Brian Dietzen has reportedly shocked the NCIS fanbase by urging one of his longtime co-stars to step away from the series. Known for his calm and supportive presence both on-screen as Dr. Jimmy Palmer and off-screen among the cast, Dietzen’s bold move is raising eyebrows—and speculation. Insiders claim the conversation happened privately but has already had a ripple effect through the cast.

The co-star in question? None other than one of the show’s newer additions, whose presence has been met with mixed reactions from fans. While the identity hasn’t been officially confirmed, rumors are flying that tensions have been building behind the scenes over creative differences and the show’s evolving tone. Dietzen, a core member since season 1, reportedly feels that the series needs to “return to its roots”—and that may involve trimming the cast.

This revelation could explain recent awkwardness spotted during cast interviews and social media silence between certain team members. Some fans are backing Dietzen, saying he’s protecting the legacy of NCIS, while others are stunned that the usually reserved actor is taking such a public stand. One thing is clear: change is coming, and not everyone may survive the next season.

As filming for Season 23 heats up, all eyes are now on cast movements and official announcements. Could this be the start of a major shake-up for the beloved procedural drama? If Dietzen’s push gains traction, we might be saying goodbye to a familiar face very soon.
