Bring back: Mouch
We know he’s technically not dead, but things look dire for the Firehouse 51 veteran. His pulse is weakening, and last we saw of him, he had soaked the sheets of his hospital with his blood. The show has a tendency of teasing major deaths in the past, but the fact that characters like Otis has died in season premieres means we have to take this latest threat seriously.
It’s tough to imagine Chicago Fire without Mouch. He’s been there since the beginning, and if we had our way, he’d continue to stick around.
Leave be: Hallie Thomas
We have nothing against Hallie Thomas (Teri Reeves). She breaks up with Casey in the pilot, and they reconcile a few episodes later, but we simply don’t get enough time with her to get a feel for who she is and what makes her the ideal partner for Casey.
We were horrified when she was murdered at the tail end of the season, but bringing her back would mean that we wouldn’t get to see Casey’s relationships with Gabby (Monica Raymund) and Brett (Kara Killmer) play out, which would be tremendous losses to the show.
