Batgirl uses Reverse Psychology

Seeing one way out of this, Batgirl leaps into action and...

…grabs Harley Quinn in a Hammerlock! She stays behind her as she tries to act out her plan.

"You can fight me any day," she says, "Hell, I'll probably fight half of you by the end of this week. But, hear me out, how many chances do you get at this bitch?"
"Take her out, you stupid gits! Harley says so!"
"See- listen to that. Why is she bossing you around? She's nothing more than Joker's girl, right?"

She hopes that playing to the group's innate Sexism will help them get on her side.

A murmuring goes through the group. Some of them are considering her offer.

"Get her! How dumb are you assholes?!?"
"More of the same," Batgirl says, hooking one of Harley's legs with her own to keep control, "She thinks that she's better than you, but..."

With her free hand, she pulls back Harley's hood, exposing her blond hair.

"She's just a woman. She's not better than you."
"Betrayer," Harley whispers angrily.
"No, I'm just smarter than you....So, who wants to take their aggression out on this bitch for, let's be honest, the one time they'll get the chance?"

A louder murmuring. They all seem to be in agreement.

"Alright," Batgirl whispers, "I'll let you go."

She lets go of the hold and pushes Harley forward. With her leg hooked, the Villain trips and falls to the ground.

Batgirl deftly backflips away to safety and watches as the group moves in towards the dazed Villain.
