Ranking Every Couple On Chicago Fire

The series that kicked off the "One Chicago" franchise has seen its fair share of romances. "Chicago Fire" has well over a dozen memorable characters — some of which have come and gone — and all of them have been involved in some sort of romantic storyline throughout the course of the series. While a good portion of these were something worth rooting for, others were a total disaster to watch unfold. Some "Chicago Fire" couples continue to stand the test of time, while several had only a few episodes worth of story before they fizzled out.

"Chicago Fire" definitely gives "Chicago P.D." and "Chicago Med" a run for their money in the romance department — which could be thanks to Mr. Kelly Severide (Taylor Kinney) — as the series has had more relationships than the others during its tenure. We decided to rank all of these couples from worst to best, and it wasn't an easy feat. There are some flings missing from the list, as it primarily focuses on stronger relationships, and we'd honestly be here forever if we included every hookup from the show. Take a scroll and see if your favorite "Chicago Fire" couple landed toward the top.

Renee Royce (Sarah Shahi) is the perfect trickster. She works her way into Kelly Severide's life in Season 1, and the two seem to fall in love with one another genuinely. Renee ends up moving to Spain for a job promotion, and despite getting an invitation to come along, Kelly stays in Chicago. He is pretty devastated from the breakup, but Renee comes flying back into his life in the Season 1 finale and tells him that she's pregnant with his baby.

In the Season 2 premiere, Leslie Shay convinced Kelley that the math doesn't add up regarding Renee's pregnancy. When she's called out on it, Renee finally admits the baby isn't Kelly's, and the pair officially break up. It's not the last we see of her conniving ways, as she tries to work her way back into Kelly's life in Season 6 when she asks for his help in a court case. Despite being warned by Stella Kid (Miranda Rae Mayo), Renee tries to woo him to back off. At this point in the game, Kelly's a changed man and only has eyes for Stella. Despite Renee and Kelly starting off on great terms, she becomes a garbage person, which makes their relationship one of the worst in the series.

Violet Mikami (Hanako Greensmith) joined "Chicago Fire" in Season 8, Episode 10 ("Hold Our Ground"), and we learned she has a history with Blake Gallo. The two attended the fire academy together, and it's clear they have some sexual tension from the get-go. Once they alleviate that tension, they start dating but soon declare themselves non-exclusive — a stance that always works out.

In a twist that surprised no one, Gallo and Violet's jealousy causes them to break up. They are one of the most easily forgotten couples in "One Chicago" history, which is no easy feat given that they are also one of the most recent. This duo serves much better as friends than lovers, and we choose to keep their coupling a distant memory. It seems as if a romance was the easiest way to introduce Violet into the show, but she appears to be on to bigger and better things these days (ahem, Hawkins).

When we first met Matthew Casey (Jesse Spencer), he was hiding the fact that his engagement to his fiancée, Hallie Thomas (Teri Reeves), was over. No one at Firehouse 51 knew, but eventually, Gabby Dawson (Monica Raymund) and company caught on. Casey and Hallie had an on-again, off-again relationship for about eight years, but the last that they were on again, they were quite the couple. Hailee is murdered in Season 1 when she accidentally discovers a drug trafficking operation at a clinic she volunteers at, which absolutely guts Casey.

Hallie and Casey were a decent enough couple, but it was always obvious that this relationship was just a roadblock in what would eventually be known as Dawsey. It wasn't a relationship you could take seriously, because Casey and Dawson were clearly going to end up together — especially with how the show constantly showed off how jealous the latter could get at times.

Gabby Dawson always had a crush on Matt Casey. He was unattainable due to his relationship with Hallie Thomas, and then later, his drama with his mother made his life too complicated for a girlfriend. Gabby was never able to go after the man she wanted, so she set her sights elsewhere. Romance blossomed out of a friendship with Peter Mills (Charlie Barnett), but something never felt quite right about it.

Peter was never going to be Gabby's number one, as Casey always held that spot. Gabby led Peter on for far too long, as she could never shake her feelings for the lieutenant. Gabby also finds out that Chief Boden (Eamonn Walker) had an affair with Mills' mother and holds the secret for a while. When Mills finds out, they break up, which is probably the best thing that ever happened to him. He was also onto Gabby about having feelings for Casey, and this relationship just seemed like the second roadblock to Dawsey becoming a thing. Gabby and Mills actually become really great friends, and we wish they never dipped their toes into the romance pool.

Severide and Erin Lindsay (Sophia Bush) are one of the many "One Chicago" crossover relationships. While it might be better to classify their relationship as a fling, there were some serious feelings between the two, and they were a duo that fans definitely had opinions on at the time. The "Chicago P.D." star made her way into the "Fire" family in Season 2 when she investigated the kidnapping of Katie. She and Severide are attracted to one another immediately and share one of the steamiest kisses in "Chicago Fire" history.

However, the death of Shay brings their fling to an end as Kelly slips into a depression and stands up Lindsay on several occasions. She promises to always be there for him but says she is not a woman who will sit around and wait for him. Luckily, she moves on rather quickly to Jay Halstead (Jesse Lee Soffer), and they serve as one of the best couples ever on "Chicago P.D."

