- Alberto Rosende is leaving Chicago Fire after four years of playing character Blake Gallo. His final appearance will be in the 12th season premiere. I'm so behind on Chicago Fire, I need to get caught up. Alberto Rosende is not the only cast member to announce they are leaving the show. It's starting to feel like the show is having a high turnover rate and it might be time for the show to end. Anyway, sad to see Alberto go but I hope his next project will be something interesting as well.
