As "Grey's Anatomy" season 10 prepares for its return February 27, spoilers regarding the crazy mid-season premiere have fans excited—and worried.

First, it appears that there may be a baby Derek out there in the world, and spoilers confirm that the mid-season premiere may make note of that.

And as Derek contemplates a very special phone call from the President, baby Derek won't be the only thing he and Meredith have to worry about. What will Meredith do if he goes back on his word.

Meanwhile, spoilers also confirm that the mid-season 10 premiere will showcase a response from Jo to Alex's faux-posal.

Sadly, based on this sneak peek, it appears Jo is not ready to get married, and Alex's issues with his Dad are also part of the reason they are not "there" yet.

And that's just the tip of the ice berg for the "Grey's Anatomy" mid-season 10 premiere.

"The first five minutes are so bananas I totally thought it was going to turn out to be a hallucination - but it didn't!" writes Michael Ausiello.

But not all spoilers hint at good thing for "Grey's Anatomy."

Recently, a fan asked Ausiello asked about the fate of Callie and Arizona and whether Calzona will remain together.

Although Ausiello didn't answer outright, he did say the answer lies in a January spoilers update from him.

On January 28, Ausiello pointed out the contract renewal of Ellen Pompeo and Patrick Dempsey, but that the fate of the remaining cast won't come to light until the end of February.

Does this mean the fate of Callie and Arizona relies on whether Sara Ramirez and Jessica Capshaw want to stay on "Grey's Anatomy" beyond season 10?

Well, of course it does. But why point it out?

Is Ausiello hinting at the fact that one of the actresses may not stick around much longer, just like Sandra Oh?
