Bella is hanging out in a Jarvis - the familiar one - handwriting a nonaggression proposal-slash-bribe. Has to be handwritten. Damn fussy demons. At least it's okay for her to conjure rather than personally harvesting the weird ink she's supposed to use.
"Your sister, like yourself, has a bloody magical immunity," says Sherlock. "To torching, interworld travel, and any coin above a pentagon, as well as a haphazard assortment of local spells."
"What? No, I could make her torchable right now, I can see it. I'm not going to because I have no clue what we're dealing with, but I could."
"That's what the magic is telling me, anyway, do you remember me incredulously reporting this discrepancy before?"
Since the weather dispute is getting nowhere, he spends a coin to raise the local temperature to something Soph would find more pleasant.
"Well, she looks torchable now, and I have no memory of her now, and I still think it would be easier to edit Jarvis's records and a handful of unprotected memories than to hack into my brain."
"Jarvis's records, the physical contents of your bedroom, and my internally consistent recollection of the past eleven months, all at once. Yes. Fucking trivial," says Sherlock.
"Oh, come on, I could do that with a star, maybe an evil, if I had any reason to want to," says Juliet. "You know what I couldn't do with a star or an evil, I couldn't edit my brain, I'm next least friendly-headed after Golden and not even Stella can make mental edits!"
"And who, in this scheme, do you imagine got their hands on an evil and decided to donate you an extra sister in case you were running short? The sun hasn't exploded recently, so they would've had to know how to use it, to boot."
"I don't know! Who would have decided I ought to forget I had one, if I did?"
Bella clenches her teeth and nods. "What'd you have in mind? I like my crystal ball, but it's not simple to interpret."
Bella chews her lip, but then blinks away and back, bearing her crystal ball - apparently she still doesn't want Soph in a Jarvis. She holds it in her hands.
"Today is Voyeurism Day, apparently." Bella hands Sherlock the ball.
"Apparently so," he says, and passes the ball to Soph.
Bella's not happy about Soph handling her birthday present, either, but she compromises this far.
"Huh," she murmurs. "I don't know what it means..."
"The fellow in the shower worked at the Sunnydale hospital," says Sherlock. "Perhaps we should find him and apply questions. Or better yet, spy on him from afar."
"You recognized him, or was there, like, a clue in the crystal ball?" Soph asks, offering Bella the crystal ball casually till she remembers what's going on and flinches.
