A/N: Well, expect this to be long. Enjoy! It was only around 3,600 plus words, but I'm proud of it. Additionally, flashbacks are mostly conjecture, the only memory from the movie is the scene where Jack does die *spoilers* in the movie as a human. However, I hope you all enjoy! I really am going to have fun with backstory for Jack!

"Wake up! Jack! Wake up! Please!" Jack blearily opened his brown eyes, not having realized he'd dozed into the snow near the small lake that he and his sister often went to. His sister, shivered next to him, her eyes brimming with tears. "Meanie! You were pulling a prank on me again!" She sniffled. Jack blinked.

"What? No, I was ...I must've fallen asleep..." Jack reached to hug his sister but she moved away from him, holding her skates. She sniffled again. Jack bit his lower lip. He couldn't remember why he'd fallen asleep in the snow. It was cold though. He shifted to his feet, realizing he wasn't wearing shoes. He often went barefoot to show what a tough guy he was, although he figured he should have shoes this time around. His feet felt cold. "It's alright, I'm not playing around, see?" He sounded guilty. His sister's accusing gaze softened.

"...Brother...let's go skate!" She held out her skates. Jack smiled, and ruffled her hair. His little sister giggled. He helped her tie on her skates. He straightened up, and walked towards the ice. However, his sister didn't follow him. He paused and stepping onto the ice, he turned back.

"You coming?" He asked, extending a hand helpfully. His sister shook her head. She looked at him sadly.

"It's not my time," she said, and turned away. Jack blinked in confusion. Not her time? What did that mean? He took a step off the ice but he heard the cracking. He looked down in horror. The ice was cut around him, and cracking still, from his weight. He yelled and tried to jump but his feet were glued to the ice. Looking around, he looked towards his little sister who stood on the bank, and she looked horrified.

"W-what is going on?!" Jack spluttered.

"Jack! Jack! Your hair...it's...it's..." His sister's eyes widened. Jack looked into the ice and saw his reflection; his brown hair was fast turning silver. He looked around, spotting his staff, but it was too far away. He stepped towards it instinctively, not really understanding why. The floor felt like it suddenly moved, and it had. It collapsed under his weight, and all he heard was his sister crying, "Jack! Jack!" as he plummeted into icy cold water. It was so cold. He felt like he was suffocating. He was sweating from the unbearable-

Heat?

Jack's eyes blearily opened, as though dazed as he shifted under soft blankets. Where was he? Who was...Jack's eyes widened. Jack Frost. He was Jack Frost. Not Big Brother Jack. He hadn't been for over 327 years. He sat up too quickly and held his head, feeling a headache coming on. "A dream..." his voice was raspy, shaky, and parched. He took in his surroundings for the first time. He was in a small hut. There was a fire crackling near him, and the smell of stew boiling over a small fire to his left. A window was behind him and he looked over his shoulder, despite the dim light of the candles inside, to see snow covering the land in a peaceful winter wonderland way. He sneezed. It'd been a while since he'd really felt heat. It was...strange. He looked at his hands that had color to them. He was not pale anymore. He felt his face. It felt warm. His heart did loop-de-loops. A nightmare...He had a nightmare. He reached into his jacket pocket and was relieved to find his teeth case still there. Apparently whoever lived here wasn't a thief- as far as he knew. He found this small living home to be spacious. Rudolph though was no where to be found and Jack looked at his feet, realizing that the shoes had been taken off. His jaw dropped. If the shoes were off...then...perhaps? He scrambled out of bed too fast, and forgetting that being bedridden can cause one to lose feeling in their limbs, ended up face-planting loudly on the ground with a disorientated oomph!

He heard the door open just then and in walked a strange looking creature that resembled a large rock, big prominent brown brows, and a shaman like green cape complete with a staff, and a necklace of stones. Jack blinked again. The green cape actually appeared to be long grass? Jack didn't know what to make of this walking rock, with a big nose and deep eyes that looked at him with a smile. "Ah, I see our guest has awoken." He ambled in. Jack urged feeling to come back to his legs. He didn't like being someone quick to trust a stranger, however he wasn't ungrateful for having been rescued. His staff however, was missing, again. Drat. Jack knew he'd have to find it, but the mountains looked the same, so how would he know where to look for it? He'd have to ask whoever rescued him to take him back to wherever it was he'd fallen.

"Who...who are you?" Jack asked, struggling to his feet after some effort, and the creature ambled over, with a small chuckle, assisting Jack back onto the bed.

