It’s finally April’s big wedding day, and she is Freaking Out, capital letters absolutely necessary — what, did you think there was any possible way April Kepner would turn out not to be a Bridezilla?

And just in case you happened to miss any part of this week’s Grey’s Anatomy episode, also known as the last one of 2013, don’t worry, we’ve got you covered.

Here’s what you need to know about Season 10, Episode 12: “Get Up Stand Up.”

Cristina accidentally made medical history. Remember the groundbreaking surgery she was working on in last week’s episode? She was successful, and now she’s the talk of the medical community — like, photo shoots, press conferences, nominations for Harper Avery awards… no big. This is what Cristina’s worked for her entire career, so why is she clamming up in front of the cameras? One simple reason: her procedure failed, but her patient’s still alive, and she has no idea how to explain what she did.

Alex finally gains closure with his dad… and it’s a good thing, too, because by the episode’s end, Jimmy’s life is hanging in the balance. After telling his dad it was a good thing he left, because his life turned out way better because of it, Alex headed out to the wedding. But while he was gone, Jimmy’s condition went south, and Shane — who’s getting a pretty big head around here — decides he’s skilled enough to operate, no attendings necessary. What’s that we hear? it’s the bad idea train coming ‘round the bend.

Ultimately, Richard has to run in and save the day after Shane royally flubs the surgery and has a Heather-themed guilt meltdown, but the fate of Alex’s dad won’t be revealed ‘til February. Spoiler alert: it ain’t lookin’ good. Ugh!

We finally get answers about why Arizona cheated… and although we’d never condone adultery, everything does make a little more sense now. When Arizona met Lauren, it was after her accident, which means that someone found her attractive, sans one leg. But Callie was attracted to her the way she was before, and Arizona’s worried she won’t be now.

Meredith and Cristina fight to the death. And is it just us, or can you practically feel your heart cringing every time these two trade insults? But guess what — just before the wedding, they finally clear the air. Cristina feels alone, and Meredith is jealous that Cristina is able to selfishly pursue her dreams. There might be hope for our favorite BFFs yet.

Alex all but proposes to Jo with a makeout sesh and a romantic speech about how he wants to stay with her forever and have kids with her and be each other’s family. Can this couple please last? Shonda Rhimes, we’re looking at you.

Derek is being courted by a group working on a presidential initiative on brain mapping, but even after a presentation and the offer of what is insinuated to be insane gobs of cash, he turns them down. He’s Daddy Derek right now, not World Class Surgeon Derek, remember? You know, ‘til he gets a call from his old buddy Barack in the middle of the wedding. We’re not sure exactly what went down in their conversation yet, but would you say no if the president asked you to do something?

April’s wedding is beautiful and in every way a picture perfect Pinterest barn wedding. And not only does April look gorgeous, but bridesmaids Arizona, Meredith, and Cristina do too. Why is it that bridesmaids dresses are so much less awful in TV weddings?

And despite her freak out, her wedding goes off without a hitch… til Jackson stands up and confesses his love for her in front of everyone, including his girlfriend Stephanie. We’d hate to say we totally saw this coming, but… we totally saw this coming.
