Chicago Fire will be first, then the drama that starts there will overlap with what happens on both Chicago Med and Chicago PD.
“BREAKING NEWS: our second episode of the season is going to be a three way crossover with Chicago Fire leading the way,” Haas wrote, complete with an Eleven reaction GIF.
Producer Derek Haas, the creator of Chicago Fire, took to Twitter to announce that all three of NBC’s Chicago shows will crossover again this season.
In addition to Haas, much of the creative team Chicago Fire also works on Chicago P.D. and Chicago Med, which has created a ready-made shared Chicago-verse for the small screen.
