9-1-1 Officially Confirms a Season 10 Buck Replacement Through Harry’s First Loss

Buck’s growth at the 118
Across 10 seasons, Buck’s development has been one of 9-1-1’s rewarding storylines. Oliver Stark’s character began as a probie in the pilot, confident without having earned it, careless with rules and prone to acting on impulse.
His relationships with the 118 and his experiences on the job helped him mature. Buck became a more assured firefighter who treats his work with care.
Harry faces a defining loss
Season 10 is only two episodes in, but the show has already positioned Harry Grant as a new counterpart to Buck’s younger self. In Episode 2, “Fire in the Hole,” Harry experiences his first loss while working, a moment that may stay with him as Buck’s first loss did in season 1.
Harry, played by Elijah M. Cooper, joined the 118 after growing up in a family of first responders. Bobby’s death also shaped his entry into the job, giving him respect for its risks from the outset.
A reckless move echoes Buck
In season 9, Harry wanted Chimney to give him more responsibility at the 118. He was frustrated that he could not immediately join the action, but remained determined to earn his way forward.
The season 10 premiere gave Harry a moment resembling Buck’s impulsive behavior. When Harry’s weight prevented the 118 from pulling a victim out of a sinkhole, he jumped off, putting himself in danger.
