In a poignant tribute to David McCallum’s character, Dr. Mallard, NCIS Season 21 sees the significant return of Tony DiNozzo, portrayed by Michael Weatherly. Although Mark Harmon’s Gibbs is notably absent, Weatherly’s comeback adds emotional depth to the storyline. Titled “Stories We Leave Behind,” the episode weaves the team’s grief over Mallard’s death with a case he was working on, featuring flashbacks of key moments with Mallard. DiNozzo’s return is especially impactful as he offers support to Palmer, Mallard’s protege, marking his first appearance since Season 13.
DiNozzo’s return sparks speculation about the potential future of NCIS, a contrast to the slim chance of Gibbs returning full-time. With DiNozzo’s past ties to the team and Michael Weatherly’s expressed interest in a return, there’s a possibility of a more permanent role. This becomes especially significant as NCIS bids farewell to all original characters in Season 21, leaving little hope for Gibbs’ return. However, DiNozzo’s reappearance creates an opportunity for a reunion with Gibbs, possibly in the franchise’s upcoming 1,000th episode celebration, offering fans a nostalgic moment in the show’s history.
