The initial idea of both The Rookie and 9-1-1 being set in the same universe really happened after 9-1-1 moved from FOX to ABC. With both shows now on the same network, it made it much easier to bring a storyline that would affect them both. 9-1-1 even cemented that idea after it crossed over with Doctor Odyssey, albeit that was a little easier as both are also Ryan Murphy shows as well as ABC shows. On top of both The Rookie and 9-1-1 airing on the same network, there is also the fact that both are set in Los Angeles, making a crossover event seem plausible. Nobody has to go to a different state to make the show work, such as when 9-1-1 crossed over with 9-1-1: Lone Star. It would make it easy for a character or two to show up, without the need for a major event to take place.
Okay, let’s be honest—when you’re binge-watching The Rookie and then switch to 9-1-1, have you ever felt like something just clicks? The tone, the tension, even the way emergencies unfold… it’s like they live next door in the TV world. Well, you’re not alone. There’s a buzzing theory out there that The Rookie and 9-1-1 actually exist in the same universe, and honestly? The evidence is stacking up. Let’s break it all down, piece by piece, and explore why this theory is more than just fan fiction.
TVLine looked into this and reported that some of The Rookie cast has even heard people calling for a crossover between the two, but in the, The Rookie showrunner Alexi Hawley has ruled out the idea. He decided that it would be too “hard” to do, as it would mean there would be an expectation to see the characters show up in each other’s universes after the crossover. Los Angeles is big, but it’s not so big that Nolan and Athena wouldn’t end up crossing paths now and again on calls.
Bridget Regan Plays The Villain In Both 9-1-1 Season 8 & The Rookie Season 7. Who Bridget Regan Plays In The Two Shows That being said, Regan coming into both shows at the same time as villainous characters certainly opens the door for a crossover event. In The Rookie season 7, Regan has returned after already appearing as one of The Rookie’s villains, Monica Stevens. She is a lawyer who represented Elijah Stone, who turned out to create problems for Wesley and led to him being disbarred, and she is also Wesley’s ex-fiancée. Now, Monica is back to create more issues for the LAPD. Due to this, she has sped up the incubation period for a deadly disease, and she has taken the only anti-viral for it, making it impossible to save Chimney from the fateful disease.
Meanwhile, in 9-1-1 season 8, Regan plays a researcher who isn’t afraid to break the rules to further her research and testing. Due to this, she has sped up the incubation period for a deadly disease, and she has taken the only anti-viral for it, making it impossible to save Chimney from the fateful disease. Regan’s Moira in 9-1-1 is out in the city at the moment, and we’ll need to wait for the second part of the contagion event to find out how she’ll be caught and if it will be in time to save Chimney.
So, are The Rookie and 9-1-1 in the same universe? While nothing’s officially confirmed, the pieces are there, waiting to be connected. If you’re like us and love looking for clues, keep your eyes peeled. That moment when Nolan bumps into Hen or Chimney could be closer than we think. In a TV world full of surprises, this crossover is just one well-timed emergency away.
