Portrayed by Monica Raymund

Gabriela "Gabby" Dawson (Seasons 1–6, Guest Season 7–8) is introduced as the Paramedic EMS in Charge of Ambulance 61, at Firehouse 51. Dawson gets in trouble for not strictly following procedure in order to save lives, which leads to her being written up several times and butting heads with Paramedic EMS Chief Hatcher. She was partnered with Leslie Shay for much of the first two seasons, and they shared a close friendship, but their friendship was strained after a call went bad. Both were well-liked by the all-male crew at 51, who are all very protective of them. She transfers to Truck 81 in season 3 after passing firefighter training.

Off-duty, she runs Molly's, a small bar jointly owned by her, Otis, and Herrmann. The bar is also popular with her brother's colleagues from the 21st District and the staff at Chicago Medical Center, whom the paramedics regularly come into contact with. She is usually in charge of the food and beverage aspects, while Otis and Herrmann deal with the business and marketing aspects.

The younger sister of Detective Antonio Dawson, a main character in spin-offs Chicago P.D. and Chicago Justice, Gabby is well known for being able to hold her own in a largely male-dominated occupation and an all-male firehouse; she and Shay were the only women at 51 until Brett was assigned to Ambulance 61 in season 3.

Dawson shared a close friendship with longtime colleague Matthew Casey even though they were each in relationships with different people. Later, she and the new candidate Peter Mills bond over their mutual love for cooking and begin a relationship in secret. When their relationship is brought to light, Casey seems to be jealous and pulls rank to keep them apart at work. She later discovers that Boden had had an affair with Mills's mother, and she keeps this knowledge from him. When he finds out that she had known about it and that she still has feelings for Casey, he ends their relationship, but they remain mutual friends. She had a brief relationship with Detective Jay Halstead at the beginning of season 2, but they mutually part ways. Following Casey's near-death accident in the season 2 episode "Not Like This", Dawson and Casey start a very serious romantic relationship, and Casey proposes to her.^[4] She later is a candidate at the Fire Academy. She fails her physical exam by several seconds, after injuring her ankle. In season 3, she has passed the Fire Academy. However, her relationship with Casey poses a problem due to fraternization rules, and she is initially assigned to Firehouse 105 in Austin under Casey's nemesis Lieutenant Welch. Welch was against her assignment to his truck company due to a past bad experience with a female firefighter. He fills the spot, and she is assigned as the candidate on Truck 81, under Herrmann's supervision. During her first few weeks on the job, Casey is extra protective of her, much to Herrmann's frustration, but she eventually settles in. In season 4, she suffers a miscarriage.^[5] Her return to duty coincides with Chief Riddle's quest to oust and make an example of Chief Boden so that he can make Fire Commissioner.^[6]

In season 5, Dawson decides to foster Louie, the child of one of the victims of a fire that Truck 81 attended, and the decision puts her at odds with Casey, who has doubts about having a child in their lives. Casey moves back in with her again and accepts Louie in their "family". After a close call involving both her and Casey, Dawson begins to consider the fact that if both of them remain at Truck 81, there is a possibility Louie could be orphaned. She decides to return to Ambulance 61 after the spot opens up when Borelli returns to the truck. She and Casey marry in the 100th episode as part of their plans to speed up Louie's adoption. However, Louie's biological father, who had up until then been listed as "unknown", shows up at both their apartment and the firehouse demanding to see his son.^[7] Louie eventually moves in with his biological father and paternal relatives.

Dawson and Casey reconnect after Dawson almost loses him in the fire that ended season 5. Dawson meets a girl named Bria in a fire. She finds out her father is addicted to meds and tries to help her, after not talking to Casey about it and instead talking to Severide. Casey finds out what they are up to and is upset. Dawson decides to let Casey help with Bria.

Dawson's old fling, Jake Cordova, comes to the firehouse since Otis is hurt, but things get crazy with Dawson. She doesn't tell Casey right away, which makes him mad when he finds out. When Otis is allowed back on the truck, everything goes back to normal, or that's what Dawson and Casey think.

Dawson gets a call from Bria asking to help her with some "girl problems", so Dawson does. She helps Bria get ready for prom. Casey decides that they can ride in the truck, so with Stella driving, Bria and her date ride to prom in the truck. While watching the truck pull away, Dawson tells Casey she wants to start trying again. After trying for a while, Dawson wants to get to the doctor to make sure everything is okay and to move the process along faster.

Finding out Dawson has an aneurysm that could burst with pregnancy, Casey and Dawson stop trying. Dawson tells Casey she wants to take the risk, but Casey says no, not wanting to lose her. He brings up adoption, which sets Dawson off since she doesn't want to go through the same thing they did with Louie.

In the last episode, Dawson is offered a job in Puerto Rico, which she turns down at the beginning of the episode. During the episode, Brett and Dawson fight on one of the calls, and then Dawson and Casey fight when they get home.

She departs Chicago after season 6 to help with relief work in Puerto Rico. In the Season 7 premiere, she briefly returns to Chicago and says goodbye to Matthew Casey.^[8] She returned briefly in the Season 8 episode "Best Friend Magic".

Portrayed by Kara Killmer

Paramedic Sylvie Brett (season 3 – season 12) joins Ambulance 61 following Leslie Shay's death. Initially, 51 is not enthusiastic about her arrival; most of the crew had known and worked with Shay for a long time and are still getting over her death. Despite a frosty beginning working together, Dawson becomes Brett's first friend in Chicago, and the others warm up to her soon after. She works alongside Peter Mills when he replaces Dawson after she transfers to Truck 81 as a candidate. Mills is not cleared for duty after an inner ear injury, which damaged his balance following the explosion where Shay died, so he is assigned to work on Ambulance 61. The two become good friends and partners while working together; as a Christmas gift, he gives her a wiggling hula-girl that sits on the rig's dashboard to this day. Like the rest of 51, Sylvie is upset when Mills chooses to leave for North Carolina with his family near the end of Season 3 and during his goodbye party, she breaks down in tears and hugs him goodbye. In late season 3, Mills gets replaced by Jessica "Chili" Chilton as the Paramedic In Charge (PIC); in mid season 4, Brett becomes PIC after Chili is fired and goes to rehab. Brett has appeared on the spin-off Chicago P.D. as the first responder on scene, crossing paths with members of the Intelligence Unit, and on Chicago Med and Chicago Justice.

Brett is a small-Midwestern-town girl from Indiana, where she grew up in a farm with her parents and a little brother. She frequented the church and even sang in the choir. She reveals to Dawson that she was adopted and never knew her birth parents.^[7] In her first episode, she self-proclaims she is a "runaway bride" who goes "up I-65 to Chicago" to escape her ex-fiancée Harrison after their engagement fell apart. However, a few episodes later her husband to-be finds her working at 51 and comes to visit her. He apologizes in front of everyone for leaving her before their marriage, revealing that he's the one who had cold feet. Nonetheless, she gets back together with him briefly until she realizes he has a very overbearing nature. He psychologically tries to dominate her by telling her how she should feel and where she should work. She tells him she's happy in Chicago but he tells her she isn't. She breaks up with him again and he leaves. Initially she has difficulty adjusting to city life due to her naivete, as shown by the fact that she leaves cash out on the table with the windows open and rented an apartment in a neighborhood known for crime because the rent is cheap. She also has a hard time handling some of the tough calls early on, but learns to deal with it and adapts quickly. She shares a new apartment with Gabby Dawson when the latter's relationship with Matthew Casey cools. Afterwards, she moves in with Cruz and Otis.

