So, it has been a while since the One Chicago universe has introduced a new cross-show romance. The last one involved Brett and Antonio,

and they split seven years ago. It’s high time for One Chicago to resurrect this tradition, and thankfully, it seems like NBC and the producers are doing so via Novak and Frost in Chicago Med.

 

 

Additionally, Gabby formed a fleeting connection with Halstead in Chicago Fire. But he soon joined the Intelligence Unit in the Chicago PD series premiere, ending their relationship. Gabby’s brother, Antonio, who starred in Chicago PD, also dated Brett from Chicago Fire for a short while in the procedural drama’s sixth season before they broke up.

Novak is expected to be “crossing over a bunch with Chicago Med for intriguing reasons.” Newman didn’t explicitly state why Novak would be appearing in multiple episodes of the medical drama, but one could be able to guess the reasoning. First of all, Novak is one of Firehouse 51’s paramedics. She goes to Gaffney all the time while on the job.

 

 

However, a romance with Dr. John Frost is the more likely explanation behind Novak’s growing presence in Chicago Med in season 11. Sparks flew between Novak and Frost during the 2025 One Chicago crossover. So, with Jack Damon leaving Chicago Fire, the door is now open for Novak to explore new relationships, and she already has an intriguing connection with Frost.

A few weeks ahead of the One Chicago premieres in fall 2025, TVLine learned from Chicago Fire showrunner Andrea Newman that a crossover is already in the works. In fact, more than one has been planned. According to Newman, Chicago Fire season 14 and Chicago Med season 11 will deliver “a bunch of” mini-crossovers, with Lizzie Novak at the center of it all.

These events are what make One Chicago special — they are a part of its DNA. Without crossovers, the franchise wouldn’t be nearly as successful as a whole as seeing how all three shows are connected is beyond thrilling. A One Chicago crossover is essentially network TV’s version of Avengers: Endgame, and thankfully, this tradition will continue in the fall of 2025.
