The howling winds pushed against Kristin as she headed back up the mountain, away from Arendelle. She adjusted her goggles and wrapped her scarf tightly around her face. Svea was lagging behind. The reindeer looked longingly back at Arendelle and the castle. She shook her head and whinnied. Kristin kept walking, ignoring her. Svea charged ahead, passed Kristin, and then stopped in front of her. She faced her and looked Kristin directly in the eye. "What is it, buddy?" Kristin asked.

The reindeer nudged her tiny antlers into Kristin's side.

"Hey, watch it," Kristin said, annoyed. "What's wrong with you?" Svea shook her head and wiggled her mouth.

"I don't understand you when you talk that way," Kristin told her. In a flash, Svea bucked Kristin and lifted her up with his antlers.

"Hey! Stop it!" Kristin shouted. "Put me down."

Svea dropped her straight into the snow, hard.

"No, Svea," Kristin said. "We're not going back." Svea snorted her disapproval.

"He's with his true love." Kristin saw Svea's doubt.

She glanced back at the kingdom to make her point. But to her surprise, she saw a strange new storm swirling above the castle. She could see dark clouds forming, and more ice on the castle walls, putting it into an even deeper freeze.

"Andrew!" she cried.

Instantly, Kristin changed her course and took off running toward Arendelle. Svea scrambled and raced up behind her. She ducked her head and lifted Kristin with her antlers, then threw her onto her back. The duo raced down the hillside.

Andrew was curled up on the floor of the library. He had made it to the door but was now too weak to stand. No one could hear his whispered cries for help. He was so cold—and his heart ached. At that moment, the door handle jiggled. Andrew was barely able to raise his head to see who it was. The lock clicked. Andrew could see a carrot wedged into the keyhole...

Suddenly, the door flew open. It was Olga! The snow woman pulled her carrot nose out of the lock and put it back into the middle of her face. She was very proud of herself, but her happiness melted the moment she saw Andrew. "Andrew, no!" she called. She ran to the fireplace and struck a match. In seconds there was a large, roaring fire.

"Olga," Andrew said.

"Get away from there!"

"Whoa!" Olga exclaimed, taking in the sight and feel of the fire. She was a little scared, but she couldn't resist the warmth coming from the fireplace.

"So that's heat," she said. "I gotta say, I still like it!" She hurried over to Andrew and brought him closer to the fire.

"So, where's Hannah? What happened to your kiss?"

"I was wrong about her," Andrew said. "It wasn't true love."

Olga didn't want to believe it. "But we rode all the way here," she said.

"Please, Olga," Andrew managed to say. "You can't stay here. You'll melt."

"I'm not leaving until we find some other act of true love to save you," Olga said. She sat down next to Andrew.

"Got any ideas?" Andrew sighed heavily.

"I don't even know what love is anymore."

"That's okay," Olga said. "I do." She sat up a little taller. "Love is putting someone else's needs before yours—like, you know how Kristin brought you back here to Hannah and left you forever?"

"Kristin loves me?" Andrew asked. His eyes widened. Olga nodded.

"You really don't know anything about love, do you?" Andrew looked at Olga. She was dripping from head to toe! "Olga, you're melting!" he cried.

"Some people are worth melting for," she said.

Her face was quickly losing its shape. Olga tried to push up her sagging head. She ran and sat behind Andrew, trying to escape the fire's heat.

"Just maybe not right this second." A window across the room blew open and a cold gust of wind swept through. Andrew shuddered. Olga ran to the window to shut it. "Don't worry," she said. "I've got it. We're gonna get through..." She stopped talking and stared out the window. She leaned forward and squinted at the horizon. "Hang on, just one second. I'm getting something!"

She reached through the open window and grabbed an icicle off the window ledge. She flipped the icicle around and used it as a telescope.

"Hey, Kristin and Svea!" she shouted when she realized who was running toward the castle. He turned to Andrew excitedly. "They're coming back this way!"

"They are?" Andrew asked. He tried to stand up to see for himself.

"Wow, she's moving really fast!" Olga said. "Huh, I guess I was wrong. I guess Kristin doesn't love you enough to leave you behind."

"Help me up," Andrew said, struggling. "Please."

"No," Olga told him. "You need to stay by the fire and keep warm" Andrew was adamant. "I need to get to Kristin."

"Why?" Olga asked. Then she paused. "Oh, I know why! There's your act of true love right there, riding across the fjords like a valiant, pungent reindeer queen!"

She reached for Andrew. "Come on!" Sheets of ice began to break through the library walls. The cracks grew across the walls, and the room began to collapse. Andrew and Olga hurried out of the library just in time. Together, they struggled to make it through the hallway, dodging ice as it appeared in their path.

"Back this way," Olga said, pulling Andrew. But every path they tried was blocked by ice! "We're trapped!" she shouted. Andrew spun around and spotted a way out. He took Olga's hand and they made their way over to a window, broke the glass, and slid down an icy ramp. Olga picked up more snow as she went. They landed safely outside the castle and took off toward Kristin.

"Kristin!" he called out weakly. He couldn't see her, but he knew she was coming over the fjord —and he knew she was his last chance for survival.

"Come on! Come on!" Kristin urged Svea.

"Eli!" she yelled loudly through the howling winds. "You can't run from this!"

"I tried to save him," Hannah lied. "But it was too late. His skin was ice. His hair turned white. Your brother is dead because of you."
