NCIS Season 24 Cast Shake-Up: Big Changes Coming to the Team in New Episodes

NCIS is heading into its 24th season with major changes expected inside the Major Case Response Team, following a season filled with emotional storylines and a dramatic cliffhanger.

Season 23 ended on a tense note, with the team dealing with the aftermath of several major developments. The season included unexpected reunions, including Ellie Bishop’s return, as well as the death of Director Leon Vance, which left a leadership gap inside the agency. The finale also shifted focus toward more personal stories within the team, especially as long-running character relationships were explored in greater depth.

One of the biggest turning points came in the final episode titled “Sons and Daughters,” which ended on a cliffhanger involving Timothy McGee’s secret son, Mateo. The storyline revealed that Mateo may be connected to suspicious activity that could put the agency at risk. Nick Torres became the first to suspect something was wrong, which led to a confrontation that ended in a gunshot, leaving fans waiting for answers going into season 24.

Despite the dramatic ending, NCIS showrunner Steven D. Binder has confirmed that no main characters will die as a result of the shooting. However, that does not mean the team will remain unchanged going forward.

Wilmer Valderrama, who plays Nick Torres, recently spoke about the upcoming season during an appearance at the 2026 Los Angeles Latino International Film Festival. While careful not to reveal too many spoilers, he did hint that viewers should expect major shifts when the show returns.

He said, “Look, every couple of years, you guys know NCIS has to make sure you’re watching. So we shake up the TV a little bit and we listen. And we listen to where you as fans want to see us do. So we always really pay attention to what our fans want to really experience on the show.”

Valderrama also teased that the new season will bring noticeable changes to the team structure. He added, “Next season, there’s some major changes and there are some major additions.” He even joked about the uncertainty surrounding his own character, saying, “What does that mean for Torres? I can only hope that he makes it out alive.”

The death of Vance has created a power vacuum inside NCIS, and that opening is expected to play a major role in the new season. A returning antagonist, Gabriel LaRoche, is also expected to take advantage of the situation as leadership struggles continue inside the agency.

The finale also brought back Kayla, Vance’s eldest daughter, adding another emotional layer to the story. At the same time, questions remain about whether CBS will introduce entirely new characters to strengthen the team moving forward.

At present, the core NCIS team includes Alden Parker as leader, along with agents McGee, Torres, and Jessica Knight, as well as support staff Kasie Hines and Jimmy Palmer. Season 24 may expand that lineup, shifting the long-standing structure of the series.

NCIS has evolved several times over its long run, especially after the departure of longtime lead Leroy Jethro Gibbs. With new leadership already in place and possible new agents joining the team, season 24 appears set to mark another turning point in the show’s history.
