As the NCIS universe continues to expand, its newest iteration, NCIS: New York, is making sure to honor its roots right from the start. Collider reports that veteran actor Brian Dietzen will reprise his role as medical examiner Jimmy Palmer in the inaugural episode of the New York-based spin-off. Dietzen has been a mainstay on the original NCIS since its first season and has previously made crossover appearances in NCIS: New Orleans and NCIS: Hawai'i, making his inclusion a significant nod to the franchise's interconnected narrative.

His return for NCIS: New York underscores the show's intention to maintain strong ties with the broader NCIS continuity. The new series centers on LL COOL J's fan-favorite character, Sam Hanna, who relocates to the Big Apple following the conclusion of NCIS: Los Angeles. This move brings Hanna, a native New Yorker, back to his hometown for a fresh chapter of crime-solving. Showrunner Byron Balasco and star LL COOL J have both expressed enthusiasm for crossovers, hinting at the potential for more familiar faces down the line. Speaking to Deadline, LL COOL J stated, "I welcome crossovers. I think crossovers are great, and they’re fun." Balasco echoed this sentiment, adding, "We’ll have to see what happens. I mean, we’re all in the universe, so you can kind of expect anything like that to happen."

While details about Jimmy Palmer's specific role in the premiere remain under wraps, his presence is expected to provide an immediate connection for long-time fans. The pilot episode of NCIS: New York will see Sam Hanna investigating the tragic death of Navy reservist Jack Halloway. He'll receive authorization from Assistant Special Agent-In-Charge Robyn Wells, played by Jennifer Beals, to lead the investigation. Hanna will be joined by a new team of agents, including Wyatt Sellers (Shane Harper), Addy Ross (Jacqueline Byers), and computer expert Sean Sullivan (Devin Druid). Adding to the new dynamics, Scott Caan will join as Hanna's new partner, Nick Schaeffer. The series also benefits from the return of former NCIS: Los Angeles showrunner R. Scott Gemmill as an executive producer, ensuring a degree of continuity in tone and storytelling.

NCIS: New York is slated to premiere on October 6 on CBS, promising a new setting and fresh cases while keeping the spirit of the beloved franchise alive through its characters and potential crossovers.