When Severide returns from a long furlough after Shay's death and first sees Brett going out to Ambulance 61, he does a double take, noticing the resemblance between her and Shay. While he is going through his grief process over losing Shay, he tries to hang out with her while deeply intoxicated, yet when sober and on the job, he treats her more coolly, a behavior that visibly throws her. After the two get closer while working together to help a single mom and her kid, Severide invites her to go to Vegas with him. She says she would love to, but doesn't know if that's a great idea so he leaves without her. This apparent mutual pull they feel for each other then ceases after he marries Brittany. Sylvie joins the best-rated Zumba class she finds on Yelp in her neighborhood and finds that the instructor is none other than Cruz. They agree to keep it a secret as long as she can teach him how to cook since he's opening Molly's 2 and she has skills that she no longer gets to use, but she ends up telling Casey due to his misunderstanding of her relationship with Cruz. She asks him to keep it a secret, but he ends up telling Dawson, who then tells Hermann, who then tells Mouch, who then tells everyone else. Joe then asks Sylvie out and she rejects him. However, she accepts some time later and they start dating. After a few months, the two break up once they realize they're not in love and remain good friends. At this point, Otis seems to realize he has feelings for her and considers asking her out. Later in Season 4 he asks her to the CFD gala and after initially rejecting him she agrees and they go together. He keeps meaning to ask her out again, but other people or things get in the way and in the end they remain just friends.

Brett appears to have a romantic interest in Officer Sean Roman from Chicago P.D. as they share an encounter in the season 3 finale of Chicago Fire. She reveals her feelings for Jimmy Borelli, when she finds out that Jimmy is leaving, she confesses her feelings for him, which she later tries to cover up when she finds out he is staying in the CFD and working alongside her as her new partner.

During a call in Season 4, Brett gets attached to a baby she delivers to a gunshot victim mother who dies in the ambulance. She visits the baby in the hospital several times until Chief Boden finds out and tells her to let it go and so does Chili. However, she still goes back, where she meets Dr. Charles (Chicago Med). He tells her secretly to check the father's details while the duty nurse is out. She goes to see him and tells him about the son but he ignores her. However, when she comes back to see the baby yet again, the dad is there and thanks her. She and Dawson also help host a wedding at Firehouse 51, where she sings.

In season 5, both Chili and Jimmy leave as paramedics, leaving Dawson to take their spot and work alongside Brett once more. During a case, Gabby's older brother Antonio Dawson shows up, and Sylvie instantly develops a liking for him. After some consideration, she asks him out but he refuses, saying his breakup with his ex-wife is still on his mind and he doesn't want her mixed up with this. She says she doesn't mind and they start going out. In the end of "An Agent of the Machine", Sylvie tries harder to impress Antonio's son Diego, who likes to play chess and whom she doesn't connect with. Joe teaches her the basics and Antonio asks her later to take care of Diego when he's called in to work. Antonio's ex-wife, Laura, shows up at the firehouse and takes Diego away, telling Sylvie to mind her own business and stay away from her family. This upsets Sylvie and she tells Antonio she doesn't want to be in the middle of his fight with his ex-wife. He says he warned her about this before but she replies that she didn't expect to be directly confronted by Laura. He lashes out and she breaks up with him. Antonio later shows up at Sylvie's door and apologizes, and even though she understands she tells him he's not ready and it's best if they stay apart. She later tries to get her mind off Antonio by doing extra exercise at the firehouse, trying to find online makeup classes and changing her look and even learning German. Dawson feels bad and tries setting her up with people Casey knows, but Casey doesn't want to get involved in her love life. In "A Man's Legacy", while in the hospital, she sees Antonio with his sister after visiting his father and talks with him. In "Foul is Fair", it was revealed that Brett breaks up with Antonio again, as they insist they should keep things casual but she fears if they keep seeing each other one of them will get hurt eventually. At the end of "Hiding Not Seeking", she has a one-night stand with Antonio in his car, then the two start seeing each other again. In "Looking for a Lifeline", Brett confides in Dawson, who suggests that Brett might be pregnant. She takes a pregnancy test, but is disappointed when it comes up negative, making her realize in "The Chance to Forgive" that she wants to spend the rest of her life with Antonio. She wants to talk to him about them making a real shot at a relationship, but before she can do so, finds out that he has been set up on a blind date. After the discovery, she clears her locker of anything to do with Antonio, declaring to Dawson that she is a new person.

In "It Wasn't Enough", her High School friend Hope Jacquinot comes for a visit and stirs up trouble, first by seeking out Severide's attention, despite Brett's warning that it is a bad idea to get involved with him as he is recovering from the death of his girlfriend. Then Hopes gets an office position working at the bullpen and Connie warns Brett that there are rumors that Hope had stolen money from her last employer. Hope says it was a misunderstanding following a bad break-up. Then she purposefully misplaces Stella Kidd's payment only so she can appear to come out as the hero in the situation, gaining Stella's favor. Hope forges a signature to get Kidd transferred to CFD's Public Relations Department to get her out of Firehouse 51 and away from Severide. Casey and Chief Boden find out, and she gets fired. Afterwards, Sylvie tells her to go back to Fowlerton and that she doesn't want anything to do with her anymore. Brett is very apologetic with her colleagues at 51 for bringing Hope into their lives and all the mess that followed, but people don't hold her responsible nor any grudges over what happened.

During the season 6 episode "Slamigan", Brett assists Cruz in creating a new firefighting tool since she grew up on a farm and has experience welding. This brings them closer, and it appears Cruz develops feelings for her once more. He spends the rest of season 6 battling his own feelings for Brett, which gets her aggravated at his overprotectiveness in a few instances. In the season 6 finale, he considers confessing his feelings for her, but once she declares how much she cherishes his friendship he decides to keep this to himself and move on from her.

In "The Grand Gesture", Brett is distraught over a stabbing victim who dies in front of her after being stabbed by a mentally unstable man. She is seen crying in her car after the call. She eventually explodes when Dawson also becomes angry and yells at her when she grabs scissors instead of gauze during a call. She is upset at Dawson for being treated this way, and they have a fight right before Dawson leaves to work at relief efforts in Puerto Rico.

In "A Closer Eye", Brett turns away every paramedic she is partnered with, believing Dawson will come back. She is then partnered with Emily Foster by Chief Boden, who tells her to make it work. At first, the chemistry between the two is a little rocky. In "Going to War", she confronts Casey about letting Dawson leave. He replies that there was nothing anyone else could have done. He also gives her a goodbye gift from her recent ex-partner: a photo of the pair, on the back of which is written: “Love you, partner, and always will." In that same episode, she shows Foster an intubating technique on a severely burned victim, which impresses the new paramedic. Brett says her old partner was a master at it and taught her well; it's the very same technique that Dawson taught her during the first episode of Season 3. She also learns that Foster was a surgical resident at Lakeshore Hospital and got kicked out of the program for cheating on her medical boards evaluation, as she was going through a rough patch in her personal life during her mother's sudden illness and death. After a rocky start, they form a good partnership at work and become good friends too, with Brett even defending Foster and berating a doctor at Lakeshore that "ghosted" her on a date.

