Sylvie Brett is a paramedic assigned to Ambulance 61, introduced during Season 3 as Leslie Shay's replacement. Originally from Indiana, Brett quickly proved herself as a competent paramedic in the field. She was assigned to the position of Paramedic in Charge (PIC) after Chili was fired.

Biography[edit | edit source]

She was born to a teenage mother named Julie, who gave her up for adoption.

Her adoptive parents raised her on a farm in Indiana. They later had a son who became Sylvie's adoptive younger brother.

When Sylvie was a teenager, she was raised by her aunt Ann due to her mother's nervous breakdown.

Season 3[edit | edit source]

Sylvie joins the firehouse as a replacement for the deceased Shay. Initially, Dawson was cautious when working with her, but they quickly became best friends. However, when the house gets toned out for a call and Severide first sees her after returning from over a month-long break, he does a double-take while she's walking away from him, noticing the resemblance between her and Shay. This then escalates to the point where he tries to hang out with her, using her to get past Shay since they look alike. It takes him a long time to get past this until he gets married to Brittany.

Sylvie tells the house that she ran away after getting cold feet before her marriage. However, her husband to-be finds her working at 51 and comes to visit her. He apologises 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, as well as assuming that she was going to move in with him after getting robbed. She tells him she's happy in Chicago, but he tells her she isn't. She breaks up with him again and he leaves.

Sylvie joins the best rated Zumba club she found on Yelp 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, but she ends up telling Casey due to his misunderstanding of the relationship of the two. She asks if he keep can it a secret, but he ends up telling it to Dawson, then Hermann, then Mouch, then everyone else. Cruz then asks her out and she rejects him. However, she accepts sometime later, and they start dating.

She's partnered with Peter Mills, who replaced Dawson as Paramedic in Charge, on Ambulance 61. They go on a call to help a teenage boy who was drowning and appeared to be stable when placed in the ambulance. However, on the ride to the hospital, he suffers from a pulmonary edema because of secondary drowning. He's pronounced dead not long after he arrives at the hospital. The boy's father is Papa Lullo, a senior mafia member. He turns up at the firehouse blaming Mills for his son's death. (Arrest in Transit)

Soon after this, Mills and Brett are called to help a man injured by a fall down a back ally. However, things seem suspicious when they get there as he wasn't injured by a fall, but run over and there's a vehicle blocking one of the ally's exits. Before they can load him into the ambulance, some of Lullo's men show up and kidnap them. It's hours before the station notices. (Santa Bites)

In the car, Brett and Mills both fight their kidnappers, causing the car to crash. Everyone survives the crash, but one of the kidnappers is severely injured and in need of medical attention. They're forced at gunpoint to try and save him without going to the hospital. Brett tells Mills to clamp where he shouldn't to let one of the captors die, but neither can go through with it. They manage to escape from their captors, but get themselves trapped. They're eventually rescued by Firehouse 51 and Jay Halstead. (Let Him Die)

She is upset that Mills has chosen to go to North Carolina near the end of Season 3 and during his goodbye party, she breaks down in tears and hugs him goodbye.

Season 4[edit | edit source]

During a call, Sylvie gets attached to a baby she delivered to a gunshot victim mother who died in the ambulance. She visits the baby in the hospital several times until Chief Boden finds out and tells her to let it go, as 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 receptionist is out. She goes to see him and tells him about his son, but he ignores her. However, when she comes back to see the baby yet again, the father is there and he thanks her.

She and Chili also help host a wedding, where she sings.

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.

Season 5[edit | edit source]

Both Chilli and Jimmy leave as paramedics, leaving Dawson to return to her old spot and work alongside Brett. During one of the cases, Dawson's brother Antonio shows up and she instantly develops a liking towards him. After some consideration, she asks him out, but he refuses, saying that his breakup with his ex-wife is still on his mind and he doesn't want her mixed up in it. She responds by saying that she doesn't mind and as a result, they start going out.

She tries harder to impress Antonio's son Diego, who likes to play chess and whom she doesn't connect with. Otis teaches her how to play and Antonio later asks her to take care of Diego when he's suddenly called to work. She agrees and she and Diego are at the firehouse when Antonio's ex-wife, Laura, shows up abruptly and asks Diego to wait for her while she harshly tells Brett that she doesn't trust her and doesn't want a girl like her around her son. This upsets her and when Antonio shows up, she tells him what happened and he apologises. She adds that she doesn't want to be in the middle of his fight with him and his ex-wife and he tells her that he warned her before this, 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 her door and apologises, but she is still angry. She later tries to get her mind off Antonio by doing extra exercise at the firehouse, trying to find online makeup classes, 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.

Season 6[edit | edit source]

She helps Cruz develop his Slamigan tool by making prototypes using her welding skills to weld the halligan and sledgehammer together (Slamigan).

Cruz freaks out over her safety after she and Dawson agree to help Antonio and Voight. They distract a patient whose house they have been called to three times prior under the pretence of doing a wellness check while a cop sneaks in the back door to clone the man's laptop. When there is a knock on the door, Brett hides a scalpel behind her back just in case. Back at the firehouse, she overhears Cruz arguing with Otis about Antonio putting her in danger. Cruz later apologizes (Hiding Not Seeking).

