A/N: I don't own Supernatural, just the sligth plot differences and my OC. Warning this is a Sisterfic, but unlike the ones I usually read that have the sister being Sam's twin, well its not like that. *smile* Enjoy. Please read and review.

January 24, 1979

Lawrence, Kansas

Hospital

A tall man stood outside hospital room, waiting for the news. His attention was drawn to the door as a shorter man in a white coat came out with a clipboard in hand and a dark look on his face. "Mr. Winchester? I'm Dr. Karl Johnson. You don't need to worry; your wife and son are doing fine." The doctor offered the other a grim smile as John looked up in worry, "What about the other one?" He asked, his voice brimming with fear. Dr. Johnson shook his head, "I'm sorry to tell you that your daughter did not survive." John slumped in his chair and grabbed his head. "I'm sorry for your loss Mr. Winchester, but you may see your wife now." With that the doctor turned around and left the area, and John stood up to walk into his wife's room. "John..." He winced at his wife, Mary's choked sobs. His quickly hugged her and kissed her head. "It's going to be alright Mary." He said into her hair, forcing any tears that he may have had back down, he needed to be strong in front of his wife.

Their stressed silence was broken as a small cry filled the air from Mary's arms and they both looked down on their newborn son. Mary cooed at the baby and managed a tight smile as the baby giggled a little bit. Then she looked back up at her husband and stated, "We have to be strong for Dean." John nodded and placed one of his big hands on the small baby and smiled lightly when Dean put a hand on his. "That we do, Mary that we do." A nurse rushed in as the couple made their promise, "Mr. Winchester? Has the doctor visited you yet?" When he nodded the nurse's expression grew scared, "What was his name?" John blinked as fear grew in his gut, "Dr. Karl Johnson." The nurse cursed, "Mr. Winchester, there has never been a Karl Johnson working here. I'm sorry but I have to go find my boss." With that the nurse ran out of the room and down the hallway, leaving a pair of very shocked parents. "So, my baby girl's still alive?" Mary whispered as John ran to the window and looked out, spotting a retreating form of the fake doctor.

Outside Hospital

The man that had introduced himself as 'Dr. Johnson' walked briskly through the parking lot. He turned his head slightly to look back and his eyes met those of John Winchester. He smirked and showed the watching man the bundle in his arms. His smirk turned into a wide grin as John's eyes widened and he mouthed 'no'. Then the man turned back and waved behind him as he got into a car and quickly drove off.

10 years later, January 24, 1989

Just Outside of Fort Douglas, Wisconsin

John Winchester cursed as he pushed through the underbrush, his leather trench coat catching on some of the sharper branches. He needed to get back to the hotel where he left his sons quickly. He had discovered that the creature he was tracking was a shtriga, a vampire-like witch that fed on the life source of young children. He cursed again as he crashed out of the woods, quickly heading for the black 1967 Chevrolet Impala parked across the road. He was in the car and already pulling out when he noticed the note on the seat next to him. His breath caught as he read the scrawled sentence.

Hello John, how are you doing since I killed your wife? And what's more, I also took your daughter as well. Poor, poor Winchester family. Do your boys even know they have a sister? Does Dean know that he has a twin? You'd better tell them, if you want to save your little girl, who just happens to be in a life-threatening situation at the moment. After the first few months of having to take care of her I gave her to an orphanage. But unfortunately, you Winchesters seem to draw danger to you. By the way, you should probably get to your sons. And then you should hurry to the hospital and get your daughter. You should be happy to know that I gave her the name you and your wife wanted her to have. See you later.

John's eye widened after he finished the note. Then his eyes narrowed and crumpled the note, peeling away from the side of the road and tearing down the highway, towards the motel he left his sons in. His mood was darkening as he drove as he tried to figure out if it was a trap or if his daughter really was in a hospital. Furthermore, if she really was, how in God's name did he explain it to his sons. His phone rang and he quickly answered it, "What?" He demanded. A feminine sigh was heard on the other end, "Are you Mr. John Winchester?" She asked, a shuffling of papers heard in the back ground. "Yes. Who is this, and how did you get this number." He said, cautiously. "It's in your daughters records. Along with her blood-type and the name of her mother. This is Douglas Hospital, and I'm calling to inform you that your daughter, Liam Winchester is in our care for a broken wrist. But for some reason, she also is a very heavy sleeper. She hasn't woken up since we brought her in. I was wondering if you could come and get her any time soon." The phone almost dropped from his hand because of it shaking so much. "Yes, give me about thirty minutes to get there." The woman on the other end voiced her confirmation and John shut the phone.

The muscles in his shoulders were tense as he picked up speed and practically flew down the highway towards the hotel. His thoughts were a jumbled mess as he tried to make sense of what just happened. He received a note telling him that his daughter was in fact not dead and then received a phone call telling him that she was in a hospital less than an hour away from the hunt he had taken. He slammed his fist into the wheel and cursed.

