For the first decade of Grey’s Anatomy, fans were treated to Sandra Oh’s unforgettable performance as Cristina Yang. It’s been five years since her character left the show, but that hasn’t stopped fans from dreaming of her return—even if it’s just for a quick guest appearance. However, Sandra has made it crystal clear that she has no plans to reprise the role anytime soon.

And here's why: Sandra is currently riding high on the success of Killing Eve, a gripping British drama that airs on BBC America. In a recent chat with Extra, Sandra opened up about why stepping back into Cristina Yang’s shoes isn’t in the cards for her. “Nope, not gonna happen,” she said with a smile. “Look, creatively, you grow, you evolve. While I completely get—and deeply appreciate—that fans still adore Cristina and keep her alive through the show, for me, Killing Eve is home now. This is where I belong. I’m Eve, and as long as the show lets me stick around, that’s exactly where I want to be.”

Who Is Eve Polastri?

In Killing Eve, Sandra plays Eve Polastri, a sharp-witted MI5 agent who’s as complex as she is fascinating. Here’s a little backstory: Eve was born in Connecticut but grew up straddling two worlds—half British, half American. Her fascination with crime began early, leading her to excel in criminal psychology. But life took a turn when her father passed away, bringing her back to the U.K., where she eventually met her partner, Niko.

Eve’s career at MI5 wasn’t exactly thrilling. Sure, she assessed risks and assigned protection details, but let’s be honest—she always wanted more. She dreamed of becoming a spy, but instead, she found herself stuck behind a desk, babysitting VIPs during their visits to London. Over time, the monotony started to weigh on her. She felt unfulfilled, restless, and increasingly disconnected from her work. That all changed when Villanelle entered her life.

Villanelle: The Catalyst for Change

Villanelle, played by the brilliant Jodie Comer, is an assassin with style, charm, and danger written all over her. When Eve was appointed head of a secret MI6 unit by Carolyn Martins, her life took a dramatic turn. Investigating a series of high-profile assassinations across Europe, Eve became utterly obsessed with Villanelle. What began as a professional mission quickly spiraled into something deeply personal. So personal, in fact, that Eve ended up getting her hands dirty—literally. She stabbed Villanelle, marking the beginning of a cat-and-mouse game that would forever change both women’s lives.

But what did Eve sacrifice in her quest for excitement? And how does she handle the intoxicating allure of Villanelle’s gaze? These are just a few of the questions fans are eager to explore as the series continues to unfold.

Season 1 of Killing Eve is available to stream on Hulu if you haven’t caught up yet.
