In a poignant tribute to Ducky Mallard in NCIS season 21, the show subtly nods to its best team era through a discovery in a secret vault. Despite cast changes, NCIS remains CBS’ longest-running scripted series. The ensemble of Gibbs, DiNozzo, McGee, Palmer, Ziva, Abby, Vance, and Ducky is hinted as the show’s strongest lineup, with their photo found in the safe during McGee and Alden Parker’s investigation into Ducky’s final case. This iteration, marked by enduring camaraderie and compelling storytelling, represents the pinnacle of NCIS’ success, blending romance, personal histories, and dynamic teamwork.
