"Jack? What happened?"

Sam was lost between Jack's muttering and the fact that he rushed out so quickly.

"I don't know what happened. There were demons, three of them. They wanted to, to find Y/N. I used my powers to push them away. I don't know how, I haven't been able to use my powers since… Anyway, Y/N ran in and killed them. And then, she said she was going home and… and disappeared."

"You mean she teleported?"

"Yeah."

Sam set his eyes on the road. "We need to find this girl."

"How?"

"We'll find a way."

Local therapist found dead in her office.

Therapist murdered in Belleville, Kansas.

Strange murder of a Kansas therapist a week ago.

Dr, Myla was dead. Because of you. Because you kept coming back. Because she was one of the few things keeping you sane. Because you were bad luck and you would always be bad luck and you just wished you could…

You could just die.

But you can't.

There was a knock at your door and your immediate response was to grab your knife. Maybe it was just a neighbor looking for sugar. The homeowner looking for rent. Some seller or converter.

But you could never be too careful.

You slid the knife into your back pocket, hoping it wouldn't ruin the pants and slid the door open a smidge. Outside was something probably worse than demons or angels coming to kill you.

"Y/N L/N?" Sam Winchester asked.

Behind him was Jack, looking curiously at you and you could feel… relief from him? Behind them was another man, a dark haired man. An angel, you corrected yourself as you noticed his heavenly shape beyond the vessel he put on.

"You… shouldn't be here," was all you could get out.

"Y/N," Jack said. "Don't worry. We're here to help."

You shook your head. "You can't help me. And you really should go. I'm dangerous. I could attract demons at any minute so please get out of here."

"Y/N, we can't go," Sam interjected. "We need your help."

You looked at him skeptically. "Well sorry if I don't take your word for it, but you do have an angel behind you who radiates anger."

Sam turned to look at the angel before turning around and looking at you helplessly. "That's Cas. I promise he's not mad at you. He's just dealing with some things. Can we come in?"

He didn't look like he planned to harm you. In fact, he looked very sincere and pretty scared. But, you looked to Jack for any tell otherwise. And he looked at you with so much hope in his eyes you were overwhelmed.

The feeling swelled throughout your whole body and you tried not to get pulled away. You took a step back reeling from this sudden feeling of connection between the two of you and shook your head.

What the hell, you thought. I'm dead anyway. Might as well just throw everything I know out the window.

"Sure," you said and stepped away from the door.

You sat down on your couch and simply stared at your feet as the three of them filed in. You waited for one of them to speak up.

The angel, Cas, slowly walked toward you and you caught his gaze. Although he still seemed angry, he didn't look like he was going to hurt you. So you didn't run. You did scooch away from him slightly while he approached, leaning back in your chair as bent down to look at you. You held your breath as he looked into your eyes and searched for something.

"You were right," he finally said, backing away. "She's the one."

"The one?" You asked. "The one for what?"

"Y/N," Sam spoke again. "I'm sure by now you know who we are-"

"I've known since you walked in to pick up Jack from his first appointment. I've been told to look out for you Sam. And your brother."

He pursed his lips. "Who told you to look out for me?"

"My father."

"Oh, so you know your father?"

You rolled your eyes. Of course you knew your father. He had been watching you from the moment you were born, waiting to use you for his master plan. But his plan had failed. He died desperate to find Jack and to serve Lucifer.

"What do you want from me?"

Jack took this opportunity to move and sit down next to you. "We just want to help you."

"No you don't. If you wanted to help, you would leave me alone. I can fend for myself. But no, you want me for something. Or else he wouldn't have called me 'the one'." You pointed to Cas, then turned to Jack for an excuse.

It was Sam who responded. "Y/N, we know what you are."

"A Cambion," Cas finished.

You jolted when you heard the word used. You had never heard anyone say it out loud. Your mother didn't know and your father only ever called you "special" or "one of them". But you had read all about what people like Cas called you.

