1x12 Faith

While battling a Rawhead, Dean gets electrocuted and his heart is damaged. Doctors give him only a few weeks to live. Sam searches for a way to save him and believes he may have found an answer in a preacher who claims to heal the incurable (Kevin McNulty). At the congregation, Dean is chosen, and is cured of his condition. However, he and Sam soon learn that an openly gay teacher died of a heart attack at the same moment that Dean was healed. Further research reveals that deaths occurred in unison with other healings, prompting the brothers to believe that the preacher is using black magic to control a Reaper; healing people in exchange for the lives of those he deems immoral. However, they eventually discover that his wife (Rebecca Jenkins) is behind everything, and rush to destroy the altar used to control the Reaper. The preacher begins to "heal" Layla (Julie Benz), a young woman with a brain tumor, and the Reaper then goes after Dean. Sam destroys the altar, and the freed Reaper takes the wife's life, though the young woman is not healed. She later tells Dean that she has made peace with her coming death, and Dean promises to pray for her.
