Dexter (season 2)
Rita doubts Dexter's reliability and honesty after finding evidence that he set up her husband Paul to be returned to prison. After her husband dies in a prison fight, Rita confronts Dexter with her suspicions. He admits to setting up Paul but after claiming it was a spontaneous act, cannot explain why he happened to be carrying heroin. Rita incorrectly concludes that Dexter is, like Paul, a drug addict and that this explains his occasional absences and odd behavior. Dexter admits that he does indeed have an addition (without specifying what that addition is) and promises to seek help by joining Narcotics Anonymous. There, he meets Lila Tournay, who offers to be his sponsor. Sgt. James Doakes remains suspicious of Dexter's true motives, and constantly monitors Dexter's whereabouts.
