Authors note: This is my very first Supernatural story. Be kind. This story is a reimagining of Season 4 where Sam and Dean have a sister that follows them. She falls for a certain angel. I will try to be as canon as possible but it is AU so it may not be verbatim. I had originally written this with the idea of Jane being in between Sam and Dean in age. I was going to use my own birthday as hers but then I realized that was already Dean's birthday. Ha! And yes this is a Mary Sue fic.

Reworking as of 4/21/12. Not satisfied with it.

Chapter 1

Prologue:

Dorothy Jane Winchester ,or Jane as she insisted on being called by everyone because she hated the name Dorothy, was the twin sister of Sam Winchester and younger sister of Dean Winchester. Being Sam's twin had always been a challenge for her. She was in fact much closer to her older brother than her twin. Jane and Sam didn't share a psychic connection like some twins. Growing up Sam and Jane had bickered constantly each wanting to be their own person. John Winchester had early in their life treated them as equals. They were after all twins. If he'd done for Sammie, he'd done for Janie as well.

John had learned as they reached school age that the twins did not want to be treated as equals. They wanted to be treated as individuals. Therefore, John had stopped treating them like twins and started acting as if Sam were the older brother and Jane the baby of the family.

Not many people actually knew Sam and Jane were twins. They didn't act any more alike than normal siblings. Dean didn't treat them as twins. Sam and Jane really didn't even regard each other as twins. It was almost like they forgot from time to time and then they'd remember as if they'd never heard of it before.

Their roles always fell into Dean the eldest Winchester, Sam the younger brother and Jane the baby of the family. The brothers always protected their little sister.

Jane Winchester was shy like her twin brother but with Dean's temper. She really was a mixture of the two. She didn't really like confrontation and took a back seat to it all when hunting with her brothers. She preferred to be devious rather than guns blazing. Jane liked to stay quiet and subdued. It was something she learned early in life. When you have two brothers who were very strong willed and outgoing it was hard to get in between it. She was a little rough around the edges being raised with only male influences. Her mother had died when she was six months old and her father had never remarried. She read a lot of beauty magazines as a teenager. Make up and nails and periods were something the Winchester men did not deal with.

She had very long blonde hair which hung down the middle of her back. It was just the right amount of wave to keep it from hanging stick straight but not curly enough to cause frizzing. She wasn't overly tall about 5'5". She didn't inherit her twin brother's advantageous height.

Fortunately, Jane hadn't been poisoned by Azazael. Unlike her twin brother, Sam, Jane hadn't been fed demon blood. Therefore, she did not have the unique abilities her brother did. Her only advantage to her brothers was the fact Jane was a woman. Sometimes people were more willing to talk to an innocent looking woman than two brooding men. If a witness or suspect was a man her brothers usually sent Jane in first to 'woo' him.

She had, like Sam, gone to college and been called home by Dean. She'd gone to Stanford with her brother. She hadn't walked out on her family like Sam did. She'd talked to John about going and he'd allowed her but refused Sam. That had been party of the reason Sam had left in such a huff. John hadn't wanted the hunting life for Jane but Sam was a man. It was an entirely different scenario for him.

Jane had been studying to get a business degree at Stanford. She had done very well exceeding in all of her classes. She rarely saw her brother on campus. He was always busy with his own friends. Unlike her brother she had visited home frequently. She missed her family. She'd actually been glad when Dean had called her. She needed to get away from the hum drum of books and libraries and tests for a whilte.

They had been travelling together as a trio for the last three years hunting. The boys were very protective of their baby sister. Sam had been born first and even though he was only half an hour older than Jane he considered himself her older brother. They watched her every move. Dean usually scolded her for dressing to indecently. They frowned on her drinking even though both brothers were heavy drinkers. That fact alone had been the cause of many arguments.

After they had started hunting together, Dean limited her dating. He usually scared off any potential date Jane had. No one was good enough for his little sister. Even though Jane was annoyed by her brothers over protectiveness she was loved them dearly and would gladly put their safety above hers.

Dean had recently been pulled into hell after suffering a very violent death at the paws of hell hounds. Sam and Jane had gone to stay with their friend Bobby. Bobby had been like a second father to the Winchesters. Their own dad was always busy hunting. There had been times in Jane's life when she had secretly wished Bobby was her dad. She never voiced this to her brothers though. Dean was incredibly loyal to their father.

