Once Upon a Time‘s Storybrooke begins to feel a chill in the air as Elsa arrives in the first promo for season 4.

When the season 3 promotional material for the Wicked Witch left a yellow brick road in her wake, the evil of the looming villain was known. However, when Elsa takes her turn on the streets of Storybrooke, the reaction of the characters shows that no one is quiet sure what to make of the Frozen queen.

‘Once Upon a Time’ season 4 promo:

Storybrooke on Ice, anyone?

Elsa takes her tour through Storybrooke, leaving the residents on edge. It is interesting that the promo chose to have the characters in their Enchanted Forest garb, but set in the modern day town. Rumpelstiltskin lurks in Gold’s shop, Charming and Snow break out their weapons, and Regina works her best high ponytail as the Evil Queen. After a year of torture, fighting both demons of the past and the present, the town cannot catch a moment to breathe.

The feeling is echoed perfectly in the brief exchange as Regina says, “Here we go again,” and Emma replies, “Really?”

We’re looking forward to finally learning the secrets behind Elsa’s presence in Storybrooke, as well as the reasoning behind her imprisonment in Rumpelstiltskin’s vault. The details of Elizabeth Mitchell’s role on the show are still under wraps, but she is rumored to be the original Snow Queen. Anna and Elsa will also be dealing with the return of Prince Hans in Arendelle.
