Batman blocked the mallet with a steel reinforced glove and kicked Harley Quinn in the stomach. He was raised to be respectful of women, but that didn't slow him. It would be just one more thing that he would feel vaguely guilty about as he went to sleep. As Harley collapsed, he tossed a capsule that exploded on contact into strands of quick hardening goo at her.
As Harley recovered from the shock of being kicked, she saw her Mistah J shooting at Batman from the balcony. 'Mistah Jay never was a crack shot, especially when he gets excited.' Harley mused as the Joker cackled and fired down at the Dark Knight, who took cover behind one of the hotel's support columns. The hotel had hosted an art show, and was now paying the price for it.
Harley tried to get up, but the goo had already hardened. She strained to get the handle of her mallet under the goo and pry it up of off of the floor. There was some give, with a little work, it would come off. She glanced up at when the sound of firing stopped. 'Oh, that's not good.' Mistah J could handle Bats if he kept his distance, but if Batman got close, Mistah J was Puddin'. Harley stopped struggling with the goo and watched to see what would happen next - yes, there it was. Bats had leaped up the stairs faster than any human should be able to and was almost up to Mistah J.
The Joker pulled out a jagged knife as at the same time he squirted acid at the Batman to slow him down, but Bats just took the acid on this cape and kept going, surprising the Joker with a punch to the gut.
'Ooh, that's got to hurt' Harley commiserated. 'Mistah J is not having a good night.'
Batman blocked the Joker's knife and punched him in the mouth. 'I bet that loosened some teeth, like when Pudding punched me the other day.' Harley reached up and ran a finger across her lips. A shudder went through her body
A normal person would have given up at this point, but the Joker was nowhere close to normal. He never gave up, not when he was fighting Batman. Or when he was punching Harley.
'Black eye!, Black eye! Black.. Yes, that's it!' Harley moaned. Pudding liked to give her a black eye, because the makeup covered it easily. Batmans followed up the hit to the face with one to the side of Joker's chest, "That'll crack a rib' Puddin' NEVER did that. Cracked ribs took a long time to heal, and then Harley would be no use to him.
Batman stood warily as the Joker slumped to the ground 'kick him, kick him, kick him. Oh, poo. I guess that's not Batsy's way'. Batman handcuffed the Joker and and liberally dosed him with the the quick hardening gel before leaping down to check on Harley.
Moments later, there was the wail of sirens, and belatedly, the police arrived, picking up incapacitated henchmen and chaining the joker to a gurney for transport to Arkham.
As Batman walked out to speak with commissioner Gordon, he paused before Harley Quinn.
"You know how this ends. " Batman growled, 'In Arkham.'
Harley swallowed a lump in her throat and nodded. yes, she knew how it ended. With Mistuh J beaten to a puddin' by Bats.
"Why do you follow him?"
"Because I love him."
And she did, especially as he lay battered and bruised from Batmans fists. Another shudder went through Harley at the thought as she snuck a hand between her legs.
