Chicago Fire actor Dermot Mulroney has spoken about his exit from the show following the announcement of his departure after two seasons of playing Battalion Chief Dom Pascal. The star made his debut on the show in season 13, with his exit confirmed after the season 14 finale aired. That episode ended on a cliffhanger, with Pascal included in the first episode of season 15 only, in order to conclude the storyline. Speaking at the Flashback Weekend fan convention in Chicago last week (via Entertainment Weekly), Mulroney spoke about leaving the show and explained that the decision wasn't his. Now that he's filmed his final Chicago Fire appearance, Mulroney said that he's "sad to see it go".
