S1·E5 In Mysterious Ways

Nick temporarily transfers to civil court, where he hears a case against the televangelist Horace Blake, who has made a Bakker-esque claim that the Lord will take him on Easter if he does not raise a certain amount of money. The Watchmen set out to convince the reverend that the Lord is fully intending to bring him home, in other words, to con a con man into believing his own scam.

Cat plays a prostitute to test Blake's faith, Gibs is the new sound guy on the TV show, who then introduces the plagues to his viewers. A burning bible, frogs, the mark of the devil, all this tests Blake's scam in his own mind. In a deranged panic, he kidnaps Cat and takes her to the apartment where his father, also a preacher, died of a heart attack with a prostitute. Eventually, Blake confesses all on TV, gives the money to the masses, and eventually preaches to his fellow prisoners.
