Emma and Hook are getting married in the upcoming musical episode of Once Upon a Time — YAS!

However, we don’t know why, as Entertainment Weekly reports.

Thankfully, EW spoke to Once Upon a Time executive producers Adam Horowitz and Edward Kitsis to get the scoop on the episode, which is set to air Sunday, May 7 at 8 p.m. EST on ABC featuring seven original songs from Alan Zachary, Michael Weiner, and Mark Isham.

“What we can say is that we want to keep the machinations a little bit of a surprise, but that it’s key to Emma’s journey,” Adam said, “the journey that began in the pilot and that we’ve seen throughout the whole series. The singing and the musical is tied directly to Emma… It felt like the right place. Hopefully, when you see how the device works within the episode and how it relates to Emma and her character journey, it all seems to make sense that it would lead up to this. It worked on both a plot and character level, and it allowed us the fun of actually doing a musical episode.”

Edward chimed in: “One of the fun things about a musical is you emotionally say what you’re thinking in song. For Emma, who has been a very guarded and walled-up person, the wedding signifies the growth of her being able to trust someone again and letting her walls down, so we felt like the musical was perfectly a match with that.”

“All the songs in the musical are designed — and we hope this audience feels this way when they watch it — to not be to just stop and have a song; they’re designed to actually reveal character and move the story forward,” Adam added. “Each song is constructed in a way that’s dealing with what’s going on with the characters and what’s going on with the story. We’re trying to move toward something. It builds to that wedding, which — like everything in the episode — we hope is filled with a few other surprises.”
