Ep 15. Mr. and Mrs. Anderson

The episode "Mr. and Mrs. Anderson" is the fifteenth episode of the ninth season of Criminal Minds. In this episode, the Behavioral Analysis Unit (BAU) is called in to investigate a series of murders of couples in the suburbs of Northern Virginia. The latest victims are a young couple, the Andersons, who were killed in their home while their baby was sleeping in another room.

As the team begins their investigation, they learn that all the victims were couples who lived in the same neighborhood and were killed in their homes. The murders appeared to be random, but the team discovered that the husbands all had similar physical features, leading them to believe that the unsub (unknown subject) may be targeting men who resembled someone from his past.

As the investigation continues, the team discovers that the unsub, a former marine named Jack Westbrook, had a traumatic childhood during which his father was abusive towards him and his mother. The team learns that Westbrook had been sent to a military academy as a teenager and had not seen his parents since. His parents had since moved to the same neighborhood where the murders were occurring, and Westbrook had started to see his father's features in the husbands he was killing.

The BAU is able to track down Westbrook to his home, where they find him hiding in the attic. He had taken the Andersons' baby with him and was planning to raise him as his own child. The team is able to talk Westbrook down and convince him to let the baby go unharmed.

In addition to the main case, the episode focuses on the personal lives of the BAU team members. Hotch deals with his son Jack's reluctance to attend school, while Rossi reminisces about his past on his birthday. Meanwhile, JJ deals with the aftermath of a shooting she witnessed in the previous episode.

Overall, "Mr. and Mrs. Anderson" is a tense and emotional episode that delves deeply into the psyche of the unsub while also exploring the personal lives of the BAU team members. It is a gripping installment in the series that balances action and suspense with character development and emotional depth.
