During the morning drivetime, after a chick rear-ends a pickup truck (while applying makeup), a bomb in the bed explodes, and the man in the truck runs away; the man, Knowles, is a Marine former second lieutenant with a medical discharge under honorable conditions; FBI agents bust Knowles; Granger wants Callen and company to find out why the team did not previously know about a terrorist plot in the LA area. Nate resurfaces and says that the FBI has it wrong; Kensi and Deeks check out a diner and a goth waitress; the Hoover in charge behaves in an arrogant and obnoxious way; Kensi and Deeks ride a pair of bikes; G uses a light touch with a lock, but a car explodes. Kensi and Deeks trace a cello, which causes G and Sam to check a bedroom, which contains clues, which enable the team to look further and to assemble the puzzle and to minimize the damage of the third bomb. The Hoover in charge eats crow, the bad guy stays in custody, and things begin to look better.

When Adam Malnick is apprehended by Agents Callen and Hanna, he makes a wise crack about giving the agents a "slow clap" for their efforts. The character Malnick is portrayed by Eric Jungmann, who appeared along with Eric Christian Olsen (Deeks) in Not Another Teen Movie
(2001), in which the "slow clap" was a running joke. See more
The cello looks completely generic in the photograph. Not even a skilled luthier could identify this specific instrument by a cell phone picture. At the very least the picture would need to show the paper label pasted inside the instrument but probably he would have to have a look at the real instrument. Or maybe at his receipt, stuck to the case's handle. See more
