An hour later I was organizing necklaces in my closet when I heard J's laughter drifting through the doorway. I dropped what I was holding and rushed out to find him. He was in the kitchen with Jonny and Frankie, holding a crystal glass of grape soda when I walked in. Six eyes turned to me and I grinned. "Hi, boys."

"You had quite the day, I hear." J put the glass on the counter and opened his arms. I ran over and jumped into them, throwing my arms around his neck and kissing him.

"I missed you, Puddin'."

"Me too, baby." He set me on my feet and picked up his cup, taking a long swig.

"So what did you do today?"

His eyes glittered. "Oh, I'm gonna show ya."

"Yeah?" I smirked up at him. "When?"

"Soon."

My mind flashed back to his plans for revenge and I giggled. There were quite the number of them. Which one, which one, which one will it be sang in my head.

"You gonna need us tonight, boss?"

"The more, the merrier, Frankie." J looked at the man with a smile. "If any of your crew want in, tell them to carry extra. The forecast calls for a high chance of caped interference."

Jonny frowned, but said nothing. Frankie nodded and left the room. I looked to J and he gestured toward the dining room, "Dinner."

That's when I realized how hungry I was. As we ate together, I told him I wanted Frankie to be my Jonny.

J chuckled, "You like him that much?"

"He saved my ass today. Nearly got my head blown off cuz some piece a shit lied ta me. If it weren't for Frankie tackling me, I wouldn'ta made it outta DeBure's."

He frowned, "Frankie didn't tell me that part."

"I killed them all. I was gonna let 'em go, too."

"No matter. You want Frankie, he's yours."

I grinned. "Thanks, Puddin'."

We finished eating and J told me to wait by the piano while he got ready for our big night. I was surprised to see a young man sitting at the white grand piano, playing a melody I'd never heard before. He smiled and introduced himself as Elliot, but never stopped the flourishing of his fingers.

I was standing at the window, looking out over the twinkling lights of Gotham at night, when J's voice sounded behind me. "Dance with me."

I spun, startled. And then I saw him. My mouth dropped open, heart skipping a beat. I couldn't believe my eyes. He was wearing a full tuxedo with tails, a purple and gold cane in one hand. He has never looked better. What I wouldn't give to rip that offa him right now.

My voice was low and sultry when I murmured, "Hubba, hubba."

He grinned, crossing the room to take my hand. The cane he left propped against one of the windows and then I was in his arms, spinning around the room. It wasn't a waltz but something uniquely our own. I felt like I was dancing among the stars, clouds beneath our feet. The way he looked at me while we moved about the floor … I never seen love like that before. I know I was staring in his eyes with devotion, my heart so overflowing with love for him that I thought it would explode.

We danced for a while, enthralled with each other. He finished by dipping me upside down and the music drew to a sweet finale. As he pulled me upright, he brushed a white gloved thumb across my cheek. "It's your Gotham debut, honey."

I grinned. "Let's have some fun."

He pulled out his phone and sent out a mass text. Jonny was waiting for us down in the garage. He held open the rear door of a purple Lamborghini and I climbed in. J walked around to the passenger side and got in the front. I noticed something as Jonny slid into his seat.

"Hey, my mallet!" I picked it up off the floor. "Who cleaned it?"

"I think it was Iggy." Jonny started the car and drove to the secret entrance. I don't know that one…

The wall popped inward and slid to the side, and we were in the underground tunnel. I bounced my head to the beat of the music playing through the speakers and did that sort of shimmy-wiggle car dance. When the chorus started I threw my arms in the air and belted out the lyrics at the top of my lungs.

J jumped and growled, "Har-ley!"

He turned in his seat, searing me with irritated stormy eyes. My lips pinched closed and I dropped my hands into my lap. "Sorry, Puddin'."

We drove for a short while before surfacing. "This ain't the alley. … How many fucking secret entrances you got stashed around Gotham?"

J snickered. "You want a map, baby?"

I huffed. "Yeah, I think I do."

He just laughed. Jonny drove a little while longer before finally pulling into Gotham Water Treatment. I knew instantly what we were doing there and giggled, slowly growing to full blown laughter. The car stopped in front of a fleet of white work vans and we got out. I stepped over to J, hooking my arm around his.

"Is it time for payback, Puddin'?"

"You know it, Pumpkin."

Jonny led us inside, where dozens of men lined the hallways. All the electronic door locks were green, having been beeped through, one man stationed at each door to keep it open. It was like following a trail of breadcrumbs to the room where jackhammers ate away at the floor. When they were through, other men stepped forward and shoveled away debris from the massive pipeline underneath. Then others moved in with blowtorches and cut away a large section off the top, exposing the lifeline of the city. This was the last stop before the water flowed through smaller pipes and reached the taps of every Gotham citizen.

Through the door came a half dozen guys with dollies carting bright yellow barrels. They approached the hole in the floor and arranged the barrels around it. We crossed to the group around the hole, J spinning his cane as he walked, and I saw that the barrels were stamped Ace Chemicals. I looked at Jonny and he confirmed my suspicions. "We were already there that night, getting these. That's why I got to you guys so quickly."

