Grey's Anatomy Spoilers: Another Izzie absence and the Chief falls off the wagon!

Ausiello posted a couple spoilers about Izzie’s “pregnancy” and a major setback for the Chief!

Question: Is Izzie really pregnant on Grey’s Anatomy? —Elle
Ausiello: I’ll say this: ABC’s promo gurus are very sneaky! While we’re on the subject of Katherine Heigl, sources confirm to me exclusively that she’s taking another leave of absence from Grey’s — but this time her reasons are personal not professional. Heigl will be going on a belated maternity leave to spend some QT with new daughter Naleigh. As a result, Izzie will be MIA for another string of episodes (most likely in early 2010.)

Question: Please tell me something will happen soon on Grey’s Anatomy that will make me stop hating the Chief! —Ann
Ausiello: Would the sight of him falling off the wagon do the trick? ‘Cause that’s what happens at the end of this week’s episode.
