Fresh set photos from Chicago P.D. have just delivered the reunion fans have been begging for — and it’s bigger than anyone expected. For the first time in years, Jesse Lee Soffer and Tracy Spiridakos are back together on set as Jay Halstead and Hailey Upton. And yes, Upstead is officially back in the building.
When Spiridakos exited the series in season 11, many fans feared they would never see Halstead and Upton share the screen again. The couple’s story felt unfinished, their goodbye lacking the emotional closure viewers had hoped for. Since Halstead’s departure in 2022, the door seemed firmly closed. There were no subtle hints in recent episodes, no narrative breadcrumbs, and no credible leaks suggesting a return. That’s what made NBC’s announcement of the 2026 One Chicago crossover event such a jaw-dropping moment.
Out of nowhere, the network confirmed that both Upton and Halstead would return for the massive crossover. It was the kind of twist that sends shockwaves through a fandom — completely unexpected and thrillingly bold. In an era where spoilers are nearly impossible to avoid, the production somehow managed to keep this secret airtight. No blurry set photos. No cryptic cast teases. Nothing. Until now.
With the surprise finally revealed, the cast has wasted no time fueling the excitement. The first behind-the-scenes tease came courtesy of Marina Squerciati, who shared a joyful group photo from the set. The snapshot featured Spiridakos alongside Squerciati and fellow cast members Benjamin Levy Aguilar and Arienne Mandi. Squerciati captioned the image with a playful nod to the show’s typically intense tone: “Yes, we do smile (just not on the show, but we are capable).”
That single photo was enough to send fans into a frenzy. Seeing Spiridakos back among her castmates instantly reignited excitement for what promises to be one of the most ambitious crossover events in One Chicago history. And while the image didn’t reveal any plot details, it confirmed what matters most — Halstead and Upton will once again occupy the same space.
The timing couldn’t be more perfect. The One Chicago universe — spanning Chicago Fire, Chicago Med, and Chicago P.D. — thrives on high-stakes storytelling and emotional character arcs. Bringing back two beloved characters with unresolved history guarantees powerful drama. Whether the crossover focuses on a citywide crisis, a deeply personal case, or something that forces Halstead and Upton to confront their past, the emotional weight is already built in.
What makes this reunion especially compelling is the growth both characters have undergone separately. Upton’s journey in season 11 was defined by resilience and self-reflection, while Halstead’s absence loomed large over the Intelligence Unit. Their dynamic was always layered — professional partners, romantic partners, and at times emotional anchors for one another. Reuniting them opens the door to closure, reconciliation, or perhaps an entirely new chapter.
For fans who felt robbed of a proper farewell, this crossover feels like redemption. It’s not just a cameo. It’s not a fleeting mention. It’s a full-circle moment years in the making.
One thing is certain: when Halstead and Upton finally share the screen again, it won’t just be another episode of Chicago P.D. It will be an event. And judging by the cast’s infectious excitement behind the scenes, the reunion is going to be every bit as epic as fans have imagined.
