Brian Dietzen

Dietzen is the quiet MVP of the NCIS ensemble, and I have a real soft spot for how he grew Jimmy Palmer from a nervous, comic-relief autopsy assistant into one of the show's most quietly emotional anchors. That's a rare thing on network TV: a recurring side character who earns a full arc over two decades. The episode he co-wrote, dealing with Palmer's grief, was genuinely affecting and showed a creative ambition beyond just hitting his marks. He embodies the underrated value of the dependable supporting actor who makes a sprawling procedural feel like home. Steady, warm, and easy to root for.
