White Out

"White Out" is the 68th episode of Once Upon a Time.

Summary
While desperately trying to find her sister Anna, Elsa is startled by Emma and accidentally traps them both inside an ice cave, with the frozen temperature placing the Savior's life in peril. Regina, depressed over her likely breakup with Robin Hood, secludes herself away from the town and Henry, which saddens her son. And with the townspeople considering Mary Margaret their leader, she faces her first leadership task in trying to re-start a generator and restore the town's electricity after Elsa freezes and damages the power lines. Meanwhile, in the Enchanted Forest of the past, Anna tries to teach a meek David to fight Bo Peep, a brutal warlord who is threatening to take his and his mother's farm away if they don't pay her price.

Plot
"Previously on Once Upon a Time..."

Elsa is seen walking through the streets of Storybrooke, exploring her new location, and leaving an icy trail behind her. Hook tells Emma she's avoiding him; she is seen kissing him and explaining to him that right now she feels too guilty (over having ruined Regina's happiness) and asks him to be patient. Robin Hood tells Regina that his feelings for her are real, but Marian is his wife. Marian is heard calling Regina a monster. Regina then saves Marian's life and Emma tries to talk to her, but the witch disappears. Anna asks Elsa to give her two weeks to travel to Mist Haven. Elsa is worried as she sees her sister setting sail for Mist Haven, and Kristoff informs her that its inhabitants refer to it as the Enchanted Forest. Elsa finds Anna's necklace in Gold's shop.

Teaser
Elsa] is seen inside [[Gold's shop, looking concerned, as she holds up her missing sister's necklace. "Don't worry, Anna," she says, with determination, "I will find you." She is then seen coming out of the store. She looks at the people outside, the cars driving by, the night life, and says, to herself, that until she and Anna are together, no one leaves that town. She clenches her fists, which start to freeze, and then, because of her powers, the town is surrounded by big ice barriers that come shooting from the ground up. "Anna, I will find out what happened to you," the Ice Queen says.

The Enchanted Forest Many Years Ago...

Anna, wearing her red hoodie and cape, walks towards an isolated farmhouse in the woods of Mist Haven, at daytime. She knocks on its door, looking as hopeful as ever, and someone comes to answer it. The person asks if they can help her, to which the cheery young woman replies that she hopes so. "Are you David?" she asks, and we see that the person at the door is none other than a young David, the shepherd. "Yes," he says, "Yes I am."
