Dexter wants to kill someone and focuses on the recently paroled killer Ray Speltzer. Dexter is convinced that Speltzer will kill again and tries to convince Deb that he can eliminate him before some young woman gets killed. Deb won't hear of it....but begins to question her own moral code when Dexter proves to be correct. Written by garykmcd

Dexter Morgan: [narrating] I feel trapped. Like there's no escape. And it's not because I'm at the Post Office. She's got me penned-in like a caged animal. And an animal is never more dangerous than when it's backed into a corner.

This Murder Is on Debra
26 July 2014 | by claudio_carvalhoSee all my reviews

Dexter is stressed with Debra's surveillance on him and he selects his next victim, the killer Ray Speltzer, to calm down his dark passenger. However he decides to get rid of Louis Greene first and he sends the hand of the Ice Truck Killer to Miami Metro and a DVD with Louis having sex to Jamie; consequently Louis is fired by Masuka and dumped by Jamie. Meanwhile Isaak continues to seek out Viktor and keep track of Kaja's bracelet and he finds Dexter's motor boat at the marina. Isaak and his men find Louis trying to sink the boat and they learn that the owner is Dexter before killing Louis. Dexter believes that Ray will kill again and tries to convince Debra to let him execute the killer to protect his next victim. However Debra decides to follow the book and to use the law to catch Ray. Who will be right in the end?

"Buck the System" shows the fight between Debra and her moral principles using the law against Harry's code followed by Dexter to satisfy his dark passenger. The revengeful Louis finds what he was looking for when he decided to mess with Dexter but without his participation. I look forward to see the fate of Isaak Sirko now that he will cross path with Dexter. My vote is seven.
