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.
A moment later, Addy's nametag is revised with a warning label: Do Not Feed Excessively Powerful Magic To This Amoral Vampire Who Is Kept In Check Mostly Via Magic Related Bribery, Please.
[There's no clear set of rules about who can do magic and how and why. I could give you a good guess about whether or not someone might pick it up easily, but I couldn't tell you exactly why, and I'm not always right. But it works according to patterns. The practice in my world has been overwhelmingly benevolent for years, so spells that accomplish positive effects are easier to learn and create, and spells that accomplish negative effects are harder. Unless you get a lot of people very determined to wreck things, it should be the same way here, and even if you do it'll take a while for the balance to shift.]
"He's a Whistle," says Amariah. "There's two people named Alice here who are not alts of each other - the other's Golden's precog. I bet Kas and Petaal would make a good control for looking at Sue and Ivy to see what's just them and what's the results of the dream, too."
Stella reports to Matilda: [I don't want to introduce your magic at this time, but I'd like to revisit the issue in a few more years when my empire's more entrenched and has more than a few million people in it and Earth is a nicer place to live. Jane's got a node in your world so I can contact you anytime, right?]
On the opposite end of the pile from Kas, the Joker is curled up with his arms wrapped around Sue, and both of them are looking at her. Hard to tell if 'speculative' applies.
Girls just aren't labeled in her head as potential partners. Maybe not in the same sense that, say, chairs are - chairs are not people, among other important differences between them and girls - but in about the same sense that children or - or buggers aren't.
She has an agony beam installed - it's standard issue, she got it stacked up right with everything else. She hasn't tried it yet. Or she could just dig her nails in a little where her hands are pressing into his back. Either, both, what's his preference?
