Disclaimer: I don't own Harry Potter or Supernatural which make me sad because I could put Dean Winchester to some good use.

Authors note: This is my first published fanfiction so please bear with me. I would love to hear all suggestions and comments and thank you all so much for reading!

THEN:

Eleven years ago everything was different for the Winchesters. It was the end of the wizarding war and in fact Mary had just returned from partaking in the battle at Hogwarts. John, being a muggle had not gone along but waited for agonizing hours with his sons to find out if she was okay. Finally she returned home to the security of her family. They were a happy little family; John worked in a mechanic shop and hunted rouge creatures and the darker supernatural beings while Mary stayed home with her beloved sons on her maternity leave from the ministry of magic. This pristine little lifestyle only lasted a few months. On November second everything changed for this small family.

Mary woke up to the noise of Sam fussing in his crib. She rolled over and reluctantly left the warmth of her bed and began down the hall to Sam's room. At first it seemed that John as already tending to Sam, then he turned around. His eyes glowed yellow in the darkness as he gave Mary a crooked smile. "Hello Love, you remember me don't you?" Mary gasped as the man reached a hand into the crib. "You get away from him…Now" She stated firmly as she shifted her wand in her hand. "Oh Mary, don't be so off-putting we both know you took my son's life that night at Hogwarts and now it's my turn to take something from you" He said simply while picking Sam up and cradling him in his arm. He turned to look at Mary and saw the horrified look on her face. "Don't worry I wont kill him but I need someone to take the place of my son" The werewolf dragged a fingernail across Sam's arm creating a cut. The clouds are clearing up so as soon as I go outside I can wolf out and finish the job" He explained casually leaning against the crib. "You mangy bastard" Mary spat and just as he opened his mouth to reply she threw a well aimed spell at his head while at the same time managing to avoid Sammy. He was quick and expertly dodged it as it the wall behind him making a crash.

Realizing Mary was not going to wait for him to make the first move, the werewolf hurled himself out the window and dropped to the yard below never even disturbing the baby in his arms. Mary apparated outside directly in front of the man who was at the very moment, undergoing a transformation. His claws extended and scratched along her youngest sons back creating three gashes in his fragile frame. "My baby!" She cried out in desperation to save her son. She sent another spell at the predator and this one sent a slice into his cheek. He growled directing his attention back to her and sprung into attack.

At this point John had woken up and was frantically searching the house for the missing half of the family. Dean was hot on his trails calling out for his mother and baby brother. John went back into Sammy's room to look once more when he saw the opened window "Dean, stay in the house!" He ordered as he ran down the stairs and out into the night with only a shotgun to protect him. John rounded the corner of the house just in time to see his loving wife have her stomach ripped open by a werewolf. The monster seemed injured and weakened but John didn't have the right bullets to actually kill him so he would just have to make that animal hurt. "Hey you son of a bitch!" He bellowed at the werewolf that was now moving towards the woods for cover. He shot several rounds wounding it further but it only turned around once showing John its terrible yellow eyes then it disappeared into the darkness of the woods.

John Ran to his offended wife who was bleeding badly and gasping for breath. "Mary, oh God Mary what do I do?" He asked desperately as tears clouded his vision. "Sa-Sammy over there" she breathed out struggling to stay coherent long enough to tell John what he needed to hear. "Contact the ministry…" She gasped for air "My journal in the old trunk…Love you, Dean, Sammy" They both knew she didn't have much longer, that's when Dean arrived beside them looking frantic and terror-stricken. "Dean go get your brother NOW. You need to take care of him" John ordered. Dean moved fast and rushed back to his mother's side. "Mommy?" he asked worried while he rocked Sam. Mary sobbed and smiled at her beautiful boys "Mommy loves you, Sammy and Daddy very much, Dean remember that always" Dean began to cry "I'll always love you mommy" And with those words filling her ears Mary took her last breath.

John sent Mary's owl to the ministry describing exactly what happened and the next day they sent two agents to the house. They advised John about Sam's injuries and how they would affect him throughout his life. Because they were only scratches Sam would never be a full werewolf but certain measures will have to be taken to make sure he would not be a danger to himself or others. Dean got into the habit of not talking much, he also became very protective of his little brother. John decided that the rest of his life would be dedicated to finding and killing that yellow eyed bastard and he would not let his sons grow up without training the to protect themselves.

To say the least things changed. Dean became the main guardian of Sam while their father was preoccupied with hunts and they began training as soon as they were old enough. They traveled often, going on hunts but they still kept their home so the boys could have something consistent in their lives. John had listened to Mary's words and discovered a journal she had written in the chance that she would be killed in the battle at Hogwarts. This journal would help in his journey of raising two wizards. This was the beginning of an entirely different world.

Okay how did I do guys? This chapter is kind of just to explain how everything was started and how things will go. Like I said I would love to hear from you guys so review please!
