how did rita's husband die in dexter
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 can't fully explain how he knew to stage convincing evidence that the man was using heroin. Rita incorrectly concludes that Dexter is, like Paul, a drug addict and that this explains his occasional absences and odd behavior. Dexter decides to falsely admit that this is the case 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.
