Dexter must deal with Rita's menacing husband. Debra goes on a date with the prosthetics expert who made prosthetic legs for an Ice Truck Killer survivor. Debra and Angel are investigating the Ice Truck Killer and discover a familiar name with speeding violations near the scene of the Ice Truck Killer's third murder. Dexter investigates Sergeant Doakes's knife victim; he already knows the killer's identity but needs time to locate him. The Ice Truck Killer is finally apprehended, but Dexter doubts that they have caught the correct man.
The seventh episode of Dexter is another good episode and is on par with the previous episode of tension and wanting more to happen. I liked this episode because many things happen here such as a return of an old character and such. All I can say is that I really liked this episode and the ongoing developments of the Ice Truck Killer.
This episode, "Circle of Friends," has a suspect that is believed to be the Ice Truck Killer being apprehended but Dexter isn't so optimistic if he is actually the killer. Meanwhile, Rita has to deal with her menacing soon-to-be-ex husband who just was let out of prison on parole.
Overall, this is a very good, tense episode. I really liked it because there were many things to pay attention to and you will most likely not get bored. There are a few surprising developments here to keep in mind as well. I rate this episode 9/10.