Sam had left Bobby's after a few days unable to cope with the loss of his brother and best friend. He moped around Bobby's for days and when he thought no one was watching him he'd cry. It was after all his fault Dean had gone to Hell in the first place. Sam felt lost without him. He'd always relied on his brother for everything. He loved his little sister but it just wasn't the same. Jane didn't challenge Sam the way Dean did. She didn't argue with him as much. She didn't drink as much. She just wasn't Dean.

He had left promising to look in on his sister from time to time. After all, it was one of the things Dean had made him promise. 'Look after Janie' However, It had been weeks since anyone had heard from him. Sam didn't want to be found. Jane didn't press it. She knew he'd come back when he was ready.

Jane missed her brothers. She knew she could call Sam and he'd come home if she needed him. But Dean? Dean was never coming home. He was dead and his soul was being tortured in Hell. She hadn't been the same since his death. She spent a lot of time crying. Sam had taken the Impala and she found she even missed it. She had taken Dean's cd's from the car before Sam left. She usually played them when she went to sleep. She found herself more often than not curled around her pillow listening to classic rock and weeping. She had a video from her high school graduation which she played every night before going to bed. She didn't want to forget the sound of her brothers voice, his attitude, his mannerisms or his quirks. She knew every second of that video by heart.

Jane had quit hunting in the four months after Dean had passed. She didn't find herself vengeful. Dean had made the deal. They knew he only had a year left. Hunting though just seemed out of the question. Without her brothers she was just a girl. She wasn't part of the feared Winchesters. She was still a Winchester sure but without her brothers she felt like hunting wouldn't be the same so she gave it up. She missed the adventure and excitement but it was nice to return to a simpler life. A normal life.

She continued to help Bobby with research whenever necessary but she took the opportunity to get out of the business. She had found a minimum wage job working as a waitress at the local diner. Everyone had to start somewhere. She had even considered going back to school. She had always wanted to get that degree in hospitality and open up her own hotel chain.

One night in September changed everything.

Jane Winchester had just returned home from working a double shift at the local diner in Sioux Falls, South Dakota. It wasn't by any means a five star restaurant but the tips were decent and the staff was friendly. They served the best peach cobbler. It was homemade fresh every day by the cook who had gotten the recipe from his grandmother.

Bobby had given her a room on the second floor of his home. It was a fairly good size with a walk in closet, a dresser, vanity, bed, end table, the whole works. The furniture had a white oak finish. The walls were white and the carpet was white. Jane had suspected the room may have been a prospective child's room before Bobby's wife had passed. Her bedspread was worn with blue and white flowers, little holes from being moth eaten. She'd been given a plethora of pillows. She'd told Bobby she loved a lot of pillows and he'd rounded up all he had in the house save for the one he used. The curtains hanging in the window were navy blue and musty smelling.

She had turned the room into her own by plastering the walls with pictures of her and her brothers. Most were from when they were younger. The siblings hadn't taken a lot of pictures lately. The most recent picture she had was from Christmas the past year. She'd insisted on taking a family photo at Christmas this year and now she was very glad she had.

There was also worn picture of them at her and Sam's high school graduation. They had ended up graduating from a school they had attended about two months in Sioux Falls when John had sent the kids to live with their Uncle Bobby. The school's mascot had been the gremlin and their colors were purple and gold. In the picture Jane wore a white robe and Sam a purple. Their caps had a gold tassel hanging from it. Dean stood in the middle of the two dressed in his signature leather jacket and tight t-shirt. All three Winchesters were smiling widely. She had cried over that picture many times grieving the loss of her older brother.

She had just sat down on the worn couch and taken off her ugly black work shoes when she heard a knock at the door. Too tired to move she ignored Bobby as he went to open the door. Still inattentive to the visitor she moved into the kitchen to grab herself a snack when she heard fighting, raised voices and scuffling. She ran into the main area to see what the commotion was about and almost fainted.

Bobby had, who appeared to be her older brother Dean, in a headlock. Dean was screaming it was really him and fought to take the knife out of Bobby's hand. Dean being younger and more agile succeeded in his task.

Jane rounded on the sure to be imposter overcome with emotion. This really was an all-time low for the other side.

"How dare you come into this house dressed as my brother? Haven't we suffered enough from your side? Can't you just leave us in peace?"

The Dean look alike stared at her for a moment. He stood with the knife in his hand letting it fall to his side. He just stared at her for a few seconds as his eyes seemed to soften and then he spoke.

"If I wasn't myself would I be able to do this?" he asked taking the knife and slicing his forearm.

