Henrietta `Hetty' LangeEdit
Henrietta "Hetty" Lange is the operations manager assigned to OSP Los Angeles. The character made her first appearance in the series premiere on 22 September 2009. Despite her small size, Hetty is very intimidating and does not hesitate to use the resources to ensure the safety of her Agents. She replaced Lara Macy following an assassination attempt on G. Callen and has remained in the position of Operations Manager to this day.
Marty Deeks is the liaison between the Los Angeles Police Department and OSP Los Angeles. The character made his first appearance in the nineteenth episode of the first season on 6 April 2010. A Los Angeles Police Department detective, Deeks like Eric Beale enjoys surfing. Deeks has a bomb-sniffing dog named "Monty" and he is currently partnered with Kensi Blye.
Nell Jones is an intelligence analyst assigned to OSP Los Angeles and in addition, is paired with Eric Beale who disliked her at first but there are hints suggesting the two might have fallen for each other. The character made her first appearance in the fourth episode of the second season on 5 October 2010.
Lara Macy was the Special Agent in Charge of the Office of Special Projects the time of events chronicled in the two episodes entitled Legend Part One and Legend Part Two respectively. Following an attack on G. Callen, Macy was subsequently reassigned to a posting overseas in France. Unfortunately, while back in the U.S, she was murdered by a member of the Reynosa Cartel with her body being set alight and left in a fire pit. Both the Major Case Response Team and Office of Special Projects were left devastated by her death.
Dominic Vail is a Special Agent assigned to OSP Los Angeles, the character made his first appearance in the series premiere on 22 September 2009, but in the episode "Missing" he was kidnapped, and then reported missing. No one had seen him until "Found" when it was revealed that he was still alive and held hostage by terrorists. The special agents were able to successfully find him only to be caught in a gunfight with terrorists. Dom died during the escape attempt when he jumped in front of Sam to save him from the shooter with his death leaving the OSP team completely devastated. Dom's role as being Kensi Blye's partner was eventually taken over by LAPD Detective Marty Deeks while his position of being the newbie or the Probie of the team presumably remains vacant to this day.
