Dexter: Season 3, Episode 8

3 - 8: The Damage a Man Can Do

Miguel finds Dexter another victim, a debt enforcer called Billy Fleeter (Jeff Chase), whom Miguel wishes to kill. Debra discovers that The Skinner is a tree-trimmer and learns that Anton was never registered as an informant. When she tells him that he was never legally obliged to work for the police, he disappears. Rita loses control due to her pregnancy hormones and is angry at Dexter's refusal to help organize their wedding. After Ellen expresses her concern about Miguel's behavior towards LaGuerta, he makes an unannounced visit to her house and presumably kills her.
