Love Will Thaw

Jack had been sitting in the dark for the last ten minutes when the door opened again. "Finally! I thought you people had—Olaf?"

"Jack! Look Heidi it's Jack!"

"Hi Jack! Would you like an eskimo kiss?" Jack sighed. "What are you guys doing here?"

"We came with Anna! Let's go see her Jack! Hans has to have kissed her by now!" Olaf and Heidi grabbed his hands and the walked off down the hall. It was strangely deserted, but Jack didn't need directions. After all, he'd roamed these halls since Elsa had been born.

Olaf opened one of the doors with his nose and they found Anna sitting on the floor, curled up into a ball, her hair as white as Jack's used to be. "Anna!"

"Wh-who are y-you? Wait… J-Jack? Jack F-frost?"

Jack scooped her up and placed her in front of the fireplace. Olaf tried to start a fire and Heidi helped by closing the window.

Anna stirred weakly. "Olaf get away from there!"

Jack pushed Olaf away and lit it himself, before picking up Anna and holding her close. She was as cold as he used to be.
"Wow~! So this is heat. I love it… Oh, but don't touch it!" Olaf grabbed a blanket and Heidi came over too. "So where's Hans? What happened to your kiss?"

Anna looked bitter. "I was wrong about him. It wasn't true love."

"But we ran all the way here!" Jack called Hans all manner of nasty things in his mind and held Anna closer.

"I don't understand… why are you not… c-cold Jack?" He smiled. "An act of true love will thaw a frozen heart. I saved Elsa, when the backstabbing prince came to find you. I guess I'm not a Guardian anymore."

"Nah, your still a Guardian," said Heidi dismissively. "You're still tons of fun and I bet if you tried, you could still use your magic!"

Jack rolled his eyes but Anna suddenly looked alarmed. "You two can't stay here. You'll melt."

"We're not leaving here until we find some other act of true love to save you." They sat in silence for a second. "Do you happen to have any ideas?"

Anna snorted. "I don't even know what love is."

Olaf and Heidi brightened. "That's okay, we do! And so does Jack!"

"What?"

Olaf continued like he hadn't heard the fun-loving Guardian. "Love is putting someone else's needs before yours."

"Yeah," chimed Heidi. "Like, you know, how Kristoff brought you back here to Hans and left you forever!"

Jack gave Heidi a glare. "Why don't you go check the weather, snow girl?" But Anna had taken something else out of that sentence. "Kristoff loves me?"

Jack rolled his eyes. "Really? You couldn't tell?"

Olaf blinked. "Wow you really don't know anything about love, do you?" His nose started to slide down his face.

"Olaf, you're melting."

Olaf smiled and Heidi came back over. "Some people are worth melting for." Then their faces started to droop. "Just maybe not right this second."

The windows burst open and Olaf ran over. "Don't worry, I've got it." Jack fussed with Anna's cloak when he heard Olaf say, "We're gonna get through… Oh wait, hang on, I'm getting something."

Heidi joined him and squealed. "It's Kristoff! And Sven! They're coming back this way!"

Anna looked up "They… they are?"

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

Jack groaned in frustration. "Come on Anna!"

Olaf cried out in alarm. "No, no, no! You need to stay by the fire and keep warm."

She shook her head. "I need to get to Kristoff." He looked at her blankly. "Why?" Both Jack and Anna raised an eyebrow at the snow people and Heidi and Olaf gasped. "Oh! We know why!"

"There's your act of true love Anna," said Jack carrying her to the door.

"Yes!" cried Olaf. "Riding across the fjords like a valiant pungent reindeer king! Come on!"

Suddenly the ceiling and wall started to freeze over.

"We're trapped!" Olaf wailed. Panicking, Jack swung one end of his crook and icy magic blasted from it, clearing a window. They all stared at it and Jack said, "Huh. Guess you right Heidi. Come on guys!"

"Slide Anna!" yelled Olaf and everyone went on a wild ride down the side of the castle. Anna pushed herself away from Jack. "What are you doing?!"

"Go find Elsa! Help her stop this! Hurry!"

"It's okay Jack!" said Heidi as she and Olaf followed Anna. "We'll help her!"

Jack hesitated, but Anna yelled, "Go!" He held up the two ends of his staff and pushed them together. Ice coated the break and without testing to see if it would hold, Jack jumped on his staff and sailed into the air. Somewhere in the back of his mind, he wondered how he was still able to do this. Then he decided he didn't care as long as it helped him save Elsa. He soared above the storm, trying to find his queen, when suddenly it all stopped. Jack could see Anna and Kristoff, close but not close enough, and he could see Elsa and Hans. The young queen had fallen to her knees and was sobbing and Hans had his arm raised, sword in hand. "NO!"