The first love interest we get to see for Brian "Otis" Zvonecek is Katie Nolan (Brittany Curran), the half-sister of Kelly Severide and daughter of Benny Severide (Treat Williams). The two tried to keep their affection from one another away from Kelly, who was overly protective of a half-sister he never knew existed. Otis and Katie only get to date for a few episodes, but we get to see how much he cares for her after Vince Keeler (Jacob Weary) kidnaps her as revenge against Kelly.

Otis visits Katie in the hospital after she's rescued, but the two have to end their fling because she is too traumatized to stay in Chicago. She ends up moving to New York to accept a position in a restaurant (one she initially debated taking because of Otis), but she goes on to live a happy life in the Big Apple. She returns for Benny's funeral in Season 7 and runs into Otis, and it's obvious there are still sparks between the two, but he had moved on to someone else at this point. If Katie was never kidnapped, she very well might have lived a happy life with Otis — until his untimely death in Season 8, that is.

The sparks are instant between Sylvie Brett and Kyle Sheffield (Teddy Sears) in Season 7. The new Chaplain for the CFD takes a liking to Brett instantly, but he ends up breaking her heart when he dumps her because of his job. Matt Casey makes an excellent point to the Chaplain — that it's hard for people of the CFD to confide in him if he's dating someone within the department. However, it's not the end of their romance.

Kyle proposes to Sylvie in the Season 7 finale after he's offered a position in Indiana, which will take him out of the CFD. Knowing how incredible she is, he wants her to come with him, and Sylvie somewhat hesitantly accepts the  proposal. Around this time, something starts to brew between Casey and Brett, but she still accepts and leaves Chicago. In the Season 8 premiere, she tells Kyle she can't be with him and misses 51 too much. She moves back to Chicago and back into Casey's life.

Brett and Kyle made a really great couple, and there was nothing wrong with their chemistry or relationship. They were just two wonderful people who wanted different things.

Antonio Dawson (Jon Seda) was a staple on "Chicago Fire" before "Chicago P.D." was even a thing. He's introduced as Gabby Dawson's brother in Season 1 and is constantly helping out the firefighters of 51 when they need police assistance. In Season 5, he and Brett begin their on-again, off-again relationship, which is quite steamy. Antonio tries to thwart Brett's advances at first but eventually falls for her. They start dating but end things, only to get back together again in Season 6.

Antonio and Brett are a super messy couple, despite having great chemistry. It was another one of those situations where the timing wasn't right — thanks largely in part to Antonio's ex-wife. They further prove that crossover relationships in the "One Chicago" universe are doomed from the start, no matter how fun or perfect they might appear. We wish they had more time to grow with one another, because Antonio and Brett sure were a lot of fun to watch.

Cruz had a complicated romantic run on "Chicago Fire" before eventually finding Chloe Allen (Kristen Gutoskie). He saved his soon-to-be-wife in her debut episode, Season 7's "Going to War," and nothing was the same for him after. The two hit it off immediately, and Cruz's love was Chloe was more evident than ever when she got in a car wreck that same season. He met her parents at the hospital, and Chloe's mother told Cruz that he was one of the best things that happened to her and that she needed him badly.

After Otis's death, Chloe gets nervous about dating a firefighter but ends up staying with Cruz, and they get married late into Season 8. They welcome a baby boy in Season 9, named Brian after Cruz's late friend. Only one of the few married couples on "Chicago Fire," Chloe and Cruz solidify themselves as one of the best couples on the series and will hopefully stick together for the show's tenure.

If someone told a "Chicago Fire" fan in Season 5 that Sylvie Brett and Matt Casey were going to be a thing one day, they probably would have rolled your eyes. After the demise of Dawsey, it only took a handful of episodes before there were side glances between Brett and Casey. However, neither one of them realizes it until Brett's spin instructor points out that they are meant for each other. With the seed planted, Brettsey began to bloom. Is it weird that Casey was married to Brett's best friend? Or that Brett dated Casey's former brother-in-law? Sure. But this is a Dick Wolf series, and the rules that might apply in our world don't on his small screen.

Brett and Casey have a really wonderful relationship from mid-Season 9 through mid-Season 10, but the "Chicago Fire" fandom was shocked when Jesse Spencer left the series. The two are still going strong as a long-distance couple, and we'd be surprised to hear they'd call it quits. Here's hoping they reunite at Stellaride's wedding, and maybe Casey will come back to Chicago, or Brett will head off to Oregon.

Stellaride. One of the best "Chicago Fire" pairings and one of the best couple nicknames ever created. When Stella Kidd joined the hit series in Season 4, it was obvious there was a connection between her and Kelly Severide. The chemistry between the pair was undeniable, and there was no fighting their relationship, no matter how many flings got in their way.

Despite having some serious bumps in their road, Stellaride is one of the most beloved couples on "Chicago Fire," and their engagement was the cherry on top. They might have had a very rocky Season 10, but their bond is something that's simply unbreakable. We saw Severide in his playboy days, and Stella is clearly the only person that can make him a one-woman man. Stellaride has a legion of fans behind them, hoping to see the best wedding the One Chicago universe can offer.
