Once Upon a Time Spoiler Photos: Season 3, Episode 20 — “Kansas”

The Snowing baby is finally here on Once Upon a Time Season 3, Episode 20 (“Kansas”)! The newly released promo photos of the episode give us a close look at the baby's birth, and we already can't wait for the happy Charming family moment — though we're worried about how Zelena will interfere.

The photos also give us a look at some of Zelena and Glinda's backstory, which should hopefully give us more clues into exactly why Zelena turned out as evil as she did.

Want more info? Here's what the official synopsis has to say:

"With Mary Margaret in labor and due to give birth at any moment, the residents of Storybrooke go on high alert in an attempt to ensure that Zelena doesn’t try to steal her newborn baby for use in her ultimate game plan to turn back time and change her destiny — while obliterating Regina’s existence. Meanwhile, in the land of Oz of the past, Glinda tries to convince Zelena to fight her evil tendencies and join her and her sister witches as a protector of Oz. But the appearance of a young girl from Kansas could turn out to be her undoing."
