Mary Winchester

Mary Winchester 'nee Campbell was the wife of John Winchester as well as the mother of Sam and Dean. She was killed by Azazel in 1983 for failing to keep a promise she had made to him ten years previously. She was born sometime in 1954 and raised in the hunter lifestyle, a lifestyle that, much like her youngest son Sam, came to detest and rebel against it. She vowed that she would never raise her children in the life she was raised in. Sometime before 1973, she met John Winchester in Lawrence, Kansas. At first, the two hated each other, and due to Heaven's intervention, the two eventually resolved their differences and fell in love. Mary was happy, to her, John represented normalcy. She craved normal and recognized that she could have that with John.

She warred with her family over her decision to be with John. Her father, Samuel, was openly disapproving of John Winchester and had no trouble expressing those opinions. The night she finally decided to ask John to propose to her, the Yellow-Eyed demon came in, possessed her father (both of her parents were dead, killed by him), and just when John was about to propose to her, Azazel showed up, ripped John out of the car and killed him. She begged him to make things right, to save John--he agreed. On the condition that she let him inside her home in ten years, he would bring him back to life. She agreed and John was brought back. The two later married.

In an alternate reality created by a djinn and a reality that Adam was forced into, Mary, though still dead, was dead not because of a demonic attack but because of a electrical shortage that caused the fire in Sam's nursery.
