It has been more than five years since the lastOne Chicagocrossover event, meaning that the shows' casts have drastically changed andthe 2025 crossover has the opportunity to bring numerous new duos together.The NBC franchise consists of three series —Chicago Fire, Chicago PD,andChicago Med. Each procedural drama has released 10 or more seasons, and they have produced almost 700 episodes as a collective. So, it’s safe to say thattheOne Chicagouniversehas been a massive success for the network. Part of why it’s so popular is its ability to have crossovers.

TheOne ChicagoTV shows will all return on Wednesday, July 11, 2025, withChicago Medseason 10, episode 9 at 8 pm ET,Chicago Fireseason 13, episode 9 airing at 9 pm ET, andChicago PDseason 12, episode 9 at 10 pm ET.

Gianna Mackey, Joe Cruz, Kelly Severide, Stella Kidd, Violet Mikami, Sylvie Brett, and Matt Casey in Chicago Fire.

Chicago Fire, Chicago PD,andChicago Medhave joined forces on various occasions, whether for a big three-part event or a quick cameo. The shows have undoubtedly benefited from these crossovers over the years as they introduce fans of one series to another and continue to establish the fictional universe. However, the lastOne Chicagofranchise crossover was five years ago(“Infection” in 2019).The lack of these events is mostly due to the COVID-19 pandemic,which resulted in productions enacting strict protocols. The good news is that the frustrating streak will end withtheOne Chicagothree-way crossover in 2025.

8Voight & Pascal

Chicago PD & Chicago Fire

One of the most obvious pairings we’re dying to see isChief Dom Pascal fromChicago Fireand Sergeant Hank Voight fromChicago PD.Pascal and Voight have similar personalities (gruff, no-nonsense, willing to get their hands dirty, etc.)and will either get along very well or be mortal enemies. Each option would be welcome as both would result in an intriguing dynamic for the crossover.

All Of Chicago Fire’s Firehouse 51 Romance Ranked

Over the course of Chicago Fire’s 13 seasons, there have been many romances between coworkers at Firehouse 51, some more successful than others.

Pascal and Voight might be too alike for them to be friends, which is ironic but also a very real possibility. It’s always interesting (and sometimes frustrating) to see the bosses of differentOne ChicagoTV showsclash, and that may be the case for the 2025 crossover event. Pascal is the new guy, after all, andVoight might not take kindly to Dermot Mulroney’s character taking chargeduring whatever crisis the firefighters, police officers, and doctors face.

7Kylie & Kiana

Chicago Fire & Chicago PD

Seeing two of theOne Chicagoleaders interact would undoubtedly be exciting, but so would watching two of the newest franchise characters become a duo. Katelynn Shennett joined theChicago Firecast in season 8, while Toya Turner became aChicago PDseries regular in season 12. Shennett’s character,Kylie Estevez, has been a recurring player ever since, but she officially joined Firehouse 51afterChief Pascal fired Jack Damon inChicago Fireseason 13.Turner’s Kiana Cook is a police officerwho becameHailey Upton’s replacement inChicago PDseason 12.

Since they are technically newbies in their respective fields,Kylie and Kiana could bond over their similar freshman status.Both are young, determined, and forces to be reckoned with. Who wouldn’t want to see Kylie and Kiana interact during the 2025One Chicagothree-way crossover? The upcoming event’s story reportedly (perTVLine) revolves around an office building explosion, which easily opens the door for many new duos, including Kylie and Kiana.

6Novak & Frost

Chicago Fire & Chicago Med

Following Jack Damon’s exit from Firehouse 51 inChicago Fireseason 13, Lyla Novak has been without a love interest. Kelly Severide’s half-brother was never more than someone Novak flirted with, and she deserves some love in her life (especially after the traumatizing fall finale). Hopefully,Chicago Fireseason 13 isn’t setting up a romance between Novak and Chief Pascal, and the paramedic can meet someone her own age who isn’t married or her superior. The good news is thatChicago Medhas just the person for Novak — Dr. John Frost.

Only time will tell if Frost and Novak even cross paths during the crossover, but their jobs make an introduction easy.

The nextOne Chicagothree-part event presents the perfect opportunity to establish another cross-show romance.Many couples have consisted of characters from other shows (likeChicago Fire’s MouchandChicago PD’s Trudy Platt), and it’s time for a new one. Darren Barnet has chemistry with every actor he works with. So, there’s no doubt that his character and Novak can stir up some chemistry between them. Only time will tell if Frost and Novak even cross paths during the crossover, but their jobs make an introduction easy.

