It’s no secret that Kelly Severide didn’t have the best relationship with his father, Benny, in Chicago Fire, but one would think Benny would stop haunting Severide’s life after his death. Unfortunately, for Severide, someone showed up at Firehouse 51 during season 12 who makes it impossible for Benny to quit sabotaging him — Jack Damon, Benny’s son and Severide’s half-brother. Damon is the brother who Severide never thought he had. While exciting at first, Damon is proving to be more of a nuisance for Severide in Chicago Fire season 13 than an asset and confidant.
Benny, played by Treat Williams, died in Chicago Fire season 7, episode 6, “All the Proof,” which aired in October 2018. However, Williams’ last appearance was in episode 5, “A Volatile Mixture.” During episode 6, Severide and Damon’s father suffered a stroke and died. Despite Benny’s absence from the NBC procedural drama TV show, Severide can’t seem to shake his father and his past, as seen in Chicago Fire season 13, episode 2, “Ride the Blade.”
