A/N: So... This story is my biggest project so far. It will have four parts, named An Opening Match, The Moves of the White Knight, A Threat on the Black Queen and Checkmate.

The story is about Diana "Chess" Winchester, daughter of John, big sister to Sam and Dean's twin. The story goes on from season one of BOTH shows, this part is seasons 1-2 of Supernatural, drifts into the beggining of 3 at Criminal Minds (Up until Gideon leaves).

At least at first, I'll post once a week, maybe later it will move to more often.

The story is not Beta'd, all mistakes are my own but I'm open to comments about it :)

Disclaimer: I do not own Supernatural nor Criminal Minds.

"All great beginnings start in the dark,
when the moon greets you to a new day at midnight."
Shannon L. Alder

The night was dark and silence. I was in my bed and dad read me a bedtime story about princesses while my mom took my twin brother Dean to say goodnight to our baby brother Sam. Dad finished the story and turned off the light but I stayed awake and waited for Dean to return.

I could hear his cry of joy – "Daddy!" – And parts of their conversation before mom said something and dad brought Dean to our room and put him in his bed.

Within moments, we were both asleep.

I woke up with a start to the sound of a scream followed by the sound of dad, yelling mom's name and running up the stairs.

"No! Mary!"

Dean and I jumped out of bed. I was startled from the flames and the smell of smoke. Dad was shouting and Sam was crying and we ran out to the hall just as dad did, holding Sam in his arms. Dad passed him to Dean and pushed us towards the stairs.

"Take your brother out as fast as you can. Don't look back." Dad said to us. "Now, guys, go!"

He turned back to the growl coming from Sammy's bedroom and Dean and I started running. I tripped and fell. Dean turned and was about to stop but I told him to get Sammy out.

The fire spread through the house and dad ran out of the room. When he saw me, he tried to pull me away but I was too scared to move so he picked me up and carried me away. He ran out of the house and saw Dean standing on the lawn and looking at the house with Sammy still in his arms. Dad lifted Dean up and dragged his three children away.

Just as we were away from the house, the windows blew out with a loud sound.

The rest of the night was a blur, but a single memory stuck to my mind even after years has passed: Dad sitting on his Impala, Dean clinging to him on his right and me on his left. In his arms, he holds Sam tightly and we are all looking at what used to be our house.

That was the memory that crossed my mind when I fought with him that day.

"I don't want this life! I just want to be normal!"

"Well, there's nothing normal you can get here, Dee, so you better leave!"

"You know what, John, maybe I will!"

I saw the pain flashing through his eyes, as it did every time I called him John in the past two years after I stopped calling him "Dad". Sammy was staring at the fight, scared but trying to hide it and Dean stood at the entrance to the motel room.

"Dean, take your brother outside, I need to talk to your sister." John said and Dean automatically obeyed, sending a worried glance at me as they left. I returned a smile and he seemed to relax a bit, but his eyebrows were still stiff and I knew he was worried. Once they were out, John spoke again.

"Why are you doing this?" He asked. "Why are you giving me such a hard time?"

"I'm giving you a hard time?" I asked, disbelieving. "You see me for like two days a year! You just make sure I stay at Bobby's and out of trouble and take the boys to God knows where!"

"I'm trying to keep you safe!" He said.

"Well, I don't want you to!" I paced around the room, annoyed. "I just went to the Roadhouse, to see Ash. Why are you making such a big deal out of it?"

"Just going to see Ash?" John asked. "I'm not an idiot, Diana, I know just what you two are doing in that back room and it was no researching. How did you even get there?"

"I live in a damn junkyard, John!" I yell. "Been fixing cars since I was ten, I just took a motorcycle and went for it!"

He stopped and looked at me with surprise and a hint of pride. "You fixed a Motor by yourself?"

"See! You don't even know me!" I raised my voice again and he stiffened.

"Why couldn't you just stay at Bobby's until you finish high school?" He asked.

"I have finished high school, John!" I yelled. "Three weeks ago! I'm eighteen and a half!"

"So now what?" He asked. "You want to just go? Go to college or Harvard or whatever? Ditch us and disappear?"

"Do not dare put this on me!" I screamed. "You're the one who ditched me! You're the one who left me at Bobby's time after time after time."

"Don't do that, Diana." John said. "It's nothing like that."

"So why did you leave me there?" I asked. "Why did you take the boys and left me there every single time? Why the more I grew the less you came to see me?"

"Because hunting is not for girls!"

I looked at him for a couple of seconds. "I'm not good enough for you, is that it?" I asked. "Just because I'm a girl. Just because I'm not a macho man like you or Dean I worth less?"

"Dee, it's nothing like that –"

"Don't bother." I cut him off, picking up my things and heading for the door. "No one's listening."

