Ep 3. Remembrance of Things Past

The Criminal Minds season 6 episode 3, titled "Remembrance of Things Past," follows the Behavioral Analysis Unit (BAU) as they work to identify and capture a serial killer who has been targeting couples in Long Beach, California. The episode begins with the discovery of a married couple who have been brutally murdered in their home. The BAU is called in to investigate the case and quickly realizes that this is the work of a serial killer.

The majority of the episode is spent piecing together the killer's profile. The team investigates the crime scene and discovers that the killer was very organized and knew the couple's routine. They also find evidence that the killer has committed similar crimes in the past. This leads the team to believe that the killer has a very specific type of victim: married couples who live in suburban homes.

As the investigation progresses, the BAU discovers that the killer is motivated by a deep-seated sense of resentment towards married couples. The killer is targeting these couples as a way of punishing them for being happy and in love, something that they themselves are unable to experience.

The team eventually identifies the killer as a man named Vincent Perotta, who had a troubled childhood and a history of failed relationships. Vincent begins to escalate his killings, and the BAU realizes that they need to act fast before he can claim any more victims.

The climax of the episode is an intense confrontation between Vincent and the BAU. The team manages to successfully capture him, but not before he accidentally kills one of his own accomplices. The episode ends with the BAU reflecting on the events of the case and the toll that it has taken on them emotionally.

Overall, "Remembrance of Things Past" is a tense and emotional episode of Criminal Minds that explores the psychology of a serial killer and the toll that their crimes take on both the victims and the investigators. It showcases the BAU's unique approach to profiling and investigating cases, as well as the team's unwavering dedication to catching the bad guys and bringing them to justice.
