The Season 11 finale saw the resurrection of Sam and Dean's mother Mary Winchester. In the final moment of episode 23 "Alpha and Omega," Dean is reunited with his mother. However, Sam is yet to find out that his mother is back. At the same time, Lady Antonia Bevell of the London Chapter of the Men of Letters brought bad news to Sam that Men of Letters are coming after him for punishment for his actions.

"Supernatural" Season 12 is expected to explore the storyline involving Men of Letters and Sam and Dean's battle against them. They are clearly the new threat to the Winchester brothers and they are unlike any other challenge they have ever tackled.

Meanwhile, Mary's return is expected to have a big impact on the brothers' lives as hunters. According to Buddy TV, Mary's death is the reason behind what Sam and Dean are to this day. Her resurrection is expected to "change everything."

"Supernatural" Season 12 episode 1 is expected to reveal what happens after Lady Antonio fires gunshot at Sam. It can be assumed that Sam will not die. However, the arrival of the Men of Letters will threaten their wellbeing.

According to the website, the show has been trying to build up Men of Letters storyline since a long time. And finally, it will come into play. It is speculated that with Men of Letters arrival, the show may see Sam and Dean become the rogue agents.

The main storyline of Season 12 will not see the Winchester brothers fight monsters and stop mysterious creatures from destroying the world. Instead, they will be up against Men of Letters, who know all about them and the supernatural world.

In addition, fans can expect to see some changes in "Supernatural" Season 12 as the showrunner Jeremy Carver has been replaced by Robert Singer and Andrew Dabb. Nonetheless, the duo has enough experience with "Supernatural" team. Singer has been on the team since Season 1. As for Dabb, he joined the writing team in Season 4. Several media outlets are expecting a change in the format of the series with the main antagonist being Men of Letters.

More changes include the change in time slot. According to Deadline, "Supernatural" Season 12 will air on Thursdays on The CW after "DC's Legends of Tomorrow." However, the network is yet to announce the premiere date. Considering the previous seasons' schedules, episode 1 is expected to air in the first week of October 2016.
