"...Let's go with yes," he says uncomfortably.

"What all did Elizabeth tell you about our world and how it's shitty?" asks Bell.

"That it's shitty. And we should talk to you about how shitty it is."

"Yeah. Well. That guy's alt is President of our shitty world. If our actual President showed up here he would need to be made dead, consequences of outside grudges brought into Milliways be damned, because we're all three of us recognizable to every person in our country and it would not be smart to take a chance on him deciding that people with reason to hate him having access to Milliways is fine and dandy."

"If you can't guess the rest, you don't wanna know it," he says. "Maybe yours is different."

"Not by much," says Sherlock.

"...I'm pretty sure Obie isn't an evil dictator?"

"They could easily be different in any number of ways. I happen to know that I come in vampire, for instance. But frankly I'd rather not involve your - his name is Obie? There's a difference, ours is called Coriolanus Snow - in anything that would put us in the same room again. At all." Pause. "Unless he's good enough and a good enough actor that assassinating ours and replacing him with yours to avoid triggering deadman switches would make any sort of sense? Probably not, but it's worth floating...?"

"No," says Tony.

"No," says Elizabeth.

"Definitely not," says Sherlock.

"Didn't think so."

"...Also, back up, vampire? Good vampire or bad vampire?"

"I haven't met her," says Bell, blinking. "I haven't met any of me. Milliways and I have this inconvenient relationship where it's willing for me to come here sometimes but it's not nearly as convenient to my wants as other people seem to find it. But I met a friendly werewolf who lives in the world that vampire-me sort of secretly rules. And he seemed to think she was fine, or at least an obvious improvement over the previous secret vampire rulers of that world."

"Huh, okay," says Tony. "We have vampires in our world but they are, like, all assholes. Pretty sure they don't secretly rule anything, either."

"I think my vampire alt was notable for not having eaten any humans, but she still had not eaten any," Bell says. "According to the werewolf I met. If the ruling things is secret how would you know if yours do?"

He points at Sherlock.

Sherlock smiles faintly.

Bell shrugs. "Reasonable answer, I guess, I don't have a lot of detail about how secret the secret is. So. You wanna help us?"

"Yes," says Sherlock.

"I think I'll leave you guys to it and go placate my future husband," says Elizabeth.

"You didn't want your entertaining advice first?" Bell says.

"Later," she says cheerfully.
