After 9-1-1 season 8's tragic death, the upcoming episode is poised to be devastating. 9-1-1 season 8, episode 15, "Lab Rats" saw the 118 fighting an uncontrolled lab leak, and it ended with a genuine tragedy. Chimney (Howie Han) was infected with the Crimean-Congo hemorrhagic fever, and the 118 was able to find an antidote to save him, but there was no chance to save the similarly infected Bobby (Peter Krause). Bobby died at the end of the episode, marking the end of an original member of the 118, which is a significant change for the show.
