"...And I would also feel awkward filling in for a dead me," Tony points out.

"That too," Shell Bell acknowledges. "The relevant Jarvis was pretty even-keeled about it as far as I could tell, but I guess that's a little different? Also the worlds are closer neighbors -" She gestures at the relevant cluster of Sherlocks and the one displayed Tony. "These three all seem to have the same kind of vampire, similar magic systems, that sort of thing, my set's the odd one out in more ways than one. All the Bells are from very different worlds. The most similar pair are Stella and Golden, who had identical histories until they were seventeen, moved in with their versions of our father, and Stella encountered magic like what I have now and Golden encountered a different kind of vampire."

"There are a lot of vampires in this story," Tony observes.

"Yeah, there really are. Stella thinks Golden's kind is neat so she turned her boyfriend into one." This is punctuated by illusions of all three named parties - Stella, Golden, and Alice. "This guy's template also crops up a lot. We call them Whistles - bells and whistles, it's apparently a saying some places? - and three of us have them."

"He looks vaguely familiar," says Tony. "Not that that means anything."

"Nah," he says. "He kinda reminds me of somebody, but I don't think I know him."

Shell Bell shoos all the illusions except, again, her Sherlock. "Maybe I'll see if I can teleport to him if you get bored of chatting before Darcy gets bored of holding the door, just in case. I like knowing about all these far-flung alts."

"Just try not to walk in on him naked," he says, amused.

"It's possible I should work out a way to boost the teleportation power so it can live with complicated algorithms like 'on the far side of the nearest door to so-and-so', but that doesn't rule out the possibility of somebody being naked in that room," Shell Bell says.

"You could add an optional constraint that fails if there are any naked people visible from the landing point," he suggests.

"That's a good idea," says Bell. "I will." She does, and nods to herself.

"You probably don't want to teleport into anybody's bathroom while they're using it, either," Tony muses.

"I haven't actually had that problem because of the way the teleporter interprets 'where so-and-so is' - I mean, you would have noticed if I'd appeared literally on top of you, and bathrooms are usually too small for me to show up in one with a person," Shell Bell says, "but it's probably worth installing anyway, in case I'm ever hunting for somebody with unconventional architecture."

"...I am suddenly really glad you didn't come looking for me two hours ago," says Tony.

Bell laughs. "Do you have," she asks, "an enormous bathroom?"

"Yes," says Tony. "Yes I do."

"Then I am also glad I did not appear two hours ago. I apologize for not having added all these tweaks to my teleportation power before. I copied it directly from Stella and I have the impression that she usually knows plenty about where she's going and doesn't need this installed on the magical level. And is only visiting people she's already put on the brainphone network so she can call ahead anyway."

"Brainphone...?"

"Telepathic phonelike thing?" says Shell Bell. "It's very handy, do you want in? I've already added Jarvis to announce myself when I first arrived, you could talk to him wherever without making a sound."

"Gimme," says Tony. "That would be very useful."

[Behold!]

[Ooooh,] says Tony.

[It also does text channel. And busy messages that pop up according to arbitrarily complicated algorithms, although since in this world I've only added you, Jarvis, and Darcy, I don't think you'll need those unless you want me to throw a dozen of your friends in too.]

He laughs. [My friends all have real phones.]