"You caught me," you replied and blinked, changing the lense of your eyes to flash them with a classic, black-eyed demon look. Your father trained you how to do that when you were with him, supposedly so that he could show you off like some prize. A demon child who was so much more powerful than him or any other demon known.

Sam and Cas took a step back, looking at you, but Jack stayed by your side. When you went back to your normal eye color, Jack gave you a small pat on the shoulder.

"It's okay, Y/N. We aren't afraid of you and we aren't here because you're a Cambion."

Cas's lip twitched. "Well, no. That's exactly why we're here. We need your power."

You shook your head. "You don't want my power. It's no good. All it does is get me in trouble. And why would you want me when you have a Nephilim living in your very own house?" You gestured to Jack and he looked down onto his hands in his lap.

"Jack's… not feeling well. And we aren't sure he can do what we need him to by himself. So, we were looking for something else. Something just as powerful. And Jack told us about you. About what you did last week in the therapist's office and we were hoping you might be willing to-"

"Be willing to what? Play superhero for you while the main man is resting? I don't hunt and I don't want to, so can you just-"

"We don't want you to hunt." Cas looked at you sternly. "We want you help us save Dean Winchester. And stop the archangel Michael."

You laughed out loud at that. "I knew you guys were crazy but this is on a whole new level of insane."

You went to stand up, but Jack grabbed your arm. "Y/N? Please just hear us out."

"Hear what out? You want me to save Dean Winchester? I don't even know what's happened to him, but if you guys can't save him, he can't be saved. And me? Defeat an archangel? I can't even beat my father and supposedly I'm stronger than a demon. Yeah, well that didn't work. And you know what else didn't work? Hiding myself from you guys, so no. I don't want to hear you out, I don't want to be a part of your plan that will most definitely get me killed, and now I can't even stay in my own house. If you can find me, so can others, and I really should go."

You got up and tried to walk around Sam and Cas, but they stopped you.

"Please Y/N. You are our only chance," Sam said.

You shook your head. "Don't place your bets on someone like me."

"Why not? You say that you can't defeat your father, yet you have the most powerful cloaking against angels or demons I've ever seen. Even after your powers got completely out of control, Cas couldn't track you down. The closest he could get was a 15 mile radius around the therapist's office. We had to search all kinds of apartment and rental buildings owners just to find you and now you're going to tell me you're not powerful? Jack said you can teleport and that you knocked a blade out of a demon's hand. At least, give us a shot. We aren't perfect, but we can help protect you and we need to do something. We don't have any other cards to play."

You sighed and stepped away from him. "What would you even have me do?"

"We first need to seperate Michael from my brother. Dean is Michael's vessel as of now, so that's the beginning. That doesn't necessarily require you, but you would probably be helpful to have. Then, after that Michael will try to find a new vessel. We need to stop him. Michael is extremely dangerous, but we don't know his goals yet. So, we need to figure out what he plans to do and prevent him from it. Jack is the only person we know of with the power to defeat someone like Michael…"

"...But I'm drained," Jack finished.

You looked at him curiously. "Drained? I just saw you use your powers against those demons."

He sighed. "That was the most I've used of my powers in weeks. And it left me completely exhausted. At the rate I'm growing in strength, I won't be strong enough to beat Michael before he takes over."

"And," Cas added, "killing Jack is probably pretty high on Michael's list of things to do right now. He knows how strong Jack is, but he also knows how vulnerable. He'll want to get him out of the way fast."

"So you need me to…? Stall for time?"

"We need you to help us beat Michael."

"Well then you're wasting your time."

"Consider it," Sam said sternly. It was the first time Sam had said something harsh to you and you flinched. Something in you sparked once again.

Hunter.

Sam Winchester was a hunter and hunters killed people like you. Monsters like you.

His face softened. "I can't force you to help us. But I'm desperate. So desperate to get my brother back. Please, just… I will do anything."

You sighed. You wanted to help, you really did. But you were… you. You were born and raised to be a monster. It was probably best for you to stay out of everyone's way. And you couldn't just leave your home.

