A/N: Hi :) I've been so excited for this chapter! I'm going to warn you now that this is a little shorter than the rest due to the amount of content in it. I feel as if there's a lot to take in and I didn't want to over do it. Big thank you to everyone reading, to those of you who are following and anyone who added this to their favorites. I hope you enjoy it!

Three days passed and they weren't making any progress with their research. They had found a ritual that unleashed every demon from hell, a ritual that banished all angels to hell, there was even a ritual to drop all of mankind into hell, which was confusing to all of them. Dean had decided it would be best to wait it out until Castiel returned, hopefully he would have something that would at least lead them in the right direction.

Late into the night, after they had given up their search, Ana sat at the large table in the library with her eyes focused on the cloth and small gun part in her hands. The fact that they hadn't been able to find anything on the ritual had her stressed and she wasn't able to go to sleep when she finally went to bed. She needed to take her mind off of it and out of the few options that she had in the bunker she had settled on cleaning the gun she had used the night at the bar. As she suspected it wasn't that dirty, Dean cleaned the guns so often that she would have been surprised if it actually was dirty. She cleaned it none of the less, part of her remembering the words from a memory, "You shoot it, you clean it."

The gun sat on the table, still in pieces as she sat back in her chair and yawning. Reaching for her phone that sat on the edge of the table, she hit the home button to check the time. It was almost two in the morning and she was just barely feeling exhaustion settling in, hopefully she could sleep in tomorrow, She sat back up and began to put in pieces back into top part of the pistol, just as she was just about to position the recoil spring assembly into place she caught movement out of her peripheral vision.

"What do you think you're doing?" Dean's voice was deep and gravely, paired with the look on his face and clothes he was wearing it was clear that he had been sleeping. She had been staying there for almost a week and she had never seen him wearing anything other than jeans, which made seeing him in sweats and barefoot that much weirder.

Ana looked back down at the gun, putting the spring in place before she set it down, "I'm basket weaving." she told him with a grin.

"Ha ha ha, your so freaking hilarious." he muttered as he walked over to the table, "If you ruin one of my guns there will be hell to pay."

"I wouldn't have taken it apart if I didn't know what I was doing." she assured him, "Plus, I wouldn't have known how to get it apart without some prior knowledge, this thing was a bitch to figure out at first."

Dean raised an eyebrow at her and sat down, "So you know about guns?" he asked, grabbing a couple of parts off of the table to look them over, "Looks good so far."

She scoffed at him, "I'm from Montana, of course I know about guns." she took the parts from him and continued to put it back together. "No one in my family was ever really into guns. My aunt told me that my grandparents never owned any and that the only time she had shot one herself was when one of her high school boyfriends took her to the range once." she shrugged, "A couple of my friends growing up were from big hunting families, I learned a bit from them, but it was one of my exes that taught me most of what I know." she explained.

"I just thought you getting that demon in the chest at the bar was luck or due to the close distance, but you knew what you were doing. How's your long range aim?" He was beginning to sound more awake than before and his eyes watched her hands carefully as she finished putting the gun back together.

She shrugged and gave the gun a once over before pulling the slide back to make sure she hadn't jammed anything, the real test would be the next time it was fired, but she had faith in the skills that there wouldn't be any problems. "My pistol aim at a long range could use some work, give me a rifle though and I'm almost spot on."

"With a scope? That's cheating." he commented, holding his hand out for the gun.

"I can aim without a scope." she informed him as she handed him the pistol. "I honestly never thought I would need good aim for anything. I don't hunt and I knew that if I ever needed to defend myself in a situation where I did have a gun, that my target would be close enough for me to have to be completely blind to have to miss."

He chuckled at her last comment, "Yeah, you're right, but having good aim is still a good skill to have. Even more so now that you've been dragged into this life. There's a shooting range in here where you can get some practice in." He set the gun back on the table in front of her, "Keep the gun. We'll start working on your aim tomorrow. I'm going back to bed."

"Good night, Dean."

"Night." He called over his shoulder as he walked out of the room. Once he was out of her sight, he smiled softly to himself and went back to his room.

After cleaning up her mess, she turned off most of the lights in the library and made her way to her bedroom, the unloaded pistol in her hand. Ana placed the gun on her desk next to her laptop and then fell into bed, finally tired enough to ignore her worries and fall asleep.

