She checks some things out. They hit the road.
"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.
"It's not super clear, but I think pretty damn fine. Let me know if you get tired or something."
Bella starts shredding the bramble methodically.
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."
"Yeah, no worries, I'll bring some in tomorrow with a report. But- sunset? What, does your dad hate clocks or something?"
"Nah, it just gets dangerous around here after dark. There are statistics and everything."
"Sure, plenty of places get dangerous at night, but most people still have curfew at seven, or whatever," Alli laughs. "But whatever, if it works for you. How long do we have? I don't even know how far away you guys live."
"Well, you're welcome to hang out if you'd like. But my awesomely cool plans for the afternoon were 'magic and homework and TV'. So, if those are not up your alley, suggest away?"
"I watch damn near anything, actually. But I default to faster-paced stuff. If I wanted to watch people stand uncomfortably and revel in being awkward as shit, I'd go to class."
"Oh, I don't care, I'm just going to actually do homework. I'm not so much a TV person."
"Well, maybe something's too loud? Or someone has a reeeeeeally squeaky annoying voice? Have a veto anyway, veto-use optional." Alli starts flipping through the channels.
