The article discusses the popular television series NCIS and speculates on the characters who will not be returning for the show's 21st season. NCIS is a long-running American crime procedural drama that focuses on a team of special agents from the Naval Criminal Investigative Service. With the show's immense popularity, it is inevitable that some characters will come and go, and this article aims to shed light on who might not be returning for the upcoming season.

While the article does not provide explicit details about every character, it highlights some potential departures. One character who may not be returning is Special Agent Timothy McGee, portrayed by Sean Murray. The article suggests that the actor's involvement in other projects and his desire for new challenges might lead to his exit from the show. If true, this would be a significant loss for the series as McGee has been a beloved character for many fans since his introduction in the early seasons.

Another character whose return is uncertain is Maria Bello's Special Agent Jacqueline "Jack" Sloane. Bello joined the cast in 2017 and has since become a well-liked presence on the show. However, the article mentions that Bello's contract will expire after the 20th season, implying that this might be her final season on NCIS. If her departure were to occur, the show would once again have to adjust to the loss of a key character.

The third character potentially not returning is the team's leader, Special Agent Leroy Jethro Gibbs, portrayed by Mark Harmon. While Harmon's future on the show has not been officially confirmed, the article speculates that due to the actor's reduced screen time in previous seasons, this might be an indication of his eventual departure. Losing such a central character like Gibbs would undoubtedly have a significant impact on the show.

Additionally, the article notes that director Vance, portrayed by Rocky Carroll, could also be leaving. Carroll has been with the show since 2008 and has become a much-valued member of the NCIS team. However, the article suggests that his character's departure could bring new opportunities and exciting changes to the series.

As viewers anxiously await the upcoming 21st season of NCIS, speculation regarding the fate of these beloved characters continues to grow. Will McGee, Sloane, Gibbs, and Vance bid farewell to the show, or will they remain fixtures in the team's crime-solving efforts? Only time will tell, leaving fans eager for the premiere to find out what lies ahead for their favorite characters.