His voice was echoed by Anna's and he watched in horror as the younger sister protected the older by throwing herself under the blade.

It was then that Anna's heart froze completely and turned her to ice. Hans' sword shattered on her hand and he stumbled backward. Jack swooped down and tackled the stunned prince to the ground.

He snarled furiously. "Shepherd—"

CRACK! Jack whacked him over the head with his crook. "I told you, I'm not a shepherd."

"Anna!" Jack turned and saw Elsa stand in front of her sister. For the first time since they were little girls, Elsa threw her arms around her and sobbed. "Anna… Anna, no….no, please no… Anna…"

Kristoff, Sven, Heidi and Olaf came up and Olaf whispered, "Anna?"

Jack lowered his gaze to the ground. "She saved you Elsa."

"She died! No, I can't! She can't! Oh, Anna!" Jack slumped to the ground, his wound throbbing. "She gave her life for yours. The ultimate act of love." He frowned. "Wait a minute."

Olaf gasped and everyone looked up and grinned when they saw Anna thawing before their eyes. "Anna!"

"Oh, Elsa…"

Elsa pulled back from the hug. "Jack was right. You sacrificed yourself for me?"

Anna shrugged and smiled. "I love you."

Heidi sighed happily and Olaf gasped. "An act of true love will thaw a frozen heart!"

Something dawned on Elsa right then and she looked thoughtful. She glanced at Anna. Then she looked up at Jack, with his brown hair and soulful eyes. There was white at his temples now, from using his magic and he grinned back at her. "Love will thaw…" Elsa grinned too. "Love. Of course."

Anna looked startled. "Elsa?"

Elsa lifted her arms. "Love!" Anna gasped as the snow and ice started to melt and gather in a snowflake in the sky. When it was all there and everyone was standing aboard one of the ships, Elsa clapped her hands and made it disappear into a shower of blue sparkles.

The sisters grinned at each other and Anna put her hand on the young queen's shoulder. "I knew you could do it."

"Hands down, this the best day of my life," declared Olaf, his face dripping.

"And quite possibly the last," added Heidi, as her body sagged in the heat.

Everyone laughed and Elsa said, "Hang on you two." She and Jack waved their hands and clouds appeared over the snow people's heads. "Our own personal flurries! Oh we love them!"

They heard a pained groan and saw Hans hauling himself up. Jack and Kristoff glowered. "Why I oughta…"

"Maybe I didn't hit that idiot hard enough."

"Ah, ah, ah, ah!" Anna stopped them and marched up to Hans. He looked shocked. "Anna? But she froze your heart."

"The only frozen heart around here is yours," she sniffed and turned around. Then she socked him in the mouth and sent him flying into the fjord.

Everyone cheered and Jack grinned at Kristoff as the sisters hugged again.

Jack later stood with Elsa in the hall and laughed when she told him what she had done to those who'd tried to dethrone and kill her. And he grinned when she told him what she did to reward those who stuck by her. "The Official Arendelle Ice Master and Deliverer? That's not a thing, Queenie."

"Sure it is. I made it a thing." He laughed again and walked Queen Elsa of Arendelle out to the courtyard where everyone was waiting. Anna ran up to them and Elsa grinned at the crowd. "Are you ready?"

Everyone cheered and Elsa lifted her skirt like she had as a child and stomped on the ground. Ice spread out and everyone started ice skating. Then she raised both arms and froze the fountains into beautiful sculptures and shot of sparkles in the sky. Jack smiled at the sisters as the hugged, Anna slipping a bit on the ice. They hadn't been able to do that for so long, so they were catching up.

"I like the open gates," said Anna shyly. Elsa grinned. "We are never closing them again." She made Anna some ice skate and Jack idly skated around behind her.

"Oh Elsa, they're beautiful but you know I don't skaaAAAAATE!" Elsa had grabbed her hands and Jack had put their backs together and like when they were children pushed them around the ice with his magic. "Come on, you can do it!

"I got it! Ah! I don't got it, I don't got it!"

Olaf and Heidi glided and pivoted around the princess and ferried her toward Kristoff. Jack swung Elsa around and waltzed with her as if they were on a dance floor. "So. Kristoff gets a new sled and an even newer title. Do I get something?"

Elsa smiled mischievously. "Oh I don't know. There is one dusty old title I think I could give my oldest suitor."

Jack made a face. "Oh god, don't say it like that. It makes me sound like a cradle robber." She giggled and he smiled at her. "So what's this title?"

"How does King Jack of Arendelle sound to you?"

"Pretentious," he deadpanned. "How about just Queen's Husband and Champion?"

She threw her arms around him and bussed his nose. "Sounds perfect to me."

He smirked and suddenly dipped her. Elsa laughed and Jack leaned in and kissed her.

And they lived happily ever after.
