A long-awaited character evolution for Buck in 9-1-1 season 9 is poised to fundamentally alter the 118. As unpopular as the decision to kill off Captain Bobby Nash (Peter Krause) has been, the immediate question that has followed in its aftermath is what his absence actually means for those he left behind.
In the 9-1-1 season 8 finale, that question was addressed from a collective perspective. The episode examined who would take over as the 118’s new leader, pointing to Howard “Chimney” Han (Kenneth Choi) as Bobby’s reluctant successor. It also suggested that Bobby’s widow, Athena (Angela Bassett), will begin to take her first steps forward after an unquestionably devastating loss.
But there are larger questions about what the ABC first responder drama and its main characters will look like when new episodes debut this fall. New comments from original cast member Oliver Stark, who plays Evan Buckley, suggest a significant shift that has been rumbling for quite some time.
For years, Evan “Buck” Buckley has been the beating heart of the 9-1-1 team. He’s wild, he’s brave, he’s sometimes a mess—but he’s always there when it counts. And yet, since Season 1, fans have been waiting for that one big shift in Buck’s character that would elevate him from lovable hothead to mature leader. Well, the wait is over. Season 9 of 9-1-1 finally delivers Buck’s long-teased evolution, and it’s going to rock the 118 like never before.