"Take it easy there, child, you are fit as a fiddle, my my, but don't overdo it, you'll pull something," the creature replied good-naturedly. Jack was good at reading people, but this troll really gave off a family-orientated vibe. He frowned though.

"Who...are you?" Jack repeated.

The creature looked at him with a twinkle in his eye. "Ah, my dear boy, I think the real question is, who are you."

Jack blinked. "I know who I am."

"Do you now? Who are you?" Jack was annoyed at the amusement in the other creature's tone.

"Tell me first, I asked," Jack retorted, childishly.

"Very well," the creature said amused, "My name is Pabbie, and I am the elder troll of The Valley Of The Living Rock..."

"Troll?" Jack repeated in disbelief. This rock looking creature looked no where near intimidating or like anything Jack had ever read. It looked...almost...huggable. Trolls were not supposed to be huggable. They were supposed to be wicked and cool looking...and somewhat dimwitted. At least, that was how Jack had always viewed them and had read. Jack may be Jack Frost, but even he had curiosity and enjoyed reading. After all, weather reports were the most fun for Jack. He loved mixing up the weather reports and having the humans think it was freak weather or global warming. He was a guardian sure, but it didn't mean he had to be perfectly well-behaved all the time.

"Yes, Troll," Pabbie said, scooping out some stew into a bowl for Jack. Jack's stomach growled. Food. He stared at it as Pabbie offered the bowl to him. Jack reached out for it, out of...habit? He felt the warmth pass from the bowl to the palms of his hands, and his brown eyes widened in bewilderment. He could really feel it. Heat. He could smell the food...and his stomach reacted...his mouth watered. Jack eagerly scooped a bite into his mouth, but yelped. His tongue got burned and his eyes watered. Pabbie chuckled and handed Jack a glass of water which Jack quickly swigged. "...not so easy being human again, is it?"

Jack froze, and choked on the drink. Sputtering his eyes widened at the troll. "H-how did...I- I ..." he didn't know what to say. Was he human? Or...was he still Jack Frost under cover? Jack didn't actually know.

"My people...and I...live with nature...we speak to the stones in the mountain," Pabbie said, smiling at Jack. For the first time, Jack noticed that Pabbie's eyebrows were getting more white. He was an old troll, was all Jack could detect.

"...So the rocks told you I was...coming?" Jack repeated.

"...Not just any rock," Pabbie gazed at Jack with a sense of awe, "Sister Moon herself."

Jack did a double take. "Whoa, hold on just a minute," he set the soup down on the table near the bed and glared at the troll. " The moon has a guy living in it!"

"I see...that is how you view the moon," Pabbie nodded, "however, here...she is...Sister Moon."

"She? The moon is girl?" Jack just couldn't wrap his mind around it. I mean, ok perhaps it was as white as like an egg or something but that...Jack made a face at the comforter. "...You know who I am either way, don't you."

Pabbie gazed at Jack and Jack's heart sank as Pabbie nodded. "I know who you are, Jack Frost."

"Do you know the other guardians... do you know Santa Clause?" Jack asked, eagerly.

Pabbie shook his head. "Unfortunately, you have been placed in a different...time and place from what you are familiar to..."

"I know..you have candle-light, and..." Jack's voice trailed off. Candlelight...He remembered how when he'd been human, he'd also had that.

He lived in a simple home...much like this one... in a simple wooden bed, the smell of burning wood crackling to the chirpping of the crickets outside as the pale moonlight would shining through his window. He remembered his mother's face. Her voice telling him a bedtime story.

"Now be a good boy, or Jack Frost will nip your nose..." she would tease him when he was little. He would sit in his bed as she pinched his nose, as he squealed with delight.

"Ma, who's Jack Frost?" He'd ask eagerly.

"A naughty mischief maker," his mother teased.

"I want to be like Jack Frost...he sounds..." Jack couldn't find the words. His mother laughed, letting down her braided bun, and Jack always loved gazing at his mother as she was bathed by candle-light. Her wrinkle lines near her eyes shown, but her dark brown eyes held a twinkle of absolute mischief. She moved gingerly, as her belly was getting a bit big. Jack hugged her.

"Jack Frost..." his mother chuckled, " ... he's quite the character..."

"I like him...he sounds like he likes to have fun!" Jack giggled.

His mother booped his nose. "There may be no bedtime for him, but there certainly is one for you, young man," and Jack gleefully wriggled into his covers, as his mother tucked him in. " You're a good boy, Jack..." his mother kissed his forehead. "I love you very much..."

