"So how do you do your," she gestures around her ears, "hearing thing?"

"Same you. Just more."

"But is it, like—I mean, you could hear the Picasso from several floors away!"

Nod.

"Lots more. Superpower. Heard them, from the city, going in."

"Wow. A true, real superpower? How'd you get it? Was it a radioactive accident? Did a mutant spider bite you? Were you hit by lightning?"

She chuckles. "No, just... happens, my world. Rare."

"Really? I never heard of that happening to people on Earth."

"Doesn't, as far as I know," her father says, looking at Denice intently.

...oh right, there are other people here. Um.

She shrugs, and puts a little more distance between herself and the Yates. "Dunno. Not, secret, my world, powers. Different one, think."

"Yeah... that makes sense. If there's Earth and the City, and no one from Earth knows about the City, stands to reason there'd be other worlds. What's that programmer saying, zero, one, and infinity are numbers, two doesn't make sense...?"

She blinks at him, startled, but keeps walking without comment; the reaction would be very easy to miss.

"So people from... wherever you are from... just get superpowers like that?"

"Mmhmm. Rare, but, some are famous, not a secret."

"Maybe we'll start getting people from this other place! What's it called?"

"...also Earth."

"Oh. Huh. That's weird."

"But wait, is it like the other Earth? With all those countries, like the United States and, uh... What other places are there?"

"Europe, America, Asia, Africa, Oceania, Antarctica. Lots of countries."

She nods. "Same, yeah."

"Freaky."

"I think it's great! She saved our lives, I bet lots of other superheroes like her can help the City!"

Wobbly enh hand motion. "Villains, too."

"Oh. There are those? I guess there would be. What kinds of powers are there?"

"Lots, um..." she closes her eyes to think; this doesn't slow her down any. After a few seconds, she recites: "Mover, shaker, brute and breaker. Master, tinker, blaster, thinker. Striker, changer, trump and stranger. Different powers... inside those, too. Thinker, me, also precog, also memory power, like that."

"These are types of powers? Ssssoooo... thinkers can, um, do thinking things? Except hearing, so, like, perception?"
