Oh, who plays the character Cristina Yang on the hit ABC television show that has been running since 2005. She is one of the last original remaining cast memebers who have stuck with the show over its ten year run. Her character, Cold, cocky and complex, the highly intelligent Yang has always been stubborn and highly competitive — so much so that there was even a brief moment where Yang and her twisted sister Meredith (Ellen Pompeo) were enemies before they cemented one of the most influential friendships in television history.
"Creatively, I really feel like I gave it my all, and I feel ready to let her go," an emotional Oh told The Hollywood Reporter. "It's such an interesting thing to play a character for so long and to actually get the sense that she wants to be let go as well. [Cristina] wants to be let go, and I am ready to let her go. We have to start the process, story-wise, for the Grey's writers to think of why she's going to go."
When asked how the last day on the set of the popular TV show was like, Oh replied:
I will say, my last day, people asked if I was going to be sad. I didn't know. But by the end of the day — which ended up being late since we shot late — Kevin threw me this little party. There was lots of celebration because the party was myself, Tony Phelan and Joan Rater, who left. Gaius Charles [Shane] and Tessa Ferrer [Leah] had left earlier that week. The party was joyous for me — the whole day was. I was so excited to come to work. I came in early, which I never do, and hung out."
Oh was also asked about her potential return to the show when it has its series finale sometime in the future. She mentioned there's always a chance that she could be busy on another project -- which would hinder her from being able to cast her character one last time -- but states she does want to come back to fulfill it one last time.
"We talked about that when I told her I was going to leave but we haven't talked about it again. There are certain things that Shonda and I talk about once and then we leave it because we want things to happen without pressure. I told her, "If you guys want to finish it out however you want to finish it out, I'd be more than happy to come back. And if it doesn't fit in that way, I totally understand. I just want you to know that I'm available." Who knows! I might be doing something fabulous and it might not work out but I did say, "Yes, of course I would."