J popped off the basketball sized rubber seal and tossed it aside. The stench that effused from the yellow-green liquid inside made my eyes water.

"What is that stuff?"

"Poison." J said simply and he knocked over the barrel, its contents gurgling into the water supply. He laughed maniacally and delicious shivers ran down my spine.

"I know that. I just meant what specifically."

"Who gives a shit?" Good point.

Something whistled as it flew past and lodged into the man standing next to J. He dropped to the ground, a batarang sticking out of his chest. J tossed his head back and laughed uproariously. "We've got a bat in the belfry!"

I spun, lifting my eyes in search of him. Gunfire rang out all around me and J was grabbing my hand, yanking me to the side of the room. The muzzles of the firing guns moved like a flock of birds as the men tracked their foes. The "heroes" dropped in the center of the group, two dark flashes that disappeared amidst the bodies. A few of J's men continued to shoot as they'd dropped, catching their own in the crossfire.

"Idiots." I muttered. The sounds of punches landed and the grunts of fighting men converged. I watched the fray, absorbed, trying to catch a glimpse of the men I despised. Then a crashing sounded and my head snapped to the barrels, where J had just pushed over another one. I rushed over to him and gripped the seal on the third, yanking it off. And then I pushed, throwing my body weight against the barrel. These fuckers are a lot heavier than they look.

I turned and put my back against it, planting my feet firmly and using my legs to press backwards. I heard the clang of another barrel tipping over and strained harder. Finally, it started to tip but I couldn't catch myself in time. It fell and I tumbled over it, shrieking. Someone grabbed onto my elbow, their forearm pressed to mine, and I hung over the rushing water for a half a second before I was pulled back. Jonny placed his hand on my shoulder, making sure I was steady on my feet before letting go.

"You ok?"

"Robin!" Yelled a deep voice from the middle of the fighting men.

"On it!" Yelled another voice and a man in a dark red and black suit vaulted over the heads of our boys in our direction, cape flying behind him

"Help J!" I ordered Jonny and picked up my mallet, swinging back like it was a baseball bat as I rushed forward.

Robin landed a few feet in front of me and I swung with all my might, smashing it into his shoulder. He was taller than I thought he was gonna be. I was aiming for his head. He stumbled sideways and fell to the floor but flipped back onto his feet in seconds. The eyes in the black mask stared quizzically as he spun the silver staff in his hands in circles around his body. "Who're you?"

I giggled and raised the mallet over my head. I aimed for his head again, but the staff knocked it and my momentum aside and I stumbled. He rushed past and grabbed one of the barrels, pulling on the rim until he had it standing. I growled and ran at him, swinging my weapon through dead air when he ducked. He spun to face me, whipping the staff like a bat and I backflipped. It jabbed at my chest when I righted but I bent backwards out of the way. Back and forth we went, trading near blows. Then I caught one in the stomach and grunted, falling to the ground. Robin grabbed onto another barrel, and yanked it upright.

"Harley!" J's voice, calling from the side of the room.

I snarled as I looked up at the Boy Wonder and jumped to my feet. I ran at him, launching myself onto his back and yanking the handle of my mallet against his throat. He reared back, dropping the staff and grabbing at me but I hung from the mallet, my toes just barely brushing the ground. I pulled as hard as I could and heard a satisfying gurgle.

He gripped my wrists and lifted me off of him, throwing me over his head. I hit the wall upside down and slid down to land on my head. I laughed as I got to my feet, spinning the mallet in a circle in front of me. "Let's go, birdie."

I rushed forward at him, caught completely off my feet by someone grabbing around my midsection and hauling ass sideways. I shrieked in rage and elbowed Frankie in the face before I realized it was him. "What are you doin'?!"

He didn't answer and ran out of the room into a different hallway than the one through which we'd entered. Frankie powered through the hallways until we were outside in a dark alleyway. J was leaning against the building but Jonny was nowhere to be seen. I was finally placed on my feet and I smacked him.

"What'd ya do that for? I was havin' fun."

"Batman was nearly finished with those guys. You really wanna go two on one with the Bat and his sidekick?"

I growled but turned away, looking at J. "They're gonna stop the poison."

"I made my point." He grinned, sweeping a hand at the lights that glimmered, a million lives in a million windows. "The loss of life will be catastrophic."

I sneered. "Not enough."

J laughed. "My little monster."

"After everything they did to you in the name of 'saving the city,' you're damn right." I snarled.

"Where's Jonny?" Frankie moved the gun hanging on his back to his front, fingering the trigger as he looked around the alley.

"Getting the car."

Kill them all, the worthless sacks of flesh in this city.

If the Bat can lose control, so can we hahaha!

He fights to protect these people; the perfect payback is slaughtering every last one.

Frankie started down the alley and I moved to follow, then stopped and turned around to face J. "This is what you been workin' on since we left Arkham?"

"I've been planning this for months." He grinned.

"Ya shoulda gotten more barrels."

