Fans of NCIS: Origins have a big reason to be excited ahead of Season 3. Mark Harmon is set to play a much larger role in the upcoming season, with the veteran actor expected to appear in every episode as the present-day version of Leroy Jethro Gibbs. The expanded role marks a major change from previous appearances and adds a new layer to the prequel’s storytelling.
Since the series debuted, Harmon has served as the show’s narrator and executive producer while Austin Stowell has portrayed the younger Gibbs during his early years at Camp Pendleton. Harmon’s occasional on-screen appearances have connected the past with the present, giving longtime NCIS viewers a familiar face as the story unfolds.
Season 3 will take that concept even further. The older Gibbs will reportedly be involved in a season-long storyline centered around a mystery connected to his time at Camp Pendleton during the 1990s. Rather than appearing only for brief moments, Harmon will help guide the narrative throughout the entire season.
The return is especially meaningful for longtime fans of the franchise. Harmon became one of television’s most recognizable leading men after portraying Gibbs for more than 18 seasons on the original NCIS. Although he stepped away from the flagship series after Gibbs chose a quieter life in Alaska, the character has remained one of the most beloved figures in the franchise.
The Season 2 finale left viewers with several unanswered questions that are expected to carry into the new season. One of the biggest moments saw Gibbs and Lala finally share a kiss, while another dramatic twist placed Randy in serious danger after he uncovered information he was never supposed to find. Those storylines are expected to play an important role as the series returns.
With Mark Harmon appearing throughout the season alongside Austin Stowell’s younger Gibbs, NCIS: Origins is set to offer fans an even deeper look into the character’s past while connecting it directly to his future. The combination of familiar faces, unresolved mysteries, and new investigations could make Season 3 the show’s most ambitious chapter yet.
