The next episode of "Once Upon A Time" will follow the Evil Queen as she grants a wish that will radically change Emma's fate.

In episode 10 titled "Wish You Were Here," Emma will wish that she never became a Savior. The Evil Queen will throw her wish back at her, resulting in Emma's past and future changing drastically.

"When she learns that our heroes possess a weapon capable of defeating her, the Evil Queen steals Aladdin's magic lamp from Jasmine and makes a wish that could sideline the Savior forever. Unwilling to wake Snow while Emma is missing, David works with Hook and Henry to hold the Evil Queen at bay in Storybrooke as Regine goes on a rogue rescue mission.  Meanwhile, Gold and Belle face a surprising danger to their newborn son," reads the synopsis for the episode.

The preview video for episode 10 shows Emma arriving in a diner with David and Hook. There she finds Jasmine bound to a chair, while the Evil Queen and Aladdin stand beside her.

"I wish Emma Swan's wish be granted," orders the Evil Queen.

Emma tries to stop her, but Aladdin makes use of his power to make Emma vanish.

Elsewhere in the episode, Regina finds Emma strolling around the forest, picking flowers and not caring about the world.

Towards the end of the preview, the Evil Queen says, "You can't undo wishes."

Directed by Rob Underwood, "Once Upon A Time" season 6, episode 10 airs on December 4 on ABC.
