Blye, K., Part 2

The episode was written by Dave Kalstein and directed by Terrence O'Hara, and was seen by 15.85 million viewers in its original American broadcast.

At HQ, the OSP team discover Granger has gone off the radar and begin to suspect him to be the killer as he was in the same unit as Donald Blye and Harris, codenamed 'Oscar Sierra'.

Kensi finds she is being followed but surprise attacks the driver and steals the car, whose Satellite Navigation System leads her to a house where she sees a man and a woman talking.

After Eric and Nell find footage of Granger fleeing the shooting, Callen and Sam discover him in Kensi's ransacked apartment, and bring him to Hetty in the NCIS OSP Boatshed for answers.

Granger then comes clean and reveals he had two suspects all along: Kensi Blye and Peter Clairmont, the Commanding Officer of Oscar Sierra who died in a car crash in 2006, but upon closer inspection of the files Granger concluded the crash was staged, and that Clairmont is actually alive and faked his death because he killed Donald Blye.

Granger calls Kensi and reveals to all that Oscar Sierra was responsible for the death of Brad Stevens, an American reporter.

Kensi goes back to her mother's house and lures Clairmont and his team there whilst leaving a clue for Callen and the others to find her.

As she turns her back on him, Claremont, seeking revenge uses the last ounce of his strength to produce his gun with the intention of shooting Kensi but Granger, having quickly spotted the move draws his own gun and shoots Claremont, killing him while also saving Kensi's life much to the shock and surprise of Callen, Sam and Deeks.
