One Chicago Season Finales Are Here: Drama, Suspense, and Shocking Twists Ahead!

One Chicago Wednesdays for the 2024-2025 season will end with a bang on NBC. After three new seasons full of action-packed episodes, the finales for Chicago Fire, Chicago P.D., and Chicago Med will all air in May 2025.

In Chicago Fire's universe, Kelly Severide (Taylor Kinney) and Stella Kidd (Miranda Rae Mayo) have gotten some exciting baby news in Season 13, while the dedicated doctors and nurses at Gaffney on Chicago Med have been put through the wringer throughout Season 10. And in between fighting the Windy City's most sinister and harrowing cases, Kim Burgess (Marina Squerciati) and Adam Ruzek (Patrick John Flueger) will finally tie the knot in Season 12's Chicago P.D. finale. And just like One Chicago's fans, Squerciati said she's "stupidly excited" for their TV wedding.

Not only is this exciting news for Chi-Hards, but One Chicago’s cast and crew will continue to be a close-knit bunch. In a November 2024 interview with NBC Insider, David Eigenberg, Chicago Fire’s Christopher Herrmann, said there’s really never a dull moment on set. “We have laughed hard. We laugh hard every day on this show,” Eigenberg said. “That’s why the crew has stayed. Everybody that could possibly stay stays because it's a beautiful set.”

And when fan-favorites have left but get to return for a sweet reunion, it’s always exciting. Eamonn Walker, Chicago Fire’s Chief Wallace Boden (whose Season 12 exit as a series regular shook One Chicago's devoted fanbase), told NBC Insider in April 2025 that returning to Firehouse 51 in Season 13, Episode 18 ("Post Mortem") was “very emotional.”

“It was amazing. I had a wonderful time. I had missed everybody. They had missed me. And so the coming together was very emotional,” Walker said, going on to describe his Chicago Fire cast-mates as “family.”

“It’s my family. It's my extended family,” he added. “Getting them back in my life and being able to laugh and joke and work and connect was everything that my inner being had been missing in the time I'd been away. And it was like a jolt to my spirit. I was very, very happy to be back, and I would have to say that the welcoming was amazing, too. They welcomed me home.”
