Watson Adds NCIS: Hawai’i Star to Growing Season 2 Cast
Introduction: A Casting Move That Has Fans Talking
CBS has been building serious momentum with Watson, its fresh medical-mystery drama centered on the iconic Dr. John H. Watson from the Sherlock Holmes universe. The first season surprised audiences with a modern twist on crime-solving, giving Watson center stage after Holmes’ presumed death. As Season 2 gears up, CBS has dropped a casting surprise that’s shaking up fan communities everywhere: a major NCIS: Hawai’i star is officially joining the series. This article dives deep into what this casting choice means, why it’s already generating buzz, and how it might reshape the upcoming season.
Watson Season 2 Gets a Big Boost With NCIS: Hawai’i Talent
A Strategic Move From CBS
CBS has a habit of strategically moving stars between its biggest franchises to strengthen new shows. With NCIS: Hawai’i ending earlier than expected, the network is taking full advantage of its extremely talented cast — and Watson is now benefiting in a major way.
Bringing a recognizable, adored actor from a successful crime procedural is a smart play. It instantly boosts hype, brings built-in fans, and gives the show an energy injection for its sophomore season.
Why This Casting Matters for Watson’s Future
Season 1 proved Watson could stand on its own. But Season 2? That’s where CBS must cement the show’s long-term staying power. A high-profile cast addition signals confidence, investment, and commitment.

How the New Cast Member Could Fit Into Watson’s World
