Prologue: 2001

"Elsa? Psst, Elsa!" a small voice whispered. Young Elsa stirred in her bed. It was her sister, up again in the middle of the night. Not because she was scared. No, Anna didn't seem to be afraid of anything. But because the sky was awake. Elsa turned in her bed, trying to ignore her 5 year old sister and get some sleep. That plan fell to pieces as she felt her tiny sister crawl onto her bed.

"Wake up, Elsa wake up!" Anna whispered to her sister, who was 3 years older. Elsa turned over again.

"Anna," she mumbled, "What are you doing? It's late. Go on back to sleep."

Anna then preceded to give her "dramatic" performance in order to get her sister's attention. She swooned dramatically on the opposite side of the bed, throwing an exasperated hand to her forehead.

"But the sky's awake, so I'm awake!" Anna gasped with dramatic flair. Elsa couldn't help but giggle as she gave her red-headed sister a playful shove.

"You go ahead and play then!" Anna crawled up to where Elsa lay and brushed her long, white-blond hair out of her face, revealing her matching blue eyes, though, a much deeper shade of blue than Anna's.

"Do you wanna build a snowmaaaan? O.K, that did it. Elsa smiled and crawled out of bed, stopping to put on a pair of winter boots, which matched the pair Anna already had on her feet, like she knew Elsa would eventually cave in. Little sisters...

"Come on, come on! It's snowing!" Anna said gleefully as her and Elsa quietly tried to sneak down the large staircase in their large estate and get past her parents, who were in their bedroom. Anna flung open the door and ran out, giggling and dancing in the snow.

"Anna! Your jacket!" Elsa hissed, bringing her little sister her winter coat and shrugging her's on.

"Oops! Sorry!" Anna replied, taking the jacket and buttoning the snaps. Elsa ran over to a big pile of snow that lay on the ground.

"Come on! Let's build that snowman!" Elsa called over to her sister, who eagerly ran over to help her. A few minutes later, they had built quite a cute little snowman that they both admired for the next few minutes. While Elsa was preoccupied at admiring her snowman, Anna made a tiny snowball and chucked it at her sister.

"Oof!" Elsa said, while trying to keep her balance. She cut her eyes at her giggling sister and smiled as she made another snowball and threw it.

"No!" Anna laughed, running away from Elsa's snowball. "I bet you can't get me!" Anna teased, sticking her tongue out at her sister.

"Oh, you want to bet?" Elsa scoffed, chucking another snowball at her sister, who took off running, laughing the whole way. Elsa continued to throw the snowballs at her laughing sister as the unconsciously got closer to the lake. Anna managed to run out to the lake, Elsa followed, slipping on the slick ice and falling on her side. She gasped when she realized where they were. She looked to her sister, who was still frolicking on the ice, playfully taunting her.

"Anna! Get away from there!" Elsa yelled to her sister. Anna stopped and gasped as she realized she was out in the middle of the lake. She then began to run back to her sister. Elsa looked at the ice and spotted a crack where her baby sister was about to run.

"Anna, no! Go slow! Slow down!" she screamed in vain as her sister neared the crack. As Anna's foot hit the crack, it sent out multiple cracks all over the icy surface, splitting the ice. Anna began to panic as she tried to make it to her sister. Elsa started out after her, but it was too late. Anna took a step and ice broke, tripping her. As she fell, the ice broke and she fell into the icy water.
