Find out when all your favorite One Chicago series return on NBC and stream episodes on Peacock.

It was announced on July 25 that the star would be joining the Chicago Fire cast for Season 13.

Chief Boden left Firehouse 51 at the end of Chicago Fire Season 12 — but does this mean Walker has exited, too? 

Boden was Firehouse 51's fearless commander for years and a bona fide Chi-Hard fan favorite.

Boden needed someone with tenure, passion, and heart to fill his shoes. And he found the perfect candidate. 

It's not every day that you discover an estranged brother, let alone one who has become your coworker.

Boden decided to take a job elsewhere in the CFD. Here's why the character made this move. 

Chicago Fire showrunner Andrea Newman means this figuratively, of course, but that still doesn't bode well for the fan-favorite couple. 

NBC Insider spoke with co-executive producer Demetra Diamantopoulos to get the scoop on filming locations.

Between the political turmoil, firehouse exits, and family drama, Boden is staring down an unclear future at 51.
