Last week's episode of Once Upon a Time Season 3 took a familial turn as it revealed that the Wicked Witch (Rebecca Mader) is actually the older half-sister of Regina (Lana Parrilla).
After the revelation, fans took to social media declaring that it was all an elaborate ruse, according to TV Guide.
"The supposed evidence is Zelena enlisting one of her flying monkeys to steal Regina's blood, which could be used to trick the blood locks used in Regina's castle in the Enchanted Forest and her office in Storybrooke. She'd only have to resort to that if she weren't blood-related," states the report.
However, Parrilla debunks that theory.
"As we move forward, other things are discovered, and we learn that she actually is her half-sister," she told TV Guide. "It's quite jarring for Regina. She feels completely betrayed yet again by her mother. She's not too happy about it."
When asked whether it meant that Regina is actually the Wicked Witch of the East, Parrilla played very coy about the Evil Queen's connection to Oz. "There's an interesting twist that's coming up," she said. "I wouldn't rule out that possibility."
Meanwhile, being back in Storybrooke won't be all fun and games since the Wicked Witch, Zelena, has a wild card up her sleeve. Rumplestiltskin (Robert Carlyle) is alive but is being held as her prisoner. Maybe that's the reason this Rumple is quite different from the one fans would remember.
"He's a bit off," says Parrilla. "There's something not quite right with him."
