Endgame

When a doctor is found murdered, Director Vance shows up at the crime scene, claiming he's seen the type of murder before. The director confirms that the killer was a North Korean assassin, named Lee Wuan Kai (first seen in the NCIS: Los Angeles episode "Killshot"). The team finds that Kai has left her DNA on the victim's body for them. The director is completely surprised and shocked when Kai calls him at home and is sitting in his driveway. As the investigation continues, the team discovers that Kai is in town to kill a North Korean official. Meanwhile, McGee's new love interest, Amanda turns out to be working for the North Korean government and is shot by Kai before dying in McGee's arms. They discover that Kai is in D.C. to kill all the men who made her into an assassin as a child. Vance returns to his home to find Kai pointing a gun at his wife. Kai reveals that she is there because she wants Vance to kill her in order to finally end her pain. The director lowers his gun to help her, but his wife finishes the job instead. ­
