5 Years Later, an NCIS Fan-Favorite Is Officially Back

2026 has been the year of reunions for NCIS, though no show has felt that more than the prequel series, NCIS: Origins. Season 3 brought the flagship's longtime lead, Mark Harmon, back in front of the camera as Leroy Jethro Gibbs for a season-long arc that sees the former head of the Major Case Response Team confronted by the ghosts of his past and finding his peaceful post-career existence shattered in an instant. To get to the bottom of who attacked him in the Alaskan wilderness, Gibbs has been retracing his steps and reuniting with people in his past for help. In tonight's episode, that will include Michael Weatherly, who's now NCIS director and could use his connections to get what his ex-boss and mentor needs. Tony DiNozzo isn't the only agent re-entering his life, though.
