"Elsa, you look beautiful," she said. "And this place is amazing."

Elsa smiled. "Thank you. I never knew what I was capable of."

Anna cautiously entered Elsa's palace. She found herself in a huge room with an impressive winding staircase leading to a second floor. The palace was gorgeous, but it was absolutely still and eerily quiet. "Elsa?" Anna called nervously. "It's me, Anna."

"Anna," Elsa replied. Anna followed the sound of her sister's voice and saw her at the top of the staircase. She was surprised by Elsa's new appearance.

Anna started up the stairs. "I'm sorry about what happened. If I'd known…"

Anna was startled. "But I just got here."

"No, it's okay," said Elsa, backing away. "You don't have to apologize. But you should probably go, please."

"You belong in Arendelle," Elsa explained. "I belong here. Alone. Where I can be who I am without hurting anybody."

"Actually, about that -- " Anna began. But Olaf ran in, interrupting her. The minute was up, and he couldn't wait another second.

"Wait," said Elsa, wide-eyed. "What is that?"

Olaf ran up the staircase. "Hi, I'm Olaf, and I like warm hugs," he said. Suddenly, the little snowman felt shy. "You built me," he told Elsa. "You remember that?"

Elsa stared at him. "And you're alive?" she asked in wonder. She looked at her hands, amazed at her own power.

"I think so," Olaf replied.

"He's just like the one we built as kids," Anna said. "We were so close. We can be like that again."

Elsa turned and headed back upstairs. "No, we can't," she said. "Goodbye, Anna."

More than anything, Elsa wanted that to be true. But the white streak in Anna's hair was a constant reminder of that night long ago when she hit Anna with her dangerous powers.

Anna ran to the upper floor and tried to reason with her sister. Now that Elsa's secret was out, Anna thought they could be happy together for the first time in forever.

But it wasn't that simple for Elsa. She was sure no one in Arendelle would ever accept her again. She couldn't hide her powers anymore -- and she didn't want to! What if she injured someone? What if she hurt Anna? Elsa felt that if she could just keep to herself, no one would be hurt by her magic. But there was something Elsa didn't know.

"Elsa, wait!" Anna said. "Please don't shut me out again."

"Everywhere?" said Elsa, shaken by the news. Anna wanted to be encouraging. "It's okay, you can just unfreeze it."

"You kind of set off an eternal winter everywhere," Anna said.

But Anna kept pressing Elsa. "Everything will be all right," she insisted.

Elsa looked away. "No, I can't. I don't know how," she admitted.

Anna wasn't worried. "Sure, you can. I know you can." Anna ran to her sister. She was sure they could work it out.

Elsa was torn. She did want to go home, she did want everything to be fine, but it just wasn't possible! Frustrated and upset, she exclaimed, "I can't!"

With those words, Elsa's bottled-up emotions rose to the surface. A wave of icy magic was released from her body, and it struck Anna right in the chest! Anna fell backward as Elsa gasped.

For her part, Elsa was having trouble keeping her emotions under control. The news that she had accidentally put Arendelle into a deep freeze was very hard to bear. Maybe she was the monster that people thought she was. The walls of the palace started to ice over. Elsa wanted to get away from Anna. She backed farther up the stairs, and the banister frosted over as she passed.

"I'm okay," she said bravely. "I'm fine."

"No, I'm not giving up," Anna said. "I know we can figure this out together."

Olaf ran to Anna and helped her stand up. Kristoff entered the room and ran to Anna, as well.

"I told you to stay away!" said Elsa in horror.

"I don't know," Anna said, tears welling up in her eyes. "But I'm not leaving without you!"

"How?" Elsa shouted. "What power do you have to stop this winter? To stop me?"

Heartbroken, Elsa looked at her sister. "Yes," she said. "You are." She waved a hand, and magic shimmered in the air. Suddenly, a giant snowman rose from the floor, conjured by her powers. The snowman grew and grew, until he towered over Anna and her friends.

"You made me a little brother!" Olaf exclaimed happily. He turned to the huge creature. "I'm going to name you Marshmallow!"