"Dee, what are you doing?" John asked as I walked out the door. "Dee? Diana!" He stood at the entrance of the motel room. "Where are you going?" He asked.

"Away!" I called.

"How?"

"I don't know!" I turned and looked back at him. "And honestly, I don't care. I am done with this, with you. For good."

I ran out to the road and did not stop. I kept running for five or six miles before I pulled out my phone and called the first person I could think of.

"Ash, it's me."

"Babe, where are you? You left nearly twelve hours ago."

"Yeah, I had some…" I looked around me at the endless forest. "I had some family business to handle."

"Figured this much out."

I froze at my spot. "Ash. What did he do?"

"Nothing, babe. All's good."

"Ash, if you won't tell me I'll call Ellen and Jo and you can bet your pretty ass they'll tell me." I threatened. "Just spit it out."

"Well, he may have… punched me in the face."

"Oh my God!"

"I'm fine, babe, I'm okay."

"You are not okay, he punched you!"

"Look, I don't matter right now. What matters is the reason you came. You got a scholarship to Harvard, babe!"

"Look, it doesn't matter…" I mumbled.

"Sure it do, babe. You are going to Harvard and that is not a question." There were background sounds from the other end of the line and Ash cursed. "Damn, babe, I gotta go. Talk to ya later."

"Take care!" I called and he hung up. I started walking when a car approached me and a woman pulled over next to me.

"You need a ride?" she asked with a sweet smile.

"Yeah, I…" I hesitated for a moment about getting a ride with a stranger in the middle of nowhere. I decided I am too tired and too pissed to care. "I need to get to Massachusetts."

The woman smiled and I opened the door.

"We are going to get you guys through the last test!"

FBI agents Hotchner and Gideon stood in front of the group of ten candidates applying to the BAU, nine boys with me the only girl. All of us were good enough to get this far and all of us knew we would get good positions once we're done with our training, but we all wanted to be profilers.

"Your mission is to find the Unsub responsible for those killings." Agent Gideon said. "The information is in those boxes. Remember you are a team. You have two hours. Go."

We ran and grabbed the boxes, lifting them to the table. We started spreading the pictures and papers across the tables and going through the information within. Four men who disappeared from parks where they sat with their kids and were found dead 2 days later, after their genitals were cut off while they were alive.

Everybody started shooting ideas to the air, trying to impress the agents.

"There is a lot of suppressed anger in this case; the Unsub might be seeing the victims as replacements to a person who hurt him."

"How do you know it's a 'him'? The Unsub could be a woman."

"A woman who can take out a grown man?"

"Don't take women so lightly, Brian. Chessi can take you out on a fight."

"She had." Someone smiled.

"You're missing the point here." I said angrily. "Andrew said something important and you weren't even listening."

The entire group looked at Andrew who shifted uncomfortably. "I was just saying that all of the kids were boys in the ages 4-7." He shrugged.

"And they weren't touched." I noted.

"So the Unsub might be seeing them as his younger self." Andrew finished.

"So the victims symbolizes his father." Brian said.

"If that's the case he might be going after his father next."

"So he is in danger."

From that point on, the case moved swiftly. Everybody took effort in catching the Unsub and everybody contributed to the effort.

"I heard that once, they didn't find anybody who they thought was qualified, so they didn't choose anybody." Christian said after we were dismissed with the promise that the BAU will make a decision by dinner.

"Maybe it will happen this year, too." Andrew said worryingly. "None of us made a big impact on them. We wouldn't've solved the case without each other."

"We probably could." Brian said. "It would just take us longer and we couldn't save the father."

"That's why team work's important." I said.

"I don't know." Andrew sighed. "I'd rather having one person who would solve the case and then we wouldn't be that stressed."

"And people might die." I retorted. "Well, you boys have fun. I'm gonna take a nap before dinner." I yawned and headed to my room. I looked at my night shed where a picture of Sam and Dean sitting on the Impala with me between them, all of us laughing.

The picture was taken about a month before I left. Bobby wanted to take a picture of us and Dean and I didn't want to, but Sam looked at us with those puppy eyes of his and we gave in. I decided if we are doing it, we should be doing it right, so I forced Dean to smile, it was so absurd Sam and I burst in laughter. The result of that was Dean frowning at the camera, Sam smiling, his eyes shining with joy and me in the middle, laughing so hard I held my stomach in pain and my hair fell on my face.

I was grateful for this picture now. I have changed so much in those seven years of studying Criminology and training to be an FBI agent, changes that only began with my short hair, which I cut on the first day of the Academy. Moreover, I have not seen Sam and Dean for so long I could not even start wondering how they might look by now.

Dean was probably taller and more grown, though not more mature. I wondered if he can ever be mature and decided that probably not, and even if I were wrong, I would not want to meet him all grown up.

