As the hunt for Ice Truck Killer continues, posed body parts are discovered which appear to be the calling cards of an increasingly impatient killer. The Ice Truck Killer escalates his killing spree, leaving body parts of his latest victim at sites connected to Dexter's childhood, which leads Dexter to confront his dark personal history. As Halloween approaches, Rita kidnaps a barking dog from a cynical owner because it keeps her children up at night, and gives it to a loving family. Meanwhile, Lieutenant LaGuerta seeks to comfort the mother of the latest Ice Truck Killer victim. Dexter finds the victim mutilated but alive and strapped to a table for Dexter to kill. Instead, Dexter reports the crime scene anonymously to his sister. The pressure on Sergeant Doakes escalates when Guerrero's associates begin following him.
I think it probably has to do with my dislike of both the actress and character of Laguarta...so whenever she has a lot of screen time, I dislike it. I actually skip ahead when she's on...if it doesn't seem like it's relevant to the story. There is a lot of fluff in Dexter's episodes. It's ok...but just seemingly filling up all 55 to 60 minutes one way or the other
