Lin had been 18 when she first met the infamous Joker, the jokester of Jokers, the king over kings. It had been in one of his clubs, one famous for its exotic dancers, violence and flashing lights illuminating several blocks surrounding the building. It was THE club to go to when you want to have a good time but she had never imagined that she would meet the man, much less catch his attention and never lose it.

It had been a regular Saturday evening when she and her friends had entered the famed club. The lights were blinding, their sense of smell overwhelmed by the sudden wave of different smells bombarding them and their hearts beating to the heavy music booming out of the expensive speakers placed in a multitude of places around the spacy room. The trio immediately made their way to the large bar with several bartenders serving the intoxicated guests their alcoholic beverages. Lin was in the front, steadily pushing away people away from her and her group of friends. The dark haired girl, Lin, didn't drink but she went with her friends, even if she wouldn't join them she could still support them and protect them. What happened next would change her life forever, the boring life she had would be but a faint whisper of a memory in the wind.

A man had sat down besides her, a red drink in hand that was probably more drugged up than the regular druggies in the alley besides the infamous place, he had put his hand on her thigh at first. Not wanting to give in to her temper and possibly slip into one of her episodes she resorted to just slap his hand away, hoping that the man would take a hint. He didn't and instead of retracting his hand he pushed it up even further and cupped her. He probably thought that she was just another girl who'd keep quiet and discreetly protest towards his unwanted advances but that had never been her. Instead she turned towards him and delivered a strong and heavy punch straight in his nose. Lin spat on his wailing form and walked away with her nose in the air. The fierceness, the underlying aggression was what had initially caught Joker's attention.

He had seen the group enter his club, of course, he knew all the regulars and all their dirty businesses, all the drama and all the weaknesses. Those three though, those three he had never seen before. The leader of the trio had never graced his club before and it had been a long time since he had seen such a wild beauty. She had pushed her way through the dancers on the crowded dance floor, avoided the sweaty humans and making way for her friends. He had noticed that she didn't order a drink, instead she was surveying the bar and with hawk like yes was making sure that her friends' drink remained untouched. He had been watching the whole thing rather passively until the man sitting next to her, a man way past his prime and an affinity for gambling away the little money he got from pickpocketing the clubbers here, put a hand on her thigh. Now, he had already decided in his mind that she belonged to him and if there was anything that he didn't tolerate it was other's touching his property.

After the display of her obvious dominance and intolerance towards the man he demanded that Frost brought the girl to him intrigued and she did not disappoint whatever expectations he had of her. Lin had walked with a jump in her step and without any traces of fear. If anything she was excited to meet the man. He was going to test her to see if she could survive being by his side and as soon as he pulled out his gun and leaned on it on his cane she brought out her own with practiced movements and not so subtly pointed it at him. The two began hysterically laughing at the same time and that was when he decided that she was going to be his and he hers. That was when both of their lives finally began.

The pair met Harley Quinn or Harleen Quinzel as she was called at the time during a stunt in Arkham Asylum, the two had been brought in by their favorite friend in costume, Batman. The young doctor fell in love with the pair and shortly after breaking them out she joined them in their crazy lives.
