Question: I need some Grey's Anatomy scoop, please!

Answer: In Episode 4, McSteamy and McDreamy cross swords over how to treat a burn victim. And there's no more mystery as to what Diahann Carroll will be doing on the show. According to this spoileriffic ABC promo, she'll be playing as many of us suspected Burke's mom. (That noise you hear is Shonda Rhimes tearing ABC's promo department a new one.)
