Jesse Spencer has landed his first role after exiting Chicago Fire, and it couldn’t be any more different than Matt Casey. Casey was a fixture at Firehouse 51 for the first 11 seasons, where his PTSD-related challenges made him one of Chicago Fire’s best characters. He experienced the deaths of people close to him on top of overcoming a traumatic childhood and had two significant but ultimately heartbreaking relationships before he began dating Sylvie Brett, who he had a happy ending with before the two left for Oregon together.
