Zoe Perry might be instantly recognizable as the loving but stern Mary Cooper on Young Sheldon, but long before she became a key player in the Big Bang Theory universe, she popped up on NCIS—and chances are, you missed it. In fact, even die-hard fans of the long-running CBS procedural are often surprised to learn she once suited up for a guest role. So, let’s rewind the tape and uncover the story behind the NCIS character no one remembers—but definitely should.
Who Is Zoe Perry?
If the last name sounds familiar, that’s because Zoe Perry is the daughter of Emmy-winning actress Laurie Metcalf. Yes, that Laurie Metcalf—aka the original Mary Cooper from The Big Bang Theory. Zoe took over the role in Young Sheldon, and her performance has been nothing short of stellar. But her career didn’t start there.
Zoe Perry’s Career Before Young Sheldon
Before landing her breakout role on Young Sheldon, Perry appeared in several high-profile shows including Scandal, Grey’s Anatomy, and The Family. She’s known for her versatility—effortlessly flipping from dramatic roles to comedic timing like it’s second nature. And yes, she also made a stop on NCIS.
The Forgotten NCIS Role: Who Did Zoe Perry Play?
Back in Season 13, Episode 22 of NCIS, titled “Homefront,” Zoe Perry made a guest appearance as Kristin Fields, a police officer with the Harper’s Ferry Police Department. The episode originally aired in May 2016. Kristin wasn’t a major character, and she didn’t return in future episodes, but she played a pivotal role in the case-of-the-week involving a domestic terror plot.
Why Don’t Fans Remember Zoe Perry on NCIS?
Let’s be honest: NCIS has had more guest stars than most people have had hot dinners. With over 450 episodes and counting, it’s easy for one-off characters to slip through the cracks. Zoe Perry’s role was small, and at the time, she wasn’t the household name she is today.
Kristin Fields in ‘Homefront’: What Was Her Role?
In “Homefront,” Zoe’s character, Kristin Fields, provides crucial intel that helps Gibbs and the team piece together the bigger picture of a terror-related case. She plays it straight—a grounded, no-nonsense cop who brings clarity in a chaotic moment. It wasn’t flashy, but it was effective.
The Episode’s Plot in a Nutshell
The episode focuses on a 14-year-old boy who takes down a home invader, but as the investigation unfolds, it’s clear there’s more to the story. Zoe Perry’s Officer Fields provides key evidence and interaction with Gibbs and the team, helping guide the investigation forward.
Perry’s NCIS Role vs. Her Role in Young Sheldon
If you watch Young Sheldon, you know Perry as a Southern Christian mom with strong moral values and a soft spot for her genius son. Compare that to her NCIS role, and it’s a total 180. From nurturing mom to law enforcement? That’s some serious acting range.
The Family Connection: Playing the Same Character as Her Mom
Here’s a cool twist—Zoe Perry and her mother, Laurie Metcalf, both played Mary Cooper, just at different times. Metcalf portrayed her on The Big Bang Theory, while Perry took over in Young Sheldon. That kind of generational casting is rare and poetic, and fans love the real-life tie-in.
Zoe Perry’s Rise to Fame After NCIS
Perry didn’t linger long in the procedural drama world. Shortly after her appearance on NCIS, she landed her career-defining role on Young Sheldon in 2017. From there, her star has only risen. She’s been praised for bringing warmth, strength, and realism to a role already made iconic by her mother.
Why Does This Role Matter Now?
In hindsight, her short NCIS stint serves as a time capsule—proof that even the most recognizable TV stars start somewhere humble. It also shows the kind of range she brings to the screen. If you blinked during Season 13, now’s a good time to go back and appreciate her performance.

What It Says About Casting in Long-Running Shows
