Chapter 1

Jim Gordon stood in the entrance of Arkham Asylum discussing with the security guards. A stillness fell over the ward, Gordon turned, because he knew who it was. There was only one person who could pull that kind of reaction from both the residents of the asylum and the people who are employed to keep them in their cages.

"Ah, Batman," Jim sighed, "I'm glad you're here. There's been another escape."

"Who is it this time?" Batman asked gruffly, wanting to find whoever it is, and bring them back here and fast.

"Harley Quinn and Poison Ivy."

"What can you tell me about their escape this time?"

Three days later

Batman had scoured every inch of Gotham. But he was never able to find the two criminals. It wasn't until after widening his search a few times, was he able to finally find them.

New York City.

Why they would come here of all places instead of staying in their usual stomping grounds, well he was going to find out. But whatever it was, it couldn't be good.

He followed them to an apartment building. He stood on the opposite building to the one that they were interested in, as the two of them exchanged words. Then Harley went inside the building, and Ivy slipped down a side alley. Figuring out which of the apartments they were after was tricky, but not impossible.

There was a rustling noise behind him, almost turned around, half thinking that it was Ivy trying to sneak up on him when, "Hey Batman. What're you doing here in New York?"

Flash. Of course.

"You know, I don't really see you outside Gotham that much." said Green Lantern.

"You know we just finished a mission and we were all going to go out for drinks, when we saw you, and we figured that we would ask if you wanted to join us." commented Green Arrow.

"What're you doing, anyway?" asked Superman.

"Working." Batman said bluntly.

"Well how about-"

"Shh." Batman said, as he watched using the lenses in his cowl to watch a figure appear in the apartment he had been watching for the past hour. The other supers gathered around to watch. Some equipment to see and hear the goings on of the apartment was pulled out, while Superman just had to tune his hearing and vision to the residence.

Show off.

But, back to the mission.

'I wonder why Ivy is hanging out around us, instead of going inside the apartment with Harley." Batman thought. 'Better get the tranquilizer ready just in case.'

Seven years ago

Dr. Hannah Quinzel was 23 years old, and had just finished her residency at Gotham General. She and some of her fellow newly full fledged doctors, who just like her had just finished their residency, were going to one of their apartments to celebrate. They thought about going to a club, but well Gotham had never been the safest place in the world. And now with these psycho's in costumes. It was safer to stay in after dark.

They had been sitting around Dr. Wallace's Living Room telling stories and jokes of the past few years. Of pranks that they had pulled on each other.

"Okay, I have to ask," Sara said, "How did you do it?"

Hannah looks at her in confusion, "Do what?"

"This!" Sara gestures wildly around her, spilling her drink. "You're 23, the youngest among us. The rest of us are at least 27. Some older. How did you manage to get your M.D. long before any of us?"

Everyone turned toward Hannah, waiting for her response. Everyone has wondered this, and either didn't ask because they didn't want to pry, or because they had meant to, they just forgot to because of work.

"In high school, I took every college course that I could get my hands on." Hannah took a drink from the bottle in her hand. "I also skipped a couple of grades at some point."

"That makes sense." Kevin nodded.

Just as the conversation was about to get started again, all of their phones went off.

Pulling them out, Kevin was the first to comment, "Looks like another break out over at Arkham."

Sara gasped, "Hannah, your sister."

"What about her?" Hannah said worried, as she quickly scanned through the notice that mentioned her sister.

"It would seem that Joker had inside help in escaping. A doctor by the name, Harleen Quinzel. In their escape, the doctor left this message. 'From now on it's me and my Puddin. And it's Harley Quinn. Harleen Quinzel is dead. *Maniacal giggling*'"

The entire apartment was silent as they processed this. The rain pitter pattered against the windows.

"Hannah," Kevin said, laying his hand on top of her arm.

"You know, you aren't your sister." Sara said. She was trying to be comforting. But all it did was remind her of the fact that she and Harleen look exactly alike. And that just might be enough for the Joker to come looking for her.

'What if that psycho wants a set? Twins?' She thought, horrified. Suddenly adrenaline was pumping through her.

"I have to go." She said standing, gathering up her things as fast as she could.

"Wait, Hannah." Jordan said, running after her. "You can't go out there this late. Why don't you stay the night? And you can leave in the morning."

