Cold Squad

This two-part episode (The Filth, And the Fury) was named after the Sex Pistols documentary The Filth and the Fury.

Summerhill reveals that he is thirty-two years old, and was the same age as Ali's boyfriend Paul Deeds, with whom he attended Queens. When Ali tries to clarify some information with Paul, he comments that he and Ian knew each other nearly twenty years earlier. It would have been more accurate for him to say it had been nearly ten years.

Since Nicco is back on the street in this episode, his title is sergeant as opposed to detective.

This isn't the first time that Ali has interrogate swingers while looking into a case. In the season two episode Merv Doucette, Ali and her partner, Tony Logozzo, check out a group of swingers to find out who murdered a retired school teacher.

Pierre Martin's definition of double jeopardy (can't charge a person twice with the same crime) is the typical misunderstanding of the double jeopardy rule. For example, if Mr. X is convicted of murding Mrs. X in 1985 but she turns up alive and well and he kills her in 1995, he cannot be recharged with the 1985 murder, but he can be charged with the 1995 murder. This false belief of the definition of the double jeopardy law is perpetuated by films such as Double Jeopardy starring Ashley Judd and Tommy Lee Jones, where the character of Travis states that Libby cannot be charged for killing the husband she was convicted of seven years earlier. This can be found in part 11(h,i) of the Canadian Charter of Rights and Freedoms, and the fifth amendment of the U.S. Constitution.

Harper talks to Ali about how he and Wanda adopted a baby boy, David, then learned she was pregnant. Harper's two daughters become focal points in following episodes, but his son is never mentioned again.

After finding the mass grave in the basement, one of the firefighters is sick to his stomach and throws up. When he is throwing up, the camera is zoomed in on his face, then pulls back out. The floor beneath him is clearly visible, and although he had just been seen throwing up, there is nothing on the floor.

Tony's birthdate is revealed to be 14 August 1946.

Logozzo reveals that he divorced Vivian (wife #3) in 1993.

Jill is working for Cold Squad doing research while working toward her doctorate in abnormal psychology.

Although this was the third episode aired, it's actually the pilot, in which the characters and the concept of the "Cold Squad" are introduced.

Stone (whom Logozzo refers to as Jill Jr.) is doing her doctorate in Abnormal Psychology at University of British Columbia. She and McCormick met while McCormick was doing Homicide and had asked her for her help.

McCormick (a sergeant) recently transfered to Cold Squad after three years of being partnered with Gallagher in Homicide.

Logozzo ended up in the basement (where Cold Squad works) after years on the force sent him on a downward spiral into the bottle. He has three children (Ben, Lisa and Carmen) with three different women. He's a smoker, and is bitter because he failed the sergeant's exam and McCormick was put in charge of Cold Squad.
