"Yes," says Mark. "I don't know what to look for, but Miles and I can guard you on your way and if we are in a location unfamiliar to you I am sure Miles can navigate."
"I'm not sure where we are but if we hit civilization I can figure it out, I just never did get my wilderness survival girl scout badge."
"I walked here from the school. Finding civilization won't be a problem. Ready to go, then?"
"I think I can walk, and if you didn't find anything hostile on the way here it probably doesn't matter if I can also do a few dozen backflips."
"We have a stunner, a nerve disruptor, and Mark. I think we're set for any combat situation not involving literal armies."
He reopens the door and leads the way out.
"I don't know what that is but it looks plausibly relevant," says Miles, pointing out a payphone.
"Yep, that's a phone." She pats herself down for her wallet: she at least has not been robbed. She puts quarters in the pay phone. She talks to her dad. "Charlie's going to come pick me up. Thank you both."
"If you'd like my assistance in finding and assassinating the person who put us in that house, you shall have it," says Mark.
"I'm staying with a friend right now but he doesn't want Bella knowing where he lives because she scares him," says Miles. "And none of us has a phone."
"I could just tell you where I live but the place is not designed to be a pleasant vampire hangout."
And presently a cop car rolls up and Bella converses with the occupant and waves to the vampire twins and hops in the passenger seat.
And the vampire twins traipse off to presumably do vampire twin things perhaps involving loitering.
