November 2, 1983

November 2, 1983 is the night that Azazel enters the nursery of six month old, Sam Winchester and feeds him demon blood, making him one of his "special" children. Unknown to many of the players until years later, the demon had arranged to be there ten years previously when he saved John Winchester from death and made a deal with his then-girlfriend, Mary Campbell. Now, ten years later, Azazel enters Mary and John's home and fulfills his part of the deal. Mary is asleep when he enters, but awakes when she hears sounds coming from the baby monitor. She gets up to ask John if he's hungry, but recieves no answer. Content, she starts to go back to bed only to notice the flickering lights from the TV downstairs. When she arrives on the landing, she notices, to her horror, that the person in the room was not John whom she assumed it to be at first, but rather the demon, as referenced when she says, "it's you." The demon, angry at being interrupted, slams Mary against the wall, creats a large gash in her stomach and pins her to the ceiling of the nursery. She lets out a blood-curdling scream that instantly awakes John, he scrambles up the stairs, throwing open the door to Sam's nursery, only to find nothing apparently wrong. He relaxes some until he notices faint blood drops appearing near Sam's head and on his hand. He is confused until he sees: Mary pinned on the ceiling. He falls backward in shock and watches with horror as the ceiling explodes into a fiery inferno. He grabs Sam from his crib and tells Dean to take him outside as fast as he could and "don't look back". Dean races Sam outside while John tries desperately to get Mary out, but it's too late.

This night and the death of Mary, is the event that pushes John into the life of a hunter. He gets the answers that he seeks when he visits Missouri Mosley, a psychic in Lawrence who tells him about the supernatural. After that, John and the boys embark on a quest to find and kill the thing that killed Mary. For many years, the night was shrouded in mystery until Azazel reveals to Sam that the reason that Mary had died was because she had interrupted him while he was feeding Sam the blood and that ten years previously she had agreed to let him into her home and not interrupt him.
