After months of silence and speculation, NBC has finally broken the suspense: Chicago Fire, Chicago P.D., and Chicago Med officially return this fall — and fans are already bracing themselves. But while the return date is now confirmed, the real mystery is who might be returning with it.
According to NBC’s latest release, One Chicago’s trio of shows will premiere on Wednesday, October 2, 2025 — a lineup that promises to “reset everything fans thought they knew.”
But buried within the press statement is something far more intriguing:
“This season, One Chicago revisits unfinished stories, long-lost relationships, and a few surprise faces from the past.”
Naturally, fans are already spiraling.
Could this mean the return of Matt Casey in Chicago Fire — permanently this time? His surprise reappearance last season already shook things up. But now that Sylvie Brett is gone, would Casey stay in Chicago… or is there another reason NBC is teasing his name?
And then there’s Chicago P.D.. After Jay Halstead’s sudden departure to Bolivia, viewers were devastated. But new reports suggest Jesse Lee Soffer — who’s since stepped behind the camera — may return to direct and star in a special arc. Could Halstead’s off-screen mission finally be revealed?
Meanwhile, Chicago Med fans are clinging to hope that Dr. Connor Rhodes — played by Colin Donnell — could return for a medical emergency too big for the current team. After all, the show teased a mysterious transplant storyline in the upcoming season that might require “outside help.”
So why the secrecy?
Insiders say NBC is deliberately hiding key cast reveals to build suspense — and with good reason. Over the years, surprise returns (like Casey’s) have led to spikes in ratings and social media frenzy. This time, they’re doubling down.
And here’s where it gets even more curious:
An updated NBC filming calendar shows several former cast members with “tentative guest days” scheduled during shooting weeks in August and September. Their names? Redacted.
Are these classic actors returning for nostalgia — or are we looking at full-blown reintegration into the core cast?
NBC’s return date announcement came with a short teaser clip that shows firefighters running into a smoky building, a surgeon staring at a monitor, and a detective shouting “I thought you were gone!” — without showing any faces. Within hours, the fandom exploded with theories.
Could that line be directed at Halstead? At Casey? Or someone nobody expects?
What’s clear is this:
NBC isn’t just bringing One Chicago back — they’re reigniting it with secrets.
The only question left is…
Are fans really ready for who’s coming back with them?
