The two back-door pilot episodes of NCIS: Los Angeles teased the first meeting between Gibbs and Macy, which may finally be shown onscreen for the first time. Special Agent Jethro Gibbs and Operations Manager Lara Macy worked together in the two-part pilot episode as Gibbs’ team joined forces with the Los Angeles unit, Office of Special Projects (OSP), to investigate the murder of a marine that’s connected to a terrorist cell. During this case, Gibbs and Macy unpack their complex and uneasy relationship in connection to an emotional part of Gibbs’ past.
