Warning: SPOILERS for the NCIS/NCIS: Origins crossover are ahead!

NCIS and NCIS: Origins may take place in two different time periods, but that didn’t stop CBS from bringing them together in a unique way. The crossover between these two procedurals just finished airing on the 2025 TV schedule, with the connective thread being a case that began in 1992 and was revisited in 2025. One of the highlights of this crossover was Mark Harmon reprising Leroy Jethro Gibbs on Origins on camera for the first time since it began, though he’s remained a steady presence on the prequel as its narrator. CinemaBlend learned the details about Harmon’s big return, as well as where things stand with Gibbs in the present day.
