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.
