When NCIS: Los Angeles returns from its summer hiatus, two of the team's agents are going to need a little TLC.

Sam (LL Cool J) and Deeks (Eric Christian Olsen) may have physically survived being tortured at the hands of Siderov (Timothy V. Murphy) but the pair will each have trouble dealing with the emotional fallout of "Descent."

Nate's comeback episode, which is titled "Impact," will feature an investigation regarding the demise of a Navy Admiral and a journalist, according to Carter Matt. However, the procedural aspect will probably mostly serve as a backdrop to observe the changes wrought on the characters as viewers see them back at work for the first time.

NCIS: LA will return to CBS on Sept. 24.
