Ephraim met Castiel several years ago. He envied Castiel's fame and power, and admitted he knew Castiel failed more often than he succeeded but he always went big. He also never came to Earth before the Fall and had never had a vessel before.
After falling to Earth, Ephraim gained a vessel in the form of a man who had recently become deeply religious and a follower of the Reverend Buddy Boyle. Not understanding the ebb and flow of human pain due to his lack of interaction with humanity, Ephraim began a crusade to rid the world of pain by smiting those who were in pain. His vessel's wife was his first victim and he went on to kill four more people, drawing the attention of Castiel and Dean Winchester. While most of these people were suicidal or in bad emotional states, Ephraim also killed a girl who was simply upset over a bad breakup with her boyfriend. Ephraim eventually tracked Castiel's deep pain to a house where he was babysitting and confronted him. Castiel thought he was there for his manager Nora's baby, Tanya, as she was sick and crying, but Ephraim wasn't: he was there for Castiel's pain. After trying to reason with Ephraim, Castiel attempted to banish him but failed. Ephraim confronted him to tell him that he should be trying to help the angels get back into Heaven and prepared to smite him. He felt that by remaining human, Castiel had already given up. Dean, who had figured out what Ephraim was up to, arrived and tried to stop him, but failed and Ephraim began to smite Castiel. However, Dean slid Castiel an angel blade and he killed the misguided angel with it. The encounter left Castiel disturbed as he realized Ephraim was right about how he should be helping the angels.