The two just stood there momentarily both gazing intently at the blood which ran down the man's arm. Jane's eyes glazed over with unshed tears and she practically leapt into her brothers arms. His arms circled her small frame and he put his hand lovingly on the back of her head as she shook.

"It's really you? How could this be? You were dead! Oh, I don't care how it happened. I'm so glad you're alive." the girl mumbled incoherently into her brother's shoulder her tears soaking his shirt.

They pulled back and Bobby turned to hug Dean. They released after a few moments and Bobby threw water in his face. Jane gave a cheerful teary giggle bringing her hand over her mouth to hide her amusement.

"Can't be too careful," Bobby replied in defense of his actions.

Dean turned around the room seeming to eye every corner.

"Where's Sam?" he asked intently.

The other two looked to the ground. Dean wouldn't like that fact the siblings had parted ways. Dean was always a heckler about sticking together.

"He went out on his own." Bobby finally spoke.

"And you let him?" was Dean's angry reply.

"What was I supposed to do hog tie him in the basement? He's grieving, Dean. He needed time to himself. He calls every few weeks. I tried tracking him but the boy just doesn't want to be found so there's no finding him."

"Watch me," Dean replied picking up the phone making a call.

About a half an hour later the three were on the road headed to Sam who had surprisingly never strayed far from where Dean had been buried. Jane sat in the back seat of Bobby's beat up jolopie staring at her brothers head. She had grilled him on what he remembered and what had happened since he woke. She was just so elated he was alive. She just wanted to hear his voice so she kept asking question after question. He'd finally became annoyed with her questioning and snapped at her. She'd laughed tears in her eyes so happy to hear his mannerisms.

They pulled into the parking lot of a cheesy motel and walked down the hallway to a wooden door with a number inside the heart.

A girl in her underwear answered the door. Jane's first thought was cute underwear followed by ew gross what the hell is my brother doing? The girl didn't seem surprised to see them standing at the door. It was like she'd been waiting on someone. Sam wasn't in sight through the door frame.

"It's about time. Does it really take three people to deliver a pizza?" she said impatiently.

Sam appeared behind her in his pjamas and Dean let out an exaggerated "surprise". Jane applauded his choice of words. Idiot. Sam looked at his sister and then at Bobby and then back at Dean. Suddenly, Sam rushed at the door grabbing Dean and slamming him against the wall a knife appearing in his hand. Bobby and Jane called out to him that they had been through this already and that it really was Dean.

Sam let go and immediately pulled Dean into a hug. She could hear her brothers breathing heavily as they fought not to cry. That wasn't very manly. Jane felt pure joy at seeing her brothers reunited. She went to her brothers and snuggled herself in between the two of them. She felt right. She felt at home. Bobby stood back letting the siblings have their moment tears forming in his own eyes as he watched the three children he considered his own.

"How?" Sam asked after their tender moment was over.

"That's what we were wondering," Dean said as he leaned against the dresser, "How much did it cost you, Sam?"

Sam scoffed, "What do you mean, "how much did it cost me?". I didn't do this."

"Come on, Sam. You didn't make a deal?"

"Dean, look, I tried everything. I tried making deals no demon would have any part of it."

"So the question remains then, who in the hell pulled you from hell, brother?" Jane said still feeling emotional.

Well, the Winchester soon had their answer. Bobby, Jane and Dean were standing in an abandoned warehouse. Bobby was going to summon whatever had pulled Dean from hell. They had already tried to get information with Pamela, a psychic, and it hadn't turned out well. The woman's eyes burnt out of her skull after one glimpse at the creature. Jane was nervous. She didn't like this at all but Dean was set and Bobby was doing anything to please the newly risen boy.

All they had to go on was a name as Bobby started the incantation. He said a few words in Latin. It still amazed Jane that Bobby knew so much about the paranormal but forty years in the business was a long time to pick up a few things. Dean handed his sister a stake just in case whatever the thing was rushed her. She'd need a weapon to protect herself.

After the incantation was finished the three remained tense waiting for the being to appear. It was becoming a long wait. The three shifted positions many times. Jane always stayed close to her brother. She'd been very clingy since he'd walked into Bobby's a few days ago. No one seemed anxious to talk. The three hunters were lost in their thoughts. After waiting for three hours, Jane, Dean and Bobby were beginning to think it hadn't worked when the roof began to flutter and the lights began to explode from their sockets.

Jane gave a yelp of fear and Dean brushed it off as the wind. Unexpectedly, the doors flew open and a man walked through. He was wearing a tan trench coat with a charcoal gray suit underneath. The man walked straight forward his ice blue eyes boring into the three hunters. Jane noted his walk had an air of arrogance as if the man was used to being watched.

