Stage a fake mugging and chloroform her when she comes to the rescue

Middle of the night. A dark alley in the bad part of town. A tall, attractive blond taking a short cut home, even tho she really should know better. A sinister figure steps out of the shadows, moonlight glistening off a mean-looking revolver. The woman screams, loud and high pitched, echoing off the walls. The gunman advances, backing his victim up against the wall...

Suddenly there's a red blur and a strong wind fills the alley, and before you can move you find yourself lying on the pavement, bound hand and foot and stripped to your underwear. A bunch of small metallic parts are spread around and it takes you a moment to recognize your gun, disassembled down to its smallest parts.

A man in a bright red costume stops in front of the shocked damsel. "Are you okay, Miss?" the Flash asks. "Do you want me to get the police, or are you..."

The woman shakes her head, confused. "No, that’s... I'm fine, it's..." she looks back and forth between you and her ‘savior.’ “It's actually not..." her shoulders collapse with a sigh. "I'm so sorry, we're actually just, um, roleplaying? It’s... it’s a thing.”

"You're playing…Oh!" Flash suddenly gets it. "You mean you're..." He looks your way; you give him an embarrassed grin and as much of a shrug as you can manage. "Right, ah, I see. I mean, no judgement! Everyone's got their thing, right?" He looks at you again, then back at her. "Right, well, I'll just... yeah." And he disappears in a red blur.

You exchange blinks with your ‘victim,’ but before either of you can say anything, there's another blur and the Flash is back.

"Just maybe next time, y’know, don’t lose yourself in the part, okay?" And then he's gone again.

The two of you left behind stare at each other a moment longer, then she snorts with laughter.

"That wasn't funny!" you insist.

"It's a little funny," your friend says, her voice full of mirth. "Don't look at me like that, the app said she was in the area."

You can't help chuckling yourself. "Shut up and untie me."

She works on your ropes for a minute – that red SOB ties a wicked knot.

"Since when does Flash even work this town?"
