Chicago Fire Boss Teases 'Uncharted Territory' for Stellaride in Season 9
Chicago Fire returns this Wednesday and we couldn't be happier to see Firehouse 51 back in action! The new season will see several changes, like Ritter getting more screentime and Gianna Mackey boarding Ambulance 61 as Brett's (Kara Killmer) new partner following Foster's (Annie Ilonzeh) departure. While we don't know much about Mackey, Fire showrunner Derek Haas did drop some key details about the incoming paramedic."Mackey is friends with Joe Cruz (Joe Minoso) before she ever comes to the firehouse," Haas told TV Guide via email, adding that she's known Cruz since she was a child.
