantment spell should be to make something glow; that sounds pretty simple and safe. In the meantime she can work by the status lights on the equipment. Her backpack is filled with meticulously stamped papers; she has enough for two more casts on the schnauzer, and for three on every other cat or dog with a physical injury.
She goes one at a time through the injured ones before looking over the sick ones. She includes the ones with parts missing, though she'll stop at one casting on those if the first one either does the whole job or doesn't seem to do anything. Used-up diagrams go in a different backpack pocket.
