Blowback is the third episode of the fifth season. It was released on 17 October 2008. Agent McGowan makes his move against Don, and Colby gets a little too involved with a stunning suspect in a cop killing.
blowback /ˈbləʊˌbæk/ noun
1. the escape to the rear of gases formed during the firing of a weapon or in a boiler, internal-combustion engine, etc.
2. the action of a light automatic weapon in which the expanding gases of the propellant force back the bolt, thus reloading the weapon
Here the word conveys a sense of the ramifications and lingering consequences of a course of action, and perhaps the risk to others caught in the blast.
David Krumholtz and Morena Baccarian were in Serinity (2005).
Many elements of this episode's plot are taken from the movie L.A. Confidential (1997), which in turn was adapted from James Ellroy's novel of the same name. For example, the initial crime in both is a murder of a whole diner full of customers, most of whom are found in a back storage room; in both, the plot hinges on a prostitute named Lynn who sleeps with one of the investigating officers; in both, a prominent member of the Hollywood community is being blackmailed with sexually compromising photos before his blackmailer gets murdered. When Lynn Potter (Morena Baccarin) is first interviewed by the FBI, she says that on the night in question, she had fallen asleep on her couch while watching L.A. Confidential (1997).
When Don is talking to his girlfriend about going to New York, he has a coffee cup on the arm rest of his chair and when the camera crosses back to him the cup disappears.
When Lynn Potter's car blows up we see several shots of the file in the drivers foot-well with fire coming from both the left and the right hand side as we see it, then when Cody retrieves it there is only fire coming from the left side and the right side shows no sign of the fire ever touching it.
