NCIS, Season 23

Mark Harmon is set to return to the NCIS universe in a special crossover event uniting NCIS and NCIS: Origins. The upcoming episode brings back his iconic character, Leroy Jethro Gibbs. The storyline connects past and present investigations across both series.
NCIS Season 23 Episode 4 is titled Gone Girls and it will air on November 4 on CBS.
Origins would deliver its own tribute to fan-favorite Donald “Ducky” Mallard, it was hard to know what to expect from this venture or whether Adam Campbell could reprise the role in a way that aligned with this spinoff.
As NCIS: Origins moves forward, fans can expect emotional complexity, professional stakes, and romance that’s both teased and restrained. Gibbs’ journey isn’t just about love — it’s about the making of a leader, a partner, and an agent whose choices reverberate across the franchise.
