what happened to bobby on 911

On 9-1-1, Bobby Nash, played by Peter Krause, died in Season 8 after a biolab explosion exposed him and fellow firefighter Chimney to a deadly strain of Crimean-Congo Hemorrhagic Fever. Bobby's breathing apparatus was compromised during the rescue mission, which caused him to be fatally exposed to the virus. In a selfless act, Bobby used the only available antidote on Chimney, sacrificing his own chance of survival to save his friend. He spent his final moments saying goodbye to his wife Athena and his firefighter Buck before succumbing to the virus. His death was a creative decision by the show's producers to raise the stakes and keep the series emotionally impactful. Bobby's funeral was shown in the following episode, and the fire station was renamed in his honor.