5Torres & Ripley

Chicago PD & Chicago Med

A Dante Torres and Dr. Mitch Ripley duo might be unlikely,but that doesn’t mean it wouldn’t make sense. Both characters have troubling pasts they could bond over and are relatively new to their respective jobs. Although it may be unexpected,Chicago PD’s TorresandChicago Med’s Ripley could make for a fascinating dynamic. Some of TV’s most iconic friendships were developed between the most unexpected pairs, after all.

The 2025One Chicagocrossover event allows the writers and producers to form any tandem they want. So, this might bethe only time for them to establish a friendship between Torres and Ripley.Following the fall finales ofChicago PDandChicago Med, that kind of relationship might just be what both characters need.

4Carver & Ruzek

Sam Carver has been going through a lot inChicago Fireseason 13, and he could use some advice from someone who has been in his spot.Chicago PD’s Adam Ruzek knows what it’s like to fall in love with a coworker. He also understands how that relationship can fizzle out fast. So, perhapsCarver can learn a thing or two from Ruzek during the upcomingOnce Chicagothree-part crossover.

Katelynn Shennett

Kylie Estevez

Sure, Ruzek and Burgess are stronger than ever inChicago PDseason 12, but it took them a lot of time to get there. Hopefully, Carver won’t have the same experience with Violet Mikami with some guidance from Ruzek. The police officer can set Carver straight and put him on the right path concerning his slow-burn romance with Violet.Carver can learn from Ruzek’s mistakes,and fans won’t have to wait as long for Carver and Violet to becomeendgame as it did with Ruzek and Burgess inChicago PD.

3Violet & Lenox

Speaking of Violet, a meet-up between theChicago Fireseason 13 characterand one ofChicago Med’s newest doctors could be quite entertaining. Unlike most of the other hopefulOne Chicagoduos,Violet and Dr. Caitlin Lenox probably wouldn’t get along.Their tandem might be more similar to a rivalry than a friendship.

It would also just make sense for [Violet and Lenox] to cross paths as Lenox is the (now sole) head of the ED at Gaffney Chicago Medical Center, and Violet is a paramedic who often ends up in that very same ED.

BothOne Chicagocharacters are headstrong, passionate,and experts in their respective fields. However, Violet undoubtedly gets in touch with her emotions more frequently than Lenox ever does. For that reason alone, watching Violet and Lenox on the screen together would be rather interesting. It would also just make sense for them to cross paths as Lenox is the (now sole) head of the ED at Gaffney Chicago Medical Center, and Violet is a paramedic who often ends up in that very same ED.

2Asher & Burgess

Chicago Med & Chicago PD

Whereas it’s easy forChicago Firecharacters(especially the paramedics) to interact with those onChicago Med,it’s a bit harder forChicago PDcharacters to form strong bonds with the doctors and nurses at Gaffney(unless they’re brothers). But a three-part crossover event certainly helps. Perhaps it will allow for Dr. Hannah Asher and Detective Kim Burgess to cross paths in theOne Chicagouniverse.

Goodwin’s Deadly Stalker May Be Chicago Med Season 10’s Biggest Returning Character Thus Far

The exciting news about Chicago Med season 10’s biggest returning character could be a set-up for a shocking reveal about Goodwin’s stalker.

Although it feels like Asher has been working at Gaffney for a long time,Jessy Schram first appeared in aChicago Medseason 5 episode in 2020,before the lastOne Chicagocrossover. So, Asher hasn’t been a part of one before, and it will be intriguing to see her link up with characters from other shows, like Burgess.It’s easy to imagine Asher and Burgess becoming friendsand meeting up for the occasional beer at Molly’s after saving the city in the 2025 crossover.

1Pascal & Goodwin

Similar to the possible pairing of Chief Pascal and Voight, a tandem includingChief Pascal and Sharon Goodwin in theOne Chicagocrossover would also be exciting.Of course,Goodwin will have to survive her deadly stalker inChicago Medseason 10first. But there’s no doubt that she will make it out alive (despite the fall finale’s heart-racing cliffhanger).

Perhaps Chief Pascal, Goodwin, and Voight will share a scene or two during the 2025One Chicagocrossover, which would be the best-case scenario for all involved.

Chief Pascal and Goodwin could easily butt headsin the upcomingOne Chicagothree-part event. They might not have much in common as opposed to Chief Pascal and Voight, making it easier for them to disagree. Perhaps Chief Pascal, Goodwin, and Voight will share a scene or two during the 2025One Chicagocrossover, which would be the best-case scenario for all involved.
