With the death of David McCallum’s Ducky, NCIS season 21 marked the end of an era, as no original characters remained active members of the Major Case Response Team. Over the years, the original team members have left for various reasons, resulting in a shifting ensemble cast typical of long-running television shows.
Among these exits, Special Agent Kate Todd’s death stands out as particularly shocking and cruel, marked by her dramatic assassination at the hands of Ari, Ziva’s half-brother. With Ari’s introduction, Kate’s demise seemed almost inevitable.
Unlike some other departures from the show, Sasha Alexander’s decision to leave NCIS did not involve behind-the-scenes drama. Her exit, unlike Pauley Perrette’s later contentious departure, was amicable. Alexander chose to leave due to the grueling filming schedule required for the 24-episode seasons, which heavily featured her and the core cast. Despite the brutal way her character was written out, it was Alexander’s own decision to end Kate’s arc.
Alexander’s departure highlighted the demanding nature of the job, a sentiment echoed by Mark Harmon, who cited similar reasons for retiring his legendary character, Gibbs. Alexander’s enduring friendship with co-star Michael Weatherly further demonstrates that her departure was free of any off-screen dispute.
NCIS has become adept at managing the departures and arrivals of cast members, maintaining its appeal and longevity despite these changes. Kate Todd’s death remains one of the most memorable moments in the show’s history, underscoring the unpredictable and often harsh realities faced by the beloved characters.