In season 7, she dates Kyle Sheffield, a chaplain with the CFD and friend of Foster. They break up in "Fault in Him", with Kyle saying their relationship has led to firefighters not being willing to confide in him after Brett asks him to talk to Casey about a bad call he experienced. She has a hard time moving on and sympathizes with Casey on the subject of tough breakups. She then attempts to help him out by setting him up with her spin class instructor, Olivia, in "Try Like Hell". After a game night with their friends, Olivia says Matt is great, but that Brett should be the one dating him as she and Matt are "meant for each other". Later, Brett confides this to Foster and Kidd, who seem to agree with Olivia's assessment, leaving Sylvie confused about her feelings for Casey. In "I'm Not Leaving You", Kyle comes to 51 and proposes to Sylvie in front of everyone after he tells her he's moving to Indiana. Brett accepts his proposal and tries to make it work with him, but misses her life in Chicago and isn't happy in her new quiet life with Kyle, so they break up.

Brett returns to 51 in the third episode of season 8 after leaving Fowlerton and resumes working on Ambulance 61 with Foster. Her feelings for Casey still seem confusing, and she gets overly defensive when he assumes she is dating a guy who meets her for drinks at Molly's. She also meets her birth mother who wants to make a connection with her before giving birth to her second child. Sylvie spends time with her mother Julie until the latter dies giving birth. The baby survives and Sylvie becomes a half-sister to a baby girl name Amelia. Although her stepfather initially does not want to take care of her, Sylvie is able to persuade him to keep his daughter to honor his wife.

In Season 9, Sylvie is assigned a new partner Gianna Mackey and they become fast friends. Sylvie's status with Casey also evolves, with the two sharing a kiss. However, Sylvie fears his former relationship with Dawson will be a problem and calls it off before things go further. Her relationship with Casey becomes awkward for a period of time, but they continue to support each other. When Casey goes through a health scare, Sylvie is there to support him, which results in her breaking up with her boyfriend at the time, Greg Grainger. After Casey confesses his love to Sylvie, she too admits to him that she loves him, and they finally consummate their relationship in the season 9 finale.

In season 10 Casey moves to Oregon to look after Andrew Darden's kids, he maintained a long-distance relationship with Sylvie until the start of season 11, they broke up due to the distance and Sylvie felt they were growing apart. In season 11 Sylvie adopts a baby girl named Julia. In the season 11 finale "Red Waterfall" Casey returns to Chicago and proposes to Sylvie. They officially married in season 12 episode 6 "Port in the Storm", then Sylvie moves to Oregon permanently to live with Casey, their adopted daughter Julia and the Darden boys.

Portrayed by Eamonn Walker

Chief Wallace Boden (season 1 – 12) is the former chief in charge of Battalion 25 stationed at Firehouse 51. He is a scarred veteran of the fire department and served with Benny Severide and Henry Mills, the fathers of his subordinates, Kelly Severide and Peter Mills, respectively. Chief Boden has unwavering dedication to the firefighters under him and has earned their loyalty and respect. He will go to great lengths to protect the integrity of the firehouse and his men, even if it means having to antagonize them by disciplining them.^[9] His career is threatened after a feud with Gail McLeod when she tries to overthrow him and install his former colleague Benny Severide as the chief of Battalion 25. Boden refuses to give up his house and fights for it. Later she tries to "justify" the closing due to an incident at a call where the victim had to be cut out of a $40,000 trash compactor. McLeod is eventually removed and Firehouse 51 remains open. Despite his serious exterior, he is open to advice from his men, particularly regarding his personal life; for example, he asks Herrmann, who has five children, for tips on how to deal with his pregnant wife Donna and infant son and Mills for some insight while he was dating Donna. He also views his firefighters as his extended family, especially his two lieutenants, Matt Casey and Kelly Severide, who view him as a mentor and fatherly figure at 51. Stella Kidd looks up to chief Boden as a father figure since she lost her parents at such a young age.

Boden has an ex-wife, Shonda, and a stepson, James, who appear in season 1 and later in season 5. Shaunda owns a pancake and waffle restaurant on the south side of Chicago that Boden and his crew often visit. In season 2, while intervening on a fire in a building he meets one of the residents, Donna Robbins, an elementary school teacher. Being attracted to each other, they start dating until Boden breaks it off, being afraid of screwing up the relationship like he always does. After a while, he meets Donna again and learns that she's pregnant with his child. Soon after, he proposes to Donna, arguing that it would be better for the child since he will be able to support them financially. She turns him down, not convinced by his non-romantic point of view. Confused, Boden goes to Mills for some explanation. He understands then that he didn't speak about his feelings and, in full uniform, proposes to Donna again, successfully this time. He marries Donna in a small ceremony, the same day as her parents years ago. Herrmann is his best man and organizes the wedding ceremony in front of firehouse 51 with Mills as clergyman. Donna has some difficulties with her pregnancy, having a risk of fatal blood loss. At first she refuses to know the baby's gender unlike Boden who would like to know. She reveals to him later that they are expecting a boy. They have a son Terence who is born in Squad 3's truck en route to the hospital (Chicago Med).

Boden had an affair with Ingrid Mills, Peter Mills' mother, when she and her husband were separated. As soon as he realized they had still feelings for each other, he stepped back. Mills is very upset when he learns about the affair and remains angry at Boden for a long time. He has a bad relationship with Benny Severide due to their opposite views on the heroic death of Henry Mills. Benny Severide argued that Mills' death was due to his attempt to impress Boden who was having an affair with his wife. In season 5 Jimmy, now a high school student, comes to live with him and joins the crew at 51 to "observe" what life is like as a firefighter. However, Severide and Cruz both suspect that Jimmy is not telling the whole story.^[10] Jimmy finally confesses that his mother's new boyfriend had been abusing him physically whenever she is not around.^[11] In "Ignite on Contact", his wife Donna was almost killed when the high school she teaches is on fire and another teacher is seriously injured. It is later revealed to be arson and one of the students a suspect.

In "The One that Matters the Most", Boden contemplates moving up in rank after the CFD is considering promoting him. In "One for the Ages", after being encouraged by Casey and Severide to seek a promotion in "The Unrivaled Standard", he decides to run for Fire Commissioner of Chicago with the Mayor of Chicago endorsing him. In "The Grand Gesture", his run for the fire commissioner is stopped when allegations of bribery come to light. He then loses the campaign to Chief Carl Grissomr.

Boden's father Wallace Sr. (Richard Roundtree) lives in Orlando, Florida. In the episode "Ambush Predator", Boden finds out that his father has stage four cancer and has been given four months to live. Wallace Sr. peacefully passes away at his son and daughter-in-law's home at the end of the episode "Call It Paradise".

In Season 1, Boden gets close to Ernie, a teenager he sees several times on garbage fire interventions. Thinking the boy may be responsible for those fires, he invites him to the firehouse to investigate with Herrmann's help. It turns out that Ernie was under his uncle Ray's influence and he eventually dies in a fire set by Ray. His death devastates Boden. In Season 4, Boden invites Capt. Dallas Patterson to command Squad 3 after Kelly Severide is demoted from lieutenant to firefighter. Boden and Patterson are later seen playing poker with Sgt. Whitaker of Chicago PD. Boden faces legal troubles after a neighbor, Serena Holmes, accuses him of home invasion and assault. Holmes had moved into the apartment next to Boden and Donna as a temporary Airbnb tenant and requests Boden's help after locking herself out of the apartment, claiming that she had left the stove on. Boden forces entry into the apartment at her request, only to find the stove off and Holmes acting seductively. She offered him a glass of wine, which he declines before leaving. Later, a detective with Chicago P.D. confronts Boden at home and says that Holmes claims that Boden broke into her apartment and assaulted her with a wine bottle. The detective produces photographs that show an obviously battered Holmes. Knowing that he did not commit the crime, Boden enlists the help of Firehouse 51 to uncover the truth. Boden first suspects that Deputy District Chief Ray Riddle, who had been attempting to remove Boden from his post, may have put Holmes up to the job of sullying Boden's reputation. But with the help of Kelly Severide's ex-girlfriend, attorney Jamie Killian, it is revealed that arsonist Roger Maddox - who was set to go to trial for his crimes and who was being represented by Killian - hired Holmes to accuse Boden. It is also revealed that Maddox set out to discredit members of the department's Office of Fire Investigation (OFI), including captains Greg Duffy and Suzie Wilder, who were to testify against Maddox at the trial.

