Kid Flash — for all his whispered comments ­— doesn't appear to have trouble keeping up, and a moment later the three of them arrive at a high-tech-looking door, incongruously located in what appears to be a natural cave. Kid Flash steps forward and presses a reinforced doorbell.

The Flash gently lets Topaz down, holding her until she finds her feet again.

"You might want to fix your hair," he advises, gesturing at it. "I can never seem to smooth things out enough for people's hair."

She nods appreciatively, then shakes out her hair, a hand swishing through the frazzled mess. Maybe the regeneration power can help her out a little here, fudging things? But regardless...

Goodness that was a bit of a rush! The contextlessness was a little disorienting but honestly she kind of wants to take that ride again? But yeah, that's a later thought, not a thought for entering the superhero doombase. 

A moment later, the door opens to reveal a man in a bat-themed cowl. The majority of his outfit, however, is a dark grey — the kind of dark grey which, if it were not for the bright yellow symbol right over his center of mass, would make him extremely stealthy in the shadows. Black, true black, isn't grungy enough to blend into the night, and this costume was clearly designed by someone who knew that.

And then decided to add a big yellow logo anyway.

"Welcome," the man intones, in a voice striving for a hard-won compromise between 'gruff' and 'comforting'. "You must be Topaz. This way, please. If you're hungry, I can have some sandwiches sent down."

Immediately, her attention snaps up to take him in. It's the sort of solid sensible armor that she'd expect, and he's clearly buff enough beneath that he just... looks like he's the guy in charge. The emblem looks like a... concession to the style of that the Flashes are using? Probably there's some sort of colorshifting or rotating system to get past that. 

She takes a moment to meet his eyes - eye contact is always hard but getting a sense that he's watching not staring really helps. She relaxes infinitisimally, and nods, trying not to think of it too much as a pure dominance thing, head tilted forty-five degrees down for a solid moment before she picks herself back up and follows. 

"I suppose that makes you Batman, then? I'm not hungry quite yet, but I'd certainly appreciate a glass of water."  

"Indeed," he agrees. "I'll call for one."

He leads their party past a series of displays that look flashy, but which, upon close inspection, are probably not actually particularly valuable. A moment later, they come to a large room containing a dizzying variety of analytical equipment.

In the corner, a dumbwaiter chimes and opens to reveal a glass of water.

"So first I'd like to try and measure your quantum flavor ..."

After a thorough scanning by all manner of devices, Batman runs out of things to try.

"I'm afraid that there is no trace of your origins," he tells her. "Which will make it ... quite difficult to figure out how to send you back."

On the other hand, he has gotten some excellent scans of her shapeshifting power in action — even though it seemed to settle down and start focusing mostly on her organs after a certain point. He'll be updating the cave's monitoring systems with a matching detector this evening, just in case.

"Have you given any thought to what you might like to happen next? I have some experience relocating young metahumans who can't return to their homes, for whatever reason."

...Okay, probably now is the time to get a general research power slotted in. Maybe something that would let her search the internet or 'common knowledge' somehow? Getting a sense of relevant taboos here and the general political enviroment would probably be a good idea. Or maybea social intuition power about general trustworthiness, failing that? Her intuitions about what really matters in this sort of - social combat have never been the strongest. She looks around for a spot to sit, and settles down if she can. 

"It's really hard to say? I've been here for less than an hour, so I don't have a great sense of how... any of this works. You've been nothing but reasonable and respectful, but I don't know really much of anything at all about what this world is really like politically or for a..." 

She bobs her head down and hums lightly. 

"Metahuman, you said?" 

She looks up into the air, eyes unfocusing a little. 

"In an ideal world, this is when I get a general sense that I don't have anything to fear, right now, and I tell you in detail about my powers and tell you about how I feel like I might be able to help - as a 'superhero' or otherwise. I'm just not sure how to get there." 

"Though... it might be a good idea to - explain a bit about where I'm from, first?" 

