Oliver Stark’s Buck Is the Beating Heart of ‘9-1-1’ — And He’s Just Getting Started

   

From the moment Evan “Buck” Buckley ran into that first fire, fans of 9-1-1 knew they were watching something special. Portrayed by the talented and endlessly relatable Oliver Stark, Buck began his journey as a thrill-seeking firefighter with something to prove. But over the course of more than 100 episodes, he’s become the emotional anchor of Station 118.

Buck’s transformation has been one of the most rewarding arcs on the show — evolving from impulsive and immature to grounded, loyal, and brave in a whole new way. And at the center of his development has been his deepening bond with Captain Bobby Nash. What started as tension has grown into one of the show’s most profound relationships — a father-son dynamic built on mutual respect, hard lessons, and quiet loyalty.
