Sam (Jared Padalecki) and Dean (Jensen Ackles) will be on a mission to stop Hitler from coming back to life once more. Meanwhile, the British Men of Letters are killing Lucifer's special children.
Previously in "Supernatural" season 8, a Nazi group with supernatural abilities called the Thule Society tried to bring Hitler back to life. But Sam and Dean were able to prevent this from happening, with the help of a member of the Judah Initiative named Aaron Bass (Adam Rose).
In the upcoming fifth episode of season 12 — titled "The One You've Been Waiting For" — the Winchesters will embark on the same mission again. According to the synopsis released by Spoiler TV, "After learning that the soul of Adolf Hitler has been trapped in a 1930's gold pocket watch, Sam and Dean must act quickly to prevent a group of Nazi necromancers from resurrecting the Führer."
In the episode 5 trailer, the 1930's gold pocket watch appears to make people who have hold of it murderous, and Dean will even resort to using his grenade launcher.
Meanwhile, it seems that the British Men of Letters are taking down the special children of Lucifer.
Previously in "Supernatural" season 12 episode 4 — titled "American Nightmare" — a psychic named Magda (Paloma Kwiatkowski) was saved by Sam and Dean from killing more people, including her own mother. However, in the end, Magda was killed by the British Men of Letters despite having redeemed herself.
According to BuddyTV, the British Men of Letters killed off Magda because they have a way of eliminating anything and everything that could become a threat to the world's safety. Magda was a threat because she was revealed to be one of Lucifer's special children, and with Lucifer out and free in the body of Vince Vicente (Rick Springfield), he might summon his special children and start something that might end the world.
"Supernatural" season 12 airs every Thursday at 9 p.m. EST on The CW.
