Grey's Anatomy Season 9, Episode 17: "Transplant Wasteland" allowed the new world order of the hospital to be established, and it looks like now we can go back to the everyday drama. Which, base on this preview for Season 9, Episode 18: "Idle Hands," is going to be all about the MerDer baby next week.

Apparently Meredith (Ellen Pompeo) is starting to stress, big time, about her baby, which, as the promo puts it, could drive Derek (Patrick Dempsey) a little McCrazy. But we have a feeling all of the worry is going to pay off in an awesome moment when they find out the sex of their baby (OMG yay!).

Here's the synopsis of the episode:

As the hospital continues to make positive changes under the new management, the doctors begin to realize that owning a hospital comes with its own set of problems and responsibilities. Meanwhile, Meredith worries about the wellbeing of her unborn baby, Callie and Arizona try to get the spark back in their relationship, and Alex gives Jo's new boyfriend a run for his money.