In Season 8, after the death of Otis, Boden is reluctant to bring Blake Gallo into his firehouse due to his daredevil antics but is convinced by Casey and Severide to give him a chance. He soon learns of Gallo's tragic history of losing his family in a fire and it is implied that Boden was the one who saved him as a child. Throughout Season 8, as a way to cope after Otis and seeing her potential as a leader, Boden takes Stella under his wing, giving her opportunities to prove herself. However, in doing so, Stella exhausts herself trying and causes an accident. Afterwards, Boden apologizes for turning her into his project, but she thanks him for the opportunity to so, strengthening their relationship.

In Season 9, after seeing Stella use her ingenuity to save Severide and a civilian, he offers her the chance to take the Lieutenant's exam. During this time, Deputy Fire Commissioner offers him a potential promotion to Deputy District Chief, which he gets in Season 10. Despite the challenges of his new role he remains confident that the family at firehouse 51 will stay together, no matter what.

At the end of Season 12, after realizing the department could fall into the wrong hands with a new Deputy Fire Commissioner soon to be appointed, he applies for the position and is promoted to the Deputy Fire Commissioner of the Chicago Fire Department. Wallace Boden is no longer listed as one of the main characters and is listed as a guest character now.

Christopher Herrmann (season 1 – present) is one of the senior firefighters of Truck 81. He is the third most-experienced firefighter at 51 (after Mouch and Boden), having served for nearly two decades. He passed the Lieutenant's promotion examination during season 2 episode "Virgin Skin" and was wait-listed until the Season 7 episode "This Isn't Charity" where he was finally promoted. He is generally considered Casey's de facto right-hand man on the job by the rest of the truck company,^[5] as shown by the fact that he was made Acting Lieutenant whenever Casey is off-duty or unavailable^[12][10] and also oversees Candidates assigned to Truck 81. Casey once described him as "the heart and soul" of Firehouse 51.^[13]

Outside his job, Herrmann was a self-described "day trader". There is a running gag in the show about how Herrmann would come up with ideas to solve his various problems and they would often backfire or go completely wrong. His sharp instincts on the job are in stark contrast to those when he is not at the firehouse, which include taking on several "get rich quick" schemes that have left him financially precarious. However, he seemed to have finally made a good investment by opening Molly's Bar, along with Dawson and Otis, after putting out a fire at the location and buying it out. Molly's was nearly another of his failed investments as paperwork mishaps, building code issues and competition from a large sports bar located across the street threatens closure. In season 1, one of his investments goes bad and he loses his home to foreclosure, forcing him and his family to move in with the in-laws for several months. In season 4, he attempts to run a rude and condescending couple out of town, after they sued Molly's for "breaching" the city's noise limits, by hosting karaoke night at Molly's and belting out the chorus of "Don't You (Forget About Me)" over the microphone.^[14] He also developed a near father-daughter relationship with Chili in season 3 as he immensely helps her design her dad's business idea, helping to fund and create it. The relationship greatly fades away by Season 4 as she breaks away from him and the rest of 51 after her sister's death and spirals into alcoholism. In season 5 he and Otis bring a discarded table tennis table back to the firehouse and end up smashing out a glass panel after the former challenges the rest of Truck 81 to a "show down".^[7]

Until the birth of Boden's son with his wife Donna, Herrmann was the only character on the show who was married with children. As such, he has a soft spot for young victims. In season 3, after learning that a young boy he had previously rescued died from a fire caused by his negligent alcoholic father, he had to be physically restrained by Casey from hitting the father in a fit of rage. Boden sought his advice many times about dealing with his pregnant wife and infant son. Herrmann is also the first to notice Dawson's strange behavior prior to her and Casey revealing her pregnancy to the crew.

Herrmann is portrayed as a hands-on father and devoted family man who considers his fellow firefighters and paramedics at 51 as part of his extended family; most of his colleagues have babysat his five children at some point and Herrmann has no qualms about discussing the children with his wife in front of them. In the episode "Path of Destruction" it is stated that he and his family live in the West Lawn area of Chicago. At the start of season 1, Herrmann and his wife Cindy have three sons and a daughter. In season 4 he stated that they have been married for twenty two years.^[15] Cindy had suffered a miscarriage before their first child Lee Henry.^[5] Their fifth child and youngest son was born in the season finale after a difficult birth. Severide and Shay are named as godparents. Herrmann is shown to be a doting father and husband who often speaks of his family. All five children were christened into the Catholic Church.^[4] Because Cindy is Catholic, she does not use birth control, which led to Herrmann's much derided decision to do a vasectomy as his 20th anniversary present to her so that she does not have to go through another pregnancy without compromising her religious beliefs. His co-workers all tried to dissuade him from going through with it but their "concern" backfires against them as Cindy reacted by laughing and hugging her husband.^[16]

When Rebecca Jones joins firehouse 51 as the new candidate, her cocky behavior doesn't sit well with any of the members. However, it's revealed that her father is constantly trying to stop her being a firefighter and shutting down all of her ambitions, which eventually drives her to suicide. Herrmann and Mills get into a heated argument following the cause of her suicide. Mills accuses Herrmann and the others of being uncaring and inconsiderate, which Herrmann fights against until revealing his guilt in that he saw her the night before and wondered whether him saying something to her would've changed the outcome. They get past this together. Herrmann looks into expanding Molly's into a franchise and pitches his idea to the group. Cruz and Mouch want in and after a good presentation, Herrmann happily accepts their proposal into expanding Molly's into a truck this time.

Herrmann and Dawson also have tension between them when she reveals she's going to be a firefighter at the end of season 1 from a bad experience with a female firefighter. When she finally passes her physical exam and becomes a candidate, Welch rejects her from 81 and quickly recruits a male candidate. This upsets her, so Boden overlooks her and Casey's relationship and lets her be the new candidate at 51. This doesn't sit well with Herrmann since Casey makes a habit of overlooking all of her mistakes, forcing him to do the same and not question her. She reveals afterwards that she has been deliberately making mistakes in hopes that someone will overlook their friendship and correct her.

When Chili joins 51, despite the at-the-time cold welcome, she tries to make friends but doesn't have a lot in common with the others. This is until she reveals she's in-midst of creating and designing a button on the side of beverages to cool them instantly in 5 seconds. Being a business investor, Herrmann immediately jumps in and tells her she can sell it at Molly's as soon as she's finished. He helps her a lot until Sylvie and Dawson tell him to calm and slow down since Chili is spending all of her money on it without leaving any to pay her bills. He says this to Chili who thanks him for his help, saying Herrmann reminds her of her own father who died but created the idea in the first place. They get emotional and he says he will be right with her.

Herrmann and Cindy gave Chili Molly's funds to help her idea, for which she is very thankful. They then celebrate their success when she finishes her design and test to see that it works, which it does. However, she's left deeply hurt and upset when they find that someone else has already created and launched it on TV. She cries but Herrmann tells her she will definitely come up with something else and hugs her.

