9-1-1’s Evan “Buck” Buckley and Eddie Diaz have captured the hearts of fans since they first appeared together in the second season, with many speculating about the potential for their friendship to develop into something deeper.
Buck and Eddie, portrayed by Oliver Stark and Ryan Guzman, quickly formed a strong bond after Eddie joined the 118 in season 2. Their friendship was solidified when Buck selflessly prioritized the safety of Eddie’s son, Christopher (Gavin McHugh), during a catastrophic earthquake in Los Angeles. Stark believes this pivotal moment marked the beginning of their meaningful connection.
“In the aftermath, we [see] Buck driving Eddie to pick up Christopher,” Stark revealed in an exclusive interview with Us Weekly in 2022. “That gesture signified a lot. Despite having a car, Eddie chose to rely on Buck, who wanted to genuinely extend a hand. This moment clearly illustrated their willingness to engage in each other’s lives moving forward.”
As the series progressed through six seasons, the duo continued to support one another through various personal and professional challenges, with Buck even taking on a second fatherly role for Christopher. Their mutual struggles in finding long-term romantic partners have stoked rumors that they could share an even deeper bond.
Stark attributes the popularity of the duo to their “fun energy,” which is complemented by a profound understanding of each other. “They have woven themselves into each other’s lives which has allowed them to connect on multiple levels, whether in personal or work scenarios. This charming mix seems to be a great foundation for their relationship, regardless of how you define it,” he stated.