His smile widened as he approached me, placing one palm on my cheek. "Your unquenchable thirst for death and destruction only makes me love you more."

I threw my arms around his neck, dropping the mallet in the process, and pressed my lips to his passionately. It was the first time he'd said he loved me and I was filled with delight at his confession. He turned, walking me backward until I was pinned against the wall and slid his hand down from my face to curl around my throat. I moaned at his forceful touch, arousal flooding between my lower lips.

A distinct flapping sounded then and J pulled away, whirling. A dark figure landed a short distance away, slowly rising to his feet, and my eyes laid on the Dark Knight for the first time. I scowled, moving away from the wall to pick up my weapon.

"You won't get away with this, Joker."

He laughed, "I already have, Batman. There's no antidote."

"Not yet."

I cackled. "You think you can make one in time? … One little sip and they're dead."

The Bat's eyes turned to me, recognition flashing in them. "It can't be … Dr. Quinzel?"

I laughed harder, the mallet spinning in my hands. "Sorry, Bats. She's dead." My grin was wicked as I arched my brows and lifted my hands by my shoulders. "I'm Harley Quinn."

He looked back at J with fury in his eyes. "What did you do?"

Joker doubled over in laughter and I couldn't help but giggle. "My Puddin' gave me an opportunity. And I just … jumped."

Batman scowled and rushed at J. I swung my mallet, barely catching him below one pointed ear on his cowl, and he stumbled against the wall. He whirled and ran at me, grabbing my upper arms and slamming me against the opposite wall. The pain of it washed through me, eliciting another giggle.

"Ooo, you know I love it rough, Batsy."

He frowned, shaking me a little. "I can help you, Doctor."

"Like you helped him?" I snarled. "Like you damaged him?!"

I smacked the mallet into his side and he released one arm to grab it and toss it down the alley. The arm he'd released whipped upward and I punched him square across the jaw. I heard a gun cock and he turned, revealing J behind him with one arm outstretched, the muzzle of his Colt pointed at the "hero's" head.

"Let. Her. Go."

Bullets rang from down the alley, Frankie's voice yelling incoherently. I ripped my other arm from the Bat's grip and rushed to pick up my mallet. Headlights swung behind Frankie, his shadow stretching toward us. A second gun started firing, Jonny leaning out the window as he drove past Frankie in our direction.

Batman pulled some kind of gun from his belt, aiming nearly straight up. A grapple shot from the end, hooking onto something, and he flew upwards. I growled, my eyes following him, wishing I had my own gun. Jonny stopped a few yards away, the headlights illuminating us. I heard Frankie's heavy footsteps running down the alley.

"Time to go, honey." J gripped my wrist, pulling me behind him as he made for the car. I opened the rear door as he got in the front, leaving it open for Frankie. He got in a few seconds later.

Tires squealed as Jonny slammed on the gas, the rear wheels drifting slightly before the vehicle shot forward. He careened down the alley, spinning the wheel at the end to take the corner hard. We sped around the city, Frankie continuously turning to look behind us.

"What're you looking for?"

"The Batmobile." He answered.

"The Batmobile, the Jokermobile." I leaned forward, pouting at J, "When do I get a Quinnmobile?"

He chuckled. "You can have any of my cars."

"But I want my own."

He turned, eyeing me with a grin. "Then you shall have one."

A huge smile overtook my features and bounced excitedly in my seat. "Yay!"

The Bat and Bird never showed on our tail, but Jonny still took a secret entrance back to the high rise. When we got back to the penthouse, J turned the TV to the local news station. They were reporting on my crime spree, a picture of me blowing a kiss in the upper corner of the screen. I squealed excitedly and jumped up and down on the couch.

"I never been on TV before!"

J frowned slightly at my antics, "Harley, sit down."

I jumped one last time, landing on my ass and wiggling until I was comfortable.

"Just who is Harley Quinn, and what does her arrival mean for Gotham?" said the female news anchor.

"Police are questioning if she has any connection to the established criminals in this city, or if she is a newcomer in her own right. If you have any information on this woman or her string of robberies today, contact the Gotham PD by calling the number on the bottom of your screen." The male anchor picked up his stack of papers and tapped them into a neat pile.

"Or just wait a few hours and see who she's with." J cracked.

We watched the news until a Breaking Report graphic flashed on the screen. The normally serious eyes of the reporters turned grave and solemn. "Do not drink the water! We have just been informed that there is poison in the water supply. Emergency Departments across the city are flooding with the sick. Thus far, no antidote has been discovered, and the total dead have already reached over 200."

"Commissioner Gordon has informed us that Batman has taken a sample of the poisoned water to Gotham S.T.A.R. Labs in the hopes that an antidote can be developed. We will update you as new information comes to light."

I bounced in my seat, giggling madly. J pulled a joint from his pocket and lit it with his zippo, taking a long drag before holding it my direction. I plucked it from his fingers and sucked on the end, inhaling the smoke deeply into my lungs. We smoked for a long while, watching the death toll rise as minutes passed. Eventually we went to bed, but not before the number of fatalities broke one thousand.