Warm candlelight. The gentle caress of a mother's loving touch on his cheek. A gentle brush of lips to the forehead. His childhood. His past. Whether it was because of the teeth or his own memory finally coming back on its own, Jack knew that he had been reborn to fill this role...a role he felt was meant for him.

"...Then you know why I'm here..." Jack looked away. His eyes widened. "You..." he looked back at the elder troll. "...Did you and the moon send me here?"

Pabbie looked at Jack a bit guilty. "I was surprised...For Sister Moon tends to...stay quiet...however...she spoke to me...in a dream...and revealed that a boy would arrive in this kingdom...from far away...and would be the one to melt Queen Elsa's heart..."

Jack shook his head. "Don't get the wrong idea! I won't do anything until I can talk to the moon, or the man...or whatever is up in the moon messing with me!" Jack had a renewed energy from annoyance as he swung out of bed. Pabbie blinked at him, and reached into his grass cape, pulling out a small leather pouch that clinked. Jack blinked in surprise. Pabbie held it out to him.

"You are a good lad," Pabbie said kindly, "I know your heart is confused. However, a little love can go a long way."

"Love...how can this be love?" Jack blankly stared at the leather pouch. "... In order to stay a guardian...I have to whoo some woman I never even met..." Jack sounded bitter. Pabbie however chuckled, much to Jack's annoyance.

"Ah, youth..." Pabbie's eyes twinkled. "Love starts with meeting a stranger...the courage it takes to talk to that stranger...is how we familiarize ourselves with those we learn to care about and care for...there are many kinds of love, Jack..."

"...Can you just take me back to my staff?" Jack asked wearily. Pabbie furrowed his brow suddenly, looking away. Jack blinked. "Pabbie?"

"...Your staff I'm afraid...is..." Pabbie beckoned behind him. Against the wall, Jack's eyes travelled to three pieces of wood, all splintered. His eyes widened in horror. Tumbling out of bed, Jack's heart pounded furiously in his ears. No, no, no, no! His staff couldn't be! It just couldn't! He stumbled over to the wall, past Pabbie, who watched him sadly, and helplessly, as Jack fell to his knees, holding in his hands the remains of his staff. The staff that had been his constant companion for so many years. The staff that had saved his sister's life...and began the start of Jack Frost's own. Jack suddenly felt like crying. He normally didn't feel like this. He was a man after all! He'd gotten over tears...right...They silently rolled down his cheeks though, as he felt his heart break in small pieces. This staff had been his hope, and his support. He sank to his knees, desperately trying to fit the splintered ends together but the staff remained lifeless in his warm hands. Jack stifled a sob. What the hell was he supposed to do now. The panic was his initial reaction.

But now it was replaced.

Fury.

Jack straightened up, and looked to Pabbie, his expression dead serious. "Pabbie, take me to your Sister Moon."

Pabbie rubbed his hands together. "I'm afraid I can't do that, lad..." he began but Jack threw the broken pieces of his staff, his memories, and his past, onto the ground with a loud clatter that made Pabbie cringe. Even though Jack could no longer control ice, the feeling and the tension was enough to make the room feel as though it dropped below zero. Jack however, seemed to regret throwing the staff pieces to the ground as soon as he did this though, and it showed clearly on his face as he rushed to pick up the pieces again.

"What do I do...if the moon won't even talk to me..." Jack's voice cracked. He hugged the pieces of the broken staff to his chest, on his knees, and burying his face into his arms. Pabbie placed his hand on Jack's shoulder. Jack didn't have the energy to shake Pabbie off. His instantaneous fury had left as quickly as it had come.

"...I think...the shoes are your link to the moon..." Pabbie said gently. Jack lifted his face, the tears rolling down his cheeks effortlessly though he made no sound, his mouth in a thin line. Pabbie continued, evidently wanting to help Jack's distress, "...Sister Moon...told me that...in order for you to...ah...reclaim your right as Frost, you have to first...thaw out your own heart..."

Jack looked at Pabbie's face, the confusion and pain evident. "Thaw...out my heart?"

"... I ...am from a family of Love Experts..." Pabbie said, with a small smile. "If anyone knows about frozen hearts...it's us."

"My heart isn't frozen," Jack's voice wavered.

" ...No...but...it's never truly been touched either...has it?" Pabbie replied gently. Jack wiped at his eyes with his sleeve, holding the pieces of the staff preciously against his chest with his other arm. "...My dear lad, I'm so sorry about your staff...about...you being human...but it is a trial of the moon...ah...I do believe that your red-nosed friend, Rudolph, is out right now trying to find a way to fix your staff..."