In season 1, Otis, Herrmann, and Dawson buy a bar, which they call Molly's. They had been called to a fire there and the owner wanted to sell it and move to Miami. After agreeing to buy it, they discover that a local mobster named Arthur had conned his way into being offered a "minority" stake. Arthur repeatedly harasses the threesome, even nearly setting Dawson on fire before Detective Jay Halstead takes him down and arrests him. After much difficulty, Molly's has become an established bar and is popular with firefighters and cops (it is featured multiple times in spin-offs Chicago P.D. and Chicago Med). After Captain Patterson, then chief, tells Cruz to tell Freddy he can no longer come to 51, Herrmann happily offers him a job at Molly's to get him out of the gang life he wants to escape. He's friendly towards him. At the end of "Short and Fat", Herrmann is stabbed by Freddy, Cruz's friend, at Molly's bar after he tells a joke that Freddy takes as an offense. The doctors reveal that he's lost a lot of blood and it would be difficult for him to pull through. Things heat up between Rhodes (Chicago Med) and Severide after he accuses him of not treating Herrmann properly after Halstead (Med) says something about this to one of the others. However, he pulls through and is back to 51 soon. Although, the encounter leaves him with a shaky feeling and he is constantly on edge his first shift back - constantly worrying about Cindy and his kids even though he tries to hide this. He also tells Cruz not to mention Freddy to him again. He was later discovered by his co-workers in the crossover episode "The Beating Heart" and was rushed to Chicago Med. Freddy was later arrested by Chicago PD detectives, after he was rescued by firefighters from hanging on the fire escape. He makes a statement against Freddy in court. In "Not Everyone Makes It", he had to testify against Freddy about the events that led up to the stabbing. Freddy's father, also in prison, requests Herrmann to see him. Cruz tells him not to, and he says he won't but ends up going. He reveals that he used to beat Freddy and is the reason why he is the way he is. When Cruz convinces him that Freddy came from a hard life, he convinces the judge to be lenient with him. He eventually retracts his statement and they let him out with watch. Cruz helps him through it. Herrmann as well as other members of Truck 81 report their concerns about Jimmy Borelli to Boden. He is in attendance at Matthew Casey and Gabriela Dawson's wedding. Many other story lines include him dealing with Lee Henry, continuing to operate Molly's Bar, etc. In the Season 5 finale, he is seen performing CPR on Mouch, who appears to be having a heart attack. In the season 6 premiere, Hermann, as well as the rest of the firehouse fully return to normal lives. Luckily and surprisingly, he survives the fire that ended Season 5. In the Season 7 Episode "Thirty Percent Sleight Of Hand", he is promoted to Lieutenant of 51.

In season 8, he faces charges of conduct unbecoming when he moves a CPD squad car in order to help position Engine 51 for a hostage situation with a potential fire, and things get worse when he tries to make things square with the officer who filed the complaint. These charges are later dropped when Severide made a deal to join the Office of Fire Investigation in exchange for Herrmann's charges being dropped.

In Season 12, Chief Boden stated that after a little assistance by Squad Lt. Severide that he would like Engine Lt. Christopher Herrmann to take the Captain`s and Battalion Chief`s test and become the new chief of Firehouse 51.

Portrayed by Dora Madison

Jessica "Chili" Chilton (season 3–4) replaced Peter Mills as the new Paramedic in Charge (PIC) in season 3 after the latter leaves the CFD. The crew at 51 were initially lukewarm to her as they were still getting over Mills' departure, having warmed up and grown to like to their former Candidate.^[17]

She came from a dysfunctional family; her parents divorced not long after marrying and her mother became a heroin addict and eventually abandoned the family. Her sister Alissa lives in Kansas City and they lost contact.^[6] Prior to being cast on Chicago Fire, Madison actually appeared as Alissa on Chicago P.D. in the episode "Call It Macaroni". Alissa was one of Antonio Dawson's CIs and using the cash paid by the district for her tip, leaves Chicago to start a new life. When Chili joins Firehouse 51, despite the at-the-time cold welcome, she tries to make friends but doesn't have a lot in common with the others. This is until she reveals she's in-midst of creating and designing a button on the side of beverages to cool them instantly in 5 seconds. Being a business investor, Herrmann immediately jumps in and tells her she can sell it at Molly's as soon as she's finished. He helps her a lot until Sylvie and Dawson tell him to calm and slow down since Chili is spending all of her money on it without leaving any to pay her bills. He says this to Chili who thanks him for his help, saying Herrmann reminds her of her own father who died but created the idea in the first place. They get emotional and he says he will be right with her. Herrmann and Cindy gave Chili Molly's funds to help her idea, for which she is very thankful. They then celebrate their success when she finishes her design and test to see that it works, which it does. However, she's left deeply hurt and upset when they find that someone else has already created and launched it on TV. She cries but Herrmann tells her she will definitely come up with something else and hugs her. At the start of Season 4, Chief Boden is under watch and investigation up to the point he is arrested and demoted from Chief and replaced by Dallas Patterson. When Casey then sees Chili and Jimmy hanging out too closely with each other around the firehouse, he tells Jimmy to slow things since it isn't appropriate while they are under watch, especially with Patterson. Jimmy tells Chili this and she is okay. However, she shows inappropriate behavior again and when they're caught by Patterson, he gets worried but she laughs it off, which angers him and they break up.

Throughout the next few weeks, Chili behaves erratically and is constantly angry and raging at anyone who asks her anything or questions her. Sylvie assumes it's the breakup or the fact that Herrmann is in hospital but Jimmy tells her he doesn't think it's either of those. A brief moment of her crying in the hospital waiting room is shown but the reason still isn't revealed.

The next shift, the house is on lockdown from a tornado warning. Jimmy asks Chili if they can be friends, to which she agrees, but the next second, she lashes out and tells him he isn't worth it and that it's unbelievable he would break up with her just because Casey told him to. During a call later that day, Chili mistakenly injects a seizing victim with morphine instead of valium, which causes the girl to stop breathing altogether instead of stopping seizing. She zones out after this and Sylvie takes over, properly injecting the patient and therefore saving her life. Chili says it's no big deal. At the hospital, she lies to the attending when she says the reason the woman has morphine in her system is because she accidentally knocked over a bottle, causing it to break. Sylvie tries to talk to her about this later but she brushes her aside and is making plans to go out. Wary and finally tired of her behavior, Sylvie reports her actions and the syringe accident to Chief Boden. After Alissa's death, Chili starts drinking to cope and Borelli and Brett both witness her mood swings. While at Molly's, Dawson is talking to Antonio, who tells her that Chili's sister Alissa was found dead in her apartment a week ago. Boden asks her about this and she says she is fine, he gives her the second strike for the syringe incident though. She then apologizes to Dawson and Sylvie for acting rudely toward them, which they accept. However, they see her drinking the next night and are disappointed. She starts up again and during a call, Sylvie ignores a direct call from Chili, who then tells Boden she wants Sylvie gone. Sylvie also finds out that Chili was asked to leave from the last house because of her problem. Boden gets angry hearing this and asks her to work things out or she'll be gone from 51 too. They both work things out at a later case where she apologizes to Sylvie for nearly replacing her. She pushes them away by repeatedly brushing them off. Things go downhill again when Chili receives a package at her day off containing all of Alissa's belongings and she breaks down again. She then starts to make a habit of taking small breaks to drink and then come back and spray some breath spray and chew gum so the people don't notice. However, Severide notices her constant breaks and tries to talk to her but she ignores him and Sylvie tries to look past her issues. However, Severide eventually catches her out and tells her to talk to Boden or he will. She goes to see him and tells him she needs help and is willing to take time off to go to counselling but he fires her instead. He then tells her to ask for help and she says she just did and they did nothing. She goes to her locker and the whole of 51 follow, trying to talk to her. She says they aren't her family and leaves, including leaving her photos with them behind. Herrmann gets one of the photos and frames it and takes it to her apartment. He tells her through the door that she can always come to him and leaves the picture behind.

