"I met a person called Sif there and another one called Heimdall who appeared to have been supervising a previous conversation without having been present? Is that informative?"

"I don't tend to get mythological references and so on, I have a spotty and culturally impoverished education. I've been going to Milliways since I was six and staying until I ran out of seashells to trade for food, so in some ways I'm very cosmopolitan albeit without much information about what things are and are not common across worlds, but I spent the rest of my childhood in a beach town pretending to be slightly crazy, attending an underfunded school designed to turn out docile fisherfolk, working on a clam boat, and generally existing in a context that has lost all its previous ties to Earth history that isn't a fictionalized version of the Roman Empire."

Tony blinks. "Okay, that's impressive."

"...Which part?" Bell asks, tilting her head.

"Being an empress, on a resume like that?" he says.

"Oh, I could stay in Milliways for a long, long time if I brought enough seashells and didn't eat much," says Bell. "I talked to everyone and read a lot and watched a lot of video and learned everything I could. And after your alt and Sherlock put me on their tab instead - they're rich, you got a lot of money for winning on the TV show, everyone else outside the Capitol was dirt poor - then I stayed for months instead of weeks until I faked my death and stowed away on their train to move in with them. It's possible I'm actually twenty now by subjective time, but I've never added it up."

Tony shakes his head. "Yeah, no, still impressed."

"All right, be impressed, then," laughs Shell Bell. "So do you want to come meet Darcy?"

"Darcy... your superhero friend?" he hazards.

"Yeah, she has a magic space hammer that only lets the worthy lift it that she calls Mewtwo because she can't pronounce whatever its real name is and she is learning superheroing from her friend Sif."

"Mjolnir," supplies Jarvis. "In all likelihood."

"That doesn't sound very much like Mewtwo at all," Bell remarks.

"Cultural reference," says Tony. "To a videogame. Jarvis, how do I explain Pokemon?"

"A question for the ages," Jarvis says dryly.

"I know what a videogame is," says Shell Bell helpfully. "I've never played one, but I've heard of them."

"That's a start!" says Tony. "Mewtwo is a... rare and powerful imaginary animal from a videogame about collecting imaginary animals and making them beat up other imaginary animals for you so you can collect those too."

"That actually sounds kinda fun," says Shell Bell, "if the imaginary animals don't spend the whole time being miserable about beating each other up."

"Nope, as far as I remember, they're mostly weirdly cheerful about it."

"That's good, then. Now I get Darcy's reference. Are we gonna go introduce you or talk about video games?" Shell Bell giggles.

"Video games," he says, pointing at her emphatically, "are serious business."

"Perhaps I'll borrow one from Milliways on my way home and collect some imaginary animals."

"Anyway," he says, "I think I'll pass on the interplanetary travel."
