Chicago Fire EP says one character is not coming back — and we are not okay

It’s been an exceptionally long summer for Chicago Fire fans, but fall is finally here. Thursday night’s season 6 premiere will pick up right where that devastating spring cliffhanger left off — with several characters in serious peril in the middle of a massive warehouse fire.

That’s right, we’ll finally know for sure if Casey’s (Jesse Spencer) weeper of a “you’re my miracle” speech to Gabby (Monica Raymund) was a true goodbye and if Mouch (Christian Stolte) is really retiring… or retired for good.
