The daughter of a professor and a journalist, Brody later graduated from Michigan State University and she later joined NCIS.
After becoming a fully-fledged NCIS agent, Brody presumably carried out a few assignments of her own before being assigned as the Special Agent Afloat on board the USS Moultrie.
In 2010, she confronted a terrorist on board the ship but before she could shoot the suspect, they were able to detonate an Improvised Explosive Device (IED) which presumably resulted in possible damage to the ship as well as fatalities.
In the aftermath of the bombing, Brody was later reassigned to the NCIS Chicago Office.
NCIS Season 11
While at the Chicago Field Office, Brody requested a reassignment, stating that she needed a change.
As such, Brody was sent to assist the New Orleans field office to help Agents Dwayne Cassius Pride and Christopher LaSalle into the death of Congressman and former NIS agent, Dan McLane despite Pride being strongly against having more manpower being sent to New Orleans and Pride even insisting that he and LaSelle could handle the case themselves.
Despite this, Brody later proved herself to be a huge help and after the case, was reassigned to New Orleans on a permanent basis, resulting in her becoming an official member of the New Orleans team.
NCIS: New Orleans Season 1
In the Season 1 episode, "Careful What You Wish For", Brody was investigated after she witnessed the death of an NCIS Special Agent who was shot dead while the two of them were providing protection for an Admiral.
It was later revealed that the explosion on the U.S.S. Moultrie where Brody had been assigned to as an NCIS Agent Afloat had been caused by a disgruntled Petty Officer Third Class Jerry Cooper who had set off an explosive device with the attack causing extensive damage to the ship and also resulting in five fatalities as well.
Brody also revealed that she had hesitated because the Petty Officer's eyes had reminded her of her dead twin sister, Emily Ann Brody who had been killed by a drunk driver only days earlier.
NCIS Season 13
Three years later, Brody appeared in the NCIS Season 13/NCIS: New Orleans Season 2 crossover episode, Sister City: Part 1 (episode).
Brody is a tall woman in her late thirties, early forties with short brown hair and brown eyes although she is later seen with longer hair during NCIS: New Orleans Season 2.
She wears various jackets, shirts and trousers along with high heeled boots while wearing her NCIS badge on the right side of her hip.
While processing a crime scene, Brody dons an NCIS windbreaker and cap while maintaining her high-heeled boots.
While pursing a criminal, Brody wears the NCIS cap and also dons the traditional NCIS bulletproof vest. She wears a hand-held headset that is a small blue or black earwig that she puts into her left or right ear, enabling her to communicate with her teammates. Like Pride and LaSelle, she also has the holster containing her Glock placed at her back so that she can freely grab it in the event of danger. In the backdoor pilots, "Crescent City" and "Crescent City Part 2", as a visiting agent, Brody originally carried a SIG-Sauer P228 but upon officially transferring to New Orleans and subsequently joining the NCIS: New Orleans team, she exchanged her SIG-Sauer P228 for a Glock 26 which she carries to this day.
Similarly to NCIS Special Agent Timothy McGee of the NCIS Major Case Response Team in Washington D.C., Brody is left-handed and like NCIS Probationary Agent Eleanor Bishop, Brody wears her watch on her right hand
Like all federal agents, Brody is trained to process a crime scene and interrogate suspects. She is also an expert at handling interrogations.
Hand to Hand Combat
Due to her possessing a black belt in Aikido, Brody is skilled in hand-to-hand combat and is capable of taking down an opponent.
Gibbs and Brody previously worked together on a classified operation. When Dwayne Pride attempted to ask Gibbs about the operation, Gibbs replied that it was classified. Whether the operation occurred during Brody's tenure aboard the Moultrie or during her time in Chicago is unknown.
Pride is unsure what to make of Special Agent Brody, he initially was slow to trust her especially after he finds out that she requested reassignment. Although, after becoming acquainted with Brody over breakfast and reviewing a file pertaining to Brody he was willing to give her a chance to prove herself.
By the end of the McLane case, Pride offered Brody a position in his team and she accepted.
LaSalle first met Brody in the NOLA office and they slowly warmed up to form an amicable working relationship. LaSalle also helped Brody find a new place to stay in New Orleans.
