A vision leads Zed and John to a small town with an unusual preacher on Constantine. "Blessed Are the Damned" is the seventh episode of the show's first season.
Constantine: You said snakes? Zed: Yeah Constantine: Our training is expanding your psychic awareness. You see there. Zed: What Kentucky? Constantine: Middle of bugger all. Seems a preacher was bit by a poisonous snake which explains your vision. He came back to life and started performing miracles. Now he's a bloody star.
Zed: I could feel him John. He was so close to death. I felt what he felt in that moment. Constantine: An angel so you said. So you get any other sense of Zachary the great and powerful? Zed: Well, he has good intentions and he's unquestioning in his faith. Constantine: A bit boring, but okay. Let's say he's not the dark part of this equation. Zed: Unless he's being manipulated. Blind faith can be a dangerous thing. Constantine: Spoken from experience.
