As "Once Upon a Time" season 3 returns with the introduction of Zelena the Wicked Witch, spoilers regarding the cast have surfaced.

First, for those worried about Neal, fans will soon find answers to what he's been up to in Storybrooke in the next few episodes, according to TVLIne.

Spoilers also confirm that there is currently a strong theory circulating that Snow White and Prince Charming's baby is in fact the "Dorothy" counterpart in the Oz story.

The other strong possibility is that Emma is the "Dorothy" of "Once Upon a Time."

“I think so…. Eventually,” says Jennifer Morrison. “I’m not sure, but… a lot of this is about Emma accepting Storybrooke as her home, so I think that’s where the Dorothy theme will come into it, that ‘there’s no place like home.’”

A lot of these connections is also due to the fact that the Wicked Witch (Rebecca Mader) is seemingly "a kindred spirit to Snow White."

“She seems so genuinely kind and has a way of becoming intimate with others and making them trust her," says Ginnifer Goodwin.

"Rebecca Mader called her ‘Mary Poppins,’ because she was just so damn likeable!”

And it is her likability that could get Charming killed, as evidenced by a recent sneak peek from "Once Upon a Time" season 3.

In season 3 episode 14, we see Zelena enter Snow and Charming's Storybrooke home as a potential nanny for the upcoming baby. But things quickly turn sinister when the Wicked Witch attempts to poison Charming's tea!

So why is she in intent of getting near the baby? Could it Dorothy?
