Anna was shivering in Jack's arms. He was trying to keep her warm as much as he could but because of who he was there was nothing he could do.

Then they saw door handle suddenly jiggle. Stopped and then jiggled again.

In barely a whisper Anna said, "Help."

CLICK. The door swung open. They saw a carrot in the lock and heard a giggle of victory. The door opened to reveal Olaf. Olaf took the carrot, and put it back on his face. Then he saw Anna lying in Jack's arms.

"Anna! Oh no!" He ran to the fireplace. Then he threw in some fresh wood, including one of his own arms, which he quickly rescued, before striking a match and relighting the fire.

"Olaf? Olaf. Get away from there." Anna said to him.

"Whoa! So this is heat...I love it." He reached a twig finger toward the flames. It caught on fire. "Ooh! But don't touch it!"

He shook the flame out, as he rushed over to help Anna to the fire. When he went to take Anna from Jack's arms he looked up at Jack. Did he see Jack too?

Jack went to test if he was right. "Um…hey, Olaf."

Olaf smiled. "Hey! I remember you! You're Jack Frost. Elsa would make me all the time while you guys were out playing."

"You never talked before. Now you're alive and talking." Jack said confused.

"Well, unfortunately I can only talk because of Pitch's spell he put on Elsa."

Then he remembered. "Olaf, do you know where Elsa is?"

"No, sorry. I hope she's alright."

"Yeah…me too."

Olaf took Anna over to the fireplace. "So, where's Hans? What happened to your kiss?"

Anna felt ashamed. "I was wrong about him. It wasn't true love."

"Yeah, the jerk was two-faced all along!" Jack added.

"Huh? But we ran all the way here?" Olaf said with confused innocence.

"Please, Olaf, you can't stay here; you'll melt." Anna hated being the one to tell him the truth.

But Olaf didn't mind, nor did he care. "I am not leaving here until we find some other act of true love to save you." He sat down behind her with Jack, stubbornly. Then the leaned his back against hers and thought. "...Do you happen to have any ideas?"

Anna had given up. "I don't even know what love is."

"That's okay, I do. So does Jack." He said confidently. "Don't we Jack?"

Jack thought of Elsa. "Yeah…I guess so."

Olaf hopped back up and put a soothing hand on her shoulder. "Love is...putting someone else's needs before yours, like, you know, how Kristoff brought you back here to Hans and left you forever.

"...Kristoff loves me?" Anna said with surprise.

'So that was the name of the mountain man.' Jack guessed.

"Wow, you really don't know anything about love, do you?" Olaf said, surprised. Then his face started to melt.

Anna and Jack started to notice. "Olaf, you're melting." Anna warned him.

"Yeah! You have to leave the room now, Olaf. I'll stay with Anna." Jack told him.

Sweet and reassuring Olaf said. "Some people are worth melting for." Anna and Jack smiled at the kindness. But then...his face REALLY started to melt. He panicked and pushed the snow back in place. "Just maybe not right this second."

Suddenly, the window blew open and cold wind swept in.

"Don't worry, I've got it!" said Olaf. Jack held Anna to keep her warm, away from the open window. Olaf flittered to the window. He pulled one panel of it shut but struggled with the second. "We're going to get through-" but then he got distracted. "Oh, wait. Hang on. I'm getting something." He broke an icicle off the window, used it as a telescope and saw Kristoff and Sven running back down the mountain. "It's Kristoff and Sven! They're coming back this way."

Anna looked over Jack's shoulder. "...They-they are?"

"Wow, he's really moving fast. Huh... I guess I was wrong. I guess Kristoff doesn't love you enough to leave you behind." Olaf said, actually feeling stupid.

Jack rolled his eyes. Then he felt Anna getting out of his arms. "Whoa, Anna, what are you doing?".

Anna tried to get to her feet. "Help me up, Olaf, Jack. Please."

Olaf hurried over, tumbling over the couch, knocking over the chess set and water jugs. "No, no, no, no, no. You need to stay by the fire and keep warm."

"I need to get to Kristoff." She said to them.

Jack and Olaf looked at each other clueless. "Why...?" they said in unison.

Anna stood there in front of them, waiting for them to get what she was saying.

Then the guys realized. Jack smiled and Olaf smiled even bigger. "Oh, oh, oh, I know why." He hopped around in an excited display of hope. "There's your act of true love, right there, riding across the fjords like a valiant, pungent reindeer king! Come on!"

Then the walls cracked under the ice pressure.

"Look out!" Jack yelled.

They rushed out the room just as the ceiling collapsed. Jack picked up Anna and carried her to make it easier on her. Olaf got up on Jack's shoulder. Jack was about to start flying their way out but he struggled down the hall. Ice spikes grew and blocked their path.

"We're trapped." Olaf said in worry.

Anna, in Jack's arms, looked around desperately for a way out.

Mean while, outside the castle in the fjords, Elsa ran, but was nearly blinded by the snow and wind she had caused. She needed Jack and Anna. She needed them right now more than anything.

(A/N) I love making Jack and Anna have scenes like they're brother and sister.
