NCIS: Los Angeles season 11 episode 10 is set to arrive later this week, with the title "Mother." There are a lot of happenings here, especially since this would be the 250th episode of the procedural drama series. The upcoming episode will likely focus on Hetty Langer as well, as she might be in danger.

In the synopsis of NCIS: Los Angeles season 11 episode 10, a former black ops agent name Akhos Laos returned, and he was originally recruited and trained by Hetty. Now, he came back to seek revenge on Hetty for the life she introduced him to.

Based on the episode description, it seems like Hetty will be the center of NCIS: Los Angeles season 11 episode 10. The upcoming episode will likely explore more chaos, and also a chance to see the impacts of violence on Ahkhos and why he wanted to get revenge on Hetty.

In another report, the technical operator of the team, Eric Beale, returned in the previously-aired episode of NCIS: Los Angeles, titled "Kill Beale: Vol. 1". Barrett Foa, who plays Eric, has been missing most of the season, but he finally came back in episode 9.

Now, many are wondering if Eric is not leaving anymore and back for good. The previous episode focused mostly on the character and his whereabouts, and the team rescued him as soon as they found out he's in trouble. According to a report from Express, the nerdy NCIS team member is finally back to the series full time.

Foa has been away from the series as the network granted him a leave of absence to pursue his passion for theater. The actor has been starring in a production of Angels in America, and although he's away for quite some time in the CBS series, Foa is happy to be back on set with the cast and crew.

Meanwhile, Deeks wasn't present in NCIS: Los Angeles season 11 episode 9. The reason for his absence is because the character was off doing official LAPD business, but that doesn't mean he'll be away for so long. Additionally, Eric Christian Olsen, who plays Deeks, will be more involved in the upcoming NCIS: Los Angles season 11 episode 10, as he co-wrote "Mother."

NCIS: Los Angeles season 11 episode 10 will air on Sunday, Dec. 1, on CBS.
