(We're just going to pause here for a second to let that glorious news sink in and for the subsequent screams of excitement die down. All good? Great! Now take another deep breath and keep reading…)
ET had the pleasure of visiting Once Upon a Time's set in Vancouver, Canada, last month during filming of the musical matrimony, and we asked the star-studded cast what their initial reaction was after discovering that Emma and Hook would be tying the knot in season six's penultimate episode.
"I thought it was perfect," Jennifer Morrison gushed to ET during a joint interview with co-star Colin O'Donoghue. "We just felt, like, what better way to make it feel extra special than to have [the wedding] also be the musical episode?"
From recording the original songs, to learning the choreography and finding the inspiration for her wedding gown, (more on that later!) Morrison revealed that working on the musical episode has been a career highlight.
"It's been so fun!" the 38-year-old actress exclaimed. "I mean, I feel like I just keep repeating myself: It's just so fun! it's just so fun!"
"You're going to have a whole article of Jennifer saying, 'It's just so fun!' over and over again," O'Donoghue said with a laugh.
When asked how they would tease the episode for the fans, the actors were quick to cut to the chase.
"It's a musical episode where Hook and Emma…" Morrison began thoughtfully.
"Get married!" O'Donoghue chimed in with a smirk. "Teased! Boom!"
"Oh wait, you mean without a spoiler? Umm, but it’s a spoiler, on top of a spoiler, wrapped in a spoiler!" Morrison dished. "Hook and Emma find themselves on a brand new adventure that changes the rest of their lives. Wait, that's not good. Hmm, OK. Hook and Emma follow through on a critical decision…"
"With music, and dance, and some mighty fine romance!" O'Donoghue added.
Although we're not going to reveal any specific episode details at this time, we can tell you that Morrison and O'Donoghue are well aware that Captain Swan fans are going to completely lose it when they see Emma and Killian's wedding.
"I hope their brains explode!" Morrison giggled playfully. "I mean, I hope they enjoy it as much as we have. It's been so fun. I just said it again!"
