Nods. A slight thawing. (Do they believe her? Probably! Sense Motive is a class skill for police officers.)

Either way, it's not too bad a drive. Chicago looks rather the way it does in their universe, if with fewer smokestacks and more vaguely eldritch buildings, some of which glow and some of which sound like running water. The police station looks like a police station; indeed, it may be a police station in their universe, too, depending on just when the timelines deserved, and the woman at the desk they are taken to looks half as old as the building.

"Superhero bullshit," says the officer bringing them in, and the woman at the desk sighs. "We need the 312X-D."

The 312X-D is searched for. Coffee/water/tea is offered, and while the 312X-D is located, a more complete version of their story is taken down. Two extremely dusty copies of form 312X-D are, at long last, located. Form 312X-D claims, possibly falsely given its size, to be the expedited form for "persons of unknown origin, alternate-dimensional travelers, time travelers, constructs of unknown origin, extraterrestrials and visitors from other worlds desiring official residence in the United States of America'. The form urges them to submit other, more unknowable forms to the appropriate examples of the Department of Immigration (US), Social Security Administration (US), and/or the Illinois Public Health Administration (State) within 90 days. 

It asks for a lot of boring things like name (if known) and age (if known), blood type (including 'unknown', 'other,' and 'N/A') and gender (options are Male, Female, Prefer Not To Answer, and Write-In), as well as more exciting options like 'do you have powers baseline humans do not possess, and if so, what', 'if not native, do you know of other visitors from your world/time/dimension' and 'Are you plotting the overthrow of the United States Government, y/n', as well as the more practical, 'if you are in need of assistance, temporary residence can be found for you for a period not to exceed the latter of 72 hours or 12 hours after residence card is issued per regulation something-that-makes-your-eyes-glaze-over, do you desire such assistance', requests for the names of earthly contacts if any, and a note saying that if you have powers you can contract the American Association of Superheroes for assistance, here is their phone number thank you.

The twins have names! And ages! And blood types, though Isabella's heard of magical girls accidentally changing blood types so she goes with "unknown" just in case it isn't the same anymore. They have genders, conventional ones even! Xander does not but Isabella DOES have powers baseline humans do not possess; she lists it as "shapeshifting, touch-range temporary conjuration, kinetic halting". They know... each other! They are not plotting to overthrow the government of the United States.

And yeah they would love some temporary residence. And to borrow a phone, apparently?

Temporary residence can be provided. It comes with food, by which it means that the motel has a continental breakfast and that if you show up at any of THESE places in the city and show them your currently-being-printed card, they'll let you in, here's a map. (It does not promise to be good food.) And sure, they can borrow a phone!

In that case Isabella will call the American Association of Superheroes while Xander inspects a map and the takeout menus corresponding to their meal options.

Map looks familiar! Some of the takeout places may even look familiar, honestly, these timelines are weirdly similar.

"Hello, if you have an emergency you should hang up and call 9-1-1, if this is not an emergency, this is the Illinois branch of the American Association of Superheroes and my name is Rachel, how may I help you?"

"Hi, Rachel, I'm Isabella, and my brother and I were summoned here by a mad scientist. I have powers, though he does not."

"Hello, Isabella! Welcome to Earth! Are you in danger right now?" This last is spoken in exactly the same tone as the rest of the phrase.

"No, we're at the police station at this point."

"Good to hear that! Have they gotten you the form -" there's the sound of keys clicking as if someone is typing something "- 312X-D yet, and will you need any help with it, or is there some other reason you're calling?"

"We got it, we haven't had any trouble with it, I was just told that it might be a good idea to call for additional assistance? I suppose it's possible they only meant assistance with the form, I'd been imagining something to kick in for our housing situation after the voucher we're getting here runs out."

"Oh, I'm sorry! No, we're happy to help with what we can, I just wanted to make sure that was taken care of first, you'd be amazed at how many supervillains started out with no particular problems except forgetting to fill out forms and reacting badly to the Department of Immigration checking up on them. If you're interested in becoming a superhero, we can provide you with advice on using your powers, getting a costume, operating as a hero, and help getting state funding and recognition, which is retroactive if you operate before it's achieved; we can also provide you with some basic advice on possible non-combat uses for your powers, as well as putting you on some mailing lists for people interested in part-time or short-term work of the sort that would take heavy equipment or superhuman powers. If you want to hear more about the risks and benefits associated with superheroing, I can explain more?"

"Uh, go ahead and pitch me but I was not operating in a superheroic-analogous capacity at home."

"Oh, if you don't want to, it's fine. No, the main benefit is that you're making the world a better place, but you can also set your own hours as long as you're doing emergency-responder work at least 4 times a year or 12 times each 3-year period, the state pays for insurance, health care, and for pensions in the case of injury but not retirement, and you can set your own schedule. The main risk is that you might get shot, and if you don't have powers that would stop that from happening I would not recommend being a superhero. The pay is also not that great."

"I don't think I have the reaction time to stop bullets. I was going to go to medical school and specialize in things like clots where stopping them in place buys time."

"Then you should not be a superhero," Rachel says firmly, "not unless you have a teammate who can give you very good armor. But that medical school idea is very clever! I'm not sure what your best path for getting there is short-term, though; there might be hospitals that would be willing to take a risk hiring you to use your powers without a degree, but though I can ask around but I wouldn't expect to get anywhere and otherwise you're looking at restarting college." She pauses. "If you want to come in for powers testing, someone might be able to come up for another possible noncombat use for your powers? Or if can get in touch with the Twentieth Century Foundation, and they might be interested in an interview just to know more about your universe? Or I can let you know if anything happens with the tinker who brought you here, if you have his name, and you might be able to sue him for damages if he's caught."

"I could go for some powers testing. And interviewing with Twentieth Century, sure, why not. Doctor Dimensional."

"All right!" She's going to hear some typing. "You're in Chicago?"

"So I'm told. With my brother."

"Right, both of you." She pauses. "I expect Twentieth Century would be interested in talking to both of you, if they're interested in talking to either; I'll call them once I've got your first appointment set up, if you can give me a contact number or when you come in at powers testing? The powers testing appointment should be at -" <type type type> "- tomorrow at 2 PM at -" she gives an address not too far away from the specified motel - "if that works for you. We can get you a pickup if you need one."

"Can you tell me if it's legal to fly around within the city? Or dangerous."

"Wholly legal, and not dangerous at all unless you go above the flashing airplane-alert lights or low enough you might get hit by a car."

"Supervillains don't take random potshots?"

There is a brief pause as Rachel attempts to adjust.

"No. There are not that many supervillains and most of them commit crimes for money. Supervillains in Chicago are usually either in hiding or being arrested by Octavian."

"Okay, cool. We don't have supervillains back home, as a thing, so I didn't know how trigger-happy they are when anybody goes around looking possibly superheroic. I have a fancy outfit, it's," uh, "traditional, for magical girls on my world, comes with the shapeshifting and conjuration thing."

Magical girls. Huh! Rachel does not say. "It's possible, I suppose, but not likely at all."
