Grey's Anatomy executive producer Shonda Rhimes said she already has everything planned out for Cristina Yang's (Sandra Oh) exit from the ABC medical drama.

The show's cast celebrated its 200th episode on Saturday night, Sept. 28, and Rhimes spoke to TV Guide about what to expect in Oh's last season. The season 10 premiere on Sept. 26 showed her making out twice with off-again boyfriend Owen Hunt (Kevin McKidd). Cristina ended their relationship last season but told Owen just because she was the one to call quits, does not mean it was easy for her to walk away from him.

There is still a whole season ahead before Oh exits the show, but Rhimes reveals that she has figured out how Cristina will say goodbye. However, the producer declined to comment on whether that means Yang will not survive the season.

"We're all avoiding it tremendously," Rhimes said of the idea of Oh leaving. "It's the back half of the season, so we have 22 episodes to really enjoy Cristina and love her, so we're just going to enjoy ourselves doing what we're doing now."

When asked if Cristina, Owen, Callie Torres (Sara Ramirez) and Arizona Robbins (Jessica Capshaw) will move on and get new love interests, Rhimes replied, "Perhaps, yes...I think it's going to be good."

Rhimes also revealed that season 10 will feature April Kepner (Sarah Drew) and paramedic Matthew planning their wedding. Whether the ceremony actually occurs remains unclear, but Rhimes promised there will be a wedding this season.

"I've been planning one, so I think we're going to see one, yes," she said. "I'm not going to say a word, but we've been making plans for that kind of thing." 

Grey's Anatomy airs Thursdays at 9 p.m. ET on ABC.
