Rita threatens to leave Dexter if he does not commit to a program to deal with his drug addiction. He starts attending Narcotics Anonymous meetings, while still trying to evade Doakes' constant surveillance. At the meeting, Dexter meets a mysterious and flirtatious woman named Lila (Jaime Murray), who volunteers to be his sponsor. Doakes tracks Dexter at the meeting, but to Dexter's relief, Doakes displays understanding of the "addiction" and lets Dexter go. Later, he hunts down a new victim, Roger Hicks (Don McManus), a used-car salesman who murders beautiful brunettes. Lundy invites Debra to join the new task force investigating the Bay Harbor Butcher, and soon discovers a pattern to the murders.
After being "all Jekyll and no Hyde" for a long time, Dexter has regained his lethal touch and quickly finds his old way of killing the ones that got away. I think the soul of the series returns in this episode, as Dexter returns to old habits. I think it is good scriptwriting that he still has to look out for the FBI agent and handle Doakes, who's still on his tail. This keeps the tension up.
Debra finds herself surprisingly included in Agent Lundy's special task force assigned to hunting the "Bay Harbour Butcher" (Dexter), and the thought of having his own sister hunting him disturbs him. At the same time, she has to continue facing her own demons, and I like the way that the storyline is progressing there. Keith Carradine does a nice job portraying Agent Lundy, playing it straight and doing it well and with the weight required for the part. He's definitely one of the better recurring characters, and helps Debra find her way.
Following the serious tone of the two first episodes of the season, this episode lightens up a bit. The black humour is back, and Vince Masuka gets a little more screen time, and he's hilarious as always, I like that.
A major theme of this episode is Dexter's way of handling his addiction to murder, and that he actually can use his visits to the alcohol rehabilitation group in a good way.
