Cas had always said that Dean was the reason he first came to Earth. He said that he had never stepped foot on this soil prior to Dean. Of course he would never lie to Dean, but he could always withhold the truth.

Cas had recently moved into Dean's room and the couple couldn't have been happier. Although the angel didn't sleep, Dean always enjoyed his presence. Sadly his lover tended to leave a mess behind him. The angel wasn't used to having to look after himself so Dean left it up to himself.

The hunter was finishing up laundry when he found it. Under his boyfriend's back-up trench coat, he found an old leather bound book. The couple didn't have secrets so Dean didn't feel like he was invading any privacy when he opened the book.

Inside were dozens of pictures, pictures of a young couple on each page. What surprised him the most was that one half of the couple look slightly similar to himself. The other half of the couple was always changing; it could be a blonde woman or a black haired man. It was always obvious that they were in love in some way, as best friends or something more.

They would gaze into the other's eyes or have their arms wrapped around the other tightly. Dean was so enchanted with their love that he almost forgot the problem at hand. Why did his boyfriend have these pictures of doppelganger Dean?

It wasn't until 20 minutes later that Dean was able to look away and that was only because Castiel walked into the room.

"What are you doing?" Cas asked in a wary voice. "How did you find that?"

"Shouldn't I be the one asking questions?" Dean didn't mean to sound angry, but their relationship had always been honest and here was Castiel keeping a secret far too huge. "Who are they?"

"Isn't it obvious?" His voice suddenly became soft and his eyes contained so much vulnerability.

The confusion in Dean's eyes must have answered the angel's question because he gave the answer that Dean didn't want to hear. "It's us."

Dean only stared at the man he was in love with. He knew he wasn't lying, all he had to do was look into his honest blue eyes. But how could this be? And why would Castiel even leave evidence of it?

"I have been sworn to protect you since my father first created me. The legend of Michael's sword was never set at a certain time. Once God disappeared and Metatron had run away, no one knew when the battle would take place. We only knew of the vessel and this particular vessel would recreate itself until the legend was fulfilled. You are Michael's sword and you will continue to reincarnate yourself because you avoided that destiny."

Castiel sat next to Dean on the floor and gently removed the book from Dean's lap. He pointed to the painting of two men in red coat uniforms One looked like Dean, but the other had red hair and brown eyes. "We were serving the British army against the Americans and the revolution. You died when George Washington sailed for the Delaware River. I had failed my mission then."

Cas turned a few more pages, but stopped at a picture in black and white. Dean was smiling with his arm around who he assumed was Cas, only it was a brunette girl. "We had just sailed to America from Germany. We lived in the North and you died of old age. I didn't fail my mission, but we were still waiting."

He turned to another picture, but he smiled fondly at this one. The blond man with blue eyes was kissing Dean on the cheek. "This is the first one of us as a "gay" couple. It was in the 1960's and Stonewall had just been unrightfully raided. We were marching for equality and later that day someone shot you. I failed my mission and they told me if I failed again I wouldn't be able to see you anymore."

The angel turned to the last page and this picture was by far his favorite. It was the current Dean from 1 year prior and Dean had just asked him to be his boyfriend. "This is the day after you asked me on our first date. Sam had taken it jokingly, but it's always been my favorite. I didn't fail my mission because you didn't agree with your destiny."

Castiel looked at Dean for the first time then. He looked into those green eyes that he had known for centuries and still felt the same love he always had. Dean always the same. He was rough around the edges, but he would always take care of you. When they fought in wars together, Castiel was always first on Dean's mind. When they had trouble assimilating to life in America, Dean ignored the racial slurs directed at him but wouldn't stand for it when they were directed at Cas.

"You will always be my favorite Dean. You were able to change our fate, you were able to make us more real than any of the others. I've wanted you to know that I have always loved you in each lifetime. I wanted you to remember us; I wanted you to remember our first time in America and our first night on a battle camp. But I guess it didn't matter because in each life you loved me just as much as I loved you."

Dean was trying not to let the tears spill from his eyes, but he was finding it hard when Cas was expressing himself so freely. Of course they knew how strong their feelings were for each other, but because of Dean being the way he was they never really spoke of it.

Cas continued talking, ignoring the unusual silence from his boyfriend. "I wanted to tell you, but I didn't know how and if you're angry with me I understand."

Dean stared at the book once again and carefully took it back from Cas. He gently closed it before grabbing Cas into a hug. Cas buried his face into Dean's neck so glad that he was able to understand. Dean had his fingers tangled in Cas's wild hair and tears slipped into the ebony strands.

The hunter placed gentle kisses on the crown of his love's head because he couldn't express into words how much he loved him. He had never been good with words and it had been obvious his whole life. He believed actions were louder than words and that was the only way he could truly and unleash his feelings.

Dean spoke anyways trying to be the man his angel deserved. "I will always love you and it seems that I always have. And if what you're say is true I will love you to the end of time. When this body fails me, I know the next one will be just as capable of loving you. I hope I'm not too difficult because we both know I can't live without you."

Dean kept his promise. After he died years later from a freak hunting accident, Cas spent his time looking for the man again. He found him in a museum, bored out of his mind but staying for the sake of his younger sibling. So Dean. Cas still had the same old vessel, so he would have to wait a few more year to meet the teen.

On his 27th birthday, Dean went to a bar and saw a man in a trench coat, nursing a whiskey. He knew right away that he had to speak to him, there was something about him that Dean didn't want to miss.

"Hi, I'm Dean."

"Hello, Dean."
