Viewers will meet Wallace Boden’s replacement when Chicago Fire season 13 premieres in September 2024, and the new fire chief is expected to be very different from the former one, which is a great sign for the show. Boden has served as the leader of Firehouse 51 in the NBC procedural drama TV series since season 1. Sadly, Eamonn Walker left Chicago Fire ahead of season 13, and someone has to take his place. Some speculated that Boden’s successor would come from in-house, and Christopher Herrmann would become Firehouse 51’s chief, but that won’t be the case.
