Fans have long speculated that the fiery chemistry between two Chicago Fire characters wasn’t just acting. And now, years later, whispers from the set suggest they might have been right.
During the early seasons, the connection between Jesse Spencer (Captain Matthew Casey) and Monica Raymund (Gabriela Dawson) felt too authentic to be fake. While they always insisted it was professional, crewmembers recall late-night rehearsals, private talks between takes, and an energy that couldn’t be turned off when the cameras stopped.
One insider revealed, “They were very close. You’d have to be blind not to see the way they looked at each other.” Though neither actor ever confirmed a relationship, their real-life friendship faded quickly after Raymund’s departure from the show.
The tension between them was reportedly so strong that a planned reunion episode in Season 9 had to be rewritten due to “off-screen discomfort.” What happened between them? Only they know. But the chemistry was real—and something changed.
