Hello, lovelies! Sorry for the absent authors note in the first chapter- so, just so you know so far my co-author (Grace) and I have the first nine chapters planned out, I just have to write them. R&R is greatly appreciated, and I thank the two people who have favorited this story already.

"So you three are hunters. Like- demon hunters. Well, I mean- hell, is there any proper name for it?" Grace asked the other three people in the room, shocked.

"Uh... Yeah. That's us." Sam was just as shocked as her. The looks on both of their faces were undeniably parallel.
Who runs into a coincidence like that?
After a couple more minutes of almost painful silence, Dean turned to Copper. "So what's the news?"
"On?" Copper asked, tilting her head curiously.
"The hunt."
"Oh." She narrowed her eyes, still trying to put together bits and pieces. "There's nothing anymore as far as I can tell," Copper reported, but she did have the same feeling as Dean- the hunt didn't feel like it was over. It wasn't a human spirit, so they did everything they could to get rid of it since there was no way to find a body. The girl could tell that Dean was still uneasy about it, and nothing she said would change that.
"Alright. We'll leave tomorrow," Dean confirmed, laying back on the bed and let out a sigh.
Grace was a little disappointed to hear the three of the would be leaving so soon. She'd be alone again, but that's kind of what she was used to.
"So, Grace, if you're a hunter, what were you doing around here?" Sam asked her. Had they really missed something? Grace had obviously been on a different case- she had a knife wound, and Dean had a ghost-dog bite.
"Hunting down Vamps. You?"
"Not sure. Some kind of animal spirit. Copper seemed to be familiar with it though..." He turned to look at his friend, and if asking her opinion on what it was.
The younger girl shrugged. "That's all it was. I've never heard of a violent one before, but there's a first time for everything."
"How on earth do you know about something like that when no one else does?" Grace asked her suspiciously.
She shrugged again. "I grew up on a farm. When you hear animals that you know you don't have, you just assume animal spirits can get lost too."
"Alright, sounds reasonable." Grace accepted that answer. She stretched again and headed for the door. "Thanks for helping me," she said, waving to them for what she thought would be the last time, and walked out the door. An animal spirit... Wonder how you get rid of that. Grace thought to herself.
The girl crashed down on her bed, suddenly realizing how tired she really was, when it hit her. She'd hunted down an animal spirit before, just like the one they'd talked about back there. They were called keepers- they weren't animals really. They just took the form of them. Keepers locked part of their DNA in some living creature- as many as they could so they wouldn't die. They liked farms- they didn't get caught there. Keepers would attack, but not kill unless someone else had tried to kill them first. Dean had a bite on his leg... A dog bite...
Grace had drifted into a comfortable sleep.
Her eyes flew open. Dean had a bite- the keeper's DNA was in him. It was going to track him down and kill him, because Dean had tried to kill it. She'd seen it- in her dream. A little while back her psychic things like mind reading and premonitions had stopped for awhile, but they had started up again a couple months back.
Grace leapt out of bed, grabbing her handgun with silver bullets, running outside.
She saw them- light, dusty paw prints leading to the Winchester's door, passing right through it. It was already inside. Grace pounded on the door, screaming "Sam, let me in!"
It was hardly ten seconds before the door flung open, revealing a panicked, shirtless Samuel Winchester. "What?! Are you okay!?"
"I am, but your brother's not," Grace snapped, pushing him aside. Dean hadn't moved- he hadn't even stirred when she had pounded on the door. A faint shimmer of the outline of a wolf- the keeper- floated above him, and a dark red mist was running out the sides of him mouth. The keeper was suffocating him!
"Oh my God-" Sam began to move towards his brother, but Grace motioned to him to stay where he was. One shot rang out. Then another. The first bullet had brought the keeper into full focus. The other killed it- making it disappear on the spot. Surely it wasn't dead- keepers were impossible to kill, but it wouldn't be after Dean again.
Once the keeper was gone, Dean's eyes flew open as he jolted upright, gasping for air.
"What the hell-!?"
"I just saved your life." Grace said flatly, putting her gun away.
"From what, exactly?" Sam asked, putting a hand on Grace's shoulder, turning her towards him a bit. She relaxed again under his hand- he seemed like someone she could trust.
"A keeper- it isn't usually a problem. It should just attack other animals unless it's provoked..." Grace continued to explain everything she knew about the to Sam and Dean, when a girl spoke up behind her in the doorway.
"Wow- I go to buy y'all breakfast, and this happens. Dean- are you okay?" She asked him. He did look a bit shaken, but he shook his head to dismiss the question.
"Yeah, I'm just super." He said sarcastically.
Copper rolled her eyes and walked over to sit next to him. "Yeah, you're fine." The two of them continued to tease each other, in some sort of friendly manner. It was like watching a brother and a sister argue. Then Grace realized a possibility- the two of them could have some sort of relationship.
She looked up at Sam, curiously. "I know it's not my place to ask, but do those two have a thing or something?"
Sam looked down at her, not expecting that at all. He looked a little surprised. "What? No, I don't think so. God, I hope not-" he shut up after he said that.
