The highly anticipated One Chicago crossover event is finally here, and it will feature the returns of Jesse Lee Soffer as Jay Halstead and Tracy Spiridakos as Hailey Upton. After Halstead's abrupt exit from Chicago P.D. in 2022, the showrunners saw the crossover as an opportunity to give the former couple more time on screen together and a chance to complete their story in a meaningful way.
Why it matters
Halstead's departure from the show was controversial, leaving many fans unsatisfied with how his relationship with Upton was left. The crossover allows the writers to address this and provide some closure for the popular 'Upstead' couple.
The details
In the crossover, a crisis at an airfield brings the heroes of all three One Chicago shows together, including Halstead and Upton. The showrunners say they weren't necessarily trying to 'redeem' Halstead, but rather to show how he has changed since his exit and to have him take responsibility for some of his past actions. The crossover will feature substantial screen time for Halstead and Upton as they navigate their complicated relationship.
- The One Chicago crossover event will air on March 4, 2026.
- Halstead left Chicago P.D. in 2022.
The players
Jay Halstead

What they’re saying
“For me, it was a chance to have more time with him, to have an ability to have basically three more hours with this character, and to have him on screen with Upton again, because of the way that each of these characters left. They didn't get to leave together. They didn't get to have sort of these scenes on screen that I think would have felt really cathartic, and felt really like they were completing some sort of story they had together.”

What’s next
The crossover event will air across the three One Chicago shows on March 4, 2026, with Chicago Fire kicking things off, followed by Chicago Med and then concluding with Chicago P.D.
The takeaway
The One Chicago crossover provides a much-needed opportunity to give Halstead and Upton's relationship the proper closure and resolution that fans have been craving since Halstead's abrupt departure from the show in 2022.