Hannah wanted to. Wanted to think that her presence won't cause her friends to suffer. But she couldn't. She had to leave, now, before they found out she's gone. Before they can stop her. Hannah looked at her friends, and took a moment to memorize their faces. She was going to miss them. And then the moment ended, and she was shaking her head.

"No. I have to leave. Now." And then she was gone.

Present day

Hannah (Now Danni) opened her eyes, and turned to look at the alarm clock next to her head.

12:55 AM

Sighing, she rolled over and put her pillow over head. Tossing and turning for several minutes, Hannah finally gave up. Throwing the sheets off her, she pulled on an overly large shirt to cover the underwear she wore to bed in the summer July heat. Wiping the sweat off her brow, and mentally cursing her landlord for being so cheap, and refusing to install air conditioning, she left the little area that she had set aside for her bedroom and padded across her tiny studio apartment.

Mentally cursing herself for eating grilled cheese sandwiches before bed (It always gives her nightmares).

Stepping into the kitchen and turning on the light, she opened the old refrigerator that must have been in the apartment since the 70's. Peering inside for a midnight snack, but mainly just for something to do, she looked at the dismal contents of her equally dismal fridge.

'Need to go shopping.' she reminded herself.

Finally deciding on something, she pulled out the ingredients for hot chocolate.

Carrying them over to the stove, she began the process, when she sighed.

"The shadows don't suit you." Hannah poured the milk into the saucepan. "Not with that complexion."

"You are absolutely no fun." Harley Quinn stepped out of the shadows, her trademark hammer resting across her shoulders. "And I'll have you know, that I can make anything look good."

"For a weekend," Hannah added the coco powder. "Maybe."

"Ha ha." Harley said, mockingly. "Very funny."

"You came all this way just to make a lame joke?" Hannah mixed in the sugar.

"What I can't come check on my sister?" Harley said, hand on her large chest. Pretending to be hurt.

"Don't pretend that that was your reason." Hannah added the vanilla, and then just stirred the mixture to keep a film from being produced on top of the milk, as she waited for it to become completely mixed.

"It was!" Harley said, her voice gaining an extra nasally quality.

"Okay, then don't pretend that it's your only reason." Hannah sighed, taking the pan off the stove.

"I've always wanted to see the big apple." Harley evaded.

"Harleen (It's Harley!), why are you really here?" Hannah poured the hot cocoa into two large navy blue coffee mugs. She then looked up at her sister, in the way only sisters can.

"Can't I just come see you to talk?" Harley shrugged.

"So talk." Hannah slid one of the mugs over to Harley, and then took a sip from her own mug.

Harley sighed, took a gulp of the hot cocoa and said, "It's Joker."

'Here we go.' Hannah thought, closing her eyes. 'It's always this waste of space with her.'

"What is it this time?" Hannah asked.

"Remember when we last saw each other, and I told you about how he never puts down the toilet seat. Or the milk. Last time we were out, he drank the milk straight out of the carton, and then put it back inside the fridge! Even though I have told him sooooooo many times that it bothers me. That he needs to throw it away. He needs to use a glass."

Hannah remained silent, letting Harleen get all of this off of her chest. Trying to be understanding. Really she did. But it was the same thing every time. The psycho clown would do something that would drive Harleen up the wall, would even do something that breaks their trust. He would hurt her, in every which way that she could think of. And more than likely, ways that she couldn't think of, because he's a psycho. But no matter how much she pleaded with her sister to leave him, to stop being Harley Quinn, a glorified pair of tits in clown make-up, she would refuse to do it. Saying that she couldn't leave her "Puddin'". That he needs her.

Honestly, Hannah has had about enough. If she sees this clown that has hurt her sister this much, she's putting an end to it.

Permanently. Hippocratic oath, be damned.

"Oh, but it gets worse." Harley sobbed. "He's been cheating on me."

"Have you confronted him about it?" Hannah asked. She knew the answer, but she had to ask.

"...No." Harley sighed. "I know. I know. I need to. Otherwise it's just going to fester, and blow up in our faces, and turn violent."

'Like it hasn't already?' Hannah frowned into her mug, just as she finished off the last of her hot cocoa.

Next to her on Hannah's small sofa that they had moved to, Harley finished off her cocoa too.