-A-

Sam leaned against the kitchen counter, coffee mug in one hand and a newspaper in the other. Even though they weren't hunting at the moment he was still keeping tabs on what was going on in the world. He'd come across a possible haunting the day before and sent word to a hunter he knew could handle it, but other than that he hadn't found much.

Castiel appeared next to him, making Sam jump slightly, "I have information. Where are Dean and the girl?" he asked, not bothering to apologize for his sudden appearance.

"They're both sleeping still." Sam told him as he set the paper down on the counter behind him. "I'll go wake up Ana. You got get Dean." he took the lesser of the two evils with a grin and left the room before Castiel could argue.

There was a soft knock at her door, but Ana ignored it, all she wanted was a couple more hours of sleep. Sam wasn't surprised when she didn't answer, he heard from Dean how much of a pain she was to wake up. Opening her door slowly, he watched her sleeping form for a moment before he walked over to her bed, "Ana, Cas is back and he has some news. Time to get up."

She groaned, "Come on Sam," she plead, "This is the first time in months I've slept without waking up screaming at some point during the night."

Sam smiled softly, "I'm sorry, but don't you want to know what Cas found out? I've already made coffee." he bribed.

"Coffee?" she questioned and rolled over to look up at him, "I see my caffeine addiction didn't go unnoticed by you." she sat up, her hair in a crazy mess on top of her head.

"You drink coffee like it's water, kind of hard to not notice." He teased, "Get dressed, I'll have a cup ready for you in the library." he turned to leave.

"Thanks, Sam." she pulled her hair out of the mess it was in and ran her fingers through it.

He smiled at her, "You're not as bad to wake up as Dean has been complaining about and you don't look like a troll either." he told her before closing the door behind him, hoping that what he'd said would give her the extra boost to get up.

"A what?!" she snapped and got out of bed. She dressed quickly in a pair of jeans and a black Motley Crue shirt her aunt had handed down to her then stormed out of her room, not bothering with shoes. When she entered the library and saw that all three men were already there, her eyes landed on Dean and she glared at him.

"What's your deal?" he questioned, raising an eyebrow. Sam looked between the pair with a small grin, noticing how Ana's fists were balled up at her sides.

"A troll, Dean?" she questioned, tone cold, "Really?!"

Dean looked to his brother before turning his attention back to Ana, he simply shrugged, "What? When you wake up, with your wild red hair everywhere you kind of look like one of those little troll dolls with the crazy colored hair."

She shook her head at him and rolled her eyes before turning to look at Castiel, "What'd you find out?" she asked as she moved to sit down, taking the cup of coffee Sam handed her.

Castiel looked at the three humans sitting at the table and sighed, "It's not good, but it could be worse." he began, "The ritual is called Concordia, its Latin for unity, which in essence is what it does. Unifying Heaven, Hell, and Earth."

"Cas, cut to the chase, why is Ana the sacrifice?" Dean told him.

The angel stood in place a moment, giving Dean a strange look before he spoke, "The ritual itself calls for many ingredients, some of which are hard to come by so hopefully that will buy us some time. The blood sacrifice is very specific, the person used must be a descendant of a witch who survived death and the direct offspring of a true vessel of an archangel."

Dean's eyes went wide, he now understood why his friend was looking at him the way he was. When he looked at Sam and Ana, they both looked confused. He cast his eyes down, hoping that they wouldn't ask too many questions, but part of him knew it was going to happen.

"A descendant of a witch who survived death?" Ana questioned, not noticing Dean at all as she thought about her family. "I don't recall any stories of anyone in my family being witches."

Castiel turned his attention to her, "During the period of the Salem witch trials, there was a powerful witch by the name of Sarah Good. Among the other women and men who were hung unjustifiedly, Sarah Good was convicted and sent to be hung for her crime. Being the powerful witch that she was, she made a life like duplicate of herself and wasn't actually executed." he explained.

"So this Sarah Good, is…"

"A very distant great grandmother on your mother's side." Castiel told her. "She left Salem the night it is recorded that she died, moved to the Province of New Hampshire. She married a man there and soon had a daughter. I made sure that the information I received was correct."

Sam cleared his throat, "So if her mother is her relation to the witch, then that means that her father is the true vessel of an archangel." he glanced at Dean, remembering their time dealing with Michael and Lucifier, "Do you know which archangel?"

