Every time ABC shows "American Crime," "Grey's Anatomy" fans react in unison: "Cristina!" Dr. Cristina Yang was a "Grey's" OG, from the first season to Season 10. We're now in Season 13, and Dr. Yang is still very much missed.

Sandra Oh was recently on "Access Hollywood Live" to promote her new movie "Catfight" with Anne Heche, and she was asked about ever returning to "Grey's."

Kit Hoover mentioned a petition out there, with fans pushing creator Shonda Rhimes to bring Oh back as Cristina. "Really?" Oh replied, sounding surprised. "I gotta tell you right now, I'm so happy to promote 'Catfight.'" She laughed. "Having said that, every so often... As an actor, as an artist, it's a full life that one has. And as I look back to that time -- which is extremely important and deeply meaningful to me -- and it means a lot to me that a whole generation, a new generation of fans are discovering the show. So it means a lot to me."

Hoover pressed: Would she go back? Oh admitted, "At this point... No, I don't think so." What about at the end of "Grey's," for the series finale? "I had spoken to Shonda about that," Oh said. "But I just don't know. It would have to feel right."

So you're saying there's a chance?

Sounds like she might pull a Nina Dobrev and just come back for the finale. If so, we can live with that. (But can Owen? He needs you, girl! And you're still Mer's person!)

Watch Oh discuss "Grey's" at the very end of the clip: "Grey's Anatomy" Season 13 airs Thursdays at 8 p.m. on ABC. "American Crime" Season 3, co-starring Sandra Oh, premieres March 12. The movie "Catfight" will be available through VOD and in a limited theatrical release on March 3.
