A/N: Look at me, starting yet another fanfiction. I must be insane. Anyway, I've read various fanfictions where Harry is raised by someone besides the Dursleys, and I couldn't help but wonder what it would be like if he was raised by the Winchesters. So, this is my take on it.
Prologue
June 5th, 1983
Mary Winchester had been enjoying her day up until this point. She and John had been spending the day together, while a friend baby-sat Dean and Sam. She loved both of her boys, but it was nice to just have a break once in a while. Sam, being only a month old, always needed a lot of attention. She worried that Dean would get jealous, but he seemed to adore his younger brother. She could only hope that wouldn't change. She wanted her boys to grow up being loyal to each other.
Her good mood was ruined when she saw a certain group of people. They stood out, for several reasons. One was their appearances. The man was huge, and the woman thin. One of the children was already getting fat, and would likely end up as big as his father. The other child she likely wouldn't have noticed at all, since he seemed to be trying to keep out of the way. The only reason she noticed him was because the two adults were yelling at him.
The fact that they were yelling was another reason they stood out. Their British accents only made them stand out more. Mary tried not to be a nosey person, but it really would have been impossible not to hear them, with all the noise they were making. She was somewhat curious as to why they felt the need to yell so loudly at the little boy.
"I TOLD YOU NOT TO DO ANYTHING ABNORMAL, FREAK!" the man was yelling. The little boy looked like he wanted to disappear. There was resignation visible in his emerald eyes, which struck Mary as odd. Children that young shouldn't look so serious. He seemed only a bit younger than Dean, and Dean was always laughing and smiling.
"I'm sorry," the child said quietly. "I didn't do anything. It just happened."
She also wasn't used to a child talking like that. This was just getting more and more odd.
"Don't lie to him, boy!" the woman snapped.
"I'm not lying," the raven-haired child insisted.
What happened next was something Mary couldn't forgive. The woman glared at the boy and slapped him. The force of the slap made his head whip to the side, and already his skin was turning red. Mary couldn't just stand idly by and let this happen, and one look at John told her he felt the same.
"Excuse me, but what makes you think it's acceptable to hurt children?" Mary demanded as she and John approached the couple. She was not one to stand by and let anyone get hurt. Even if she hadn't been raised as a hunter, she would still want to help people.
"None of your business," the man grunted.
"Your wife just slapped a little kid in public. I think that makes it anyone's business," John responded.
"The little freak deserved it," the woman sniffed. The boy in question was looking down at the ground. Up close, Mary could see that his clothes were loose on his small frame.
"What could he possibly have done to deserve that?" Mary asked coldly.
The woman seemed hesitant to talk. She was giving the boy looks of mistrust and disgust. Mary was baffled as to why someone would look at a child like that.
"He's just a no-good freak, like his parents were," the woman finally answered. So he wasn't their child. "We should've never taken him in. I don't want Dudley mixing with that kind of filth."
"If you despise him so much, then why did you take him in?" John demanded.
"We had to. He's the spawn of my dead sister," the woman responded. "Now if you'll excuse us, we have to go."
The little boy finally looked up from the ground, and his bright green eyes locked onto Mary's blue eyes, and he seemed to be pleading with her. Before she realized what she was doing, words came tumbling out of her mouth.
"You're not taking him with you," she told them.
John looked at her in surprise, and so did they. The boy seemed hopeful, yet guarded. It seemed as if he didn't think it was worth it to hope.
"What?" the man said in confusion.
"You head me," Mary answered, sounding more confident. "That child doesn't deserve to be left with you. You're clearly not fit to take care of him."
The man seemed angry at her words, but the woman just gave her a calculating look.
"Fine. You can have him. We certainly never wanted him," the woman told her.
With that said, the couple grabbed their son and hurried off, leaving behind the small, dark-haired boy.
"What did I just do?" Mary wondered out loud. She looked at her husband and sighed. "I'm sorry, I probably shouldn't have done that, especially without talking to you first."
John looked down at the now apprehensive looking boy, and then looked back up at her. "Well, it was the right thing to do. But… what should we do with him?"
"I don't know. I really don't want to just toss him into the adoption or foster care system. He could end up with people as bad as his relatives," Mary said.
"You want to adopt him, don't you?" John asked her. Mary wondered how he could always tell what she was thinking.
"I don't know why, but there's just something about him that makes me want to protect him," Mary admitted. "I know we already have two sons, but would a third be so bad?"
Mary never thought she would rescue a child from his abusive relatives, but then again, she never thought she would settle down with a normal person and have children who wouldn't be raised as hunters like she was.
"Let's take him home, and just see what happens," John suggested. Mary nodded, knowing that was a good idea.
She kneeled onto the ground so she could be closer to eye level with the boy. "What's your name?" she asked in a gentle voice.
"Harry, I think," the child answered softly.
"You think?" she said.
"They call me freak or boy," Harry explained. Mary pushed down her anger at that statement. After all, there was no use being angry now. He was safe.
"Well, Harry, how would you like to come home with us? My name is Mary, and this is my husband, John," she introduced them to the boy.
Harry looked at them with wide green eyes, and then he nodded. "Okay."
Mary smiled at him, and then stood up. She took his tiny hand into hers, and noted the look of shock in his eyes. She wasn't sure if this was the smartest decision, but somehow she couldn't bring herself to regret it. After all, it was the right thing to do.
A/N 2: I would like a beta reader for this, if anyone is interested. Preferably someone who is familiar with both fandoms. Also, should the first chapter take place when Harry is 11, or should it show snippets of his life growing up as a Winchester?
