Annabelle Toomey is the breakout star of The Pitt, delivering a haunting performance as Kylie Conners. But her rise didn’t happen overnight—here’s how her roles in Chicago Fire, Chicago P.D., and beyond set the stage for her biggest moment yet.
Annabelle Toomey is the name on everyone’s lips this season, thanks to her gripping portrayal of Kylie Conners on The Pitt. The young actress has taken a complex, emotionally charged role and turned it into a career-defining moment. But this isn’t her first time leaving a lasting impression—Toomey has been quietly building a resume that proves she’s one of Hollywood’s most promising young talents.
The Role That’s Turning Heads: Kylie Conners on The Pitt
Toomey’s character, Kylie, arrives in The Pitt under mysterious circumstances. Brought into the ER with a laceration and a chipped tooth, her injuries quickly raise red flags for the medical team. Bruising across her body and blood in her urine suggest something far more sinister than a simple fall. As the season unfolds, Kylie’s high pain tolerance—she doesn’t flinch even when poked with a needle—has led fans to speculate she may have Congenital Insensitivity to Pain, a rare condition that renders sufferers unable to feel physical pain.
This isn’t just a medical drama subplot. Kylie’s story taps into deeper themes of trauma, resilience, and the failures of systems meant to protect children. Toomey’s ability to convey quiet strength and vulnerability has made Kylie one of the most compelling characters of the season. Her performance is a masterclass in restraint, letting silence and subtle expressions speak volumes.
From Chicago Fire to Chicago P.D.: The Roles That Proved Her Range
Before The Pitt, Toomey was already making waves in the One Chicago universe. Her first major television role came in 2024, when she played Harper in Chicago Fire’s 12th season. Harper, a troubled girl hiding in a closet during a fire, became a focal point in an episode that explored the aftermath of divorce and the dangers of childhood neglect. Toomey’s portrayal was so nuanced that it left viewers—and critics—taking notice.
But it was her 2025 arc on Chicago P.D. that truly showcased her range. As Marie Pappas (also known as Zoe Cassidy), the kidnapped daughter of a serial killer, Toomey delivered what co-star Patrick Flueger called a “stellar” and “almost intimidating” performance. Zoe’s harrowing journey—from being abducted by her father to leaving clues for her rescuers—required Toomey to navigate intense emotional terrain. Fans and critics alike raved about her ability to convey fear, resilience, and quiet defiance, often with just a glance.
Her work in the One Chicago franchise didn’t just earn her accolades; it proved she could hold her own in high-stakes, emotionally demanding roles. This was no small feat for a young actress, and it set the stage for her breakout moment on The Pitt.
A Versatile Young Talent: From Dopesick to The Bear
Toomey’s resume is already impressively diverse for an actress her age. She made her television debut in the 2021 miniseries Dopesick, playing Thompson and Catherine Brownlee. Though her role was small, it was a significant first step into the industry.
Since then, she’s appeared in two of the most talked-about series of the past few years:
- The Bear: Toomey played Eva in four episodes of the Emmy-winning series, holding her own alongside powerhouse actors like Oliver Platt and Sarah Ramos. Her ability to blend into the show’s chaotic, high-energy environment while still making an impact spoke volumes about her adaptability.
- Mayor of Kingstown: As Molly, Toomey appeared in six episodes of the gritty drama, further proving her ability to tackle complex, layered roles in mature storytelling environments.
Each of these roles required something different from Toomey—whether it was the quiet intensity of Dopesick, the fast-paced chaos of The Bear, or the dark, dramatic tone of Mayor of Kingstown. What ties them together is her ability to disappear into her characters, making each performance feel authentic and lived-in.
Why Annabelle Toomey Is the Next Big Thing
Toomey’s rise isn’t just about talent—it’s about timing. In an era where audiences crave authentic, nuanced performances, she delivers exactly that. Her roles in Chicago P.D. and The Pitt have shown she can handle heavy, emotionally charged material with the skill of an actor twice her age. Meanwhile, her work in The Bear and Mayor of Kingstown proves she’s versatile enough to thrive in any genre.
But what truly sets her apart is her ability to make viewers feel. Whether she’s playing a victim of abuse, a troubled child, or a kid caught in the middle of a crisis, Toomey brings a depth to her characters that lingers long after the credits roll. It’s no surprise that fans of The Pitt are already clamoring for more screen time for Kylie—or that industry insiders are taking notice.
With The Pitt still unfolding, there’s no telling where Toomey’s career will go next. But one thing is certain: she’s not just a rising star. She’s already here.
