"Aha," says Jarvis. "Lucky you."

"Are you even, like, constitutionally subject to addiction-in-general? Or is that not a problem on your neighbor-world? We should name it. Jarvis, you wanna name where you came from?"

"As far as I'm aware, I am not subject to addiction in the first place, and if necessary I could modify my processes to counteract the effect," says Jarvis. "Is there a naming convention in place?"

"Bells have been naming our worlds pretty much according to whim or, where applicable, imperial theme. I called this one Sunshine in spite of Minus's charming suggestion of Hell-Orifice. Shell Bell's from Atlantis, Golden from Aurum, Angela from Samaria, Amariah from Alethia, Stella from Eos, and we don't have a name for the world that has the one of us who's ten and was written in by her Whistle yet."

"May as well call mine Sunshine-Two," says Jarvis.

"Oh, don't let's number them. If they're similar enough to warrant group naming it could be Solar or Sunlight or Helios or something."

"I can't help thinking that after a few of those, it will be hard to keep them all straight."

"I don't think numbers are an improvement, there," Bella says.

"Helios, then, if you must."

"Helios it is."

"What's mine, then? Apollo? Ra?"

"Whatever you'd like to call it, although we are doing a sort of a theme so something like that would be ideal. I wonder why there's this entire family of worlds with the same kind of vampire and magic and whatnot. And Sherlocks everywhere. No two Bells are from worlds more similar than both being Earths at around the same time."

"We Sherlocks do seem to cluster more closely," Minus agrees.

"Except Shell Bell's, who's as far off from you guys as Shell Bell is from me. Farther. Nonmagical world, she's a girl, she's actually her Tony's twin, there's no Jarvis. Weird."

"True," he muses.

"Maybe one day Alice will make Stella a coin so big that she can unravel all the secrets of the multiverse, and she'll share," snorts Juliet.

He laughs.

"Anyway. Jarvis, since you are effectively immune to addiction and you don't do invocations is there any further reason for you to be cautious about magic-doing?"

"Not especially, but it is a little more difficult for me because I have no way to manage most of the physical requirements."

"Is collaborative casting a thing?" Juliet asks.

"Not universally."

"What does that mean?"

"It means it is varyingly possible, with varying effectiveness, across the different traditions I have researched."

"Huh. Well, that's something to look into. Giles, do you know anything about it?" Bella asks.

"Enough to support his analysis."
