In his final words to Buck, in the wrenching closing minutes of the 9-1-1 episode “Lab Rats”, Bobby tells Buck that he can handle the sudden loss. It’s a show of faith in the young firefighter, even though he hasn’t always deserved it. Early on in the procedural drama, though his heart and good-natured attitude were clear from the outset, he was the least emotionally mature of his 118 peers. His cohorts had fun with this fact. Henrietta (Aisha Hinds) and Howard, in particular, would tease him in his more dim-witted moments. Eddie (Ryan Guzman) would more or less accept Buck the way that he is, except for the instances in which he would lose his patience with Buck’s shortsighted impulsiveness. These moments continued to play out in 9-1-1 season 8, with Eddie directly calling out Buck.
“The trials and tribulations of Evan Buckley, a tragedy in 97 acts,” Eddie scoffs mockingly, during the 9-1-1 season 8 episode “Don’t Drink the Water.” It’s a very recent episode, which highlights the fact that Buck still tends to indulge in his worst impulses. Despite this, he can also be incredibly heroic and remarkably giving. The character is layered, adjusting from one side to the other depending on what the story requires. It’s a characterization that also, conveniently, kept Buck as the little brother of 9-1-1. He is Maddie’s little brother, of course, but he also occupies that role more broadly for the 118. They love him and see the best in him despite his occasional blunders. If that aspect fades further, then it would truly shift the 118.
When we first met Buck on 9-1-1, he was that wild, thrill-seeking rookie with a heart too big for his own good. But somewhere along the way—through heartbreaks, losses, and near-death experiences—Buck started to grow up. And now? He’s not just changing himself—he’s reshaping the entire vibe of the 118 firehouse.
So, what happens when the fun-loving chaos agent becomes the grounding force of the team? Let’s dive into how Buck’s maturity is shaking things up in the most unexpected and exciting ways.

Remember Season 1 Buck? He was the textbook definition of reckless. Sleeping around, partying too hard, and diving headfirst into danger without a second thought. Charming? Sure. Responsible? Not even close.

Every hero needs their crucible. For Buck, it was a series of hard-hitting wake-up calls:
-
Abby leaving him

Each moment added a layer of depth—and pain—that forced Buck to stop running and start reflecting.
