By now fans have theorized whether or not Peter Pan is going to unleash the curse on Storybrooke or if he will be stopped.
According to TVLine.com, show creators Adam Horowitz and Edward Kitsis aren't revealing that information. However, according to an interview the two did with the website, they did relay Sunday's midseason finale will "tie up" many "loose ends."
"By the end of Episode 11, most of the loose ends are tied up. Like, 'Does Tink get her wings back?' - all these questions will be answered," Kitsis said. "It will feel very much like a season finale, and we are very much setting up what will be a season premiere in March."
According to Horowitz, Suunday's episode should create a transition from the first half of the season to the second.
"The midseason finale is meant to tie up all of the arcs and loose ends from the first half of this season, while also endeavoring to carry over the story into what we are hoping is a compelling new mode of storytelling in the second half," Horowitz said.
By now, fans who read "Once Upon a Time" spoilers may know Rebecca Mader ("Lost") is on her way to the show to play the new big bad. As EOnline, put it, she'll play the role of an "iconic fairytale villain." Who do you think Mader will be playing? Theorize below.
"Once Upon a Time" airs Sundays at 8/7c on ABC.
