As reported by TV Guide, "Once Upon a Time" is going to see the Evil Queen (Lana Parrilla) cause trouble for the heroes once again now that she has separated from her good half, Regina. However, contrary to popular belief the Evil Queen will not be after Regina in season 6 but will revive an old feud with Snow White (Ginnifer Goodwin).

This will complicate things as the season will also see an influx of characters coming in from the Land of Untold Stories into Storybrooke. Jafar (Oded Fehr) is also coming in to cause trouble for Aladdin (Deniz Akdeniz), Jasmine (Karen David), and the rest of the heroes so the Evil Queen's actions will become even more damaging than before.

Movie News Guide further points out that Snow White may not even be able to take the Evil Queen down because she had been spending a lot of her time and effort in previous seasons trying to fix her relationship with Regina. The arrival of the Evil Queen will complicate Snow White's effort.

It is also hinted that the only way for Snow White to take down the Evil Queen is to kill Regina as well. Snow White may not be able to do this due to how she had grown close to Regina and fans speculate Snow White might be killed in season 6.

TVLine does report that Emma (Jennifer Morrison) may be able to save Snow White. Series co-creator Eddy Kitsis reveals that in season 6 fans will see Emma back as the Savior and she may be the one to help Snow White fight back and defeat the Evil Queen once and for all.

"Whereas the Dark Curse gave you no choice, these people chose to pause their lives, for different reasons," explained Kitsis. "We see Emma really back in the position where she's a Savior trying to help people find their happiness."

"Once Upon a Time" season 6 premieres Sept. 25.
