Although not a member of Station 19, Lieutenant Cooper's death will have repercussions for the squad.

In Season 6, Episode 10 titled "Even Better Than the Real Thing," Station 19 was having a training day with the firefighters from Station 88 when an explosion went off unexpectedly.

Cooper, played by actor Johnny Wactor, died from his injuries — and many placed the blame on Sean Beckett (Josh Randall), who has been struggling with his sobriety.

Following Cooper's death, Andy and the rest of the Station 19 team have lost faith in Beckett, who recently replaced Maya as Captain. There is also an ongoing investigation into Cooper's death, so Beckett's future as a firefighter is also up in the air.

"Cooper died because of Beckett's negligence," Lieutenant Theo Ruiz said on the show. "If any of us follow Beckett into a fire, joke's on us."
