For the first 10 seasons of Grey’s Anatomy, one of the highlights for fans was Sandra Oh’s portrayal of Cristina Yang, who has been missing in action for the past five years. That doesn’t mean the fans aren’t still clamoring for her to return to the role — even for a guest starring appearance — but Sandra is making it pretty clear that she has no intention of doing so.

No small part of it has to do with the fact that she’s having great success on the British drama Killing Eve, which airs on BBC America. In an interview with Extra, Sandra opened up about the reason we won’t see her return. “No. Creatively, you have moved on and, while I know and I deeply appreciate, because I can feel it from the fans, how much they love Cristina and how the show keeps Cristina alive, for me [Killing Eve] is my home now … this is where I am. I am Eve and that’s where I plan to stay as long as the show will have me, and that’s really where I want to be.”

Killing Eve, which has just begun airing its second season, casts Sandra as MI5 agent Eve Polastri, who is officially described as follows: “Eve is half British, but was born in Connecticut. Always fascinated by women in crime, she excelled in a degree in criminal psychology. When her father died, she came back to the U.K., met Niko, and never really left. Eve started working at MI5 assessing risk, yet never living it. She’d always dreamed of working as a spy, but, instead, she was desk-bound, assigning protection to foreign people of interest during their trips to London. Struggling to find meaning in her work, her ennui began to get the better of Eve, and she couldn’t shake the creeping sense of dissatisfaction.

“Then,” it continues, “Eve’s fantasy crossed her path: Villanelle [Jodie Comer]. Here was an assassin with flare, charisma, and danger. Appointed head of a secret MI6 unit by Carolyn Martins, Eve could now exercise not only her gifts, but also her obsessions. As Eve investigated the string of assassinations across Europe, her fascination with Villanelle grew. Soon it was no longer just a job; it was personal. So personal, she gets blood on her hands: she stabs Villanelle. Eve is far from the desk job now, but what has she sacrificed? And how does her ego react to being caught in the seemingly irresistible gaze of Villanelle?”
