A/N: I just watched Suicide Squad, and on the whole, I loved the story and the possibilities that the characters pose. But I feel that certain scenes were missing which would have added to the character development. So I felt compelled to write a few of the missing scenes that happened off screen. The first few chapters are going to be little character introductions, starting off with the fun-loving Harley Quinn. This is my first FanFic, and I don't have a beta, so any help/criticism would be awesome!

The first scene takes place when Harley first meets the Joker at Arkham Asylum, and he asks for a stuffed kitten, which she gives him in the movie. The second scene takes place on "Date Night", right before she's captured by Batman.

All characters belong to DC Comics and David Ayer.

CHAPTER 1 - INTRODUCING HARLEY QUINN

Dr. Quinzel nervously tucked a loose strand of hair behind one ear. She carefully inspected her reflection in the two-way mirror situated across the room. She had insisted on borrowing a white lab coat from one of the doctors, convincing them that this particular patient wouldn't take well to being treated by an intern. Dark shadows stood out under her eyes from the hours she spent last night reading and re-reading the patient's file. She had found herself drowning in the words, unable to escape from the insights into the patient's psyche. It had taken her two months of pleading with the doctors who were mentoring her before she had been handed this case file, and another few weeks before they had granted her an interview with the patient.

The first time she had seen him had been an accident. She had heard about him before: from whispered rumours and newspaper articles. But she had never seen him. Since his incarceration, they'd been keeping his location under wraps, and the man himself in isolation. It had been an accident. One that changed her entire life. She had been escorting a schizophrenic patient to his cell when they had passed in the hallway.

Dr. Quinzel didn't notice the tousled green hair or the manacles wrapped around his wrists and ankles or the dirty straight jacket. She didn't notice the wary way the guards on either side held him, as if afraid to stand too close. What Dr. Quinzel saw was the way he walked down the corridor as though he ruled the asylum, as though the guards at his side were his personal entourage. She saw the gleam in his eyes that bespoke intelligence far greater than anyone she had ever met. She saw something else there, quietly hidden. Something she never expected to see in this man: pain. His soul was in pain. Dr. Quinzel found herself pulled towards him by some unspoken chemistry, and when his eyes met hers, her skin tingled with anticipation. She found herself frozen in place, fear and some other unidentifiable emotion washing over her. The patient passed, and Dr. Quinzel was finally able to catch her breath.

And so, Dr. Quinzel found herself sitting on a thin plastic chair, waiting for the Joker to arrive. She took a quick swig from the coffee cup in front of her and checked her bun in the mirror one last time as the door swung open. Dr. Quinzel kept her eyes locked on the case file in front of her as the patient sat down across the table. For a moment, she was afraid to look up, afraid that she'd see the psychotic killer that she'd read about rather than the intelligent man she'd seen in that chance encounter.

"Dr. Harleen Quinzel." His voice had an odd drawl to it, the edges tinged with barely contained madness. "What do I owe the pleasure?"

Dr. Quinzel's eyes rose, following the straight jacket up past the metal teeth to his brilliant blue eyes. The Joker's head was cocked, his eyes open and intense. She could see the emotions whirling behind them. For the first time in her life, Dr. Quinzel felt like she could see into someone else's soul, without it being hidden by schemes or manipulation. She could see every emotion written in this man's eyes, even if she didn't understand them.

"I…um…" she stuttered. "Mr. J, I'll be your psychiatrist for the next little while. It is my understanding that you weren't getting very far with your past therapists. Perhaps you could tell me why?"

He chuckled, an eerie series of breaths that lasted just a little too long. "For starters, they weren't anywhere near as delicious as you. Just look at that creamy skin of yours…mmmhmm…"

Dr. Quinzel adjusted her glasses, conscious of the heat rising to her cheeks. "I have the notes from your past sessions, but I thought it'd be best if we got to know each other a little first."

The Joker blinked sleepily, boredom seeping onto his face.

"Please, Mr. J. I know it must be hard for you to believe, but I do want to help you. I know you're in pain. Please, just let me help. Could you tell me a story from your past? Something…nice. Something that makes you smile when you think of it?"

She could see the cogs whirring behind his eyes as he thought through her words.

"What makes the Joker smile?" He leaned forward and Dr. Quinzel found herself scooting closer in response.

"Carnage," he whispered, a manic grin spreading across his face. "Blood, misery, chaos, toys."

"Toys?"

"A kitten." He chuckled in that eerie way again that sent shivers down Dr. Quinzel's spine. "A little stuffed kitten."

Dr. Quinzel couldn't help but let a smile tug at the corner of her lips as she imagined a little boy with green hair sitting on the floor of his mother's parlour, playing with a cute stuffed kitten.

"Perhaps you could fetch it for me?" he asked, voice barely above a whisper.

"I know how the foot-in-the-door technique works, Mr. J. I am a psychiatrist, after all." Dr. Quinzel sighed, a small breath leaving her lips. "But I might just be able to get that for you. Something to help keep you smiling through the pain."

MONTHS LATER

Harley Quinn swung the baseball bat and it landed on the man's arm, crushing bone. Her pigtails bounced happily as the man screamed in pain.

"My Puddin' doesn't like being short changed, y'know."

She swung the bat again, smashing the man's fingers as he reached for the gun lying nearby. He moaned and rolled over, blood dripping from his mouth and nose. Harley leaned gracefully over him, bright teeth shining in the moonlight coming in through the warehouse windows. She placed the baseball bat under the man's chin.

"Tonight's date night," she said. "It takes me a while to get ready and I don't have much time left."

Harley added pressure to the bat, pressing down on the man's neck. He muttered something, coughing up blood.

"What? Didn't hear that."

Tears mixed with blood as the man spluttered, his fingers twitching weakly. "It's by the waterfront, on the east side. I swear."

"Now that wasn't so hard." Harley turned, pivoting lithely in her stilettos.

The man let out a ragged, relieved breath. Harley paused, one hand resting on her hip. Then she whipped around, the baseball bat striking against the man's already broken arm. His scream echoed through the warehouse.

"Come on," Harley Quinn giggled. "Just smile through the pain."
