Fans of Castle will know Dever as Detective Kevin Ryan, one-half of the series’ best non-romantic couple, along with his best friend and partner, Javier Esposito (played by Jon Huertas). In Tracker, Dever takes a bold detour from his law-abiding ways in his turn as the renegade and slightly traitorous Max Miller. A former soldier whose bad decisions have come back to track him down, Max is desperate, dangerous, and decisive. These traits make his character all the more unsettling, as his willingness to create havoc is fueled by fear. This character in crisis adds energy and serves as the perfect foil to Colter. Whereas the character of Colter Shaw is calm and reassuring, Max is a chaotic jolt of purpose that interrupts Colter’s day and enlivens the episode.
Max is a far cry from the goofy and mostly strait-laced character that Dever played in Castle. The closest comparison would be in Ryan’s short-lived arc of going undercover in the Irish mob. Although this was briefly explored in Castle (“The Wild Rover,” Season 5, Episode 18), his character in Tracker is reminiscent of Ryan’s brief sojourn on the other side of the law. A potential “what-if” had the storyline been explored more. His portrayal of Max is threatening and slightly unhinged, but he still manages to convey a compassionate figure. With Tracker, like in his previous role, Dever throws himself into the character with admirable assurance.
Seamus Dever, best known for his standout role as Detective Kevin Ryan on Castle, recently made a blink-and-you’ll-miss-it appearance in the new sci-fi drama Tracker. While his cameo had fans buzzing, it also left many asking, “Wait… was that really it?” This article dives deep into Dever’s short stint, why it was so brief, and whether we might see more of him in the Tracker universe.
