NCIS: Los Angeles season 12 episode 4 is coming within two weeks on CBS. No new episode is airing this coming Sunday because it is the weekend after Thanksgiving. Despite the wait, viewers will see some familiar faces showing up in "Cash Flow" once it arrives.

For instance, Bar Paly is returning as Anna Kolcheck in NCIS: Los Angeles season 12 episode 4. Fans will get the chance to see more of her spending time with G. Callen (Chris O'Donnell). It has been already teased that the two will have an interesting storyline in the latest installment, in which Anna isn't on the run.

The two may think about the life they wanted to build together now that they reunited. Anna's return is also an indication the series will deliver more personal stories about Callen -- beyond just the action. It would show O'Donnell's character is away from his job.

But aside from bringing back some familiar faces, the upcoming episode delivers another case for the team. Thieves found the murdered body of a Navy reservist in the middle of a robbery. Now, the team needs to work with the burglars in order to find the killer and solve the case.

Moreover, the fourth episode will continue to follow Kensi Blye (Daniela Ruah) and Marty Deeks' (Eric Christian Olsen) storyline, wherein they still contemplating their future. The married couple struggles whether or not they're ready to take a leap and buy a new house.
