When Miranda Rae Mayo first stepped into Firehouse 51 in February 2016, she arrived as a promising new addition to an already beloved ensemble.

A decade later, her character, Lt. Stella Kidd, stands as one of the emotional pillars of Chicago Fire — and as NBC prepares for a sweeping One Chicago crossover event,

the milestone feels both deeply personal and professionally monumental.

Ten years in network television is no small feat. In an industry often defined by unpredictability and rapid turnover, longevity speaks volumes. For Mayo, now 35, the anniversary isn’t just about screen time — it’s about growth, community, and the rare experience of landing in what she affectionately calls an “incubator of love.”

“This is really incredible in a multitude of ways, and I just feel really blessed,” Mayo reflects. “I’ve lived in Chicago and been in community with this cast and crew, and I just feel really lucky that I landed here. The entertainment industry can be a precarious, dicey place depending on where you land. I was really, really fortunate.”

From Rookie to Leader

When Stella Kidd first appeared, she was introduced with built-in emotional credibility — a friend of Gabby Dawson (played by Monica Raymund) from their fire academy days. That early connection was no accident.

Former showrunner Derek Haas reportedly understood the delicate art of introducing new blood into a tight-knit ensemble. By tethering Stella to an established and beloved character, the series eased viewers into trusting her.

And trust they did.

What began as a confident but relatively untested firefighter evolved into one of the most compelling leadership journeys on network television. Over the years, Stella has navigated harrowing rescues, personal heartbreak, professional doubt, and ultimately, promotion to lieutenant — a role that carries both authority and emotional weight.

Fans have watched her wrestle with imposter syndrome, shoulder the responsibility of command, and fight for her place in a historically male-dominated field. Her rise has mirrored real-world conversations about representation and resilience, adding depth to the drama beyond its explosive rescues.

Lessons in Duty and Sacrifice

For Mayo, portraying Stella has been transformative.’

“I have learned more about commitment and sacrifice and duty from her and from this cast and crew of people, I think, than from anyone in my life,” she says.

That sentiment underscores the unique bond formed on long-running procedural dramas. Firehouse 51 isn’t just a fictional workplace — it’s a space where actors spend months each year reenacting life-or-death scenarios. The emotional intensity bleeds into real camaraderie.

Stella’s unwavering sense of duty — whether charging into burning buildings or mentoring younger firefighters — has resonated with viewers seeking strength and steadiness. Mayo often hears from fans who see Stella as a symbol of courage.

Some, she shares, even borrow her name as a rallying cry.

“My parents text me, ‘You got this, Stella Kidd,’ if I’m nervous about something,” she laughs. “That makes my heart swell.”

It’s a testament to the character’s reach — and to the layered humanity Mayo brings to the role.

The ‘Incubator of Love’

Long-running network shows can be pressure cookers. Grueling shooting schedules, high expectations, and evolving storylines test even the most seasoned actors. Yet Mayo describes her decade on Chicago Fire as grounding rather than draining.

Chicago itself has played a starring role in that stability. Unlike productions based solely in Los Angeles, filming in the Windy City has cultivated a tight-knit community atmosphere. Cast and crew live and work alongside one another, forging bonds that extend beyond call sheets.

Mayo credits that environment with helping her mature both personally and professionally. The phrase “incubator of love” isn’t hyperbole — it’s a reflection of a set culture that nurtures longevity.

In an era when many shows struggle to maintain core casts, Chicago Fire has managed to preserve a sense of family. Even as characters come and go, the foundation remains intact.

And Stella Kidd stands firmly at its center.

A Crossover of Cinematic Proportions

As Mayo marks her 10-year milestone, the timing couldn’t be more dramatic. NBC’s upcoming three-show One Chicago crossover — spanning Chicago Fire, Chicago Med, and Chicago P.D. — promises a high-stakes narrative that feels “movie-like” in scale.

Crossover events are logistical feats. Coordinating multiple casts, intertwining story arcs, and sustaining tension across consecutive hours requires meticulous planning. For actors, it also demands emotional agility — shifting tone while maintaining character continuity.

For Stella, a crossover often means amplified responsibility. Firehouse 51 frequently serves as the ignition point for crises that ripple outward, drawing in surgeons and detectives as emergencies escalate.

While details of the upcoming event remain tightly under wraps, anticipation is mounting. Crossovers historically deliver some of the franchise’s most intense moments — from mass-casualty incidents to moral dilemmas that test every department.

For Mayo, participating in such events underscores how far the series has come.

What began as a standalone firefighter drama has evolved into a sprawling, interconnected universe. And Stella Kidd has grown alongside it.

Representation That Matters

Beyond explosive action and interdepartmental drama, Stella’s journey carries cultural significance. As a woman ascending to leadership in a high-risk profession, she embodies both vulnerability and strength.

Her storylines have tackled themes of mentorship, trauma recovery, and navigating power dynamics. Viewers have witnessed her support other women in the field while asserting her authority with quiet confidence.

In an industry where female characters in procedural dramas can sometimes be sidelined, Stella’s trajectory has been refreshingly central.

Mayo approaches that responsibility with humility.

“There are a lot of people who really love and appreciate this character, and it’s kind of overwhelming in a beautiful, wonderful way,” she says. “She really is such a wonderful character.”

That appreciation isn’t lost on fans who see Stella not just as a fictional firefighter, but as a symbol of perseverance.

Looking Ahead

Ten years is both a milestone and a springboard.

As the One Chicago universe braces for its next major crossover, Stella Kidd remains poised at the heart of the action — seasoned yet still evolving.

Mayo, for her part, radiates gratitude rather than complacency. In an entertainment landscape that can shift overnight, she recognizes the rarity of her journey.

From her tentative first days on set to commanding scenes as lieutenant, she has grown in tandem with her character. The fires have gotten bigger. The stakes have gotten higher. But the core — commitment, sacrifice, community — remains unchanged.

And as fans prepare to tune in for the franchise’s latest cinematic spectacle, one thing is certain: Stella Kidd isn’t just part of Chicago Fire’s history.

She’s part of its future.
