who plays severide's parents on chicago fire
Kelly Severide The son of CFD Captain Benny Severide (Treat Williams), Kelly was raised singlehandedly by his mother, Jennifer Sheridan (Kim Delaney), after Benny left the family when Kelly was in elementary school. Although Kelly has since reconnected with his father, they still share a love-hate relationship. He is often known to the "white shirts" (high-ranking officers) as Benny's son[2][1] but never used his father's name to advance his career, instead carving out his own reputation as a highly competent firefighter.
