Our favorite show is finally back on the air with a new episode this Thursday and as a result, Grey's Anatomy spoilers abound in E! Online's weekly spoiler Q&A session.

Are Cristina and Owen done? What's the latest on MerDer? How is Izzie doing? Will we see anything new with Callie and Arizona? Without further ado, here goes:

Q: Please tell me more about Meredith and Derek on Grey's Anatomy!

A: Thatcher Grey is not in the hospital because his oldest daughter is getting married. He wants to make amends: He's been sober, and he's working on his steps.

Q: Please give us something about Callie and Arizona on Grey's Anatomy. They have had so little airtime, and we want to know about their relationship. Please tell me there's more to come.

A: Arizona meets Callie's dad (played by guest star Hector Elizondo) in Thursday's episode, and he doesn't take the news of their relationship terribly well. In fact, when Callie's dad tries to get her to move home and she refuses, he cuts off her trust fund.

Q: How's Izzie doing on Grey's Anatomy?

A: As it turns out, cancer is really, really painful. Sigh. Poor Izz.

Q: Any news on when Cristina and Owen will reunite on Grey's Anatomy?

A: Unfortunately not anytime soon. Owen doesn't have time for Cristina anymore (what with his newfound interest in turning George into a trauma surgeon). Actually, to be more specific, Owen's therapist doesn't let Owen have time for her.

Yep, Owen's shrink has given him a specific list of three-word sentences he can say to Yang, but "I love you" is not one of them. Either way, Cristina is not a happy camper.

Q: Got any more Grey's Anatomy scoop?

A: Yes, and it comes from Kellie Martin of ER and Life Goes On fame. Kelly pops up on the small screen in May on both Ghost Whisperer and Grey's Anatomy.

"On Ghost Whisperer, I play a director of a soap opera, and I'm being haunted," Kellie says. "And on Grey's Anatomy, all I can say is that I don't play a patient, and I don't play a doctor. We have to respect the Grey's Anatomy cone of silence. They're very secretive. It's not integral to the crazy rumors going around right now, though."
