Rose is carrying Derek's child?! Grey's Anatomy fans who caught the brand-new promo for Season 5 were not the only ones caught off-guard by this baby bombshell. But is it bona fide, or culled from a dream/nightmare sequence?

Grey's creator Shonda Rhimes explicitly said in a May podcast that while one of the couples who locked lips in the Season 4 finale soon might find themselves in a family way, "Rose will not be pregnant." And Rhimes is sticking to that testament. Responding to the rabble-rousing TV promo, she tells EW's Ausiello, "I would not deceive our fans, especially those loyal enough to listen to our podcast."