Dean was a big child in all means: Trying to act older than he is, being cynical in order to solve problems, refusing to show emotions and in the desperate need of John's approval. And as weird as it might be to believe it, I loved it.

Sam was the opposite - a grown up stuck inside a child's body. What wouldn't I give to see how he will be like when he is a grown up in a grown up's body, but I knew it was not possible. After all this time, the mere thought of seeing my brothers again was only a dream.

The difference was that, in my dreams, I always knew I would see them.

You see, they weren't just dreams. They were… some people would call it prophecies, but is it one when what you dream of happens when you dream it? I knew my fair share of prophets and psychics, and even called one of them, an old friend of John (Which should show you how desperate I was) named Missouri Mosely.

She told me she doesn't know what those dreams are, but they're not prophecies. Nor is it just my imagination.

I headed to bed and had a dream of Dean driving the Impala. He was alone and I was worried. I knew Sam left about three years ago, leaving Dean alone with John, and that John occasionally sent him on solo hunts, and I was scared for my brother hunting without back up. He was alone for a couple of days now, for John was in a hunting trip, but he hadn't called in a while.

When my alarm clock rang, calling me for dinner, I stumbled out of my bed, worry clouding my mind.

I guess that is why I didn't hear when my name was being called.

"Chess!" A hand landed on my shoulder and I jumped.

"Chill." Agent Thompson, my trainer here at the academy, told me. "I just wanted to let you know that you are needed tomorrow at Quantico at 1pm sharp."

"What?" I asked, confused. "Why?"

"Because there's a birthday party for you over there. Because the BAU wants you, brainless." He smiled at me. "I guess you didn't prove to be a total failure after all."

I looked at him, knowing that Thompson never means anything he says with a smile. He was harsh on me at first, but I grew on him and he grew on me. He learned that I will do anything to get what I want, and I learned that the insults are his way of pushing us over our limits into the wonders he believe we can do.

I wanted nothing more than to prove him I worth his trust, and I finally did.

"They do? What? Why?"

"Are you complaining?"

A smile jumped to my face. "Of course not! I just…" I hesitated. "What should I…"

"Say?" Thompson asked. "You'll figure something out."

I smiled mischievously. "I was going to say wear."

Thompson laughed. "Yeah, right." He said. "You'll wear what you always wear: Male cut jeans and shirt, one size too big. It's your hair you're gonna spend ages on."

"Hey!" I protested running my hand playfully through my pixie cut. "This doesn't look that good by itself."

"This doesn't look good, period." He replied. "I gotta go. Good luck tomorrow. Call me the minute you get an answer."

"Will do. Thank you so much for everything."

"Don't thank me yet." He warned and then smiled. "Thank me after you get the job tomorrow."

He ran away to one of the other agents and I was left there, feeling like I'm standing on the top of the world.

I entered the FBI building in Quantico, Virginia and walked towards the elevator, heart beating fast in my chest.

This is a job interview. I kept telling myself. Just a job interview. Either I pass it, or I don't. One way or another, there is nothing I can do but be the best I can.

I put the earplugs in my ears and pressed the play button on my mp3 player. "Eye of the Tiger" by Survivor started playing and I took comfort in the familiar tunes.

"It's the eye of the tiger,

It's the thrill of the fight.

Rising up to the challenge of our rival

And the last known survivor

Stalks his pray in the night,

And he's watching us all

With the eyeeeee of the tiger!"

I looked up and saw a blonde woman standing next to me and trying her hardest not to laugh.

"Did I sang it out loud?" I asked, embarrassed.

"Yes." She replied, biting her lip.

"How bad was it?"

She laughed. "Pretty bad."

"Sorry." I said, truly meaning it but a smile plastered on my face. "I just do that sometimes to distract myself."

The elevator stopped and I walked out. To my surprise, so did the woman.

"You're here for the interview?" She asked.

"Yeah." I answered. "Do you happen to know where's agent Hotchner's office?"

"It's over there." She said, pointing at one of the offices in what appeared to be a second level to the floor. "Good luck."

"Thanks." I said, the smile falling off my face and the fear filling me again.

Just a job interview. I repeated to myself. I can hunt a Vamp; I can get through a job interview.

I knocked on the door and heard a faint "Come in" before entering the room and closing the door behind me. The two agents from the day before were in the office. One of them sat in front of the table, and I guessed he was agent Hotchner. Guessed, because I blacked out entirely at that moment and couldn't remember my own name if I was asked. The other, agent Gideon, was lying on the couch, tossing a small ball into the air and landing in back into his fist.

"Sit down." Hotchner said, gesturing to the chair opposite to his and I walked ahead and sat, thanking God and anything that would listen I didn't fell down on my way.

"Agent-in-trainee Winchester –" Hotch begin but I cut him off.

"Chess." I said quickly and he looked up at me from what I assumed to be my file.