Castiel glanced at Dean before turning his attention back to Sam, knowing that what he was about to say wasn't going to be pleasant for any of them, "That's another thing that the ritual is very specific about. The man has to be a true vessel of the oldest of the archangels."

At the information Sam's eyes went wide, "Michael."

The name drew Ana's attention out of her clouded thoughts thinking about being related to a witch and her eyes landed on Dean, "The true vessel of Michael." she almost whispered. Anyone with Winchester blood could be Michael's vessel, she knew that, she had watched their brother Adam's body house the angel, but Dean was the true vessel. Before she said anything more she was thrown into a vision with a force she hadn't experienced with the others.

The first thing she noticed was a familiar black Impala, a young Dean behind the wheel with a young blonde girl sitting in the passenger seat. It was her mother, she looked so similar to the last vision she had of her that there was no question about it. She watched as they laughed about something before the look on Dean's face turned serious.

"Steph, you know I don't want to go." He told her, the look in his eyes pleading her to understand.

Her mother, Stephanie, nodded, "I know, but I also know you can't let your family go on without you."

The look in his eyes saddened, "Technically you're family now too." he said, glancing down at her flat stomach.

"You said it yourself, we don't know each other that well and whatever your family does is dangerous." She gave him a soft smile, "We'll be okay and if you decide one day you want to meet her, I won't keep her from you."

Dean laughed, but it wasn't a happy sound, "What if she is actually a he?" he questioned.

Stephanie grinned, "For as far back as my mother can remember we've only ever had girls in the family." she told him.

"It will be better for her if I don't come around." He said, "I don't want her to be in danger."

The vision was suddenly gone, she noticed that Sam was crouched by her side giving her a worried looked. She felt a tear slide down her cheek as she raised her eyes to look at Dean who was still sitting across the table from her, "You knew." she bit out, standing out of her chair quickly, "You knew and you left!" she yelled.

Dean dropped his head into his hands, "What exactly did you see?"

Ana bit back a whimper as the pain of this new information hit her, she had always assumed her father didn't know about her, not that he knew and stayed out of her life. "You were talking to my mom in the Impala. You were talking about me."

"She had told me a couple days before that she was pregnant. We hadn't been dating and you just… happened." he sighed, "I had told her before hand that I wouldn't be in town long, that my family traveled a lot and we would probably be gone within a week or two. When she told me, she said that she didn't expect me to stay around. I didn't tell her anything about what we actually did, but I told her that it was really dangerous and any child that I raised would be in that danger too." He looked up at her and stood, "Steph, she understood. God, she was the most accepting person I have ever met and she didn't seem to hold it against me at all when I told her I wouldn't be coming back."

Ana listened quietly to his story, but it only fueled her hurt and anger, "How could you leave her? She was an eighteen year old bringing your child into this world and you left her alone!" she snapped, "So much for your dedication to your family, Dean!"

"I left for you!" He snapped back, hurt in his eyes, he never wanted to have this conversation, "I didn't want this life for you, the constant fear of what's out there, and I didn't want to put your mother in danger either! I knew you would be better off without me! You would be safer if you never knew who I was!"

"And look where that got me." she growled between gritted teeth. "I can't do this, I'm leaving." she quickly turned to leave the room, but was stopped by a strong hand. When she looked up, she was about to snap at Dean again but she realized it was Sam.

"You can't leave the bunker, Ana." He told her softly, "It's not safe."

She gave a curt nod, "I know, I wasn't planning on leaving the bunker, just the room." she assured him as she glanced over his shoulder at Dean who just stood, watching them.

Sam let her go, waiting for her to be a ways down the hall before he turned to look at his brother, "This is why you've been acting so weird. Why you tried to push her to go back to Montana." he was beginning to put the pieces together, "When did you figure it out? When you were looking her up on our way to Jody's?"

Dean nodded, sitting back in his chair with a look of utter defeat.

"Why didn't you tell us?" Castiel asked, sounding hurt. He didn't understand why this was something Dean would keep to himself or why he wouldn't have told Ana after they had met.

