By now, “Once Upon A Time” fans are well aware that “Frozen” character Elsa will be making her way to Storybrooke. But the question on everyone’s mind is: Will the Snow Queen be good … or evil?

For those who are unfamiliar with the popular Disney movie, Elsa was the princess of Arendelle. She grew up with the power to create ice, frost and snow, but was unable to fully control her strength. As a child, Elsa accidentally injured her younger sister, Anna, and put a strain on her family’s relationship.

Elsa and Anna’s parents, the king and queen, kept the siblings apart for fear that Elsa would once again injure her sister. And in order to protect Anna, had her memory of Elsa’s powers erased. Their decision ultimately ended up causing problems between the sisters, which erupted after the king and queen died at sea.

When Elsa came of age she took over the kingdom, but fled after a fight with Anna triggered her powers. Her magic accidentally cast an eternal winter upon the kingdom of Arendelle, and it was left up to Anna to bring her sister home and end the storm.

In “Frozen” Anna ended up succeeding in reuniting with her sister and ending the eternal winter. But will the same happen in ABC’s “Once Upon A Time”?

TV Line asked “OUAT” co-creator Adam Horowitz if Elsa will be introduced on the show before she and Anna are “happily reunited,” but Horowitz wasn’t ready to spill such a juicy spoiler just yet.

“Maybe yes, maybe no,” he teased. “It could be after. Once can be in a snit for many reasons.”

“Once Upon A Time” viewers will remember that Elsa appeared in the final moments of the Season 3 finale. When Emma and Hook returned from the Enchanted Forest of the past they accidentally brought a stowaway with them from Rumpel’s dungeons … an urn. In the last few minutes of the episode, the urn spilled and formed “Frozen’s” Snow Queen.

With that said, fans should remember that after the finale Horowitz promised that they’re trying to “honor” the movie.”

“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 the farmhouse that we’ll get into very quickly, most likely in the premiere,” the co-creator told Entertainment Weekly. “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.”

As of mid-July, the ABC show was working on casting Anna for Season 4. TV Line is reporting that Elsa is expected to be featured in nine upcoming episodes, while Anna and Kristoff, a mountain man who befriends Anna, will appear in approximately six.
