She planned for that, at least; they're not school books or anything. But she wants to get this potion right,and more importantly, she wants to have it done before exams. So today she can be found in the Magic Box, digging through the herb selections.
"Ugh, least organized spices ever," she mutters to herself.
"No problem, been there." She pricks her finger on something-or-another's thorns, swears violently in surprise, and is promptly distracted by the sight of her goal. "Yes! Finally, Lethe's Bramble." She snatches it, standing victoriously, and promptly smacking her head on the edge of the counter. "...ow."
She isn't about to go into much detail. Most of the teenage girls who come to the Magic Box are here to giggle and buy 'healing crystals' and feel edgy, and Alli has no desire to explain the memory aid potion to some random Wicca wannabe with no magical abilities whatsoever. If the girl sounds like she knows what she's talking about- maybe. Alli could use some new ideas at this point. But 'rose quartz' isn't much to go on either way.
She rubs her head gingerly. "Think I'm good, but thanks. Just surprised me."
"I mostly meant what you want it for, although I'm curious about the other thing too. I need rose quartz for like ten things, none of which I want to do this week, but if I don't spend my allowance on magic stuff now I'll wind up with none left when I do get around to the spells."
It usually runs in families, but magic is hardly known for its stellar consistency (see: Alli's current potion-making struggles). And although both Alli and her sister have the knack for it, their mother does not, for which Alli emphatically thanks her daily deity regularly.
"Have you come here before? I don't think I've seen you."
Or possibly a painting heist. She thinks.
"You see what I mean, though?"
She looks slightly rueful. "I've probably put more time into the potion that I would into exams, but come on. Magic or Great Expectations? It's not even a contest."
Or at least 70% odds, instead of 40%.
She stops on the next page with a triumphant sound. "Aha! Potion recipe staring time?"
She goes over the recipe for Soph. There's quite a few steps, involving at least two Latin chants, extremely specific stirring directions, and bundles of precisely measured herbs. Some of it's smudged and hard to read, and the whole thing's rather... vague, in that way magic books often are.
"You see why it's such a pain in the ass?" Alli asks rhetorically.
"Yeah... like I said I haven't got into potions but I have got a little bit into Latin, I switched into it a few weeks ago when I discovered that there is almost no Spanish in spellbooks, and I know almost none of it so far, but is that conjugated right?" She points at a verb.
"...No. No, you're totally right. That's the wrong tense. Damn it all. I didn't think to check the Latin- I thought I measured something wrong-" she starts to scribble things down on a spare sheet of paper from her backpack. She's on her third year of Latin; she's not the world's best student, but she's past the basics. "And this is in the dative instead of the accusative, and this should be plural... who wrote this, they should be banned from magic."
She finishes scribbling out her corrections and looks up, pleased. "Got it!" She looks at Soph. "You're the best. I owe you potion if it works." To Bella, she adds, "Did you want to try a spell with not-your-sister? I can show you the glitterlight spell, or something."
She poses (unnecessarily), says "Nitidi!" and sweeps her arm through the air. Sparkles follow.
Alli shrugs. "There isn't form. It's just- an incantation. It might just not work? One of my books was written by-" she puts on a Snobby Scholar Face, "-by an Expert in the Field of Magicks Who Tragically Lacked The Power To Himself Become a Practitioner." She reverts to normal. "Or something like that. But old person talk for 'knowing how to cast spells does not mean you can cast them', anyway."
"My sister left some old books lying around. I found them when she moved to college and took her room. They were mostly little things like that one. Say something, see cool but mostly useless effect, try the next one. Good for beginners who are skeptical that Magic is a Thing, anyway."
"Depends a lot on the potion. And the books are awful sometimes, it's like- imagine you're trying to make dinner, and you are making chicken from a recipe. And you do the marinade, or whatever, and then the last step is just 'cook until done'. No time frame, no temperature, no nothing. That is potion making."
"All clear!" she reports cheerfully. "Mom's still at work, I guess. Come on, I'll show you the Witching Room."
The 'Witching Room' turns out to be a small room upstairs, too small to be a bedroom but with no obvious alternate purpose, tucked at the end of the hall to one side of Alli's bedroom. It's long and thin and the front part is pretty obviously being used for random whatever-we-toss-in-here style storage, but Alli navigates a path between boxes with the ease of practice. "Voila!"
The back part is cleared out, with boxes stacked in front to block the view from the front of the room; there's a small, battered bookshelf containing occult books and various spell components, and a small cauldron on a bunsen burner. Alli starts rummaging through her ingredients. "Okay, the bramble needs chopping and the thyme needs steeping, who wants what?"
Alli then occupies herself digging out and measuring the remaining ingredients from her probably-has-a-system shelving.
Once the ingredients are ready, they get to be added to the thyme-water. In a particular order, in particular quantities, and each with a phrase in Latin from Alli's spellbook, as corrected per their earlier library adventures. Eventually the potion has turned a deep, deep purple (which is mildly confusing, as nothing that went into it actually was that color). Alli stirs it three times counter clockwise, sighs morosely and sets an alarm. "And now to do that every fifteen minutes for the next six hours."
Alli has no particularly high opinion of homework and is fully in favor of comedic fluff. She alternates between chuckling at the jokes and, when particularly frustrated at Obviously Stupid things the characters are doing, throwing things at the television. She appears, in fact, to have a pile of post-it notes next to the couch for just such a purpose.
