A/N/

This is just an idea thats been knocking about in my head for a few days now, I don't know whether or not to continue with it so let me know if you'd like me to.
This is set in the Nolan universe, just after the dark knight, so it isn't based off of Suicide Squads representation of Harley Quinn and the Joker with of course be based off of Heath Ledger's. It will be slightly dark and have some topics that people might find uncomfortable so if that makes you uncomfortable I wouldn't read past this chapter :) Anyway this is the first batman fic I've done so any kind of feedback would help. I hope you enjoy it.

Chapter One

"Inmate #066932, Harleen Quinzel. She was brought in last night by Officer Gordon." Dr Young read the notes out for her newest colleague, a middle aged man with black hair peppered with grey, who's I.D tag read Dr Greene. "She was found by the Gotham river, in a clearly unstable state of mind. Miss Quinzel once worked here, so be careful not to let her get in your head." Looking up from the clipboard, Dr Young regarded the man beside her sceptically. He had only been working at the asylum for a week and in her opinion it was a foolish decision to leave someone who was as inexperienced with the inmates as he was incharge of Harleen's care. Harleen wasn't like some of the patients in Arkham, she knew the place inside out, she was intelligant and she knew the human mind extremely well. "Dr Greene, I must warn you that despite appearances this is a very dangerous woman. Do not under estimate her."

Behind the perspex cell wall Harley sat on her bed, knees curled up tightly into her chest looking anything but threatening. The orange boiler suit that all inmates had to wear hung haphazardly off of her shoulders, revealing bruised and battered skin. Dr Greene had heard the other members of staff talking and knew Quinzel's history, in his twenty-four years working as a psychologist her story had surprised him. Springing a murderous psychopath out of Arkham and then becoming his lover wasn't exactly the norm in most places but he had no doubt with his extensive experience in the field he could help the mentally fragile woman before him.

"For you," Dr Young said, handing the clipboard and file to Dr Greene. "Security can be in there in two seconds flat, and when you start your sessions she will be restrained for your safety. Good luck." With a curt nod Dr Young carried on down the long corridor of cells to continue her morning rounds.

Punching the clearance code he had been given that morning, Dr Greene stepped confidently into Harley's cell dragging a chair in behind him so he had somewhere to sit. Pulling it to a stop beside her bed, he began making the appropriate introductions. "Miss Quinzel, my name is Dr Greene. I am incharge of your care while you're here at Arkham." A small frown creased Dr Greene's forhead when Harley didn't even acknowledge his words, she didn't even turn to look at him. "Miss Quinzel di-"

"I was five and he was six. We rode on horses made of sticks..." Harley sang softly to herself, her eyes remaining fixed on the concrete wall at the back of the cell. "He wore black and I wore white. He would always win the fight." Her fingers curled into the shape of a gun, pointing it at the spot on the wall where she was staring. "Bang, bang. He shot me down. Bang, bang. I hit the ground. Bang, bang. That awful sound." Pausing briefly, she swallowed deeply, her voice cracking as she spoke. "Bang, bang. My baby shot me down."

"Miss Quinzel," Dr Greene continued once the blonde had stopped singing in favour of humming lowly. "I am Dr Greene, I will be your doctor for your time here at Arkham. I wanted to come and introduce myself to you before we start our sessions, I want you to feel comfortable talking to me Miss Quinzel-"

"It's Harley Quinn." Harley corrected.

"Miss Quinn, I want you to feel comfortable in our sessions so that we can improve your situation. Even rehabilitate you and re-enter you into society, it would be such a waste of a life if you remained here for the rest of your life Miss Quinn."

A small smile tugged at the corners of Harley's lips, scoffing she turned to look at the doctor for the first time. "I won't be here for the rest of my life. He'll come and get me." The doctor's eyes shot over to the carved diamond shape around her right eye, the large wound was still some what fresh and raw making most people she came in contact with stare at it. Shifting on the hard bed, Harley grinned at the doctor a mischievious glint in her eyes. "Wanna know how I got this scar?"

The clock on the employee lounge wall read two PM, it wouldn't be long until Dr Greene had his first session with Miss Quinzel and he was still unsure how to approuch the situation. His initial introduction had not gone as smoothly as he had first thought it would; once he had captured her attention she had gone nothing short of feral, of course the security team had been on top of the situation immediately and restrained the small woman before she could do any damage to herself or anyone else. But the outburst had knocked Dr Greene's confidence, he had done everything by the book, done everything in a passive, non-aggressive manner but still he had sparked her fuse.

"I heard about what happened with Miss Quinzel yesterday," Dr Young dropped down into the vacant chair opposite Dr Greene, her fingers lacing on the table. "Don't be too hard on yourself, the woman is a lunatic. I am more than happy to sit in with your session if you'd like me to, I can rearrage some things."

