They find themselves in darkness. 

Because of the way Maurice's powers work, he cannot actually create light.

"Um, Hannah?"

Hannah starts glowing. Turns out they're in a strangely empty dumpster. "Hey." 

"...where are we?"

"Las Vegas. Your sister lives a few streets from here."

"What's Las Vegas?"

"Were you raised in the same bunker as Jacob?"

"Huh? What bunker?"

"Wait, where are you from, exactly?"

"Um, my city was called Innata? My country was the République Unifié des Amériques?"

"Huh. You speak good English."

"...everyone there does."

"Sounds Spanish, though."

"My city's official language is Spanish but everyone learns English and French, too."

"Your accent's pretty."

She blushes slightly. "Thank you."

"Anyway, clothes!" She throws some at the other two children. "Also, Maurice, dial down your skin."

He makes his skin look run of the mill caucasian, reluctantly. The universe has suffered a net loss of prettiness. 

She puts her clothes on, too, fidgeting a bit and looking around.

Maurice levitates them out with half a clam shell. 

...And is completely blown away by all the lights.

"PREEEEEEEEETY!"

She blinks at... all of the lights. "Wow. My sister lives here?"

"Well, yeah, in a place with less lights, though. This is where all the casinos are. Vegas is famous for them."

"Oh. Okay. How are we getting there?"

"Do you know what taxis are?"
