"NCIS: Los Angeles" season 7 episode 19 is titled "The Seventh Child," and it will put Callen (Chris O'Donnell) in the spotlight as he tries to save a young boy who has been brainwashed by terrorists. It will also show Marty Deeks (Eric Christian Olsen) and Kensi Blye's (Daniela Ruah) discussion about building their own family.

The episode's synopsis reads, "Callen and the team try to save a child in imminent danger who has been brainwashed by a terrorist cell. Also, Deeks and Kensi discuss having children."

In a recent trailer, Sam Hanna (LL Cool J) and Deeks are seen storming a house. When they enter a room, Sam looks terrified and distressed. Sam then tells everyone to get out of the house and have everyone in the surrounding area evacuate their homes. This only means that the terrorists have planted a bomb in it.

Fans have since speculated that the child Callen is trying to save may know how to defuse the bomb.

Meanwhile, Deeks and Blye have been dating for a long time now that taking their relationship to the next level — having children, that is — will no longer surprise the fans of the show.

The two had a scene in the last episode that avid viewers had gushed about. When Kensi showed up at the boatshed, she heard Deeks whistling in the shower. She was confused at first why in the world was he having a shower at work and eventually got mad. Deeks had to tell the truth that Kensi's mess in their own bathroom has been bothering him all this time, but he cannot find the courage to tell her about it. She has 14 different bottles of conditioner and 11 more bottles of shampoo!

Kensi chose to sulk about this revelation at first, but she eventually gave in, accepted the problem, and decided to make a change.

Watch the next episode to see what else is in store for them. "NCIS: L.A." season 7 episode 19 premieres this Monday, March 21, at 10 p.m. EST on CBS.
