Better destroy the device while he's distracted

You sneak down through the skylight and climb along the rafters to the raised warehouse office. You find the device pretty quickly and smash it to pieces. You look down out of the window and watch as the army of people come around to see The Joker fucking Batgirl dressed as Harley Quinn on a stage. When Batgirl notices that they've been liberated she whips around and punches The Joker out cold. Then the embarrassment kicks in and she quickly looks for an exit. She runs out the side door she came in with the warehouse full of people looking at her red well-spanked ass.

You meet Batgirl back on the roof as she tries to hold the ripped fabric around her ass together.

"What took you so long!?" She yells.

"I couldn't read his mind until he was fully distracted"

"Okay fine, just give me my costume back." She pleads.
