Paint It Black

S10 E16: Sam and Dean investigate a string of suicides committed by people with little in common other than the identical, grisly method of death – slow, self-administered disembowelment. All of the victims were members of a Catholic church and had recently given confession, leading the brothers to suspect the priest (guest star STEPHEN DANIEL CURTIS) is somehow involved. Meanwhile, when Crowley captures Olivette (guest star TERYL ROTHERY), the leader of the Grand Coven, Rowena pleads her case to be allowed to practice magic freely again.
