Spoilers ahead for Episode 3 of Chicago Fire Season 12, called "Trapped."
The heroes of Firehouse 51 were doing more than just fighting the usual fires in Chicago Fire's newest episode, with Brett and Violet using their ambulance to chase down a man who had abducted a woman. Meanwhile, Severide was itching to play fire cop again and investigate an arson case in Tucscon, to the dismay of Stella after what happened last time. That would have meant leaving Squad 3 in Cruz's hands again, which has been a touchy subject in Season 12. After "Trapped," another character took their leave from Firehouse 51 not too long after Gallo, while Violet's story is heating up in the 2024 TV schedule.
