Spoilers ahead for Episode 9 of Chicago Fire Season 9, called “Double Red.“
Chicago Fire delivered a bad blow to Casey in “Double Red,” physically and perhaps also professionally depending on what happens next. He suffered a serious head injury while on the job, and longtime Fire fans will remember that this isn’t the first time Casey took a hard hit to the head. He was rushed to emergency surgery back in Season 2 when a beam fell on him, and it was clear even years ago that Casey’s noggin couldn’t be knocked too hard again. “Double Red” gave him that knock, and it’s one of the latest of several plot twist that lead me to wonder if Fire is setting Casey up to say goodbye.