Chili calls someone and tells them she needs help. It's revealed it was Severide, who takes her to counselling and is glad she called. She tells him she'll call them and apologize. She thanks him and she goes to rehab. At Severide's urging she enters an alcohol rehabilitation program to get help.

In "Bad For The Soul", she was mentioned when Sylvie asks Jimmy if she's responded to their calls, which she hasn't.

Portrayed by Yuri Sardarov

Firefighter / Chauffeur Brian "Otis" Zvonecek (season 2– 8; recurring; season 1) was a firefighter on Truck 81 and was the most junior member at 51 until Peter Mills' arrival. Nicknamed after the eponymous elevator company as he is frequently assigned to elevator or ladder duty, Otis had just recently finished his candidacy^[20] before Mills joined the truck company. He is eager to move up the ranks within the firehouse but often feels overlooked and unappreciated by the rest of his truck company. The other more senior firefighters would pull rank, including Lieutenant Casey, and assign him to do undesirable menial jobs around the firehouse or pull pranks on him. This led him to consider transferring to another firehouse, but he ultimately decided to stay with Truck 81 after Severide pranks him into believing that the rest of the crew had placed a bet on how long he'd last at 51. In season 2 Otis begins a relationship with Katie, Kelly's half-sister. During "You Will Hurt Him", the house finally gets to meet Severide's half-sister Katie Nolan when she brings them lunch. Brian shows interest but Severide is very protective of his sister. She goes by the house again to bring them more food and tells Otis he should be home for dinner as Katie is coming over. They both bond over a game of Catan and end up kissing. Otis, then, asks Severide for his blessing as he wants to take Katie on a date. After messing up with him a little he eventually says yes. The two begin dating. Until she is kidnapped. Otis feels guilty he wasn't with her at the time it happened but Severide calms him and assures him it is not his fault. After she is found and taken to the hospital Katie makes the decision to move to Colorado. At the end of "Rhymes With Shout", Otis and Severide arrive to an empty and looted apartment. Shay gives Devon a key, and she steals all of their valuables, including Otis' collection piece (that later turns out to be completely worthless and fake). After this event Brian decides to leave the apartment and find his own space. Meanwhile, Cruz comes up to him and tells him that, since they are both "room-mateless", they should find a place together. It was revealed that Shay's runaway ex Devin absconded with their money and possessions. Later in the season, he and Cruz decide to room together. As the most tech-savvy of the crew, he becomes something of a cult figure amongst other firefighters due to his podcast, called "Good to be a goat" after Truck 81's mascot, about life as a firefighter. He often comes up with ideas and solutions for everything, much to his colleagues' amusement and derision. As of season 4, he was "promoted" to chauffeur as Cruz transferred to Squad 3. In "Joyriding", the day of the Union presidency vote, Mouch and his opponent Greg Sullivan have an all-important live debate on Otis' podcast. The debate is a disaster, Mouch opts to keep his integrity and to not use personal information on Sullivan that could ruin his run, thus losing the presidency. In "Just Drive the Truck", Cruz is suspended from driving for three months, pending investigation following the crash of Truck Co. 81 with Truck 66 from Welch's antagonistic Firehouse 105. Casey puts Otis as driver. In "The Nuclear Option", Otis' nephews come to visit the Firehouse and he is excited to take them on a ride while driving the Truck. Cruz's suspension is lifted, and he is now back in the driver's seat. However, on the last episode of the season Scott is kicked out of Squad 3 leaving a void. It's revealed that Cruz passed his squad certification and is now on squad. Otis is now the Truck driver. Dawson begins as a candidate, and Otis tries to prank her the same way the guys did to him when he first started, but since she was already at the house, she is aware of the pranks and manages to steer clear of them. Ever since Cruz broke up with Sylvie, Otis has shown interest in her. After the breakup, Sylvie comes up to him to return a book. After that conversation, Otis goes to Casey and says he might be in love with her. Casey tells him that it is crazy to even look at his best friend's ex the day after they broke up. During the entire season, Otis makes advances on Sylvie trying to go on a date with her. In "On The Warpath", he asks Sylvie if she has plans for the following night as Phantasm is showing at the Music Box. She has no idea what Phantasm is and the two are interrupted by Jimmy bringing Sylvie coffee. Brett gets herself into trouble, so Jimmy gives her a ride home. As they are both leaving, Otis tells Cruz that Phantasm was never going to happen. He stated his intentions, he even changed his looks but he finally realizes nothing would ever happen between him and Sylvie.

In season 1, Otis, Herrmann, and Dawson buy a bar, which they call Molly's. The bar is also seen on Chicago P.D. as it is popular with firefighters and cops. Otis is shown to be the more business-minded one and often had to remind Herrmann about paperwork for inspections and bills.

Otis is unabashedly proud of his Russian heritage and frequently speaks of his parents and his grandmother ("Baba"), although actor Yuri Sardarov is actually of Georgian and Armenian heritage. It is implied that Otis was either born in the United States or emigrated as a young child. He comes from a large family and every season has seen him introduce or speak of various relatives, with his grandmother even moving in and sleeping in his bunk bed. His father died of leukemia.^[18] Cruz was initially furious with Otis for only telling him the day "Baba", who spoke no English, shows up at their apartment but relents after Otis explains his reasons. In season 1 there was a running gag where he would tell his colleagues in any joint venture that he had "a cousin" who could come and help. For example, he gets his Russian cousin Zoya a job as a waitress at Molly's but incurs the wrath of business partners Herrmann and Dawson after they find out Zoya barely speaks any English.

In "I Will Be Walking", while changing in the locker room, Cruz asks him what happened to his back since he has a bruise the size of a bread basket. Otis gets suspicious about some bruises that appear on his back and hip. He asks Sylvie's opinion, who tells him to get it checked out by a doctor which he doesn't want to do fearing it might be something serious. He also asks Sylvie to keep it a secret from the house. In the episode "Kind of a Crazy Idea", eventually he decides to get it checked out by Dr. Halstead from Chicago Med. However, he still doesn't want to know the diagnosis and lies to Sylvie about having his blood results back and everything being ok. Later on, Sylvie finds out the truth and asks Cruz for help. Cruz enlists the help of Otis' grandmother, who after a visit to the Firehouse convinces him to get the tests done. Otis is diagnosed with immune thrombocytopenic purpura and went on medical leave. He returns to the firehouse, and he meets his temporary replacement and is convinced by Herrmann that Connie was trying to replace him permanently. Otis then takes Connie to the theater and she tells him that he always has a place at 51. Otis, along with other Members Of Chicago Fire Department Truck Company 81 are concerned about Borelli's Behavior following his brother's death. Other storylines included him still working at Molly's and still working as a member on truck.

In season 6, he goes into a relationship with Lily, whom he met when he visited a bar that was in the stages of closing, in what would become Molly's North.