He rubbed his hands over his face then looked up at Castiel, "Leaving like that, knowing that Stephanie was pregnant with my child, was one of the hardest things I've ever done." he said, before he turned his eyes to his brother, "Through all of the crap we've been through, losing Dad, Jo and Ellen, Bobby… through all of that, one of the only things keeping me going was knowing that I had done the right thing by keeping that child out of this and keeping them safe."

"She has a point, Dean, look where that got both of you." Sam sat down next to his brother, "I understand why you did it, but you know what being part of this family is like. Bad is bound to happen."

"You should have told us when we found out she was going to be sacrificed, it could have saved a lot of time." Castiel pointed out.

Sam scoffed, "Hell, you should have told me years ago or at least when we met her at Jody's. It explains why she's been having visions about us, though we still don't know why she's having visions in the first place.

Dean shrugged, "Some people are just psychic."

"That's not the case with Ana. It's her relation to the witch, Sarah Good. I found out that she was a natural witch, there was no deal with a demon, no one taught her, she just figured it out. Because she was so powerful, part of the power has been passed down through certain generations of her family. It's also the reason that all of the children of the line are female, she did a ritual to ensure that." Castiel explained as he moved to join the brothers at the table.

Silence fell as Dean and Sam processed the information. All Dean could think about the hurt look in Ana's eyes before she left the room. He had never meant to have any children, especially not at that age, but he hated knowing that to keep her safe he had to leave her. Family was family and Dean Winchester didn't leave family behind.

"She hates me." He broke the silence, not speaking to anyone in particular.

Sam shook his head, "I don't think she hates you. She's hurt and probably confused, give her some time to herself.

-A-

When Ana reached her room she closed the door quickly behind her before she completely fell apart. She let the pain that she had kept at bay in the library slip in and take over, her body shook as she sobbed. Her legs gave out underneath her before she could make it to her bed, so she curled up on the floor, covering her face with her hands as she cried.

It was a long few minutes before the sobs slowly turned to whimpers and the tears quit flowing from her eyes, but she didn't move from where she was on the floor. Between the lack of sleep and the exhaustion that crying like she had been brought on, she was zoned out so much that it took her a while to realize that she'd given herself hiccups. They weren't hard to ignore with the state of shock her mind was now in, the hurt was still there, but her brain was working overtime to try and process everything she had learned in the short amount of time she had been in the library. Trying to process it all quickly became too her and her body shut down, falling asleep on the floor.

-A-

Hours had passed and Ana hadn't come out of her room causing both Sam and Dean to start worrying. "That's it, I'm going to check on her." Dean said, pushing himself away from the table, "I don't care how mad she is, she still needs to eat something." he grumbled as he quickly made his way out of the room.

Sam put down the book he had in his hands and looked at Cas, they had finally found the books that referenced the ritual and they had been reading up on it since Ana had left the room. "You think he realizes he's already acting like a father?" he asked.

The angel smiled and shook his head, "But I'm sure if you brought it up, he would deny it."

Dean stared at her door before knocking, "Ana?" he slowly pushed the door open, "Look, I know you're mad, but you've got…." he paused, seeing her on the floor. Panic quickly filled him as he moved to her side, "Ana!" he rolled her over on to her back, looking her over. She pushed his hands away in her sleep and he realized that she wasn't hurt, just passed out. He let out a sigh of relief and then frowned at the dark mark that was slowly turning greenish on her neck, "At least it's healing." he muttered to himself.

"Come on, Ana, sleeping on the floor will make you sore." he said, shaking her slightly. The girl grumbled something he didn't understand. He shook his head and moved his arms underneath her, easily lifting her off of the floor and caring her the short distance to her bed. Kneeling next to her head, he grabbed her blanket and covered her with them, "I'm so sorry, kid. I never wanted this life for you." he whispered, brushing a soft hand over her hair before he stood and walked toward the door.

"Dean?" she opened her eyes a little, not fully awake.

"Yeah?" he stopped, turning around to look at her.

There was a pause as if she hadn't heard him, but then she snuggled into her pillow and muttered, "You owe me eighteen years worth of birthday presents."

Dean chuckled softly, realizing that she was talking in her sleep, "I'll work on it." he told her, before leaving the room and closing the door behind him.

So that happened! I was really hoping that this new plot twist wouldn't be obvious from the beginning, so please leave reviews! I would love to know what you think about this, good or bad!

Thanks for reading. :)