"It says Winchester." He said, his tone not entirely accusing but not entirely not. I had a feeling if I get the job, I will hear halves of tones a lot from him.

"It was when I joined the academy." I said. "Changed it. I don't use Winchester anymore."

"Why?" Gideon asked.

"Why don't I use my old name now that I changed it?" I asked.

"Why did you change it?"

"It didn't fit anymore." I replied. "I'm not a Winchester. I shouldn't use Winchester."

"Okay." Hotchner said, not entirely understanding. "Agent-in-trainee Chess, born January 24th, 1979, finished school at 18, and got accepted to Harvard shortly afterwards."

"Yes." I said.

"Why Harvard?"

"Why not?"

He looked at me. "Harvard is extremely expensive. You studied at a community high school in a small town at South Dakota. Why did you go to Harvard when you barely managed to pay your bills?"

"Because it was the only place where I could do a double degree in what I wanted to study." I replied.

"Linguistics and Religion." He read from the file. "Why those majors?"

"I knew many languages even before I went to Harvard, and wanted to use it for something, and Religion seemed like something interesting to learn."

"Are you coming from a religious home?" Hotchner asked.

"Quite the opposite, actually." I admitted.

"So you did it as an act of rebellion?"

"I did it because I wanted to." I said. "I was good at it and it turned out to be good for me, agent Hotchner. I'm not going to apologize for my choices."

"Fair enough." Hotchner said. "You have no record of family in your files. Are they deceased?"

"I'm not in contact with them anymore." I said. "Haven't spoken to them in seven years."

"Do you keep in contact with anybody from your life before Harvard?"

"Yes."

"Mind if I ask who?"

"An old friend from my teenage years." I said, biting back the smile that came from imagining what would be Ash's reaction to hearing that's how I phrased our relationship. We weren't dating anymore, but he was still more than just an old friend.

"This job is a very difficult one, agent Chess," Hotchner said, "I need to know you have a support system to help you."

"I do." I promised him and he nodded.

"Do you have any questions for us?" He asked.

I thought for a minute or so. "We were ten trainees at the last stage of the tests. All of us smart, all of us good, all of us qualified." I looked him in the eye, trying to trace lies in his answer. "Why me?"

"Why not?"

"I did nothing to attract your attention." I said. "At least not more than the others."

"Are you saying that we were wrong to pick you?" Hotchner asked.

"Don't get me wrong, I'm thrilled with this opportunity." I clarified, scared now that they might change their mind but in too deep to back off. "I just wonder why."

"What you said about Andrew." Hotchner said. "You told everyone to listen to what he has to say."

"So?"

"That was a major breakthrough in the case." Hotchner continued.

"So you should've gone with him." I said, even more confused. "Why me?"

"You didn't take credit for it." He finished and I looked at him, shocked.

"Why would I?" I asked. "He's the one who figured it out."

"If any of the others would be in your place, they would." Hotchner said.

"No, they wouldn't –"

"Yes, they would," Hotchner insisted. "You know it, we know it and they know it."

I shrugged. "What does it matters who figured it out? The important thing is that we did."

"Exactly."

"I don't understand." I said, frustrated. "What's your point?"

Hotchner leaned in and looked at me. "You get teamwork."

I stared at him. "Really?" I asked. "That's why you chose me? I get teamwork?"

"Our team is like a family." Hotchner said. "We get each other. We help each other. I needed someone who gets that dynamic in order to fit in and you seemed like the best choice."

"But why?"

"Why do you want to be in the BAU?" Gideon asked.

I turned to look at him. "Because you do an incredible job. You're saving people, you stop the bad guys."

"Everybody in the FBI do that. Why us?"

"Because serial killers don't stop until they're stopped." I said simply. "The people you put in jail, how many more would they kill if you didn't stop them? How many lives have you saved, without them knowing they are safe? People who can have lives, families, people around them, because of you."

"There." Gideon said. "You don't look for rewards. Saving people, stopping the murderers, that's your reward. That's why you don't mind the credit."

"You want to be in the BAU for all the right reasons." Hotchner added. "That's why we chose you and that's why I'm glad we did. Would you like to start today?"

"I… what?" I nearly didn't comprehend what he was saying. "I mean, yes! Yes, of course!"

"Alright." Hotchner's face shifted into something resembling a smile. "We have about thirty minutes to finish the paperwork before out Technical Analyst, Garcia, will detail us for our next case."

"You… you really want me?" I asked.

"Is it really that hard to believe?"

"Yes. I mean, no. I don't know." My face lit up with a smile. "Thank you."

"You're welcome." Gideon said and I turned and smiled at him. "I'll be going now." He said. "Paperwork's not really my thing."

Hotchner nodded at him and Gideon left the room. He then turned to look at me.

"SSA Diana Chess, welcome to the BAU."

Well, there it is, Chapter one... R&R!
