Description

The team investigate the murder of two businessmen and later find out that a spy/agent named Chameleon who can take on any personality or facade he likes is responsible for the killings. When the Interpol Agent the team were working with is murdered, Granger takes over the case, forcing the team to report to him while still resenting his involvement. But despite their best efforts, Chameleon manages to evade them but not before calling Callen from an unknown location and then telling the NCIS Special Agent that he's going to kill him. Later, under pressure from both Hetty and Callen, Granger finally tells them the reason for him coming to Los Angeles: he's here to catch a killer and the camera then shows him looking over at Kensi, suggesting it might have something to do with her.
