Alison Milligan wasn't just ordinary girl. She was Adam Milligan's younger sister, which meant she was Sam and Dean Winchester's step sister. Ever since Adam and her mom died, she was on her own. She was admitted to the orphanage when she was 13. Things were never same for her. She often cried herself to sleep, but around everyone she acted happy and carefree. Losing her family so fast was one of the most painful things she had ever experienced. She was very attached to her brother and she admired him, but she was also very worried about him sometimes. Her brother mentioned hunting from time to time, but she was never really sure what he was talking about. She knew monsters existed. She was very well aware of the world behind the safety of her home. Sometimes Adam came back all bloody but with that wicked smile on his face. Adam often shrugged it off when she asked him why is he bloody and said it's something he had to do, because dad told him to do it in order to keep their family safe. She never really knew her father. Only thing she knew was that his name was John and that he has two sons who have very dangerous jobs. Sometimes she wondered was it the same Adam was doing.
Adam taught Alison many thins such as how to protect against demons, and taught her how to use a gun and a knife. When she was 12, Adam bought her a handgun and a small knife. Mom didn't like the idea of Alison being pushed towards this kind of job at such young age. She made her go to school and educate. Mom and Adam fought a lot when it came to the topic of Alison being prepared for hunting. But it was just something he had to do in case something happens to him. He taught her so that she can protect herself and her mother. And next year, he was gone. just like that.
She often snuck out of the orphanage in late hours to practice more on her skills. Nobody knew what she was doing. She had to keep it a secret because the less people knew, the better. But sometimes she wished she could tell at least one person. But she knew she was on her own the day her brother died.
It was almost five years since she was admitted to the orphanage. She often hid in her room or in the back where the couples couldn't see her. She didn't want a new family. She wanted to continue her journey without depending on fake parents and siblings. Throughout these five years the group had been decreasing as more couples adopted her friends. She was happy for them. They were really good friends and they deserved to get nice home and lovely parents.
It was 2:30AM and Alison just came back from the deserted backyard where she practiced all this time. She was about to open the door but it was already slightly open. Her heart stopped and she clutched her knife. She quietly opened the door and carefully looked around. Her eyes fixed on a shadow. It turned around, and just as she was about to throw a knife, the shadow disappeared. She took a big sigh and turned on the light. When she turned on the light a horror struck through her. One of her friends, Melanie, was lying on the floor, covered in blood and her neck bitten. Her head was tilted and eyes wide open. She showed no signs of breathing.
"HELP! HELP! ANYBODY! MELANIE'S DEAD!" Alison banged on the doors of the supervisors. They run out of their rooms and started screaming in shock. As soon as the screaming started, everyone woke up. It was horrifying. The groups of gasps and "Oh My Gosh!" filled the room. Alison just stood there and watched. Then she lost it and started uncontrollably sobbing. She couldn't take it, seeing one of her close friends dead on the kitchen floor. The flashbacks of a shadow, the bloody kitchen floor, it was all too much of a massacre for her brain to process. It reminded her of her family. And that's when she fainted into blackness.
She woke up the next morning in her room. The window was tight shut and curtains were not open, but a single strain of light came in. She got up, cleaned herself, put some clothes on and headed downstairs. She did not want to think about the events of last night. Single thought of it and she was close to bursting out in tears. She stopped halfway through the stairs, closed her eyes, and took a big breath. When she opened them, she saw bunch of policemen talking, asking questions and taking notes. Just as she got down one of her supervisors asked: " Are you okay, Alison? You scared me last night, but luckily you just fainted. Please go get something to eat in the living room and there are two FBI agents that want to speak to you." Alison weakly nodded and headed for the living room. As she entered, she saw two very tall guys, dressed in suits. One was taller than the other, and they had formal looks on their faces. Alison gulped and hesitantly headed towards the couch to sit face-to-face with them. Before she sat down, they stood up, took out their badges and the taller one said: "Hi, I'm Agent Culson, and this is my partner, Agent Sanders. We would like to ask you some questions." Alison nodded and stared at them for a second and then looked at their faces. They seemed awfuly familliar. Then she remembered. Those two agents were working on her family's case. She replied: " Hi, I'm Alison. I remember you two, you worked on my family's case." They gave each other a skeptical look and then looked back at her. The shorter one replied: "I'm sorry but I don't think that was us. You got us confused." Alison replied: " No, I remember your faces. My name is Alison Milligan. I was Adam Milligan's sister."
