The Winchester brothers need a bit of a breather following Dean's (Jensen Ackles) showdown with Cain, and "Paint It Black" will mark the second episode in a row of good, old fashioned hunting for the boys.

Catholic parishioners are slowly disemboweling themselves in episode 16, urged by some invisible force to commit a slow and brutal suicide. Each of the victims recently made a visit to their local church for reconciliation, and a priest (Stephen Daniel Curtis) will quickly top the Winchesters' suspect list.

Meanwhile, Rowena (Ruth Connell) will move forward with their plans to get the Grand Coven of her back. With a little aid from the King of Hell, aka her wee boy Crowley (Mark Sheppard), the witch will have a little chit chat with the leader of the Grand Coven (guest star Teryl Rothery).

Will Dean continue to itch under the influence of the Mark? The elder hunter claimed he was just dandy after taking down the Father of Murder, but Sam (Jared Padalecki) knows that's not true. Find out how fighting Khan worms in "The Things They Carried" and dealing with this new holy terror in "Paint It Black" will affect the brothers when Supernatural returns to The CW on March 18 at 9 p.m. ET.
