Summary

• Due to cast changes, a 2024 One Chicago crossover is necessary.
• Each One Chicago show has had significant cast exits in previous seasons.
• There has been a lack of crossovers due to safety concerns regarding COVID-19.

The the short-lived Chicago Justice came, and although Chicago Justice is gone, the other shows are alive and thriving.

The One Chicago TV shows premiere on Wednesday, September 25, on NBC, with Chicago Med season 10 premiering at 8 p.m. ET, Chicago Fire season 13 at 9 p.m. ET, and Chicago PD season 12 at 10 p.m. ET.

Over the course of the One Chicago universe, there have been three crossovers including the three main series (Chicago Fire, Chicago PD, and Chicago Med). Of course, NBC has released numerous other smaller crossovers that only include two shows, with Law & Order: SVU even getting into the mix occasionally. However, the last time the three primary TV shows connected was in October 2019. The crossover was called "Infection" and focused on a bioterrorism attack in Chicago, and, unfortunately, the network hasn't planned another crossover since then.

One Chicago's Cast Changes Makes A 2024 Crossover Necessary

Each One Chicago TV Show Featured At Least 1 Significant Exit During Their Previous Seasons

It has been five years since Chicago Fire, Chicago PD, and Chicago Med teamed up, and consequently, each show's cast looks different. Matt Casey, Sylvie Brett, and Chief Boden have left Chicago Fire, while new characters like Violet Mikami, Sam Carver, Lyla Novak, and Dom Pascal have ed or will . As for Chicago PD, Jay Halstead and Hailey Upton exited, and Dante Torres and Kiana Cook are now a part of the crew. Finally, Will Halstead, April Sexton, Natalie Manning, Ethan Choi, and Crockett Marcel left Chicago Med, while Dean Archer, Hannah Asher, and Mitch Ripley now work at Med.

Given that each cast of One Chicago desperately needs a crossover in 2024, it likely won't happen.

NBC's Reason For The Lack Of One Chicago Crossovers Can Easily Be Addressed

Safety Was NBC's Previous Concern

The One Chicago franchise hasn't had a crossover in five years because of the COVID-19 pandemic. Concern for the cast and crew's safety was the main reason, which made sense in the early 2020s and should be the top priority. But now that some time has ed, many have gotten accustomed to a "new normal," so, it shouldn't be difficult for NBC to concoct a crossover. Unfortunately, a One Chicago crossover event doesn't seem to be in the cards for the 2024–2025 season as COVID protocols are still in place.
