“Buck (Oliver Stark) is going to be spinning like a top by the time we come back,” 9-1-1showrunner Tim Minear told Decider when previewing the second half of the ABC drama series. He was referring to Buck’s realization that Eddie (Ryan Guzman) was moving to Texas to be closer to his son, meaning Buck would lose his best friend. “As soon as Eddie turns his back, Buck looks like he’s been hit in the head with a baseball bat, and that will figure in mightily when we come back,” Minear added. How much does it figure in? Stark told Today that he “was actually surprised” by the extent to which 9-1-1 will be exploring Buck’s complex feelings regarding his best friend. The actor talked to the outlet about his character’s arc in the second half, which begins airing on March 6.
