We all know that Mary Winchester was murdered by a demon in 1983. But what if she wasn't just a normal everyday housewife. What if she had been a slayer and had died only to be revived by her watcher, and then able to leave the Council's control and create her own life.

When she was 22, four and half years after leaving the council and letting them think she was dead, Mary meets John Winchester. They were married a year later and have their two children Dean and Sam. When Mary dies in Sam's nursery on November 2nd, 1983, the PtB give her a proposition and her spirit was then sent back in time to January 18th, 1981 and reborn as Buffy Summers. Twenty-five years after her rebirth as Buffy, it's time for her to return home to her husband and sons.
