NCIS fans are in for a wild ride as Season 23 kicks off with a shocking twist—Sean Murray, who plays Special Agent Timothy McGee, is stepping away, and Mark Harmon is officially back as Leroy Jethro Gibbs. After two seasons away from the spotlight, Harmon’s return marks a major turning point for the long-running series, reigniting excitement and speculation among loyal viewers.

According to insiders, the decision was made quietly behind the scenes, with Murray’s exit described as respectful and storyline-driven. While McGee has been a steady presence since Season 1, producers felt that Gibbs’ return would bring fresh energy to the team and the show’s dynamic. The door remains open for Murray to make guest appearances later in the season.

Harmon’s comeback has already started filming, and sources say Gibbs will return under unusual circumstances, possibly linked to an international case that forces him back into action. Longtime fans can expect emotional reunions, intense investigations, and a shift in leadership that could redefine the future of NCIS. One thing’s clear: Season 23 won’t be business as usual.
