Taylor Kinney s portrayal of Severide has been a pivotal part of "Chicago Fire" since the show s debut in 2012, kickstarting the successful "One Chicago" franchise, including spinoffs "Chicago P.D." and "Chicago Med." With the showrunners and writers of these Chicago-set series back to work in early October, fans can look forward to the return of all three shows on NBC, although their comeback is expected to follow the SAG/AFTRA strike. In the meantime, viewers can catch up on the series by streaming them on Peacock.
