Castiel will get in a deadly situation in "Supernatural" season 12, episode 12. Spoilers reveal that the Winchester brothers plus Castiel will get themselves a new case courtesy of Mary. However, Mary will neglect to mention the most important detail -- the British Men of Letters are involved!
"Supernatural" season 12, episode 11 was full of laughs with Dean's memory loss. It was funny how he was mistaken for a homeless man as well as those moments as he rediscovers himself and his love for Scooby Doo. And of course, that epic moment of him riding a mechanical bull at the last part. A memory-less Dean saved the day killing the Loughlins while Rowena broke his curse using the Black Grimoire.
Sam, Dean, and Castiel are getting a new case in "Supernatural" season 12, episode 12. The official synopsis via Spoiler TV reveals Mary (guest star Samantha Smith) will ask the three for help in a case she is currently working on. However, she will fail to mention the involvement of the British Men of Letters. Isn't that the first thing she should have told them?
The British Men of Letters has been keeping tabs on Sam and Dean. In a previous interview with TV Line, "Supernatural" executive producer Andrew Dabb said they are going to be a threat to the Winchesters in season 12. "They're a threat," he said. "Going into this season, it's a dual-pronged approach. [Dean and Sam are] pulled in two different directions."
Mary would be betrayed and the three will discover the connection of the British Men of Letters in the case. However, Mary's action will put Castiel in danger. The teaser for "Supernatural" season 12, episode 12 shows Castiel literally crawling for his life. "Please... don't make my last moments be spent watching you die. Just run!" he told Sam and Dean.
"Supernatural" season 12, episode 12 titled "Stuck in the Middle (With You)" will air on Thursday, Feb, 16 at 8 p.m. EST on The CW.
