She finds that mildly irritating for a whole different set of reasons, but it's such an improvement over the alternative that she lets it be. She's very careful not to seem as though she's taking advantage of her new-found position. She demands nothing, and makes only a few careful, diffident suggestions. This will not last forever; no need to burn bridges.
And of course, whenever she receives an email from the Slayer, she responds promptly.
"Uh," says Soph, "if the rhinestone moves, you go with it. The rhinestone exists all the time and prom doesn't, so you don't - wink out, when prom's over -"
"Oh my god!" squeals Minnie.
"- and the rhinestone doesn't have anything to do with how you died so it might make it so you don't, uh, get so mad. Um, Bella."
Minnie reaches for the rhinestone but can't quite touch it. "You're - you're not gonna -"
"We could destroy it. If you weren't so personable I'd do it."
"N-no -"
"But when you're not mad you're a - wronged teenage girl."
Minnie sniffles.
"The question becomes, where do we put you, and can you behave, detached from prom, or will you keep getting mad and killing people. You will not kill more people and get away with it."
Minnie trembles. "So - so pick up the rhinestone and - and -"
"Yeah," says Bella, "that's what I'm thinking."
She picks up the rhinestone.
"I will crush this if you go out of control," she warns.
"I know," murmurs Minnie.
"John never existed. I snuck in without a date."
Minnie blinks at Bella.
"I don't care!" she crows gleefully, flinging her hands into the air, colors supersaturating.
Bella breathes a sigh of relief.
"Congrats!" Alli says with a smile. It's sort of vaguely directed at both Soph and Minnie. "So... hi? I'm Alli."
"Soph, what's her range from the rhinestone?"
"Put me somewhere interesting," says Minnie. "I can be unobtrusive and invisible, look." She winks out, then back.
"Somebody might think your rhinestone is pretty and carry you off," Bella points out. "I think for the time being I'm just going to keep you on the back porch, but we can figure out something to keep you entertained. Soph, Alli, you good to clean up here and go have fun dancing while I carry Minnie away?"
"Yeah. Wow, what time is it, it's got to be at least nine by now." Soph starts collecting her materials.
Alli trots over and gives her a hand with cleanup. "Nine fifteen," she reports, "but we've still got a couple of hours to dance." She looks at her cup wryly. "Probably need a new glass of punch, though." She looks at Bella and Minnie. "You guys gonna come dance...?"
"I'm only substantial when I'm mad, anyhow," says Minnie. "I don't think I can really dance with anybody."
"You guys have fun, though."
"Man, the cute boys are all going to think we're gay, aren't they." Soph tucks her magic stuff into her sash.
"Meh, whatever. Doubt that would stop them. Remember the goons at the door? But. Everyone here is also here with a date. It's a challenge!"
Witchery gathered, Alli disposes of that of it which is disposable (mostly the herbs) and hands the rest back to Soph. "Onwards!"
