Fantasy horror television series 'Supernatural' is going to be a lot more interesting as Mary Winchester's secret past is going to come out. Speculation is circulating among fans about how Sam and Dean are going to proceed after encountering their newly revived mother's past.
"The story's always been 'Once Mary married John and settled down, she stopped hunting," said showrunner Andrew Dabb.
"But we're going to find out maybe that's not the whole story," he added, teasing a huge revelation.
Mary was killed by the demon Azazel six months after Sam was born but when Dean reunited God and the Darkness after 33 years then she was resurrected by God for Dean.
The twelfth season will premiere on October 13, 2016, and will consist of 23 episodes that will air on Thursdays.
Mary, in the upcoming episodes, will be terrified by her abrupt and raging death.
Her two screen sons Sam Winchester played by Jared Padalecki and Dean Winchester by Jensen Ackles discussed their mum's return.
"The adjustment is going to be very tricky," said Ackles while terming Mary a "stranger."
Padalecki argued that hunting is in Mary's lineage and her sons have adapted to that and they are good at it. Reacting to Sam's wish of not letting his mother hunt he added, "It's my mom, man. I don't want to see her get punched or shot or bit by a vampire.
The series follows the story of two brothers hunting demons, ghosts, monsters, and other supernatural beings in the world.
