It’s finally May, which not only means flowers blooming, but also spring finales of our favorite shows. Grey’s Anatomy only has three episodes left until its dramatic Season 9 ender, and tonight, May 2, 2013 the penultimate episode is sure to shake things up.

In Season 9, Episode 22: “Do You Believe in Magic?”, which was directed by Kevin McKidd, we’ll see a lot of drama, medical mysteries, and at least one new face. Though you can read all about the episode in our spoiler roundup, we’ll drop a few hints here: Bailey is shutting people out (and shutting down); guest star Hilarie Burton (aka One Tree Hill’s Peyton Sawyer) is stirring up trouble for Arizona (and in turn, Calzona); and two huge cases (a baby with its brain outside of its head and a patient sawed in half) will shake up the hospital.

Basically, everything that happens tonight is ramping up for the next two weeks’ two-part finale, which features a superstorm and the birth of MerDer’s baby. But let’s take this one step at a time and process tonight’s episode. If the spoilers above weren’t enough to satisfy you, you can check out our sneak peek roundup, and then hit the comments with what you’re most excited about!

Catch the next new episode of Grey’s Anatomy on Thursday, May 2, 2013, at 9 p.m. ET/PT on ABC.