Grace caught it. "You hope not?" She asked, raising her eyebrows. Sam looked really defensive, so before he could say anything, she smiled reassuringly. "Calm down mate, I'm just teasing you."
Sam was trying not to blush furiously, so he started to turn away when Grace snickered.
Dean looked over at them, eyeing Grace suspiciously. "How did you know?"
"How did I know what?"
"How did you know that thing was in here," Dean clarified.
Oh, shit. Grace thought to herself, blushing. She didn't like to tell people about her powers- especially not other hunters. They always became suspicious of her, and if they didn't think she was some sort of supernatural creature, they would cast her away. She groaned inwardly. "A- a premonition," she answered reluctantly.
"A what?" Sam didn't think he'd heard her right.
"Yeah. I can sort of read minds too, so I know you're not really surprised."
Sam blinked. He hadn't told anyone yet, because he'd thought they had just been dreams, but he'd been suspicious of his powers returning for awhile now. If Grace had them too...
Dean glanced at Sam. "You don't think...?"
Sam nodded. "Actually that's exactly what I'm thinking. Grace, when is your birthday?"
"May second. Why?"
May second? Okay, um... That was a really big, really weird coincidence.
"What year though?" Sam pressed.
"'83. Why?" she stressed.
Sam and Dean exchanged uneasy looks. Grace looked at them curiously. They didn't know about the special children, did they? Most, if not all of them were dead today- somehow, she was the only one who managed to escape when they were all brought together.
Quickly she voiced her question out loud. "Do you know about the special children?"
"Yeah, we do." Copper answered. "Sam-" she began, cut off by Sam.
"I am- well, yeah. I am one... But what are the odds of sharing the same birthday?"
"I dunno, mate. I never knew my brothers, so, who knows?" She teased, lightheartedly.
"Oh- what happened to them?" Sam and Copper asked at the same time.
Grace shrugged. "My dad- my real dad kept them with him, I think. I was put up for adoption after my mom died in a house fire."
"... What the hell!?" Dean stood up, walking over to her, while everyone else was looking at the girl in a stunned silence. "Grace, what is your name? Your real, full name?" He asked her, looking her directly in the eyes.
"Grace Winchester."
"Son of a bitch," Dean.
"Holy shit," Sam.
"Uhm..." Copper.
Grace looked between the three of them. "Did I miss something?"
Sam and Dean were a little too shocked to explain it, so Copper spoken up. "You share the exact birthday as Sam, and have an extremely similar backstory to the two of them, and have the same last name... Grace, there is a possibility that you could be their sister. I mean- you never knew your brothers."
"What the fuck?"
"Yeah." Sam breathed out. "But, come on. Wouldn't dad have told us if we had a sister?" He asked, turning to Dean. "Wouldn't you have remembered?"
Dean didn't speak at first, making Sam and Grace feel uneasy. It wasn't possible, was it?
"Grace, where were you born?" Dean asked her seriously. When Grace looked like she was going to answer with a question, Dean repeated the question. "Where were you born?!"
"Kansas," the girl answered quickly.
"Yeah, Sam. She's our sister. You had one- a twin sister, until mom died," Dean told his brother guiltily.
Sam didn't know how to react. "Dean- what the hell? Did you not think that this would be important? I'm serious!" He lectured his brother accusingly. "What, did you honestly never think of this!?"
Grace fell back next to Copper who was watching the two brothers bicker with hidden amusement.
Dean put up his hands defensively. "I'm sorry Sam, if you haven't forgotten, I was four the last time I saw her! Dad never talked about it!"
"Did Dad really never talk about it, or did you just never ask?"
"Dammit Sam, can't you just forget about the details this one time? She's right here. We have a sister, and hell, I'm going to celebrate by taking her to get a drink. Do whatever the hell you want, just quit bitching about it every time you find something I never told you!" Dean sounded like he was done with that conversation, and he wasn't going to take another word of it.
Copper looked down at Grace with a reassuring smile. "Don't worry, they don't do this too often."
"Oh, I'm not worried, mate. I'm just surprised I actually found them- on accident too. What are the odds?"
Copper shrugged. "Three hundred million-in-one?"
Grace laughed.
"Alright, Dean. I'm sorry." Sam had given up on the argument that had apparently continued.
"Good, so are you going to come or not?"
Sam shook his head. "I'll catch up with you guys later- I just need some time to think.
Dean shrugged. "Fine. Grace-" he said, turning to the girl who was apparently his younger sister, "do you want to come grab a beer with me?"
Grace shrugged. "Sure, sounds fun."
In a few minutes, the two of them headed out, taking the impala. Copper walked over to Sam, who had gone to sit on one of the beds. He was a little surprised she was still here.
"You didn't go with them?"
"No, I can't drink," Copper reminded her friend, sitting down next to him. Copper was the youngest of all of them- she was only twenty. She'd met both of the Winchester boys when she was eighteen, before she went to college. It was a complete accident, but they were all glad it happened in some way or another. Copper was probably Sam and Dean's closest friend, and for that reason, she cared about both of them. Sam obviously wasn't taking this discovery as well as his brother. "Are you okay?"

So, that's that.

You know, if any of you have any ideas or guesses as to what might happen later on, I'd love to hear what you think. Thank y'all for reading this- it means a lot to me.
