The One Chicago universe almost made one of its boldest moves yet: transferring a major Chicago Fire character into Chicago P.D.’s Intelligence Unit. Scripts were drafted, schedules rearranged, and producers were ready to roll — but the entire plan collapsed when one longtime P.D. actor reportedly refused, saying the new addition would “mess with the chemistry.”
Sources say the transfer was meant to energize P.D. Season 13 with a firefighter stepping into Voight’s morally gray world. The crossover would have been emotional, dramatic, and deeply personal — one of the biggest franchise shake-ups in years.
But when the P.D. actor delivered a firm “absolutely not,” the storyline died instantly. Writers scrapped pages, a planned multi-episode arc vanished, and NBC quietly canceled what was set to be a heavily promoted crossover week.
Insiders say the Chicago Fire actor chosen for the jump was well-established and fan-loved — leading many to speculate it could have been Mouch, Ritter, or another familiar face. The actor was reportedly excited about the move and “deeply disappointed” when it fell apart.
Not everyone on P.D. agreed with the shutdown. Some cast members felt Intelligence desperately needed “new blood,” but the veto carried enough weight to stop the entire plan.
Now, both shows are reworking storylines, and NBC still hopes to engineer a major transfer someday — just not this one, and not right now.
For fans, it’s the biggest “what could have been” in recent One Chicago history: a crossover that almost rewrote the franchise, blocked by two words — no way.
