Dean (Jensen Ackles) and Sam (Jared Padalecki) are going on to a new mission in the upcoming new episode of "Supernatural" Season 12. The new case will make Mary Winchester's (Samantha Smith) path cross with her two sons.

According to Parent Herald, "Supernatural" Season 12 Episode 6 will feature the supernatural hunters trying to find a demon that starts picking off the other hunters one by one. Sam and Dean will try to investigate before this Demon does any harm to them. Mary is said to help her sons in this mission.

In a promotional photo for "Supernatural" Season 12 Episode 6, Mary can be seen with a new look along with her two sons. She also meets Sheriff Jody Mills (Kim Rhodes). Jody served as Sam and Dean's mother figure while she was away, so it would be interesting how this first meeting would go between them.

Meanwhile, GameNGuide reported that "Pretty Little Lars" star Kara Royster will join the cast for "Supernatural" Season 12 Episode 6. It was said that she will portray the role of Alicia who is a supernatural hunter that was raised by a witch. It was reported that Alicia will meet Sam and Dean in Episode 6 during the gathering of Asa's death.

Aside from that, "Supernatural" Season 12 Episode 6 will mark the return of the Grim Reaper Billie (Lisa Berry). In a promotional clip for the episode, the hunters seem to be trapped inside a house. She tells Dean the rules of the house and one of those is that it's a one-way ticket.

Does this mean that all the hunters trapped inside will die? Dean is expected to fight his way out of the situation.

Another interesting episode is to be expected in "Supernatural" Season 12. Episode 7 titled "Celebrating the Life of Asa Fox" will air on The CW on Nov. 17.