For a moment Dr Greene hesitated, perhaps it would be wise to have a more senior member of the team who knew Miss Quinzel well in the room with him, but being such a new employee he didn't want anyone to think him incompitent. Mind made up he shook his head no. "It's very kind of you to offer Dr Young, but I'm sure I can handle Miss Quinzel alone. If however, in the future I do need some assistance I will not hesitate to come and ask." Standing from the table, Dr Greene made a polite good by and started the long walk through the maze like building to interview room four, where he would be conducting his first session with Miss Quinzel.

Passing through cell block B, Dr Greene descretely took in the various inhabitants making a point of avoiding eye contact and not staring for too long. Cell block B was reserved for the most dangerous inmates, some of which were truely terrifying, one that sprung to mind was Waylon Jones; if rumour was to be believed the half reptilian had bitten off one of the staffs hand, Dr Greene had thanked his lucky stars Jones wasn't one of his patients.
The last cell on the block, before you reached a door that led to the first six interview rooms, was empty. Empty of an inmate, but still completely haunted by the last inhabitants essence. It gave Dr Greene chills everytime he walked past the empty space, the lone playing card still tacked to the wall serving as an every lasting reminder that he had been there.

"Miss Quinn," Announce Dr Greene cheerfully as he stepped into interview room four where Harley was already sat at a nailed down metal table, all four of her limbs restrained by thick leather cuffs. "How are you feeling today?"

"I feel tied down by so many feelings Doc, maybe you could come over here and loosen them?" Harley purred, quirking her unscathed eyebrow.

"You know I can't do that Miss Quinn."

Pouting her full lips, Harley let out a dramatic sigh. She was bored, unlike the doctor opposite her she had been dragged into the sterile room atleast an hour before the session even began and the voice in her head didn't enjoy being caged up like an animal. "You can look at it if you want, I won't bite. Promise." Tilting her face so that more of the diamond shape cut was visable Harley let out a high pitched laugh. "I didn't mean to scare you yesterday Doc, sometimes...the voices get very." She paused momenterily in thought. "Loud."

Dr Greene's eyes widened slightly in shock; in the examination done on her arrival Harley had mentioned nothing of hearing voices, this was small progress. "Dr Young who did you're first mental and physical examination diagnosed you preliminary with a handful of disorders and you have been given medication to help with these conditions. Have you been having any side effects?"

"Uhuh, nothin'."

"Okay Miss Quinn," Quickly Dr Greene scribbled some notes down before continuing. "I want to ask you Miss Quinn who you think you're here?"

A sad look washed over Harley's pretty features, her usual smudged red lipstick and black eyeliner had mostly washed off in the Gotham river and any reminants of it had been scrubbed from her face on her detainment. They had robbed her of her identity, left her naked and bare to stare at for their own amusement. "He'll come and get me." She finally whispered brightly, her blue eyes locking with the doctors. "He will, you see."

"You keep saying 'He' but never stating who you're refering to," Dr Greene already knew the answer before he even asked the question, but with all sessions recorded he needed her to say it. "Who is it Miss Quinn that you're refering to?"

"Well Mister J of course."

The file on Harley was extensive when it came to The Joker, in fact Dr Greene had been taken back by how indepth the clown had gone to ensnare the young Dr Quinzel, in psychological terms it was quite impressive what he had done and with no real background in the field. "The Joker. What makes you think Miss Quinn that he is coming to get you? Did he say something that would make you draw this conclusion?" Just like back in her cell Harley's eyes went glassy, any sign that she was still listening gone. "Do you know where he is Miss Quinn?"

Harley heard him, heard him loud and clear. How stupid did this doctor really think she was? Even is she did know where he was she would never tell anyone, especially not some Arkham white coat who thought they were smarter than they actually were. Mister J would come for her, she didn't need to justify it to anyone, he would come for her because he loved her. He needed her, even if he didn't show it Harley knew that he needed her. It had been her that sprung him from the hell hole she was currently imprisoned in, he couldn't have done it with out her and he would come back for her. Using her chin, Harley nudged the orange jump suit off of her chest and over her left shoulder. A broad grin curved across her face as the doctor cleared his throat at the sight of the jagged 'J' that had been sliced into the skin just below her collar bone. "This is how I know. He doesn't mark just anyone Doc, only special people are lucky enough to have this."

Dr Greene's throat suddenly felt extremely dry, it wasn't the most violent act he had seen in his career but the motive behind it made him feel uncomfortable. The letter was atleast the size of his palm and the violence of which it had been etched into the young womans skin had made the scar raise significantly and it still had an ugly reddish hue to it. This was an act of pure domination and anger, there was nothing passive about it let alone loving. "Was he, The Joker, often physically violent towards you? More than just this one occasion."

"Oh you bet Doc, I have a tendancy to be quite displeasing and Mister J helps me to better myself...for him. For us." Harley said with fondness, memories of her and Mister J playing through her mind like an old movie. "He's too beautiful for this world Doc."

"Miss Quinn as a former psychologist you must be aware of the condition know as Stockholm Syndrome? When a prisoner or person becomes infactu-"

"I know what it is!" Harley snapped interupting Dr Green from finishing his sentence. "Believe what you want Dr Greene but he's coming for me, and he will burn anything that gets in his way."
