Bella giggles, and out they go. "Bye, Jarvis," she adds before shutting the door behind her.

It's a quiet walk. Minus takes the opportunity to hold Juliet's hand the whole way, while Plus is presumably lurking along somewhere nearby.

"Don't go near the porch," Bella thinks to inform Plus when they approach her house. "Sunlamp bulbs and a motion detector, you see." She kisses Minus goodnight from a safe distance.

"I don't have the faintest dream of a clue."

"Found an alt of Sherlock in Milliways. Not Shell Bell's, and not the one who matches the Tony who visited either - they've both gone home now, by the by, Jarvis is all installed. An unrelated Sherlock who is also a vampire but this one has a soul."

"...How'd he come by that?" inquires Giles, adjusting his glasses.

"Some manner of pre-arranged... thing. He still has his Tony and Jarvis, so I imagine they were involved. You can come by and see if he'll tell you, this evening. I'm doing sparring in place of fire wand while he's visiting because I can make unusually good progress with the both of them."

"I think I will."

"I'm making steady progress on the wand, though," Bella says, pulling out the demonology text of the day. "Did you ever ask Sherlock - we're distinguishing them as 'Minus' for the local and 'Plus' for the visitor - did you ever ask Minus your question about how he came by the number twenty-six?"

"No, it slipped my mind."

"Oh. Well, I asked him. He followed a Watcher around for a while is how. It wasn't you, and the Watcher's fine and never noticed that he was there."

"That's... reassuring," is the word he chooses after a moment.

"Compared to the source being you or the Watcher not being fine, or compared to Sherlock having learned the maximum historical Slayer lifespan some other way?" inquires Juliet.

"Yes."

"Ah," she giggles.

He smiles dryly.

Studying happens, and study hall ends and classes happen, and more studying happens, and then Bella says, "Well, I presume you remember where the house is, as you have been there before and also technically own it."

"You presume correctly."

Her phone beeps. "Well, if you show up any time after sunset you can come watch me sparring with two Sherlocks and try and guess which is which!" she says cheerfully, and off she goes.

The sparring's already underway; Bella's worked her way twelve seconds into a one-minute sequence and barely manages a "hi" when Giles walks in between all the ducking and parrying she has to do to keep up with a set of Sherlocks.

It takes about twenty minutes - including four pauses for written revisions - before she gets all the way through the sequence and pauses to catch her breath and sip from her water bottle. "So, this is Giles," she says, "Giles, one of the Sherlocks is Plus, and the house is now Jarvis instead of just a regular house."
