Hey there, fellow One Chicago fans! It’s Marie here, your go-to source for the latest buzz from the Windy City. If you thought the drama was confined to the screen, think again. The One Chicago franchise has been stirring up quite a storm behind the scenes lately. From unexpected exits to surprise returns, here’s a rundown of the most talked-about changes.
Tracy Spiridakos Bids Farewell to Chicago P.D.

In a move that rocked the Chicago P.D. fanbase, Tracy Spiridakos, who played Detective Hailey Upton, announced her departure after seven seasons. The actress shared that her decision was deeply personal, as she wanted to explore new opportunities and challenges outside of the long-running police drama.
Her exit came in a dramatic season 11 finale, where Upton made a heroic rescue before deciding to step away from the Intelligence Unit. Fans were left heartbroken but also appreciative of Spiridakos’ impact on the show.
4️⃣ Shocking Cameo in Chicago P.D. Season Finale

The season 11 finale of Chicago P.D. threw fans for a loop with a cameo that no one saw coming. In a heartwrenching moment, Detective Hank Voight (played by Jason Beghe) experienced a hallucination of his former partner, Detective Alvin Olinsky (Elias Koteas), who was tragically killed off in season 5.
The return of Olinsky’s character, even in this ghostly form, was an emotional tribute to the show’s past and added a layer of sentiment to Spiridakos’ exit, leaving fans wanting more of the emotional depth they had witnessed.
3️⃣ Chicago Med Welcomes Back Original Cast Members Amidst Behind-the-Scenes Changes
Chicago Med is also experiencing some major shake-ups behind the camera, but at least fans can take comfort in the fact that the original cast members are sticking around.
S. Epatha Merkerson, Oliver Platt, and Marlyne Barrett have all re-signed contracts to continue their roles, ensuring that the heart of the show remains intact. But things are changing at the top, with new showrunner Allen MacDonald stepping in after the departure of Diane Frolov and Andrew Schneider. Fans will need to keep an eye on how these behind-the-scenes shifts impact the direction of the beloved medical drama.
2️⃣ Dominic Rains Exits Chicago Med After Five Seasons
Dominic Rains, who has portrayed Dr. Crockett Marcel on Chicago Med for five seasons, is leaving the show. His exit was hinted at during the season 9 finale, when a traumatic event led his character to take some time off. Although Rains is moving on, viewers can still expect to see Jessy Schram, Steven Weber, and Luke Mitchell return alongside the original cast members, which should provide some continuity.
1️⃣ Major Cast Departures Shake Up Chicago Fire

Chicago Fire has also been rocked by cast changes, as some fan-favorite characters are saying goodbye. Eamonn Walker, who portrayed Battalion Chief Wallace Boden, made his exit during season 12. Along with Walker, Alberto Rosende, who played firefighter Blake Gallo, also left the show after the season 12 premiere.
These departures come on the heels of other notable exits, including Kara Killmer and Rome Flynn. With so many key players leaving, fans are left wondering what direction the show will take, and whether the drama can survive without some of its most iconic characters.