"I wish I could help, Sam Winchester, but I really don't think I'm the girl you're looking for. But I guess…" You shook your head at how crazy the deal you were about to make was. "Let me stay here. In my apartment. Let me work alone. And only call me when you need me. And I'll tell you if I can do it, but if I can't, you leave me alone. I'll call you with anything I know of, but it will probably be nothing. Now, get out of my house."

He nodded. "That's all I need."

You had gotten three calls from Sam. You never picked them up, too afraid to listen to him. To talk to him. He never left messages which made you think he didn't need you. He was just… checking in? Updating?

It didn't matter what he wanted, you remind yourself, because he shouldn't be calling unless there was an emergency and if that were true, he'd leave a message.

You didn't look. Didn't search. Didn't try at all. You weren't going to help unless you needed to and you weren't even sure why you would help them then.

It's been over a week since they found you, invaded your home, and argued with you.

… Argued? It wasn't an argument. They were desperate.

You shook your head. Who am I even talking to right now?

You were walking home when a loud clap startled you. You turned to find the source, but came up empty handed. No one was there.

You tried to shake yourself of the sudden fear washing over you, but you couldn't. Something was wrong.

For the first time ever, you sensed an emotion before you saw the person.

Rage.

You teleported yourself home, not caring to check your surroundings for for anyone watching, but it didn't matter.

Your apartment was destroyed. The TV smashed, the couch torn to bits, and every chair overturned.

You stepped carefully around the crushed glass from the TV screen and went to the kitchen. Same story. All the plates smashed and the knives standing upright, having been stabbed into the sodden table.

On the floor there was a note:

10 days.

You knew they handwriting, you knew the person who wrote it, and you knew who brought the letter here.

"Eva."

A woman stepped out from the shadows of the door that led to the restroom. She was a tall blond girl, wearing a suit, with the same smirk on her face that she had 6 weeks ago when she showed up at your door with a similar message and two demons in her wake.

"Hello again, Y/N. You're home early," she said, in her high pitched, unassuming voice.

"I wasn't expecting guests."

"Oh. Don't worry. I'll be done shortly." She turned on her heel and walked back into the bathroom. There was a loud crash and suddenly she appeared once again, brushing off her hands.

"All done," she said with a smile and then left, brushing past you as she walked out the front door.

You picked up your phone.

It's time, you thought.

Ringing… ringing…

"Hello?"

"Sam? It's Y/N."

"What's up? Have you found anything?"

"No. But I need a place to stay."

"You're telling me, your dead father has been sending you letters through a demon named Eva, who just overturned your house and threatened you to get out?"

You shook your head. The impala was hot and you leaned out the passenger window as you and Sam flew past each town towards, what you could only assume to be the bunker.

"She didn't threaten me, but I'm no longer safe. If my father told her to shake me up, obviously something big is coming."

"In ten days," he added. "That has to do with Lucifer?"

"It must. My father raised me to be Lucifer's puppet. Prepared me all my life for this. What's ten days from now?"

Sam shook his head. "It's nothing. I checked on the way here and nothing exciting or slightly unusual is happening so I don't understand. Lucifer's dead so-"

You jolted upright in your seat. "Lucifer's dead?"

Sam nodded, obviously not noticing your discomfort. "Yeah. That's the whole reason Michael has Dean. We needed to stop Lucifer so Dean made a deal to be Michael's vessel or whatever and Michael went back on the deal and after Lucifer died, he kept using Dean."

You stayed silent, watching the car continue to drive through the long stretches of empty land and thinking.

Lucifer is dead. Your father, and now Lucifer. You should be happy, ecstatic that the two men who were supposed to ruin your life could no longer hurt you, but all you felt was empty.

"Y/N?" Sam asked. "Are you alright?"

You tried to shake yourself from the trance. "Yeah. I'm fine."

"That is the look of someone who is very obviously not fine, so why don't you tell me what's wrong."

