Dexter's worst fears have been realized. Because of Debra's unrelenting pursuit, Miami Metro is just one step away from discovering the identity of the Trinity Killer. And Dexter can't let that happen. Arthur's arrest would not only deprive Dexter of a satisfying kill, it would also expose the secret life Dexter's been leading (as Kyle Butler) in his pursuit of this monster. Dexter must take drastic action to buy himself time to deal with Trinity in his own fashion. Meanwhile, Rita decides to confide in Dexter, which doesn't go as well as she'd hoped. LaGuerta and Batista's breach of ethics paints them into a very tight corner. And Arthur, who still can't understand why Dexter didn't simply turn him in, begins his own bloody investigation into 'Kyle Butler'.
Things were already tense to begin with and this episode takes full advantage of that. Great acting by Michael C. Hall and Jennifer Carpenter who developed their characters to a greater extent. This episode gave me some closure and left me surprised. Every season has a new aspect of Dexter's life shown in each serial killer and in this case we are shown that the serial killer is basically his mirrored self with an extra 20 years. The search for a hope of a normal life included with his dark passenger begins to crumble with the turn of events and finale could not have been better set that with this cliffhanger!
10/10 for me!
