Melanie Lynskey teases Shauna’s dark turn in Yellowjackets season 3

After a nearly two-year break - partly due to last year’s Hollywood strikes, the Showtime series is set to continue its gripping, psychological drama.

Melanie Lynskey, who plays the adult version of Shauna, revealed that the long wait made the new scripts even more exciting. “It felt like things had been percolating for a while,” she told Entertainment Weekly. “It’s so smart, so spooky, and so good. So many things are answered.”

One of the biggest changes this season? Shauna is no longer able to suppress the trauma of her past. The season 2 finale saw her nearly killed by her former teammates, saved only by her daughter Callie—while Natalie met a tragic fate. Now, Shauna must confront emotions she had long buried.

“The first two seasons were about trying to suppress it,” Lynskey explained. “But something was unlocked for her at Lottie’s compound. Once you open that door, you can’t close it again.” Shauna now understands that her emotional detachment is rooted in fear of past losses, but that doesn’t make it any easier to reconnect with her loved ones.

Adding to the tension, Callie (Sarah Desjardins) has become increasingly curious about what really happened in the wilderness. And when Lottie (Simone Kessell) arrives at their doorstep in season 3, Callie is drawn to her—much to Shauna’s horror.

“It’s the most terrifying thing that could happen to her,” Lynskey said. “In Shauna’s mind, Lottie already took her first baby from her—the memory of that baby—and now, she’s back, threatening to take Callie too.”

The weight of it all eventually pushes Shauna to her limits. “She goes off the rails at a certain point,” Lynskey teased. “Christina [Ricci] texted me after reading one of the scripts and asked, ‘Are you okay? That’s going to be interesting.’”

With high stakes and deep emotional conflicts, Yellowjackets season 3 promises to be one of its most intense yet.

The series returns Friday, Feb. 14, on Showtime.
