For years, Jimmy Palmer was the quiet, awkward assistant in the autopsy room — but not anymore. Actor Brian Dietzen hasevolved Palmer into one of the most beloved and emotionally rich characters on NCIS, and fans have taken notice.
Since the tragic off-screen loss of his wife Breena (written into the show during the pandemic), Jimmy has grown from comic relief into one of the emotional backbones of the team. His deep empathy, quiet leadership, and loyalty have made him a fan favorite.
“Palmer is what we all need more of in 2025 — someone who listens, someone who heals,” one fan wrote on X.
Even more impressive: Brian Dietzen isn’t just acting — he’s writing episodes now, bringing even more heart and authenticity to the character. His recent co-written episode, focusing on Jimmy and Kasie trapped in a bioterror lab, was one of the most talked-about of the season.
With Gibbs gone and new faces joining the team, Dietzen has become one of the show’s most consistent and meaningful presences — and viewers are loving his rise.
