Charlie Cornwall: The Reluctant Guardian with Everything to Prove

Jessica Green describes her character, Charlie, as someone living her dream — but with a twist. “She’s the guardian, so she’s the protector… but she doesn’t think she’s supposed to be here,” Green explains. Rejected once before by the Library, Charlie has been given a second chance, and she’s clinging to it with everything she has. “She’s not going to let anyone muck it up for her,” Green says with conviction.
What makes Charlie unique isn’t just her sense of duty — it’s her deep-seated doubt. Beneath the tough, serious exterior lies a woman who questions whether she’s truly good enough. “Even though everyone else around her kind of sees that she is, she needs to believe in herself,” Green shares. That mix of strength and insecurity is what sets Charlie apart from past guardians.
When asked what she loves most about playing Charlie, Green lights up — literally. “Each week it’s different,” she says with a smile. From riding horses to fighting while balancing on bikes and performing wire work, the role has pushed her physical limits in the best way. “It’s just really exciting… I get to do all these really fun things that I personally would never get to experience in my life.” And it shows — her action scenes have quickly become fan favorites.

The Season Finale Will Blow Your Mind

While Green is careful not to reveal too much, she promises the final episodes of The Librarians: The Next Chapter are worth the wait. “It’s very action-packed. It’s really exciting. The end has a big twist,” she teases. That twist? Let’s just say it has major implications for season two — which, by the way, is already in production. “I don’t know what I’m allowed to say… You know I’m here, I’m here filming it,” she admits with a laugh. So yes, Charlie fans — she’ll be back.
Though she clearly loves playing Charlie, Green admits there’s one character she’s a bit jealous of: Vikram. “He gets to do whatever he wants,” she says. “Charlie’s quite fierce and stoic… he gets to just be silly and big and out there and reckless.” Watching her co-star Callen Sinnamon embrace the chaos makes her wonder what it would be like to let loose on screen for once. “I envy him sometimes,” she confesses.

One Magical Prop to Rule Them All

The show may deal in magical adventures to the past, but if Jessica Green had her way, she’d skip history class. “I’m going to the future,” she says without hesitation. “I want to see what’s out there. Yeah, take me on a spaceship or something.” It’s a fitting answer for someone who’s clearly forward-thinking — both on and off screen.
Every fantasy series has its share of iconic props, but there’s only one that Green would fight for: the magic door. “It’s mine. I’m taking that. I’m going everywhere,” she says, laughing. While other cast members may have their eye on glowing books or enchanted gadgets, Green knows what’s up. “As if you wouldn’t take the magic door,” she adds with a grin. And honestly? She’s right.
