One Chicago Reunion: Spiridakos and Soffer Return for 3-Show Crossover
Jesse Lee Soffer and Tracy Spiridakos return to Chicago P.D. for a three‑part crossover with Chicago Fire and Chicago Med, airing March 4 on NBC. Spiridakos’ Hailey Upton comes back as an FBI Special Agent, joining her former PD allies after a Detroit case pulls her to Chicago, while Soffer’s Jay Halstead returns undercover to crosspaths with the same case. The night will air in the Fire–Med–PD order, marking the duo’s first return to their roles since leaving the series.
