Trivia: In the opening scene where Jim Phelps' home town friend Connie Hastings' car gets a flat and subsequently chased by the town's Vietnam veteran suffering from post war syndrome the state road sign is clearly visible. This episode takes place in the fictional town of Norville in Norville County. No state is mentioned, yet one can see the California state road sign as Highway 23 which runs from Malibu in LA county to Moorpark in Ventura county California
It's never explained why Paris stages the scene with Dana and attacks Keith. If they believe Keith is the killer, he's killed other women without their boyfriends having fights. If they think the killer is someone else, there's no reason to stage the fight either.
Doug does not appear in this episode.
A purely personal mission - there is no tape briefing at the beginning.
