Mary Winchester

Mary Winchester is a fictional character created by Eric Kripke for The CW television series Supernatural. She was portrayed by Samantha Smith.

Biography
Mary Winchester (born 1954) is the wife of John Winchester, and mother of Sam and Dean. She gave birth to Dean on January 24 1979 and Sam on May 2 1983.

In the episode "Children Shouldn't Play With Dead Things" Dean refers to an uncle they have never met. It is revealed in "The Kids Are Alright" that Mary's uncle is dead.

In the episode "Pilot," it is revealed that on November 2 1983, Mary woke after putting her six-month-old son, Sam, to bed. She entered his nursery to find someone she thought to be John leaning over his crib. Returning to bed, she noticed a television flickering downstairs. She found her husband John asleep in the living room, and ran back to Sam's nursery. Hearing his wife's screams, John ran into the nursery. In Sam's room, everything appeared normal, until he saw droplets of blood next to Sam's head. Looking up, he found Mary pinned to the ceiling with a large gash through her stomach. She then burst into flames, dying at the age of 29. She was murdered by "The Demon," the series' villain.

In 2005, her sons returned to their childhood home to investigate a recurring dream Sam had experienced in the episode "Home." Mary's spirit seemed to haunt the house in Lawrence, Kansas where she died, and a powerful poltergeist was in the house with her, though the psychic Missouri Moseley never felt their presence. After the poltergeist pinned Sam to the wall, Mary appeared in the room that was Sam's nursery as a flaming figure. When Dean broke through the locked door to reach him, Mary told Sam that she was sorry. Sam asked why she was sorry, but she turned to the ceiling, and told the poltergeist to leave her sons alone. Her spirit sacrifices herself in order to banish the poltergeist, forcing both spirits out of the home.

"What Is and What Should Never Be", it is Mary's birthday and the date is December 5th.

"All Hell Breaks Loose - Part 1", the Yellow-Eyed Demon shows Sam a vision of the night Mary was killed because she was in the wrong place at the wrong time. It is revealed that she was killed because she interrupted him as he fed his blood to baby Sam. When Mary ran back into the nursery, she recognized him when she said "It's You!" to the Demon. At this point of the series, it remains unclear how she could have known the Demon. Though, in Supernatural: Origins, it seems that Mary has a sister that the Demon was apparently after, but this is unconfirmed.

In "The Kids are Alright" we learn that all of Mary's friends and acquaintances have been killed off over the years since her death.

In "In The Beginning", it is revealed that Mary was a hunter who knew a lot about the Supernatural Universe. She made a deal with the Yellow-Eyed Demon in 1973 to revive her boyfriend John Winchester, which allowed him to bleed into Sam all those years later. He also told her that all long as nobody interrupts him, they wouldn't get hurt. She was killed by Azazel for not fulfilling her promise.
