The One Chicago universe is known for its epic crossovers, but the 2025 event is shaping up to be one of the most memorable yet—especially for fans of Chicago P.D.. Not only will this highly anticipated event bring together characters from Chicago Fire, Chicago Med, and Chicago P.D., but it will also set the stage for a long-awaited moment: the wedding of Kim Burgess and Adam Ruzek. Adding to the excitement, the crossover will introduce two special cameos that promise to make their big day even more unforgettable.
Burgess & Ruzek: A Love Story Years in the Making
For years, fans have been rooting for Burzek to finally make it down the aisle. Their relationship has been a rollercoaster of emotions, filled with breakups, reconciliations, and life-or-death situations that have only made them stronger. After everything they’ve been through—including raising Makayla together—it’s only fitting that their wedding is set to be a major event in the One Chicago universe.
While details about the ceremony have been kept under wraps, the latest crossover has just revealed that two very special guests will be in attendance.
Who Are the Two Special Cameos?
Although NBC has yet to make an official announcement, inside sources suggest that the two surprise guests will be familiar faces from the One Chicago universe. Here are the most likely candidates:
-
Erin Lindsay (Sophia Bush) – A fan-favorite from the early seasons of Chicago P.D., Lindsay was once a close friend and mentor to Burgess. Her return for the wedding would be a touching full-circle moment, especially considering how much Burgess has grown as an officer and a person. Given that Lindsay left Chicago to work with the FBI, it would be fascinating to see what brings her back—and whether she still keeps in touch with her old Intelligence family.
-
Alvin Olinsky (Elias Koteas) – In Flashback Form – While Olinsky tragically died in Season 5, his impact on Intelligence—and especially on Ruzek—was profound. Rumors suggest that the wedding could feature a flashback scene or a heartfelt tribute that brings Olinsky back in some form, reminding Ruzek of the wisdom and guidance his former mentor once gave him. If this happens, it would be a deeply emotional moment for both Ruzek and the audience.
How the Crossover Sets Up the Wedding
The One Chicago crossover is expected to revolve around a high-stakes emergency that brings together members of Chicago Fire, Chicago Med, and Chicago P.D.. However, as the action unfolds, there will also be moments of celebration as Burgess and Ruzek finalize their wedding plans.
It’s possible that one of the crossover episodes will feature a major case that threatens to derail the wedding, forcing Burgess and Ruzek to reconsider their priorities. But knowing these two, nothing will stop them from finally saying “I do”—especially with so many loved ones by their side.
What This Means for the Future of Chicago P.D.
With the wedding being such a significant moment, it raises big questions about what’s next for Burgess and Ruzek. Will this mark the beginning of a new, stable chapter for them? Or will their union be tested by the dangers of their jobs?
Either way, the 2025 One Chicago crossover is shaping up to be an event fans won’t want to miss—one that will deliver both edge-of-your-seat drama and heartwarming moments for Burgess, Ruzek, and the entire Chicago P.D. team.
