Once Upon a Time stars tease new dangers in Wish Realm

Once Upon a Time‘s trip to the Wish Realm got really complicated in the winter finale — and the danger ratchets when the show returns on Sunday.

During the winter finale, Emma (Jennifer Morrison) found herself in the Wish Realm, a land in which she never became the Savior. In order to wake her from her reverie, Regina (Lana Parrilla) crushed the hearts of Queen Snow (Ginnifer Goodwin) and King David (Josh Dallas), making her the most wanted woman in the land.

Fortunately, Emma woke up. Unfortunately, their escape from the Wish Realm was interrupted by the arrival of Robin (Sean Maguire), who in this world is still very much alive. When the ABC fairy tale drama returns on Sunday, the Outlaw Queen reunion will take a quick turn as the palace guards, led by a vengeful Prince Henry (Jared Gilmore), aim to make the Evil Queen pay.

“We have to find a way out, and we have several people after us because they all think Regina’s really the Evil Queen,” Morrison tells EW. “She’s sought out as being this terrible person, so now Henry is after her trying to kill her. The danger is the entire kingdom is after us, and we’re just trying to figure out how to get back out to stop this weirdness.”

Despite being hunted, Regina may not actually want to leave now that she’s seen Robin again. But this isn’t the Robin that OUAT fans remember — this version is not Robin Hood, but Robin of Locksley. “Regina’s dominated by her emotions most of the time, and seeing Robin really shook her up,” Parrilla says. “She’s in a position where she has to figure out what she’s going to do with that relationship, and even though he’s not real, she has questions and she needs them answered. One of them is, ‘Was Robin better off without her?’ That’s her quest in the winter premiere. There’s still a part of her that is really hopeful.”

But facing off against her son may prove more difficult for Regina. “Killing the Charmings, it wasn’t a real sacrifice for Regina,” Parrilla says. “She was really just trying to wake up Emma, but then when Henry comes forward, it’s a whole different ball game. No matter whether Henry’s real or not, it’s still her son, so she can’t even fathom the thought of hurting him on any level. I think the real danger for them is getting trapped there.”

Once Upon a Time returns Sunday at 8 p.m. ET on ABC. Stay tuned for more OUAT scoop!