"... My father. When my mother died, he took me to hell to live with him. That's how and why I know him. He caged me down there for 6 years and he wasn't even there half the time. He hated hell and refused to associate with it, but he wanted me to live down there. Said I might as well. While I was down there, I learned about my purpose. Demons don't have children for the sake of having a child. They don't like that anything they birth will be more powerful than them. They do it only, and solely, for the purpose of creating an army for Lucifer. My father wanted me to be the best soldier in that army. He claimed that I would one day be the right hand man to Lucifer and so that's how I lived. Training, learning, breathing, to become a hollow shell for Lucifer to inhabit and, when the time came, to be the downfall of Heaven and the angels. When I found out my father was dead, and that I was free, I practically cried from relief. I tried my hardest to live a normal life, but that's not really possible for someone like me, is it? Anyway, I got into therapy and found a life, if not a normal one, up until I got that first message from Eva. Soon, it said in my father's handwriting. And I knew that my destiny was far from over… but if Lucifer's dead. Really dead… I don't know. What am I here for?"

Sam smiled at you from the driver's seat. "Oh, believe me, you have a purpose. And you're gonna do some real good. I know."

You guys approached the bunker in silence and Sam led you inside and through the halls to your room.

"Here you are Y/N. It's pretty bare, but it will do. You can put whatever you want in here."

You put your two bags with clothes and everything of yours that Eva had not broken on the bed and turned back to Sam.

"It's perfect. I mean, I am the girl who lived in a cage in hell for 6 years, so I'm not picky, but it does mean a lot that you'll let me live with you, so… thanks. For everything."

He smiled and you could feel all the tension and weight between the two of you lift. The fact that Sam was hunter didn't seem so threatening anymore and you didn't look like just a demon to him either.

You turned back to your stuff and sighed. "Don't have much to customize my room with, but that's all good. I probably shouldn't get too comfy anyway, don't want to overstay my welcome."

Sam shook his head. "You're going to be a great help to us, Y/N. You can't overstay your welcome. And about the decor, I can't help you much about that, but if you want me to stop by the store for something, don't hesitate to ask. I mean, i don't have enough money for some tricked out lounge, but a rolly chair I can do."

You laughed. "I think the wood chair that's already in here will do, but thanks for the offer. I can't take your money though."

He nods. "I understand. Just remember that the offer is on the table. Now, Jack and Cas are probably waiting for us in the kitchen, so let's head down there. I'm sure Jack will be happy to see you."

Sam was right, about both them being there and Jack being happy to see you. The first thing that happened when you walked in was Jack engulfed you in a hug.

"Y/N! Sam said you were staying with us?"

You smiled at him politely, taking a step back after he released you. "Yeah, until I can find another place." You stepped around the older boy and towards the table Sam and Cas were sitting at.

"So, what's the plan?"

Cas looked at you suspiciously and you realized that even though you may have made up with Sam (and you never argued with Jack), you were still the new guy, and not even that, you were basically the bad guy.

"We need a way to separate Dean from Michael," he said turning to the drink in his hand, like he couldn't be bothered to look at you.

You sighed. This might take a while. But, you were a demon, so he didn't have to like you.

"Well, that's simple enough," you state.

"Simple?" Sam asked, obviously not on the same page as you.

"Of course," you explained. "You guys have tons of spellbooks here. I'm sure one of them contains a spell to separate an angel from his host."

"You can do that with a spell?" he asked again.

You nod. "Yeah. I've heard of it, at least. It's a strong spell. It will require a witch to cast it-"

"Rowena," Cas said, interrupting your train of thought.

"Oh no," you start again. "I can cast it. But I can't imagine the ingredients it requires."

Sam looked at you confused. "We can get whatever you need, but Y/N are you sure you can do it? We have a friend who can-"

"Oh yeah, don't worry. I've been using spells and witchcraft to help protect myself for years. But first, we need to find that spell."

"I've got something." Sam stood up from his spot at the table and walked around to show you.

