‘Once Upon A Time’ Season 4 Spoilers: Premiere Title Released Online; Hints At ‘Frozen’ Story

“Once Upon a Time” ended its third season with a major cliffhanger – the arrival of Disney’s “Frozen” Snow Queen, Elsa. The new character and introduction of a different fairy tale drove fans of the ABC drama into a frenzy. And fortunately it appears that viewers won’t have to wait too long to dive into the Storybrook and Enchanted Forest versions of Elsa, Anna and Kristoff.

Series co-creator Adam Horowitz took to Twitter on Monday to release the first major spoiler of the highly anticipated fourth season – the premiere title!

“Here’s our first #OnceUponATime #titlespoiler of Season 4 – hope to see ya this fall!” Horowitz tweeted along with a photo of the script’s front page.

While Horowitz didn’t go into any specifics about the premiere episode, the title, "A Tale of Two Sisters," seems to hint that viewers will immediately find themselves entangled in the “Frozen” storyline when the show picks up in the fall.

For those unfamiliar with Disney’s 2013 hit animated movie, “Frozen” is the tale of two estranged sisters – Elsa and Anna – who must find their way back to each other. Elsa, the next in line for the Arendelle throne, possesses the ability to create snow and ice. But the young woman does not have the power to fully control her magic. After getting into a fight with her younger sister, Anna, Elsa accidentally casts an eternal winter upon Arendelle and flees her beloved kingdom. It becomes up to Anna, with the help of a mountain man named Kristoff, to reunite with her sister and bring her back to the kingdom and end the eternal winter.

Elsa made her first appearance on “Once Upon a Time” in the final moments of the Season 3 finale. An urn, which accidentally traveled with Hook and Emma from the Enchanted Forest of the past, spilled its contents and formed into the Snow Queen.

“You know, there’s a backstory to how she appeared in Rumpel’s vault, and what she’s up to now when she’s walking out of that farmhouse that we’ll get into very quickly, most likely in the premiere, “ Horowitz told Entertainment Weekly after the finale. “And in doing so, we very much want to honor what came in the movie. We’re not trying to redefine the character; what we’re trying to do is take the beloved character and fit her into our world.”

Despite Elsa’s brief appearance in the finale, the character was only cast last week. TV Line broke the news that “Fringe” alum Georgina Haig will be tackling the role of the Snow Queen. Meanwhile, newcomer Elizabeth Lail will be playing Anna, and former “Greek” heartthrob Scott Michael Foster will be portraying Kristoff.

A few hours after releasing the premiere title, Horowitz continued to tease fans by revealing that he just had dinner with Haig and Lail.
