Hell hath no fury like a Snow Queen scorned!

For week we've been warning Once Upon a Time fans about the "worst" curse in Storybrooke history, and now we finally know the truth: The Spell of Shattered Sight is not just going to devastate our favorite fairytale relationships, it could kill everyone in town!

The enchanting drama returns this Sunday with an all-new episode and only ETonline has your exclusive sneak peek of The Snow Queen's (Elizabeth Mitchell) evil plan — and a potential ally who is looking to make a deal before the destruction hits.

We're personally keeping our fingers crossed that Rumple (Robert Carlyle) has some kind of trick up his sleeve, and is not fully reverting back to his dark ways. (Think of Belle before you act, Rumple!)

Speaking of reformed villains, we had the pleasure of chatting with the lovely Lana Parilla at the Once Upon a Time set in Vancouver, and she spilled that Regina is determined to do whatever it takes to secure her happy ending in spite of the Snow Queen's wicked ways.

"A villain's fate is always — ugh I don’t want to say the five letter word, but it starts with a "D" and ending with an "H" — and usually that's how it ends," Parilla admitted to reporters. "So Regina wants to fix things before she gets to that place."

Fans know that Regina is currently on a mission with Henry (Jared Gilmore) — code-named Operation Mongoose — so she can find the author of their fairytale book and change her seemingly doomed fate.

"I think that finding the author is a major priority, but it will happen over time," she said. "I'm excited to explore that. Villains deserve their happy endings, and I think that's something we're really going to explore on the back end [of the season].

(By the way, did you know that the brunette beauty desperately wishes that her mission with Henry had been named Operation Honey Badger instead? Parilla confessed with a laugh, "Because honey badgers don’t give a s—t! That what I wanted to say, actually." Consider our day made.)

Meanwhile Regina's love life has been heating up since things with Robin Hood's wife have cooled down. "Regina is torn because there's this love for Robin Hood, and yet she wants to save Marian," she explained. "So she moves forwards in helping him save Marian, which is very unlike Regina. But if she were to do what she would normally do, which is crush that heart, then she would just revert to her old ways. And she's worked way too hard to be that person again."

Not to worry, Outlaw Queen fans! Despite the fact that Marian's well-being is a priority, something incredibly swoon-worthy is going to happen in this week's episode while the couple prepares for the Spell of Shattered Sight to finally hit.

We're not going to spill exactly what is going to be said, but you should definitely scatter some pillows around the room for when you pass out from adorable overload. (But maybe some tissues, too!)

And although Jennifer Morrison described the Spell of Shattered Sight as the "worst," Parilla was quite thrilled to experience such a shocking turn of events. "Oh my god how awesome is that?" she gushed. "We get to become our worst selves and what does that mean? Regina is about to scare the living hell out of everyone, so I'm so excited that's coming up."

Once Upon a Time airs Sunday, Nov. 30 at 8 p.m. on ABC.
