Why did Dean Miller die in ‘Station 19’? 

For viewers who missed Dean Miller’s shocking death, Station 19 Season 5 Episode 5 aired on Nov. 11, 2021. There was a massive explosion due to a ruptured gas line. A loose live electrical wire struck Vic Hughes (Barrett Doss) on the top of a ladder at the scene. Miller ran to her rescue and performed CPR. Once Vic is stable, the firefighters return to the explosion scene to check whether all of the houses were evacuated. 

Miller realizes that one of the houses might have gas building up inside it as Captain Aquino (Alain Uy) opens the door. Since the gas had no way to vent itself, the pressure rushed out in a massive explosion. It knocked down everything in its path, including Miller. The firefighters rushed to his side and immediately began CPR. Ben Warren (Jason George) and Jack Gibson (Grey Damon) performed CPR for 33 minutes to Grey Sloan Memorial Hospital. However, Miller was dead upon arrival in the first few minutes of the Grey’s Anatomy portion of the crossover event

Why did they kill off Dean Miller on ‘Station 19’? Onaodowan decided to leave

Showrunner Krista Vernoff explained in a recent interview that they killed Dean Miller off of Station 19 because actor Okieriete Onaodowan wanted to pursue new creative avenues.

“I am heartbroken by the loss of Dean Miller and that I no longer get to write for Oak,” Vernoff told TV Line. “Oak has an expansive spirit and was ready for and craving new artistic horizons — and I truly can’t wait to see what he does next. It will be powerful, it will be deep, and it will be courageous because Oak is all of those things.”

In the same interview, Onaodowan thanked his fans and expressed his gratitude for portraying Dean Miller on Station 19.
