Grey's Anatomy cast members Chandra Wilson and Sara Ramirez recently chatted with TV Guide about what's to come at Seattle Grace - and in the case of the former, what we can expect when she crosses over to Private Practice, ABC's sister show, this week.

“I’m being overprotective of a patient I have that of course their care has to happen in L.A. at St. Ambrose – because that’s the only place it can be in the world,” Wilson joked.

“So I’m heading over to Private Practice!”

Sara Ramirez teased a potential inter-show romantic angle coming our way: “You know, Taye Diggs’ character is single now,” she said of Bailey and Diggs' Dr. Sam Bennett.

Wilson won't bite. “I don’t share stories,” she insisted, laughing.

As for the rest of the Seattle Grace staff? They are about to feel a chill as the result of the merger with rival Mercy West, which will put some doctors' jobs in jeopardy.

Grey's Anatomy stars Chandra Wilson and Sara Ramirez dish on what's to come.

“Not everyone at Seattle Grace is safe,” hinted Ramirez, while Wilson took that theme even further: “Next week is a jaw-dropper. It’s not going to work out for some people.”

Wilson will also be stepping behind the camera as director of the seventh episode of this season Grey’s Anatomy (this week is #5) in a "Patrick Dempsey-centric" episode.

Ramirez says Wilson’s directorial style is the opposite of Bailey's surgery Nazi.

“She was amazing and we all fell in love with her as a director,” Ramirez said.

“There was just a calm, grounded energy about Chandra when she walks in, and everybody just kind of feels it. And it’s so nice and you don’t feel rushed and you don’t feel crazy."
