Chicago Fire season 13 has officially found its Chief Wallace Boden replacement in Firehouse 51. Eammon Walker was the very first actor cast when Dick Wolf and NBC decided to expand the producer’s TV franchise to the Windy City. Unlike the departures of Blake Gallo and Sylvie Brett, Boden’s departure in the Chicago Fire season 12 finale was announced towards the year’s end, surprising many fans. However, work for Firehouse 51 continues. Instead of following Boden’s plan, which was to make Christopher Hermann his replacement, Wolf Entertainment is going a different route.
