Excellent episode with some character development.
I loved Debra's storyline. The way she got back together the with guy from the gym, the way she handcuffed him to the bed especially was a clear demonstration of the effects Rudy had and still has on her. I do think she's making progress, especially after she suggested a readl date, I was afraid she was going to cut him off, but she didn't so good for Debra.
Dexcter now lives in constant fear of being discovered as the Bay Harbor Butcher, even though the 'Butcher' is turned into a hero by the end of the episodes when the police publicise that he only killed bad people.
I loved how Dexter changed his mind about Rita mom depending on the comments she made during dinner...