You guys had been searching for this spell for three days. It was pretty rare and the boys had a lot of spell books, so you guys spent your time slowly flipping pages looking for anything promising.

Sam put the large crimson book on top of the one you had previously been looking at and pointed to what he was talking about. "It says 'Vessel Detachment Spell'. Do you think it will work?"

You looked over the page. "Yeah. I can do this. It's… it's possible. But, there's a problem."

Sam leaned over you. "There's always a problem. What is it this time?"

"One of the ingredients is the blood of the vessel. You need Dean's blood to do this spell… A good amount of it. You wouldn't happen to have that lying around, would you?"

Sam sighed and shook his head. "No… So, how would we get it?"

"The only solution I see? We've got to injure Michael. Enough that Dean is bleeding and we can get at least a vial full of it, but not enough to kill him. This separation spell won't do us much good if Dean dies before we do it."

Sam nodded. "Okay. So, our next goal is to find Michael, get that blood, and do this spell. I'm on it."

Sam left, and you pulled the book forward, looking over the ingredients and requirements once again.

It was possible. The rest of the ingredients were things like witches' hair and blessed stones. Not easy, but you believed in Jack, and Sam, and maybe even Cas. But there was one thing you knew. No one could survive being the vessel to Michael. Not even Dean Winchester.

Sure, if Michael were to willing walk away from Dean, then yes, he'd be fine, but to rip one of the most powerful archangels in existence from a human man, it would kill him.

You read over the spell once more. This spell should only be done within the beginning stages of possession. There is no guarantee of the survival of the vessel.

"Hey Y/N," Jack said, walking in. "Sam said you guys had found a spell, so I brought you some hot chocolate to celebrate."

You looked to see Jack was indeed holding two mugs of hot chocolate and you couldn't help but smile. He had always been so sweet and innocent.

"Thanks Jack." You reached out and grabbed one of the mugs from him, which he happily let go of.

"Are you okay?" he asked, stepping closer. "You seem tired."

You shook your head. "Nope. I'm great."

He nodded and left you to your drink.

You sighed thinking back to the past couple of days. Sam had been warm to you, treating you like an important member to the cause. Jack had been sweet, always checking in on you. Cas had been… Cas. He was still suspicious of you, but you had learned to shrug it off, and Sam had assured you that it was just how he was.

You were trying to get used to the new environment. You liked not being so lonely, but at the same time, you felt more detached from the world than you had before. You never left the bunker, never went outside, and you felt like you had to be more careful. You had some things you couldn't tell the boys.

You got up from your chair and walked back to your room. The room was basically the same as it had been when you arrived. All your clothes were in a drawer and the rest of your possessions were still in a duffel bag, sitting on your desk. You didn't really think you should take anything else out. You didn't want to get too comfortable.

You sat down at your desk and looked at your phone. 1 missed call. Sam had given you a funny look when you didn't answer the phone call, but hadn't asked any questions, luckily. You didn't want to explain your situation to him.

You thought about it for a minute. Should you call back the hospital? I mean, they probably won't ask questions if you just disappear. But, you don't want people suspicious of you or on your case yet. And you owe them money for the appointment, whether or not you made it. If they don't suspect anything, people won't notice you're missing for the next week and a half.

You sighed at what that long train of thought brought you to and quickly opened your phone.

Breathe, you thought.

"Hello. This is Dr. Perry's office. How may I help you?"

"Hi. This is Y/N L/N? I'm here because I missed my appointment today."

"Alright, I'll pull that up. What was the appointment for?"

Breathe in, breathe out. "I had a check-up for my cancer growth."

"Here it is. Lung cancer, right?"

"Yep." Breathe in, breathe out. "That's it."

A/N: Hello! I'm so glad you've made it this far into the story. I don't normally make authors notes, so don't worry this won't be a regular occasion, but I just wanted to say that any and all questions and comments are welcome! I'm always happy to hear from you guys so don't hesitate to let me know about any concerns, critiques, or praises you have. Thanks!