In "The Chance to Forgive", while performing an evacuation on a house fire, he was shot in the neck and severely wounded. In a twist, the guns were inside the house and the ammunition was being fired due to the fire. He was eventually taken to Chicago Med, where Dr. Ethan Choi tells everyone that the bullet is lodged near his spinal cord and operating could cause serious problems. The owner of the guns won't be charged, since he owned them all legally and didn't intentionally hurt Otis. At the end, Otis got through his surgery in one piece. Choi sticks his head into the room and realizes that Otis can't feel anything in his toes.

Otis returns to active duty in "The Strongest Among Us", having fully recovered from his injuries, and butts heads with Kidd over who gets to drive Truck 81. He dies in a mattress fire after failing to get to safety in the Season 8 premiere, devastating the entire firehouse, especially Cruz.

Portrayed by Joe Minoso

Firefighter Joe Cruz (season 2 – present; recurring season 1) is the designated chauffeur for Truck 81. In season 3, he tries out for squad and has transferred to Squad 3 by the season 4 premiere.

Having grown up in the gangster-infested neighborhoods of Humboldt Park where he was regularly "lulled to sleep by gunfire",^[21] many of his peers were gangsters and he is constantly trying to keep his younger brother Leon out of the local gang. He is haunted by a decision that he made on the job related to his brother that later affects his own safety and the safety of his fellow firemen, forcing Casey to discipline him. Indeed, during a fire, he lets Flaco, the boss of his brother's gang, die, so Casey threatens to go to the police about Flaco if Cruz does not resign. Casey later reconsiders his decision. When Leon realizes what his older brother did, he vows not to let Joe down and enrolls at a local community college. Sergeant Voight seeks Cruz's permission to send Leon back into the gang, albeit undercover, after a little girl is killed in a drive-by shooting in his neighborhood so that the Chicago PD can shut down the gang once and for all. The takedown is successful but comes at a cost: Leon takes a bullet and eventually leaves Chicago for his own safety and starts a new life away from gang influence in Florida.^[22]

Cruz is generally well-liked by his coworkers and is often seen cracking jokes and exchanging banter with the rest of the crew. He and Otis often bicker with one another in the lounge during downtime over the most trivial matters. They later share an apartment together, thus referring to their arrangement as "Crotis" (a portmanteau of Cruz and Otis).

At the end of season 1 into a portion of season 2, Joe begins a relationship with Zoya, Otis's Russian immigrant cousin, and decides he wants to marry her to get her to stay, but she feels that is not right, so she leaves. In season 3, he begins dating the new paramedic, Sylvie Brett.

Seeing the success of the bar Molly's owned by Dawson, Herrmann, and Otis, Cruz decides along with Mouch to be part of the project. Cruz comes up with the idea of making "Molly's II" a truck. This project convinces Herrmann and is accepted. Finding a truck was difficult, but Newhouse finds one on the condition of being a 20% associate.

Joe was the driver of Truck 81 but received a suspension from Deputy District Chief Joel Tiberg when 81 got involved in a T-bone collision with Truck 66 from Firehouse 105 in Austin since they were both en route to the same structure fire. The collision resulted in Mouch sustaining a major eye laceration, two guys from Truck 66 having a broken arm for one and a broken leg for the other, and the driver, Jason Molina, being knocked unconscious. At first, he was accused of blowing a red light because he forgot the color of the traffic light and because he blew another red light 30 seconds before the accident. But when Molina woke up, he confessed that his Lieutenant, Tommy Welch, ordered him to beat Truck 81 so they could take command of operations at the scene. He was cleared of the accusation, and since Molina woke up, he was not charged with manslaughter. He still got 3 months suspension' from driving the truck and was temporarily replaced by Otis, who was next in line to drive 81. However, Chief Boden managed to reduce his suspension.

Cruz is a dance instructor and teaches Zumba when off-duty, a fact that he keeps a secret until Brett coincidentally turns up at his Zumba class because she lives nearby. He asks her to keep it a secret since he does not want to be ridiculed by his colleagues at 51. A running gag in the show is Cruz's inability to cook; he tries to fill in as the firehouse cook after Mills is promoted from Candidate status, but his cooking is often met with ridicule from the rest of the firehouse. He occasionally works as a bouncer at a bar.^[22] Since Cruz regularly talks to her about the class, Casey becomes suspicious and talks to Brett about romantic relationships inside the firehouse. To clear the misunderstanding, she reveals to him that Cruz is actually her instructor. Casey talks to Dawson, who tells Herrmann and so on until the whole firehouse knows about it. In "Chopper", the guys from Truck 81 and Squad 3 come to assist one of his classes. In "Spartacus", after Scott Rice is given the boot, Chief Boden announces that Cruz received his squad certification just before his shift started, and he is subsequently given Rice's spot just as a call comes in. At first, Otis is pissed Cruz did not tell him first due to the recent tensions between Truck and Squad but later congratulates him at Molly's.

In "Hiding Not Seeking", he grows increasingly concerned about Brett after she volunteers to go undercover to one of the bombing suspect's houses. After it was successful, he begins to take it out on her.

In "The Chance to Forgive", he becomes too personal when a call to a house fire goes awry and Otis is severely wounded. Cruz yells at the guy as he leaves the hospital in shame and vows revenge after Otis finally wakes up. Later in the hospital church, the father of the gun owner thanks Cruz for saving his life and says he didn't know his son had all those guns. When the call for another house fire at the same address as the first encounter comes in, the gun owner tries to kill himself due to his guilt over the events that play out. Cruz goes in and gets him. Moved by watching the kid nearly die, Cruz encourages him to stay alive.

At the start of Season 6's "Slamigan", Cruz creates a firefighting tool of the same name that combines a sledgehammer with a Halligan. Despite his annoyance of Mouch and Herrmann taking over the business side and credit for his hard work, the Slamigan proves to be an effective tool in the field, and he has used it on multiple occasions. Initially, his attempts to market the tool are hindered by his lingering feelings for Brett affecting his judgment, but in Season 8's "Welcome to Crazytown", he successfully proves the tool's worth at a firefighter expo against a flashier copy.

In "Going to War", Cruz saves a woman named Chloe Allen from a high-rise fire who in the next episode shows a romantic interest in him. Later, he asks her to accompany him to a firefighter picnic, and the two are officially dating by "The Solution to Everything". However, in "Always a Catch", Chloe is injured in a highway pileup and rushed to the hospital via helicopter. Cruz stays by her side with her parents, who remark he is good for her, and she recovers from her injuries. In Season 8's "Infection Part 1", Joe reveals his plans to propose to Chloe, but due to Otis's death and seeing the ramifications of being with a firefighter, Chloe breaks up with him. However, in the next episode, Brett manages to convince Chloe to give him another chance, and upon learning that Cruz was going to propose, she reconciles with him and happily accepts his engagement. Later, he asks Severide to be his best man.

In "My Lucky Day", Cruz reveals that Chloe is pregnant to Herrmann while they're trapped in an elevator, something that Cruz asks him to keep secret because he doesn't want to reveal it right away. He tells the rest of the firehouse in "Dead of Winter" when he gets good news from the doctor. In that same episode, Chloe reveals that they are having a boy. In "Two Hundred", Cruz and the rest of 51 are present for the birth of his son, Brian Leon, who is named after his late best friend, Otis.