Immediately, the men began firing at the stranger. The bullets caused the man's shirt to fray but the man kept moving. A small ghosting of a smirk appeared on his lips. He came to stand in front of Dean. His eyes were only for Dean he didn't even glance at Jane or Bobby.

"Who are you?" Dean shouted as the man rounded on him.

"I'm the one who gripped you tight and raised you from perdition." The man replied with a look of interest on his face his voice deep and raspy.

As the man approached Dean stuck the knife into his heart. It made a sickening meat sound as it entered the man's torso. The man was not fazed by any of it. He glanced down at the knife and removed it letting fall to the ground. Bobby moved to hit him with the iron axe. The man was quick and turned towards Bobby knocking the iron axe from his hand. The man put two fingers to Bobby's forehead and Bobby thudded to the ground. Jane took a step towards Bobby determined to help her old friend. However, when the man started moving towards them she backed up behind Dean. Dean stepped in front of the man protecting his sister.

"We need to talk, alone," the man said reaching for Jane. Dean raised his arms defensively prepared for a fight. Jane moved closer to Dean and peered at the man over his shoulder. She gripped the wooden stake tight in her hand ready to strike. She wasn't sure if it would have any effect.

"Anything you need to say you can say in front of my sister. I'll only tell her later."

The man sighed and turned away from them leafing through the book.

"Your friend is alive," he said absent mindedly turning the pages.

"Who are you?" Dean growled. Jane took another step closer to her brother. She was well and truly frightened.

"Castiel," the man said off handedly.

"Yeah, I got that but what are you?"

The man turned towards the siblings and stood proud.

"I'm an angel of the lord," he said as a flash of light filled the room. Jane could swear she saw the outline of black wings before the lightning flashed again and it was gone.

Dean scoffed, " Yeah right, I'm not buying what you're selling so who the hell are you?"

The man cocked his head in confusion, "I told you."

Dean scoffed again. Jane peered around her brother's shoulder her eyes never leaving the man.

"Right and why would an angel rescue me from hell?" Jane laid her hand on her brothers back. He was very tense but calmed a little at her touch. He moved his head slightly as if he wanted to turn and look at her but didn't want to take his eyes off of the angel.

The man stepped towards Dean a small smirk on his face. Jane's breath caught in her throat.

"Good things do happen, Dean."

"Not in my experience," the eldest Winchester growled. Jane touched his back again. She wanted nothing more than to comfort her brother but wouldn't dare move while the angel was still amongst them.

The angel again cocked his head this time in pity.

"What's the matter? You don't think you deserved to be saved?"

Jane could feel the bile moving up her throat and her eyes immediately leapt to her brother's face. Her eyes sprang hot with unshed tears. She could tell by her brother's face that he did indeed feel that way.

"Why'd you do it?" Dean choked out.

"Because God commanded it. We have work for you," Castiel replied and with that he was gone.

He vanished before their eyes. Jane could swear she heard the fluttering of wings. She stepped away from Dean. The look on his face was heart wrenching. She knew he would close down and chose to not comfort him at the moment. He needed to compose himself. She instead went to Bobby. He was beginning to regain consciousness.

"What the hell happened?" Bobby said rubbing his arm where he had fallen.

"I'm not quite sure," she replied pulling the older man to his feet.

Dean was still standing staring wide eyed at nothing. Suddenly, as if turned by a switch, he seemed to regain himself and turned towards his sister.

"An angel? There are no such things as angels. Demons yes, wendigos yes, ghosts yes, hell, I'd even believe in Santa Clause before I'd believe in an angel." He spat kneeling down to retrieve the knife.

He held it up into the light. It was completely clean. There were no traces of blood anywhere on the knife. Bobby moved in to get a closer look.

"Mind telling me what in the hell happened?"

Dean relayed the story of Castiel and how God had work for him. He told the story with an air of fantasy as he did not yet believe it himself.

"We'd best go and find Sam then." Bobby said gathering his things heading towards the door.

The two Winchesters followed behind him. Just as they reached the door Jane turned one last time to look at the now empty warehouse.

"I'll tell you one thing, though, that angel was damn cute."

End of chapter 1. Ok I hope you guys really liked this story so far. I know it's kinda dry. Introductions usually are. I've been trying to find some good Castiel/Sisterchester fics but I can't really find any. I think I found two and I really didn't like them so I decided to write my own. Review!
