To start with, there are now eight Bells. Pattern isn't bringing anyone besides herself, and Aegis no one besides herself and her Whistle, but everyone else -
Between Alice, the Joker, the rescued Queenie, Kas, Micaiah, and Sue, plus Ghosty who Amariah picked up on her way home, that's seven Whistles. (Stella thinks ahead: there is a soundproofed orgy chamber away from the main party awning. With a few nodes off of it in case more than one orgy forms; she can think of at least two other likely ones.)
There's an equally absurd number of Sherlocks and Tonies if you count them together. They have Juliet's matched set, Shell Bell's matched set, two other matched sets from Bell-less worlds (one with souled vampire, one both human), a stray Tony, and a stray Sherlock from Downside.
Amariah grabbed a random Libby on top of the random extra Whistle, but at least she's not incorporating anyone from home.
Golden's bringing much of her family and many of her friends - although Edward is staying home, that still leaves Elspeth and Jacob, Alice and Jasper with little Brandon, Rosalie and Emmett and little Henry, Nathan accompanying his mate and their child Kerron, Esme and Carlisle and their Lily, Addy, and Elena who'll get to see her brother. Golden claims that this is a conservative list and she could easily have produced another twenty enthusiastic guests. Stella doesn't doubt it. She puts up a few signs reading Please Conduct Adult Conversation Only Via Brainphone. Little Half-Vampires Have Good Ears And Perfect Memories. As a last-minute surprise, Golden has taken Elspeth's suggestion to bring Edward's deceased mother Elizabeth, too.
Juliet has, on top of her boyfriend and his - progenitor? - her tiny Libby, James, a tagalong thereto called Virginia, and a ghost called Minnie, plus Giles.
Angela's list is more modest: her, her husband, and their friends Alleluia and Caleb.
Shell Bell is responsible for half the Sherlocks-and-Tonies all by herself, a tagalong called Pepper, and also someone called Darcy and also Matilda. (Shell Bell is also the reason Angela is not inviting her brother-in-law.)
Stella herself is responsible for inviting Libby, Orfeo, Chris, Mary, Anna, Sandy, Eights, Chainsaw, Lazarus, Kolya (who is informed that it would be awfully inconvenient for a majority of Bells to all have to coordinate on pretending he doesn't exist when only one of them has even met him to be able to identify him in the first place, so he can simply stay home if he's planning to be hidey), and Bridget.
Stella sets up a name tag system. Everyone will have a tag stuck to them. Solo persons - a minority - will just have their names. People with template names and nicknames will have both stamped on automatically. ("Hi! I'm a Bell, and you can call me Stella!"; "Hi! I'm a Whistle, and you can call me Alice!" "Hi! I'm a Sherlock, and I don't have a distinguishing nickname yet but as soon as I pick one it will appear here!")
She conjures up a nice buffet of food and beverages which will stay its correct temperature until consumed, and assorted synthetics for the vampires (labeled not for human consumption), and dishes and flatware (all glass; even some of the food-eating guests might dissolve anything else) and fusses with the awning opacity until it lets in just the right amount of sun, and, what the hell, she throws in a stage in case Angela wants to sing or she decides to play the flute or someone decides to pentagon some other performative skill to entertain the crowd. She makes sure there are enough bathrooms for all the people who still need bathrooms.
She puts out a few tables here and there with little bowls of squares and triangles - a mix of her glowing red and Alice's shifty black - in them for everyone's convenience. She accumulates coins in those sizes faster than she generally uses them and has a great many, so there are plenty for anyone to dip and wish if something comes up. She double-checks to make sure the Martian ground rules prohibit any misuses available for those size coins.
Jane gets one of those high-tech holographic projectors, on wheels, which she promptly manifests in, drives around the floor, and makes faces through.
"So," says Juliet. "Nicknames. Many of you are nigh-indistinguishable - at least to those of us who aren't Sherlocks - and not having different names doesn't help."
"It's the Sherlocks who seem to vary," says one of same. "Vampire, different vampire, human, different human, and then..." he waves a hand vaguely at Strat, "you. The attached Tonies are not so easily distinguished."
Shell Bell clearly has a favorite Sherlock. There may be some leaning and gazing going on between moments when she's not addressing the group.
"Whistles usually just get outright named by their attached Bells, but half of you don't have attached Bells," says Juliet. "Besides, I can't think of anything good."
"Yes," says Sherlock, patting Bell fondly on the shoulder, "that is the trouble. No one can think of anything good."
"Oh, I don't know," says another Sherlock. "'Plus and Minus' wasn't bad. But the rest of you can't describe yourselves easily by your formative soul status."
"And three of the sets come from eerily similar worlds, so there's no playing on that theme. And I don't think my Sherlock and Tony want to pick up on any of the titles the media invented for them."
"I'm beginning to see why Jarvis was so tempted to just outright number the eerily similar worlds."
"Let's all take a moment to be thankful that we don't have to assign distinguishing nicknames to the Jarvises."
"Unless at least two of them start being capable of showing up to parties and getting mixed up, yeah," says Juliet, "not a priority."
"A friend gave it to me, after the guitar." He snorts. "Yes, there's a plan: let's all give ourselves Downsider nicknames."
Shell Bell shrugs minutely. "They do have a certain aesthetic to them. Although I think I would have kept Bell instead of Shell if it hadn't been for my special circumstances."
"I knew - well, strongly suspected - that my Sherlock had resurrected me. So Shell decided that she was Shell and the live one was Bell. Now I'm both again, of course."
"Maybe insofar as you don't have your own characteristics you could come up with a shared short list of things that you'd be able to put up with as nicknames, then pick them out of a hat. Except my Sherlock, who doesn't seem to want a new one."
"Mine mentioned it specifically on the way over," Juliet says. "I guess 'insofar as you lack distinguishing characteristics' is mostly for the quartet of non-Iron-Man Tonies anyway, although yours doesn't seem to have yielded a nickname."
"We probably shouldn't just call you 'girl', should we," says Shell Bell to her Sherlock who is thusly distinguished. "I dunno. Victoria," she tosses out. "And our Tony could be Victor. Or is that as bad an idea as the Panem media's idea of cute things to call you would be?"
"And don't call her 'girl', we have lots of distinguishing characteristics that aren't that one, we're the farthest pair from the middle here."
"Not very namey characteristics, though. Or ones with particularly nice associations."
"I honestly can't think of anything," says one.
