The latest installment of 9-1-1 Season 8 has left fans on edge with its intense two-part emergency storyline. Episode 14 ended with a cliffhanger, as beloved character Howard “Chimney” Han, played by Kenneth Choi, faces a life-threatening health crisis. Now, a gripping preview for Episode 15 has raised urgent questions about his fate.
What started as optimism for a successful rescue mission turned into dread after a 30-second teaser aired, revealing Chimney’s condition has taken a severe turn. In the promo, Maddie tearfully explains that Chimney has entered the second stage of exposure to the deadly infection, facing imminent organ failure. In a gut-wrenching moment, Chimney says to his teammates, “I’m running out of time.”
Fans were already concerned after Episode 14, where Chimney was seen coughing up blood and experiencing a nosebleed. Now, the escalating symptoms suggest the situation is far more critical than previously believed.

The trailer amplifies the tension, with visuals of chaos, blood, and Buck making a haunting prediction about retrieving only bodies from the scene. Hen’s emotional collapse and a firefighter falling beside a 118 helmet further fuel speculation—particularly whether Buck or Chimney may be the one lost.
Adding to the suspense, the narrator chillingly warns: “Think you know the ending? You’re dead wrong.”
However, a sliver of hope remains. A brief shot in the preview shows Bobby stating that Athena is on her way with the antiviral, suggesting Chimney might still have a chance at survival.
While the series is no stranger to dramatic misdirection, fans will have to wait for the next episode to find out who survives and who may not make it out.
