'Grey's Anatomy' 200th Episode Celebration

Fun fact: Every five seconds, someone tweets "Come back to 'Grey's!" to "Grey's Anatomy" alum Sandra Oh. OK, maybe that's not a verified fact. It may even be too conservative a guess.

Oh recently teased fans by tweeting a photo with "Grey's" co-star Kevin McKidd (Dr. Owen Hunt), reviving the perpetual hope that Oh will bring Dr. Cristina Yang back to the ABC series. But before fans could get their hopes too high, Oh posted a link with news on her first post-"Grey's" series regular role -- leading the new BBC America series "Killing Eve."

Here's her "Grey's" reunion photo:

That was posted in May, but it's also the last thing Oh posted before announcing her new gig:

According to The Hollywood Reporter:

"Oh will take on the title role of Eve, a bored, whip-smart, pay-grade security services operative whose desk-bound job doesn't fulfill her fantasies of being a spy. Eve is pursued by Villanelle (uncast), an elegant, talented killer who clings to the luxuries her violent job affords her."

This marks Oh's first series regular role since leaving "Grey's Anatomy" after 10 seasons. She's had other roles -- recurring on "American Crime" and starring in movies like "Sideways" and the recent "Catfight" -- but this is her first full-time gig since playing Cristina Yang, and this time her character has her name in the title of the show. She's her own "person" now, Mer!

Fans replied to Oh's big news with ... dozens of requests for her to return to "Grey's." Sorry, but that's going to be her fate forever, or at least until she agrees to come back for the series finale or some other kind of closure. However, other fans are just happy to see more of this amazing actress on screen:

"Killing Eve" was picked up to series in November, and the eight-episode drama will premiere at some point in 2018.
