Chicago Fire: Season 13 Brings Heat and Heart

Big Returns and Even Bigger Exits

Stella Kidd and Kelly Severide are at the center of Firehouse 51 once again. After some time apart (and off-screen drama), it looks like the couple will face new challenges—professionally and personally.

But that’s not all. Some familiar faces will return, while others may bow out for good. Is this the last we see of Chief Boden? Rumors are swirling, and fans are holding their breath.
