Ep 14. The Raid

In Supernatural season 12 episode 14, titled "The Raid," Sam and Dean Winchester continue to search for the missing ingredients to create the weapon that can defeat the British Men of Letters. With only one ingredient left to find, the brothers receive an unexpected tip from a supernatural creature that leads them to a black market for rare artifacts.

As the brothers prepare for the heist, they enlist the help of two familiar faces: Felix (the demon who they previously worked with to stop the Darkness) and Crowley (the King of Hell himself). With the clock ticking, the group infiltrates the black market and must navigate through dangerous obstacles and supernatural creatures to secure the rare item they need.

Meanwhile, Mary Winchester, still grappling with her return from the dead, receives an unexpected visit from Ketch, a member of the British Men of Letters. Ketch offers Mary a deal: if she agrees to work with the British Men of Letters and report back to them on the activities of the Winchester brothers, they will help her find a way to cope with her newfound life.

As Mary struggles with the decision, Sam and Dean successfully retrieve the ingredient they need and return to the bunker to complete the weapon. However, their victory is short-lived as they discover that the British Men of Letters have already infiltrated their home and are searching for the brothers.

The episode ends with a tense standoff between the Winchesters and Ketch, setting up a new dynamic in the ongoing conflict between the two groups. "The Raid" is an action-packed episode filled with suspense, surprising twists, and the continuation of the season's overarching storyline.
