He’s Stealing Hearts (and Scenes): Meet Chicago Fire’s Witty Young Actor
To say that Chicago Fire power couple Kelly Severide (Taylor Kinney) and Stella Kidd (Miranda Rae Mayo) have navigated a rollercoaster
parenting saga is an understatement. The bright side? Amidst it all, Mayo tells NBC Insider that she’s had a blast with her new co-star, Hero
Hunter, who’s recently joined the drama as an important part of Stellaride’s ongoing journey.
What began as a turbulent adoption process eventually led to a delightful pregnancy discovery, but after Stella was revealed to have miscarried in the Season 14 premiere, the couple thought their chances of becoming parents were slim. But after learning that a teenage foster child named Isaiah, played by Hunter, needed a home, the 51 firefighters wasted no time opening their doors, exploring a new chapter as foster parents.

In an exclusive interview, Mayo opened up about exploring the storyline with Hunter and Kinney throughout Season 14. Confessing that her young Chicago Fire co-star has “the most iconic name,” the actress gushed over how much of a delight it’s been to work with the One Chicago newcomer.

“He’s so smart, he’s witty, he cracks jokes. He belongs on a set,” Mayo told NBC Insider. “I’m so excited to follow up and see all of the inevitable success that he creates for himself. But he has great instincts. He’s a joy to be around.”

Miranda Rae Mayo breaks down Stellaride’s “whirlwind” parenting journey on Chicago Fire
While Stellaride has been thriving as foster parents, it came right after a troubling development in their relationship with the loss of their baby. The couple has navigated a truly whiplash-inducing chain of events.
“She was definitely not looking to be a foster parent, and so it all happened kind of in this whirlwind way,” Mayo told us. “But Stella being who she is, and Kelly being who he is, this kid needed somewhere to go. And they met him, and he was wonderful, and so they said, ‘Come on in.’”
Mayo added, “That’s just the kind of people they are. When somebody needs help, they’re there. And that’s just the overall theme of our show, and everybody at Firehouse 51.”
