"NCIS Los Angeles" Season 6, episode 4 "The 3rd Choir" was written by R. Scott Gemmill and Dana Scanlon. It was directed by Diana C. Valentine. Here's what happened in "The 3rd Choir." The "NCIS Los Angeles" team found out that Mattias Draeger (Jürgen Prochnow) is the one targeting Hetty. They searched for Mattias all over Los Angeles to stop him from harming Hetty and causing more mayhem.

Speaking of Hetty, she jumped into a dumpster in this episode and also walked out of the Congressional hearing. And, she got to shoot Mattias in the leg when her team eventually found him.

Meanwhile, Operational Psychologist Nate Getz (Peter Cambor) paid Nell a visit to help her get over the trauma that she recently experienced while on a mission. She went undercover as Hetty and almost died in the process.

As for Deeks and Kensi, or "Densi," they were seen by Granger coming in to work together. But, it is still not clear if they are in a romantic relationship already. Chief Investigator Ava Wallace (Aisha Hinds) also showed some interest on Sam, unaware that he is actually married because he left that information out of his file.