In Looking for a Lifeline, Sylvie has a pregnancy scare and Dawson takes her to buy a pregnancy test at a drugstore. When Antonio comes by, Brett tries to tell him, but just starts crying instead. She tests negative, but seems to have mixed feelings about it (The Chance to Forgive). Before Dawson leaves for Puerto Rico, Brett has a fight with her about Dawson not respecting her rank during a call.

Season 7[edit | edit source]

Sylvie dates a man named Kyle Sheffield, a chaplain with the CFD and a friend of Foster. However the pair break up, Kyle citing that their relationship has led to firefighters not willing to confide in him after Brett asks him to talk to Casey about a bad call he experienced. ("Fault in Him")

She has difficulty moving on from him and sympathizes with Casey on the subject of tough break-ups. She then attempts to help him out by setting him up with her spin class instructor, Olivia.("Try Like Hell".

After a game night with their friends, Olivia says Casey is great, but that Brett should be the one dating him as the two were "meant for each other". Later, Brett confides this to Foster and Kidd, who seem to agree with Olivia's assessment and leave Brett feeling confused about her feelings towards Casey.

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 she misses her life in Chicago and isn't happy in her new quiet life with Kyle, so they break up. ("I'm Not Leaving You")

Season 8[edit | edit source]

Sylvie leaves with Kyle following the boiler explosion in season 7.

She returns to Station 51 in Badlands.

In Off The Grid, her biological mother wants to make contact and she has mixed feelings, but ultimately goes to see her. She realizes that she couldn't do it alone and asks Casey to come with her for support. After a terrible meeting with her stepfather Scott, she believes she made a mistake. While at the Firehouse, Capp tells her she has a visitor and she is approached by her birth mother, Julie, who apologizes for her husband's actions and reveals she is pregnant with her second child. Shocked, she listens as Julie tells her that she tracked her down because she wanted to make a connection with her before giving birth and have her in the child's life.

During The Tendency of a Drowning Victim, Brett spends time with Julie, who is happy at getting to know her and teases her for her obvious feelings for Casey. They soon believe that she is about to have the baby, but it turns out to be a false alarm, although the pair are still happy with the chance to talk more.

In Protect a Child, Brett continues to bond with her mother by helping her house shop.

On ''I'll Cover You'', she finds herself at the hospital with her biological mother giving birth. Unfortunately, Julie does not make it through the birth; however, the baby does. Brett became the older half-sister of a little girl.

In Light Things Up, Sylvie is unable to come to terms with the fact that her mother has died, but attends the funeral with her adoptive family in attendance. She later goes to the hospital to check on her half sister and see if she is doing fine. She is dismayed to see that a riot has broken out at the fire house due to the closing of another house. Her stepfather Scott nearly forces her to care for the child or he'll give her up, but she later finds him at the hospital, outside his child's room pacing. After a talk, she convinces him to keep the child after seeing his concern for her and offers to help him in anyway she can.

In 51's Original Bell, Brett is pleased to see Scott has decided to keep the baby and named her Amelia, which was her mother's middle name. Scott announces he will move back home, but tells Brett to visit and be a part of her little sister's life. At the end of the episode, she is at Molly's when Capp returns and joins in the celebration for him.

Season 9[edit | edit source]

In Rattle Second City, Brett and the squad welcome new paramedic Gianna Mackey, a friend of Cruz. She is amused when Cruz is late to introduce her. She takes Mackey on a call, with both finding a man who has overdosed. While tending to him, a gun is held to her head by the man's brother, who threatens them to help him or die. She keeps her cool and talks him down before taking the brother to the ambulance to transport him to the hospital. Afterwards, she learns from Kim Burgess that the brothers are heavy criminals. She later hears the younger brother died and worries about the elder one taking revenge. She worries about him stalking her, especially when she finds her apartment door open. Not taking any chances, she calls Casey and he decides to sleep over to protect her. She and Casey spend the time joking around by playing games and having a good time. Much later, she and Mackey are called out and her stalker appears behind them in his car, ramming them off the road.

In That Kind Of Heat, Brett and Mackey are shown to have survived the crash, but are trapped inside the overturned ambulance. After breaking free, they wonder if the gunman is still out there. They are soon rescued after Casey and Truck 81 show up. They find the stalker trapped in his car, begging for help. Despite his actions, Brett frees him and gets him the medical attention he needs.

In Smash Therapy, Brett and Mackey become close, especially when the latter allows Brett to destroy a drone (that seriously injured a woman) to vent her frustration. Brett thanks her for this and gives her encouragement in pursuing Gallo.

During Blow This Up Somehow, Brett goes to see Chief Boden, who is with Chief Coulson, the head of paramedics. Coulson reveals that a man Brett and Mackey treated had no trace of the drugs they gave him and accuses Mackey of stealing them from the ambulance. Shocked, Brett immediately jumps to her defence by denying this. At Molly's, she discusses the situation with Mackey and Cruz. After Cruz mentions a patient stealing drugs from a paramedic, Brett realizes that the people who called about a seizure were actually scam artists and that they stole the drugs after distracting them with the case. The pair then work together to find the real thieves. After doing so, Brett and Mackey tell the other paramedics that they were conned and Chief Coulson and the police arrive to arrest the culprit, who had the drugs in their pockets. Afterwards they celebrate at the bar, where Mackey expresses her gratitude to Brett for believing in her and Brett tells her she will always have her back, but jokingly leaves her to deal with Cruz, who has found out about her and Gallo.
