They killed off Bobby Nash on 9-1-1 as a creative decision by the show's showrunner Tim Minear to shake things up for the 118 fire team and raise the stakes for the other characters. Bobby's death marked the first major character loss on the show and was intended to create a tonal shift, challenging the characters and storylines moving forward. Specifically, Bobby sacrificed himself after being infected by a deadly virus in order to save his team, showing his selflessness and leadership. This narrative choice was meant to honor the bravery of first responders while also intensifying the drama of the series. The decision was not motivated by budget or actor Peter Krause’s wishes, but rather by a deliberate storytelling choice to give a powerful, emotional impact and to explore how the characters cope without him. Minear had to convince the network at high levels to approve the death scene due to its significance.
