Dom Pascal, Chief Wallace Boden’s replacement in Chicago Fire season 13, immediately rubs Firehouse 51 the wrong way, and there’s a good reason for that. Eammon Walker left the franchise in the Chicago Fire season 12 finale. By then, Firehouse 51 had already lost several key members of the team, such as Blake Gallo and Sylvie Brett. That said, considering the impact that Boden has had in the show, his exit was Chicago Fire‘s biggest loss. Luckily for the character, however, he was given a happy send-off, as Boden left Firehouse 51 for a much bigger role in the CFD.