She cocks her head to the side a little, bouncing the idea around in her head. 

It can do any of those, actually! But not all three at the same time unless she makes space first. Which one(s) does she want?

There's also a verging sense of tiredness — she hasn't hit the limit of how many sparks the gift can make, yet, but it's starting to deplete its reserves of cosmic energy.

Let's do... common knowledge. What does that say about the Justice League and the local government? 

A spark providing common knowledge blooms. Being full of dissynergistic sparks gives her a slight stretching feeling, barely noticeable.

The local government is ... surprisingly similar to the America of her native world, given that metahumans are apparently a thing. In the way of properly functioning democracies, it's not great but it's not terrible, either. It has a bill of rights that is mostly upheld, except for probably-unconstitutional exceptions in the name of border security. The majority of people have representation in government, but Puerto Rico and felons both muddle along without it.

Common knowledge about the Justice League is considerably more interesting. Formed as an alliance of convenience to fight an alien invasion, and headquartered in the Hall of Justice in D.C., it is a team of loosely-aligned top-tier superheros who coordinate to fight global disasters while mostly focusing on their own home areas. While nominally international — and given legitimacy through a U.N. charter — a supermajority of the members are (probably) American.

Some of the members have known identities and origins: Aquaman (who is King of Atlantis), Wonder Woman (who comes from Paradise Island in Greece), Plastic Man (who can't really hide his powers), and Superman (who is an alien). Other members of the league include The Flash, Batman, Black Canary, and Captain Atom.

The League is generally considered trustworthy, although there is perpetual grumbling about their inability to head disasters off before they occur. And the more conspiracy-minded individuals who insist that they're secretly in control of the world, given the group's power and lack of accountability.

"If you feel comfortable with that, I think we would all be interested to hear a bit about your home," Batman agrees.

Okay, yeah, that's about as good a scenario as she could have expected, honestly. 

She drums her fingers against her seat. 

"I come from the Canada of another Earth. It looks a lot like this world, but I'm pretty sure there aren't any metahumans or magic users - there's a few people who have developed a handful of weird party tricks really really far, but not anything even remotely as... 'ungrounded' or impressive as what the Flash can do, and the only evidence we have of alien life existing is a some pictures rovers took of mars that suggest that there was maybe possibly microbial life there, at some point? I don't think the timeline quite lines up, either - it was 2025 when I left, and I think it's a little earlier than that from you, judging from what the cars looked like? Though the technology that they had back in my world is way less advanced then whatever you're using here, so I don't expect anyone from that side will be poking their heads in here." 

She hums a little, her tone getting a little meandering as she slips into storyteller mode. 

"I think my home world is a good bit less - liberal and internationalist then this world? I can't imagine the great powers tolerating something like the Justice League, and there's been a bit of an uptick in right wing populism and nativism that's been a little scary. Still, things... mostly have been chugging along pretty well, and it's pretty prosperous, all things considered. Bililons of people have internet access and smartphones, and absolute poverty is going down all the time, and a lot of the diseases that have been killing people throughout history are finally getting dealt with, at least in richer countries. There's a lot of hate against trans and gay people, if you look in the right places, but it's broadly legal and tentatively accepted, so it's not so bad there, either."

 She smiles a bit wanly. 

He leans back in his (custom, bat-themed) chair. What an interesting set of comparisons for her to draw.

"I think it's sometimes easier to see the bad side of our own situations," he comments after a moment. "One might say that our world is more international because it must be, to counter extraterrestrial threats. But I am always glad to hear about a world where people are overcoming poverty and disease."

Kid Flash, who has been alternating between examining the various scanning machines and losing at ping-pong during the whole scanning process, leans over to whisper to The Flash.

"Is Batman okay? That's, like, a lot more optimistic than I would expect from Mr. 'I am the night'."

The Flash just makes a shushing gesture at him, and then there's a half second of tussling followed by another half second of ping-pong.
