“Once Upon a Times” fans may want to break out their winter jackets. Things got a little chilly in the Season 4 premiere of the hit ABC fairytale series when episode 1 introduced “Frozen’s” Anna (Elizabeth Lail) and Elsa (Georgina Haig). But the town of Storybrooke is about to get downright icy in episode 2, “White Out.” As we previously reported, the Sunday, Oct. 5 episode will find the show continuing to use flashbacks to tell the story of Elsa and Anna -- while introducing some familiar characters the girls have run into in the past. But as fans get acquainted with the newcomers, Storybrooke will get a rude awakening when Elsa decides to set an icy trap to find her sister in this strange new world.

Two sneak peek videos from episode 2 give “Once Upon a Time” viewers a small taste of the odd obstacle the Storybrooke residents must now overcome:

Sneak Peek #1

In the first clip from “White Out,” Elsa is bent on finding Anna. The last time she saw her sister was in Arendelle when she left on a mission to find out where their parents were searching for when they left on the voyage that took their lives. The only problem is that Elsa is in a strange new land and has no idea where Anna might be -- which is why she creates a wall of ice to trap everyone in Storybrooke.

“Until we’re together, no one leaves this town,” Elsa says to herself, triggering her magic. “Anna, we will find out what happened to you.”

Sneak Peek #2

A second clip from episode 2 reveals Elsa’s magic not only trapped the Storybrooke residents in town -- but it also cut off their power. While electric didn’t exist in the Enchanted Forest, the fairytale residents have become pretty reliant on it.

The video shows Mary Margaret (Ginnifer Goodwin) trying to work on a generator while Leroy (Lee Arenberg), Happy (Mike Coleman) and Granny (Beverley Elliott) pitch ideas of who could potentially help them get the power working again -- like Marco (Tony Mendola) and Dr. Whale (David Anders). Mary Margaret insists they don’t need anyone’s help, but Grumpy fires back that if he’s grumpy now just imagine what he’d be like in the morning without his coffee maker. When Happy starts going on about other electronics they need, Mary Margaret completely snaps.

“Look, I am not magic,” she yells at them. “I have had eight hours of sleep in the last week, I am breast feeding and I am exhausted. I don’t need this. I may have cast a little curse, but I did not ask to maintain a metropolitan electrical grid.”

Her full break down can be watched below:
