Ep 10. Internal Affairs

Internal Affairs is the tenth episode of NCIS: Los Angeles season 7. The episode begins with the team investigating a homicide case, which was intended to look like a suicide. Eric and Nell investigate the victim's financial records and discover a connection to Navy Lieutenant Commander Matthew Rousseau. Sam and Callen pay a visit to Rousseau at the Navy base, but he is uncooperative and insists on speaking only to his lawyer.

As the investigation progresses, Sam and Callen learn that Rousseau has been accused of stealing money from the Navy and is being investigated by Internal Affairs. The team begins to suspect that the murder they are investigating may be connected to the Internal Affairs investigation. Callen and Sam work together to try and crack the case, despite the fact that Rousseau is making it difficult for them to get to the truth.

Meanwhile, Kensi and Deeks work on their relationship, which has become strained since Kensi's return from Afghanistan. They receive a visit from Kensi's mother, Julia, who is concerned about their recent arguments. Julia provides some much-needed advice for the couple and helps them rekindle their romance.

Back at the office, Eric and Nell continue to work on the financial aspect of the case, revealing that the victim was involved in a money laundering scheme. They also discover that Rousseau's alleged theft of Navy funds may be linked to the case they are investigating. When the team questions Rousseau about this new information, he finally breaks down and admits to stealing the money. He reveals that he needed the funds to pay for his sick daughter's medical treatment.

As the episode draws to a close, the team discovers that the victim's death was indeed connected to the Internal Affairs investigation, and that the killer was someone within the Navy. The team manages to apprehend the killer and bring him to justice. The episode ends with Kensi and Deeks reconciling and the team coming together to celebrate their successful case.

Overall, Internal Affairs is an action-packed episode that highlights the strengths of the NCIS: Los Angeles team. The investigation is complex and engaging, and the subplots involving Kensi and Deeks, as well as Eric and Nell's financial detective work, provide ample opportunities for character development.
