The fall finales of the One Chicago franchise all focus on characters who consider themselves outsiders. Dr. Dean Archer (Steven Weber) in Chicago Med, Chief Dom Pascal (Dermot Mulroney) and paramedic Lizzie Novak (Jocelyn Hudon) in Chicago Fire, and Officer Dante Torres (Benjamin Levy Aguilar) in Chicago P.D. all encounter a common issue when it comes to balancing personal dilemmas and their work. These characters are morally conflicted because they struggle to distinguish between their past struggles and current occupations.
