Because nobody could warn them against it, the Roamers have decided to see how effectively they can bring down an old skyscraper... after making sure nobody is squatting inside.
Simone insisted. She's also being sparing with her inventor skills. That would make this too easy.
And suddenly there is someone sitting on a nearby lamp-post. "Yo, weirdos, what'cha'doin?"
And now he's on Simone's other side. "You couldn't hit me anyway."
Then he appears near the little girl with the portal. "Hail, fellow mover!"
And then he's on the lamp again, chuckling.
He taps the darkness generator on her shoulder. "Careful. You wouldn't like me when I'm angry. You wouldn't know what hit you."
He jumps- He's sitting on a car now. "Okay that was genuinely surprising, good job."
He has acquired a coyboy hat from somewhere. "Now I reckon y'all are considerin' knockin' over one of mah buildings. Do ye have yer demolition permits?"
"Well there's only so many of these things. A lot, admittedly, but a finite amount. So, let's record it all for posterity!"
"Be right back!"
A few seconds later, with a grin and some - flickering - a few big cameras, one of those movie lights on a stand, one of those long-stick microphones, and one of those blackboards that go snap appear. It takes a few seconds. And the stranger is now wearing a fedora and dark sunglasses. "A lonely guy like me is allowed to have hobbies, dahling. I raided this place that was, like, mini-hollywood at some point. I forget exactly when."
"I can be both. Do any of you uncultured rabble know anything about cinematography? Oh, sorry, kidding about the rabble part, you seem kinda organized."