Jack sniffled, having realized he had a runny nose. Pabbie handed him a blue handkerchief with a snowflake sewn beautifully in the center of it, and Jack blew his nose into it. "Fix...my staff...why would he care?"

"I believe he feels guilty...as he was the one who fell on it during that tremendous fall you two experienced," Pabbie said apologetically.

Jack blinked. He could imagine it, Rudolph freaking out, and having a panic attack. Jack looked to the remains of his staff. Though it was precious to him, his staff had yet...led him to another friend. Someone who needed something ...and someone else to believe in them. Jack looked to Pabbie. "...I'm sure he didn't mean it..." and Jack, though he felt upset, knew it wasn't Rudolph's intention at all to have broken his staff. After all, Rudolph had been the one to find it...and there was no way that they'd have outrun the wolves if it hadn't been for Rudolph...and they wouldn't have even been able to see without Rudolph's nose. Jack realized, that his dependence on the staff, came from his lack of being able to depend on others. He thought to the shoes, and to being human again. Who was Queen Elsa? Why had the moon picked her? He turned to Pabbie. "Pabbie, who is Queen Elsa?"

"A lovely young woman," Pabbie said evenly, "who you will meet...after you've recovered...both physically...as well as emotionally..."

Jack furrowed his brow, wiping away his remaining tears. "...I feel fine. Where's Rudolph?"

Pabbie shuffled to the door, and Jack saw him hold out his blue shoes, -without the bells- and look to him. "...your friend is out right now with our dear Anna," Pabbie said with a smile.

"Anna? Who's that?" Jack asked. He put on his shoes, and looked up to see Pabbie hold out a warm fur cape.

"Anna is a fine young woman who would be very pleased to meet you," Pabbie said with a smile. "She already wants to keep Rudolph as a pet though she understands his pride in being free and wild. It seems Rudolph never had the chance to feel accepted by humans...but then he met you..and his confidence grew..."

"It grew? That seems kind of quick for a few...hours..." Jack replied, taken aback. Pabbie blinked.

"...You don't...you don't know?" Pabbie pressed.

"Know? Know what?" Jack asked confused.

"...You've been...you've been out for...2 weeks..." Pabbie said solemnly. Jack's face fell. However Pabbie thumped him on the back. "Just pulling your leg, boy...it's been more like a week... in which time, your friend who had been hiding, met Anna and she took him back with her to the palace so that he could meet Queen Elsa...he seemed very adamant about meeting her," Pabbie chuckled.

Jack's jaw dropped. "I- I was out for that long...who...who fed me..." He looked at his changed clothes, even the pants had been replaced with a pair of dark ivory green leggings. He hadn't been paying attention. His blue jacket had been the only thing that apparently had been put back on him. The rest of the clothes were definitely new. "...who changed me?!" Jack looked to the brown soft bear pelt with bewilderment that Pabbie ambled over with as Jack was inspecting himself. "...Why are you giving this to me?"

"You were underdressed, my dear boy," Pabbie smiled at him, "You should never go out without enough layers, especially since it's January!" Jack didn't disagree and he was grateful for the warmth. His shoes he noticed, however, had changed. His eyes widened. They glowed blue when he put them on after the cape, and he realized they had turned to snow boots, accustomed for the whether. Pabbie chuckled at Jack's bewilderment. "Sister Moon agrees with me..."

Jack watched as Pabbie held out the bowl of soup once more to Jack. "I'm not hungry," he held up his hands.

"...Eat, you won't get any farther than the door in your current state, after all, I know that you are a welcome guest to Arendelle," Pabbie waved off his protest airily. Jack sat on the bed, his growling stomach in apparent agreement with the funny looking old troll.

"Does...Does anyone else know...about...you know..." Jack pressed, feeling a bit uncomfortable.

"No...that I believe is entirely your place to pick time..." Pabbie bowed his head respectfully.

Jack furrowed his brow, looking into his soup, still a bit shaky but growing more determined. He had to get to Arendelle. He had to...he had to do something or else he'd be stuck human... He ate quickly, the soup having cooled. Pabbie watched as Jack took off with the directions to Arendelle. Pabbie turned his gaze to the moon. He closed his eyes. "My old friend...Sister Moon...watch over him as I have..." Pabbie ambled away, back into the small hut, and the door shut with a final small click.
