Today, after eight months, she does.
She makes sure that Sherlock and Tony are both awake, finds that they are but do not want to join her in the bar today unless she finds something interesting, checks her coin supply and finds it sufficient, and steps through.
[Yep, could you see me anyway? I do that when I'm teleporting somewhere unfamiliar. I apologize for appearing in Tony's room, but I didn't know where he was and the way the teleportation works is I specify a unique location, like 'near Tony'. I have one of him on my world and I heard that this world had one too so I have come to be sociable, but since he doesn't seem ready to receive visitors right now I thought I'd go through you, figuring there was probably a you too.]
[I don't know. Do you know how to open a door to Milliways at will, like the other Jarvis? Because if you don't, I have as long as my friend is willing to hold the door for me.]
[Then my time here is limited unless I want to let my friend close her door and wait until I find a door myself, which has been known to take up to a year and a half.]
"Mine, you mean? I call it Atlantis, and it has a one of you in it, only he's my age and he has a twin sister. It's in the future relative to here, and it was until recently a pretty nasty totalitarian state where it wasn't just post-apocalyptic, but I have since acquired magic and fixed the place up a bit."
"Oh, did I leave that there? This is only an illusion crown, I left my real one at home." She waves her hand through it by way of illustration. "Yeah, I go around wearing a crown, calling myself Empress of Atlantis, putting bad guys on the moon. There's lots of me, in various worlds, too, and this is a thing we do is take over worlds and be nice to them."
"One of me did wait until she was twenty-three, but she had a bit of a setback with the previous rulers of her world, she didn't have such nice magic to work with," says Bell. "And if you'd said that to her, given that she still looks seventeen, she'd raise one eyebrow like so -" Bell demonstrates - "and say that she's in her forties, so you've only made a lucky guess that I am in fact nineteen as of recently. So what? I'm doing a dramatically better job than the last dictator. He was evil. He propped up a system that had teenagers killing each other on live national television for populace-quelling and fun and profit. Your alt was on the show, so was his sister, they both won but they had to kill all the other contestants to get out alive."
"Yeah. I wasn't on it, I got picked in the lottery once but my district had this system to train particularly - likely-looking kids to go, so everyone else would be safe and they'd have a reasonable shot," shrugs Bell. "But anyway. I'm glad I didn't wait to take over the world until I was the right age for an empress. I was ready to do it when I was thirteen, if I'd had what I needed then. I probably could've done it younger, but thirteen is when people started recognizing me in Milliways and saying I looked like any of various Her Majesties, and then I knew I could."
"Yep." She pauses. "I wonder if you have an alt of the last president here, too. There were two other worlds that had yous in them and also had hims. You never cloned yourself, did you? In my world you've got a twin, she's called Sherlock, but in the others you clone yourself when you're twelve and get alts of Sherlock instead, only mine's the only one who's a girl."
"Did you even think about it? But anyway, clearly alts don't all come together since you haven't got a Sherlock - I've met a Sherlock without a Tony but he had one originally, his died and his Jarvis too but then another Jarvis copied and another Tony installed the copy in his world so he'd at least have him, he was a wreck about it, the matched sets are all really close... Anyway, the last president of my world was named Coriolanus Snow but he had a different name in the other two worlds, Obadiah Stane."
