Mark Harmon's possible return to the show NCIS is a big question among fans. Currently, Gibbs, Harmon's character, is living in Alaska. NCIS is a police procedural drama following the special agents of the Naval Criminal Investigation Service. Harmon played Gibbs for 19 seasons and left the series at the start of season 19. However, there are hints that Gibbs may return in the future, with fellow cast member Rocky Carroll suggesting that as long as the show continues, there will always be a possibility of Gibbs making a comeback. Harmon himself has also hinted that Gibbs was purposely written out in a way that allows him to return. NCIS executive producer Steven D. Binder has also suggested that Gibbs may return in future seasons, emphasizing that fans should never count him out.
