A/N: My first attempt at a multi-chapter Supernatural fic, so bear with me a little. I know this has been done before, so I hope my story is at least a little original. Let me know what you think, whether you want me to continue, etc.
Summary: AU. Sam and Dean were both adopted by different families when John turned out unfit to raise his children due to alcohol abuse after Mary died. Sam's family moved to England, while Dean stayed in the US.
Prologue
"NO, no Daddy please!" Six year old Dean was fighting the social worker who was trying to take him away from his family with all of the force he could muster up, but it was useless. His father watched helplessly as they took his two children away, the only things left in Mary's memory. He tried to fight it, he tried with all his might, but it was a lost case and now he was doomed to watch his children be taken away.
Little Sammy was crying, his arms stretched out, hoping to cling onto Dean. The despair written onto the little boy's face was heartbreaking and reduced John to tears.
"Daddy, please, don't let them take us!" Dean whispered and looked at his father expectantly. Maybe now, Daddy would be the superhero he always was when he was fighting monsters, too, and grab them and run away with them so they wouldn't have to leave. John shakily sat down onto the nearest chair and tried to blink away the tears so they didn't blur his vision. He didn't want the last memory of his sons to be blurred. Dean's arms and legs went limp when he realized Daddy wasn't going to come and save them, and he looked at John with such a hurt look across his face, and it broke his heart – he wondered if it was still possible to break, seeing as it was in tiny pieces already. Though, how much it might hurt, John knew what a horrible father he'd become and that this would somehow turn out for the better for his children because they were going to families that would take better care of them than he ever could.
