Since the very beginning, crossovers have been a key part of the DNA of NBC's One Chicago franchise. In looking to establish the universe that would become the One Chicago franchise, the creative teams worked hard to craft a world where the characters didn't just all exist in their own bubbles, but actually coexisted.

Characters from Chicago Fire, Chicago Med, Chicago PD, and yes, even the often forgotten Chicago Justice crossed over naturally into other shows in the franchise via quick cameos. This resulted in the franchise truly feeling like a shared universe in which the characters naturally crossed over as everyday first responders working out of the same city would in the real world.

It didn't hurt that the franchise also introduced several interconnected characters within the shared universe, establishing strong relationships between characters which spanned from romantic relationships to sibling dynamics. This made those connections even more natural as it wasn't surprising at all when you'd see a character such as Jay Halstead pop up on Chicago Med for a storyline involving his brother, Dr. Will Halstead. Or when you'd see a character such as Trudy Platt drop by Firehouse 51 to visit her husband Randall "Mouch" McHolland.

Beyond these smaller crossovers…..