Portrayed by Christian Stolte

Firefighter Randall "Mouch" McHolland (season 2 – present; recurring season 1) is one of the veteran firefighters of Truck 81. As the longest-serving member of Truck 81, he, along with fellow veteran Christopher Herrmann, is often seen as the ringleaders and respected by the rest of the crew as such. Mouch serves as union representative for the members of the station whenever they face disciplinary action or a lawsuit and is knowledgeable in the legalities and political side of the fire department. He has a part-time job as a security guard. Instead of "McHolland", he has "Mouch" written on the back of his turnout coat. With the help of Herrmann, he joins the race for fire union president but loses his chance to win due to his refusal to play dirty. When Firehouse 51 is about to be shut down, Mouch is the one who rallies the union's executive committee to stand up to Gail McLeod.

Infrequently referred to as "Randy", Mouch gained his peculiar nickname due to the fact that he can almost always be found on the couch watching television when not on a call ("half man, half couch"). He offends Boden's secretary Connie, who has the couch moved to the space outside Boden's office.^[23] He spends much of the episode distressing over the loss of "his" couch before succumbing to Herrmann's advice to apologize to Connie. She finally returns the couch to the lounge after Mouch apologizes twice.

Mouch was in a long-distance relationship with a Japanese woman named Mari. In season 1, Mouch was taking Japanese lessons. She is from Japan and comes to visit Mouch in A Hell of a Ride. She leaves in A Problem House. Mouch says he will try to visit her, but this never happens and they end up breaking up. Later, Shay sets him up with a "Golden Oldies" dating profile, and he acquires a blind date. His lack of social skills around women hinders him and his colleagues have had to "coach" him on the idiosyncrasies of taking women out on dates. He meets Chicago PD Sergeant Trudy Platt (Amy Morton), who also appears in Chicago P.D., by accident at Chief Boden's wedding reception and they have been dating ever since. As such, Mouch has appeared on Chicago P.D., usually to visit Platt. In season 4, he finally finds the courage to propose to Platt but it goes down the drain and they have to part ways after he is called to an emergency. Platt eventually proposes to spare him the embarrassment and they agree to get married. They marry in an intimate ceremony at Molly's, in the presence of Mouch's co-workers from 51 and Platt's co-workers from the 21st District.^[15] They went to the Wisconsin Dells for their honeymoon.^[24]

In a Chicago PD episode "All Cylinders Firing", after Platt was a victim of brutal assault, Mouch goes to Chicago Med to see her and while there, was questioned by Voight and Lindsay. He took offense when he was labeled a suspect by them. But he affirms his innocence and demanded to know the truth about what had happened. He was seen on another Chicago PD episode "Profiles" consoling his wife after she was injured during a bombing of a TV station.

Towards the end of season 5, Mouch considers retiring from the fire department.

In the Season 5 Finale, Mouch, While trapped inside of a burning factory, seems to be having a heart attack. In the season 6 premiere, luckily, he is back at 51 with all members returning to normal lives. He delivers a moving speech about how close he came to "walking off of this job". he didn't mean that his heart stopped. he had almost gave up on the second greatest thing in his life because he was feeling a little "run down". as he says "while I was lying down on the ground in that burning factory, the one thing I thought about was it wasn't enough". He treasures the time that he has with his brothers and sisters at 51. He hopes he will never have to look down that dark tunnel ever again. He realizes he has not had enough time with Trudy or his coworkers at 51. He signs the whole firehouse second shift up for a Firefighter's muster. he believes that his friends at 51 have been there for him day in and day out no matter what.

In "A Real Shot in the Arm", he and Trudy use their savings to buy out Otis' share of Molly's after his death. Initially unwilling to buy out his shares, he does so after Herrmann reveals to Ritter that he wasn't as much fun anymore since Dawson gave away her piece of ownership and Otis' death meant that his shares would go to his brothers, who want nothing to do with Molly's.

Portrayed by Steven R. McQueen

Firefighter Candidate Jimmy Borrelli (seasons 4 – 5) is the newest Candidate at Firehouse 51 introduced in the season 4 premiere. He comes from a family of firefighters "who drink testosterone for breakfast".^[6] His older brother Danny (Andy Ahrens), a firefighter at Engine 67, pranks him by dousing him with beer, dumping him in the trunk of his car wrapped up with duct tape, and dropping him off at 51 in front of a bemused Chief Boden, Lieutenant Casey, and most of Truck 81. An unimpressed Chief Boden tells Borrelli to go home and never come back to 51 but Jimmy returns to apologize and promises to earn his place. True to his word, he shows himself to be hardworking and dedicated, earning the acceptance of his truck company and the trust of his lieutenant. Casey comments that Borrelli was one of the best candidates he has had on 81 in recent years.^[20] Danny tries to get Jimmy into the same firehouse and is rebuffed by his younger brother. He later explained that he had promised their dying mother that he would protect Jimmy, hence his actions, but stops pursuing the matter after Jimmy explains that he wants to stay at 51 due to the "family" atmosphere.^[20] Like Mills before him, Borrelli was assigned to kitchen duty and menial tasks and occasionally subjected to pranks and good-natured ribbing from the more senior firefighters. For example, Gabby Dawson's brother Detective Antonio Dawson talks him into representing 51 at the "Battle of the Badges" boxing match organized by Mouch, but his co-workers at 51 intentionally leave out the fact that the detective is a seasoned amateur boxer.

Borrelli was attracted to Paramedic in Charge Jessica "Chili" Chilton, and they begin seeing each other until both Lieutenant Casey and Chief Patterson catch them making out and give Borrelli a stern warning about fraternization rules.^[25] Chili tries to brush it off, but Borrelli respects Casey and asks Chili if they could "cool it", to which she angrily accuses him of not being serious in their relationship. Their relationship is further strained after Chili spirals out of control when she starts drinking to cope with the death of her sister and repeatedly refuses help from him or Sylvie Brett. Chili is then fired from 51 and enter rehab and Brett becomes the new PIC. Borelli is transferred to Ambulance 61 as his spot as a Candidate at 51 was under threat due to budget cuts and reshuffling of manpower.

In "Where the Collapse Started", Danny comes over and asks Jimmy for some help with a bar deal. But after Jimmy finds out what's really going on, he refuses. Danny becomes angry and leaves. Later, the house gets a call for a structure collapse where Truck 70 and Engine 67, Danny's company, are already on scene. Danny goes into the building along with Truck 81 and Squad 3 and ignores Jimmy. After the firefighters find and evacuate victims with the building crumbling around them, Severide reports to Chief Boden and he gives the order to evacuate. But Danny believes he heard someone still call out and asks Boden to bring the victim out so he is given one minute. But the roof collapses moments later and Jimmy rushes in. Upon arrival, Jimmy requests Squad assistance for extrication since Danny is pinned but Boden is hesitant. Boden himself then goes inside and pulls Jimmy back just as more debris falls on Danny, killing him. Outside, firefighters, paramedics, and cops line up to form an aisle leading to Ambulance 61 and salute as some firefighters bring out Danny's body and Jimmy leads the way to the ambo. Jimmy then takes some time off after this incident. The next evening, Jimmy shows up at Casey/Severide's apartment and tells Severide that he believes Boden made a mistake by giving Danny one minute that he didn't have. He then storms off after Severide tells him to cool off. In "The Hose or the Animal", he files an official grievance against Boden.

Borrelli returned to Truck 81 in season 5 but the character was written out in the second episode after being injured on the job. He suffered serious injuries to his hand, face, neck and left eye in an explosion. It is implied, based on Dr. Halstead's prognosis, that his career as a firefighter is over.^[26] In the third episode, Boden mentions that Borrelli's family had him transferred to a long-term care facility.
