ThisOnceis going for a musical wedding episode, which can be scary.

For this to work, I need you to check your magical plot doubts at the door.

I need you to not bethatfriend who sawLa La Landand insisted that Emma and Ryan cant actually sing.

I need you to root for Zelena with me.

Lets grade these numbers and this wedding together and talk about the MAGIC OF SONG.

In the present, Snow asks Emma which dress shes decided on, but she hasnt decided.

Fortunately, Belle found Snows old dress in the back of Rumples shop.

The next morning, a whistling bird shows up, launching everyone into MUSICAL VERSE.

Its the moment of truth Snow does fine, but David… David has pipes, yall.

They decide together that the most powerful weapon they have is song.

And like I said, their voices are great, but is it enough to beat the Evil Queen?

I mean, cmon.

Back in the present, Emmas sipping on mimosas when Snow shows up with her dress.

Emma loves it, but as soon as she touches it, it turns to black.

Naturally, she hates that everyone is singing.

And how do you convey your hatred of song?

Through BROADWAY-THEMED ROCK MUSIC and light grinding on mirrors.

All she says is that she loves him.

But back in the Enchanted Forest, Snow and Charming run into Hook.

IT LAUNCHES HIM INTO SONG.

Hook gets a pretty wonderful Queen-inspired number about revenge… on the crocodile that snagged his hand.

As everyone knows, all people with an accent can sing, so we dont even question Killian.

Of course, in present day, Hook has an even bigger obstacle helping Emma defeat the Black Fairy.

He goes to address things with Rumple, who isnotapologizing for lying about the Black Fairy.

So Hook shoots him with dream shade from Neverland.

In the process, he finds her orphan music, but Emma shuts it down real fast.

Whos willing to bet that its her own music that brings her back to life??

As the music starts, Rumple fakes us out becausethe Dark One doesnt sing.

But in this episode, she is the Beyonce to Reginas Kelly Rowland.

Back in Storybrooke, Regina and Zelena have isolated the freezing portion of the spell.

Emma attempts to stop her, but she makes Emma remember what its like to be alone.

By playing that song she once recorded on her tape recorder.

Henry, being the most logical adult on this show, gives Emma a pep talk.

Of course, she did it with Zelenas help, and Regina sends them home.

Which one, pray tell?

Probably the one with the Black Fairy!

She just has to let it bubble to the top.

But he discovers a surprise page that reveals the moment Blue placed all that song inside of Emmas heart.

She rips it out, but shecant kill her.

No matter what Robin Thicke may have led us to believe, its nearly impossible to kill song!

Happy Beginning Ensemble: C

Fittingly, Emmas song is nearly a perfect addition toOnce.

Emma realizes her power mid-song, discovering how strong she can be whilealsorealizing that shes not alone.

Henry picks up her heart and shoves it back into her chest, but the Black Fairy isnt done.

Even so, its time for the wedding weve all been waiting for.

With Archie officiating, Emma is walked down the aisle to Hook with Snow and David on hand.

Its been a long time coming, guys, but we get our wish Swan and Hook are married.

They spend their first dance singing their own song, and eventually the group joins in.

Its a nice number about how this isnt a Happy Ending but a Happy Beginning.
