It's hard to believe that the Grey's Anatomy Season 9 finale is only two days away (it airs on May 16, 2013), but somehow that's the case. How time flies! Although most details about the finale are being kept under lock and key, we have a general sense of things thanks to some juicy spoilers, which we've gathered here.

It's a two-parter. The finale will span two weeks, taking up both Season 9, Episode 23: "Readiness Is All" and Season 9, Episode 24: "Perfect Storm." The penultimate episode was juicy last week, and we anticipate this one being even more dramatic!

There's a storm. The crises this year will involve a superstorm that knocks out the power (including the rumored explosion, which may happen with a bus) and leaves the docs scrambling to figure out how to treat their patients in the dark.

Someone fights for their life. We know Meredith and her baby find themselves in trouble and one doc fights for their life (could someone really die?). We have a feeling those two clues go together.

Interpersonal drama, too. Chandra Wilson promised there will also be a lot of "personal stuff." It sounds like that includes some more Alex-Jo moments, and one doc getting a big shock.

Callie and Arizona could break up. After Arizona cheated on her wife with hot new doc Lauren (guest star Hilarie Burton) in last week's episode, there has to be some fall-out. We know that Arizona has an awkward run-in with the other woman, but what will happen when Callie finds out? We know there is a "breathtaking" moment that stunned the cast into silence and there is "devastation" in the finale, but just how big will their journey be?

Meredith goes into painful labor! We knew that Meredith would be going in the finale after reading the synopsis, but a sneak peek shows that it is painful (9 out of 10 on a pain scale!) and in the promo, she is rushed to an emergency C-section. One spoiler hints that we should be more worried about the person delivering Mer's baby, so there's another person to be nervous for!

Will MerDer's baby be safe? In the promo, we also see that Meredith and Derek's baby isn't crying. Is this a split-second moment, or is their son really in danger? With Grey's, it could go either way. However, Shonda promises "some job" and a "really beautiful story" for the birth of their son.

April questions her relationship with Matthew. Even though they are engaged — after a romantic, adorable flashmob proposal last week — April is conflicted about their relationship. "We end the season with her in complete and total confusion and incredibly emotional about the confusion," she told The Hollywood Reporter. Basically, she's still confused about Jackson vs. Matthew.

It's worth talking about. Jessica Capshaw calls the finale "thrilling," and says the writers somehow keep making things "more and more exciting;" Camilla Luddington says there's a lot to digest; Ellen Pompeo thinks it's a home run; and Shonda has said she hopes fans will be talking about the finale "all summer long." Does that mean it will end on another cliffhanger?
