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.
