Michael Ausiello of TV Guide has some new dirt on what's to come early in the new season of Grey's Anatomy, which begins Thursday, September 27.

By request, we're only posting spoilers after the jump, so fans who desire to be kept in the dark can stay that way. But others remain spoiler hungry, so here's what this insider has to say.

Question: Do you have any good Grey's Anatomy scoop?

Ausiello: Since Preston Burke never coming back, Shonda Rhimes went and got the next best thing: his mama! Yep, Diahann Carroll (pictured) is returning in this season's second episode when she shows up at Seattle Grace to get that choker back from Cristina. Needless to say, her return is shocking â€" and potentially clarifying â€" for Dr. Yang. It's also funny as hell.

In fact, I hear the entire episode is high-sterical. There is also, apparently, some great stuff with Chandra Wilson as Bailey struggles with no longer being the boss lady.

Question: There's a rumor going around that there's a big Mer-Der sex scene set in a shower in Grey's Anatomy third episode. True?

Ausiello: False. Although the word "bathroom" is uttered at least once in the episode.

Question: Have you heard anything about (former Gilmore Girls) star Edward Hermann's character on Grey's Anatomy?

Ausiello: I hear he's playing the world's oldest intern.
