Justin Hartley and Sofia Pernas have delighted fans with their on-screen chemistry in the hit CBS drama Tracker, marking their third collaboration. But their shared journey on screen started years before. Let’s explore all three shows where this real-life couple co-starred—and what their evolving partnership means for audiences.
1. The Young and the Restless (2015–2016)
Where it all began.
Their connection first sparked nearly a decade ago on the long-running daytime soap. Sophia Pernas joined as Marisa Sierras, the on-screen love interest of Hartley’s character, Adam Newman. Working closely together for approximately a year, they developed both professional rapport and personal friendship—that professional foundation would prove essential later on.
2. Quantum Leap (2022)
A reunion and a fresh dynamic.
Their second on-screen reunion was a guest appearance on the NBC reboot of Quantum Leap. In early 2022, Pernas featured in an episode alongside Hartley. The project allowed them to showcase a playful, creative dynamic off-screen. Pernas reflected: “It’s play. It’s not work,” highlighting how acting together organically strengthens their connection.
3. Tracker (2024–Present)
Their latest and most compelling collaboration.
Now co-starring in Tracker, Hartley plays lead Colter Shaw, with Pernas returning as Billie Matalon, a rival tracker and former love interest. This series enriches their on-screen relationship with layers of tension, shared history, and subtle romantic tension.
Their performances in Tracker reflect genuine intimacy and familiarity. Sofia described how returning as Billie deepened the emotional stakes: “We love working together… I bounce things off her all the time,” Hartley said. Critics and fans have praised the strong, natural chemistry they share when scenes shift between conflict, flirtation, and vulnerability .
