Entertainment Weekly's Michael Ausiello has the latest on Grey's Anatomy in his spoiler column today. Here's what he has to say about Owen, Cristina, Teddy and Izzie ...

Q: What does Kim Raver’s promotion on Grey’s Anatomy mean for Owen and Cristina?

A: Drama! Despite the emotional smackdown Owen dealt her in the last episode, “From Teddy’s point of view, it’s not over,” Kim Raver said. “But what’s great about Teddy is she’s been in love with him when she was in Iraq and he was engaged and she never crossed that line."

"That’s who she is. Now he’s in love with Cristina, and Teddy has feelings toward Cristina by being her mentor. So that creates a lot of drama and comedy.” Moreover, an upcoming episode finds “Teddy giving Cristina this incredibly [difficult] surgery that she has to do on her own."

"What’s that about?”

Q: Now that Kim Raver is sticking around, when will we learn more about Teddy’s backstory? We know very little about her aside from her relationship with Owen.

A: There’s a scene coming up at Joe’s where Teddy gets plastered and spills her guts to Owen. “A lot is revealed in the bar to Owen,” teases the new cast member.

Q: When is Katherine Heigl returning to Grey’s Anatomy? I miss Izzie.

A: I’ve got good news and bad news. The good news: She’s back on January 21. The bad news?

That episode was shot pre-maternity leave, which means she’ll disappear again for a while.