Placing the mugs on the coffee table, Hannah turned to her sister next to her and said, "I know I've said this before, but Harleen (It's Harley.), please, you need to leave Joker. He's not good for you. You could do so much better than that. He's hurting you."

"No, you're wrong." Harley said, although she was shifting in her seat, uncomfortable. "He would never hurt me. He loves me."

"Really. He doesn't hurt you?" Hannah said. She reaches across and lifts the front of Harley's shirt to show her midriff. "Then what's that?"

And there, clear as day, were a multitude of bruises. Both old and new. And even worse, were the bite marks, where someone had bitten her so hard they had broken the skin. Leaving the skin red and irritated. Clearly infected.

Harley pulled her shirt back down. "How did you know about that? And anyway, it's fine. I'm fine."

"No you're not." Hannah said. Upset on her behalf. "And I knew, because it's always the same with you. You track me down, to whine and complain about your psycho boyfriend, and you ask for my advice. But when I give you my advice, which is, 'LEAVE HIM!' You never listen to me. You never want to admit that he could be as bad as everyone, as I am saying."

"What do you mean?" Harley said.

"Well, there's your outfit for a start." Hannah said.

"What's wrong with my outfit?" Harley said, offended.

"The sister that I knew, would never wear this." Hannah said, while gesturing at Harley's entire outfit.

"It is obvious that you do not dress yourself. You look like a slut. It is obvious that a very, very perverted man dresses you. The Joker does not care about you. To him, you are nothing more than a glorified pair of tits, in clown make-up. He doesn't care. Harleen you're the shrink, if our roles were reversed, wouldn't you be telling me the same thing?"

Harley opened her mouth, but just as quickly closed it. As she was in deep thought.

"Harleen, I really don't want to argue." Hannah sighed. She looked at the mugs and asked, "Do you want some more?"

Harley silently nodded. So Hannah got up, and refilled the mugs with hot cocoa, before carrying it back to Harley.

Harley held the mug between her hands and let the warmth of the cocoa steep into her being. "By the way." Harley said, not looking up from her mug. "Happy birthday."

"Happy birthday, yourself." Hannah gently knocked her shoulder against her sister's, as they both fell into a comfortable silence.

Seconds ticked by, while they sat there, when suddenly Harley lost her grip on the mug in her hands. It fell to the ground and broke on the hardwood floors, but Harley didn't notice. She had fallen over, slumped into the back of the small couch.

Hannah finished her cocoa, set it down on the coffee table. She looked at her sister, unconscious next to her. Then turned to look out the window that looked out to the building next door.

"Well," Hannah said, eyebrows cocked. "Are you going to come take her back to the loony bin, or am I going to have to keep entertaining her when she wakes up?"

Hannah shook her head, and turned away. Picking up her mug, and the largest pieces of Harleen's mug, she went back to the kitchen. Throwing away the broken mug, and going through the motions of washing her mug, she was paying more attention to what was going on behind her.

The soft sigh of the window opening, and the floorboards creaking as large heavy boots walked from the window to the couch. The rustling of clothes, and the moaning of the ancient couch as Harleen was picked up. And then the boots retreated, and the window closed.

Hannah turned around, and she was the only soul inside her tiny sweltering apartment.

Moving to cleaning up the rest of the mug on the floor, she thought about her latest conversation with her sister. Hoping that she finally saw sense, and left him, though she was doubtful. She went to bed, compiling a mental list of things she needed to do in the morning.

(*&%^?)

Two days later

"Master Wayne, may I inquire where you are headed to? I wasn't aware that the League was having a meeting." an aged and old butler asked, as his charge was climbing into the Batwing.

"Harley Quinn's twin." Batman said, "I need to go check on her. I need to make sure that Joker's men haven't come looking for her. It shouldn't take more than a couple hours."

"If you say so, Master Wayne." Alfred bowed his white haired head, turned and left him to it.

(&%&^$?)

As soon as Batman landed, he made his way to the same roof top from two days before. He knew as soon as he laid eyes on the apartment, that something was off. Something was wrong. Using his cape, he glided the distance between the buildings, landing on the fire escape. Making his way to the right window and looking in, his feeling of wrongness increased.

He opened the window, and slid into the quiet apartment. Something was definitely wrong.

The apartment was empty.

Hannah was gone.
