Agent Meredith Brody (Zoe McLellan) will be forced to relive one of the darkest moments in her life in the upcoming episode of the CBS series "NCIS: New Orleans."

Out of all of Special Agent Dwayne Pride's (Scott Bakula) squad members, the tall brunette is the most secretive. Little has been known about her personal life and even her partner Christopher LaSalle (Lucas Black) had to dig deep to learn some information about her. Brody joined NCIS NOLA after requesting reassignment from her Chicago department. She was discovered by Pride and LaSalle when she worked alongside them while investigating the death of a congressman and another agent.

Back in season 1, it was revealed that Brody had a twin sister named Emily, but she was killed in a drunk driving incident. It was also made known that she did not wish to talk about her loss, especially with her mother. In the upcoming episode titled "If It Bleeds, It Leads," TV.com reports that the female agent will have no choice but to remember her dead sister when a recent road accident draws the interest of the Naval Criminal Investigative Service (NCIS).

It appears that a party bus hit a sailor who was strolling around French Quarter. Upon investigation, the team will discover that it has strong similarities to Brody's sister's accident. Could the perpetrator in the sailor's case be the same man who killed Emily?

Meanwhile, the NCIS members are busy preparing for the city-wide celebration of St. Patrick's Day.

Last episode, the entire squad investigated the death of a Navy captain who was murdered while being interviewed by a local radio station. The victim had a spotless record and no one could tell if he had an enemy or not. The DJ in the station was his former Petty officer, who was heavily involved in charity. It turned out that she and the captain were lovers. The victim was killed by his wife, who learned about his infidelity.

"NCIS: New Orleans" season 2 airs Tuesdays at 9 p.m. on CBS.