He had only left the room for a few minutes, and he was cursing his own stupidity. A young boy, Dean Winchester rushed to the door of their room. As he pulled it open he saw his dad gank the monster that was above his younger brother, Sam Winchester. "Sammy!" He called, rushing over to the pale figure. His dad just stood above them unmoving for a second and then suddenly in action. Sam and Dean watched as their father packed up their things in a stunned silence. "Let's go." He said gruffly and they were shocked into movement as they grabbed bags and helped their father pack up the Impala.

"Where are we going next Dad?" Sam asked, his shaggy hair sticking up a bit. John looked at them both and sighed. "Boys, I'm about to tell you something, and I should have told you sooner." Both boys perked up at that and listened intensely. "Dean, Sam you have a sister. Your mom and I decided not to tell you until you were older, but then she died. We both accepted the fact that we probably were never going to see our baby girl again. But I just got a call from a local hospital that she's somehow showed up in. To answer your question Sammy, we're going to pick her up. After confirming her story." Both brothers looked at their dad in shock. "Wait, we have a sister?" Dean asked, brain flipping. John nodded and picked up speed a bit.

Less than fifteen minutes later the black Impala pulled into the hospital parking lot and three figures got out and quickly made their way up to the reception desk. The fair-haired lady sitting there looked up and smiled at the man and two children, a pin on her shirt proclaiming Jenny, "How may I help you?" John identified the woman as the one he had spoken to on the phone and stepped forward, "I believe you called me earlier to let me know that my daughter was in the hospital." Jenny's eyes widened, "You're John Winchester?" When he nodded she quickly stood up and motioned for them to follow. "Your daughter has been quite a handful, even with a broken wrist. She mostly glares at people, unless they are helping her. And she won't answer any of our questions." The nurse rambled until they came to a stop in front of a door down the hall. "And here we are, the boys can go in but I need you to come with me and fill out a few forms, and of course take the mandatory blood test." John nodded and motioned for the boys to go into the room as he followed the woman down the hall.

Both boys shared a look and opened the door. The room they walked into was a typical hospital room, white and smelled like bleach. Dean looked towards the bed as Sam continued to survey the room. A girl that looked about his age sat in a chair next to the made bed, an old-looking book in her hand and a sucker stick hanging out of her mouth. Both boys froze as the door shut and drew the girl's attention. Dark hazel eyes looked up at them and then narrowed, "Who are you?" She asked, watching them intently. Sam gulped and stepped forward, a hand held out, "I'm, uh, Sam Winchester and this is my older brother, Dean. And um, we're-""We're your brothers." Dean said flatly. The girl raised an eyebrow and looked at both of them with new eyes. Eyes that were the same color of Dean's, Sam realized, looking between the two. He slowly realized that the two had more in common than just eye color.

The girl sighed and stood up, finally taking Sam's outstretched hand, "I'm Liam. And I guess my last name would be Winchester as well if you're right about me being your sister." The newly named Liam said, standing unknowingly next to Dean to shake Sammy's hand. Sam's eyes widened, give or take an inch they were both the same height. That and now that they stood next to each other it hit him. His eyes gleaming he questioned Liam, "How old are you?" She blinked, "Ten. Why?" Sam ignored her question and continued, "When were you born?" She thought for a second, "January 24. And again I ask why?" Dean's eyes widened as he finally figured out where his little brother was going. His eyes turned on his newly found sister and looked her over. She was his height, maybe a little shorter, had shoulder length dark blonde hair and had hazel eyes. Place that although her frame was thinner, they had basically the same body shape, "You're my twin!" He exclaimed, gaining both of his sibling's attention.

Liam's eyes widened as she also took in the similarities. She was about to say something when the door opened and the nurse and a taller man walked in. He gave off an intimidating atmosphere and had dark hair. Jenny smiled at Liam and walked over to talk to her. "Liam, sweetie, this here is your daddy, John and he's here to take you home." Liam's eyebrow twitched as she narrowed her eyes into a glare. "I'm not a five year old. I don't need to be babied, I'm ten, and I'm not your 'sweetie'." She said, voice calm but tight. Jenny stepped back in shock, "Whatever. Mr. Winchester, " And turned and left the room with Liam glaring darkly after her. After she was gone, Liam turned to John, "So you're my dad?" When he nodded a grin formed on Liam's face, a spitting image of Dean's. He sighed, already seeing the trouble both would probably get into. He was broken from his thoughts as two arms hugged him around the middle.

When he looked down he saw a thin line of tears going down Liam's face. "I always knew I had someone out there." He heard her whisper. He put his hand on her head and frowned; both brothers watched curiously and were shocked when their dad waved them over, turning the father-daughter hug into a family hug. With that the ice was broken and Dean grinned at his twin, "Boy do we have a lot to tell you!" Liam grinned back and soon Sam joined in, John watching his kids with a light smile, 'Mary, if you could see our kids now.' He looked up and then back at the siblings, "Ok, guys lets go." They grinned at each other again and nodded.

Hope you enjoyed. Please review.
