Harry groaned, feeling the castle shake as the air grew colder. The Duke's men looked around in fear, one of them taking a step back and onto the chains holding Harry. Setting his face into a grimace, Harry began to channel electricity through the metal, gritting his teeth as he fet himself get shocked in the process.

"For Elsa" He whispered

With a burst of light, the metal lit up as lightning arced along it and into the soldier in front of Harry. At the same time, the castle shook and a beam came loose from the ceiling, breaking the post attaching the chain to the wall as it did so. With a scream of pain, Harry stood up, bruised, bleeding, and burned. Swinging his arms, he wrapped the chain around the neck of the second man and charged it with lightning again.

After killing the two soldiers, he coated the metal in ice before slamming it against the wall. Feeling the metal loosen, he kept slamming it into the wall until finally the metal gave way with a screech. Removing his hands from the metal, he hissed in pain as several jagged bits of metal scraped across his hands, carving shallow cuts all across his forearms. Exiting the room, he looked out the window

"Oh no…"

Anna and Olaf ran through the halls, avoiding the ice, before reaching an intersection of several halls. As they were about to go down one hall, they saw a dark haired man covered in blood running towards them.

Anna screamed as he got close to them, scrunching her eyes up. After a few seconds, she opened her eyes and saw him twisting the torch on the wall.

"Hey! What're you doing? Who are you?"

The man turned to them, before gesturing to the wall as it slid away.

"I'm saving us, now quickly, into the passage."

Rushing into the passage after the man, Anna marveled at the stonework around them.

"How did you know this was here? I've lived in this castle my whole life and I never even thought there'd be anything like this in here!"

"I'll explain later. For now, we need to go help Elsa!"

Anna gave the man a strange look, wondering how he knew Elsa, before running with him, the passage ending in a door that let them out at the fjord. The man ran into the blizzard, quickly disappearing from sight. Chasing after the man, Anna ran through the snow, Olaf being blown away behind her. Yelling for Christophe and Elsa, she shuffled through the winds, feeling her strength leaving her as the warmth left her frozen body.

Harry wildly ran through the snowy haze, hearing Anna call behind him for her sister and someone who he didn't know. Putting her out of his mind despite her sickly appearance, he kept running, yelling out Elsa's name as he ran.

Narrowly avoiding a crack in the ice, Harry dodged a crate. Looking askance at the crate, he saw a shadow fall over him. Dodging the reindeer that blew by him, He looked up and saw a ship flipping and falling down towards him. Seeing no other alternative, he created a cone of ice above his head and began to cover himself in a layer of ice.

Feeling the impact of the wooden ship, Harry groaned in pain as he felt a shard of wood imbed itself in his arm where his shield was weak, before pushing up. Feeling the wood give way, he climbed up onto the ship. Seeing a hole in the wreck, he ran towards the far end of the boat and dove out of the hole, the bottom of the boat falling down where he had been not seconds prior. Standing up, he heard someone yell.

"You can't run from this!"

"Just… take care of my sister." He heard Elsa reply.

"Your sister? She returned from the mountain weak and cold! She said that you froze her heart! I tried to save her but it was too late…" he heard the man say.

Realizing what effect that would have on Elsa, Harry began to run towards the voices, stumbling through the snow as the blood-loss from his earlier beating and the wood lodged in his arm began to get to him.

"Her skin was ice, her hair turned white…"

Harry limped forwards, intent on getting to Elsa before this man did.

"Your sister is dead… because of you!" he heard the man accuse.

"No! ELSA! He's lying! She's alive!" Harry yelled.

He grimaced as the wind picked up, swallowing his shouts.

Then the snow stopped, frozen in the air as the wind died. As it fell, it revealed Elsa in a heap on the ground, crying. A man stood over her, his countenance full of malice. Seeing his drawn sword, Harry cried out, unable to move due to his injuries. He saw the man swing his sword down, ready to take Elsa's life. Watching helplessly, Harry saw Anna run up and put herself between the man and Elsa. She glowed and turned to ice, the sword shattering in her grip as she became a statue.

"ANNA!" Elsa cried out, standing and holding her hand to her mouth, tears that were already falling only intensifying.

"No… No… Please, no…." She whispered.

Falling against Anna, Elsa began to sob, as Harry began to lose feeling in his extremities. The blonde man and the snowman that had accompanied Anna reached Elsa, looking at the statue of Anna in shock. Looking around, he saw Harry on the ground and ran towards him. Helping him up, he helped Harry stand, and the two of them stood back as Elsa cried, Christophe unsure what to do, and Harry too weak to do anything at all.

Resting Harry against the reindeer, the blonde man approached Elsa softly, looking unsure about if he should be there. As he approached, Anna began to glow, before the ice began to recede, leaving Elsa crying against a very much alive Anna. Looking up at Anna, Elsa smiled, before hugging her.

"Oh Elsa…"

"Anna! You sacrificed yourself for me?"

"I love you"

Harry smiled, leaning against the reindeer and watching as Elsa's world began to come back together from the pieces it had been falling apart into. He missed what the snowman had said, but Elsa turned towards the kingdom, the gleam in her eye she got whenever she had an idea.

"Love will thaw…" She muttered.

-line break-

Elsa smiled as the ice around them began to melt, the ship below them all unthawing and beginning to bob back and forth in the water once again.

Spinning, Elsa began to melt the ice around them, the effect spreading to encompass all of Arendelle. Smiling widely, she dispersed the ice and snow until it vanished, leaving the kingdom green again.

Turning to smile at Anna, she looked past her and smiled at Christophe, before looking past him at the reindeer and the snowman. Olaf wasn't looking as happy as the rest of them. He was drooping, understandably so due to the fact that he was made of snow, and looking worriedly at something behind the reindeer. Elsa walked up to Olaf and waved her hand, fixing him and ensuring he wouldn't melt.

"What has you looking so worried, Olaf?" Elsa asked, kneeling down beside him.

"The man who helped us get out of the palace, Mr. Green Eyes. He looked like he might need some magic, too."

"Mr. Green Eyes…?" Elsa asked, before her eyes widened.

"HARRY!"

-line break-

Harry smiled as he watched Elsa remove the snow and ice, Arendelle returning to the way it was prior to all of this. As he turned and watched her smiling, he went to take a step forwards, but felt his legs go weak. Collapsing softly, he slid himself behind the reindeer, content to let them all celebrate.

'As long as Elsa's happy and free of the stigma her powers had originally brought, then I can be happy with that' was his last thought before unconsciousness claimed him.

-line break-

Anna smiled as she watched Elsa remove the ice and snow from Arendelle, her pride in her sister skyrocketing. Looking around, she saw Elsa fix Olaf, but frowned as Olaf mentioned the man from earlier. Before she could ask Elsa about him, she saw Elsa look around fearfully, before rushing towards someone she guessed must be him slumped against the edge of the boat behind Sven.

"Who is he Elsa?"

Elsa ignored her, crying as she looked over the bloodied man. Looking closer, Anna realized he was covered in bruises, cuts, and burns, as well as having several large pieces of wood stuck in him. Gasping, Anna moved closer, watching as he opened his eyes to reveal the brightest shade of green she had ever seen someone's eye be. Hugging Christophe as he held her, she watched Elsa and him whisper quietly to one another, before Elsa began to pull the wood out of his arm and quickly hold her hands there, her hands glowing blue.

Crying as she did so, Anna let go of Christophe and hugged Elsa, ignoring the fact that she didn't know the man. Her sister was upset about him bring hurt. That was enough for her. The two sisters held one another, Elsa sobbing as the man went still.

-time skip: 1 month later-

"I still can't believe he lived in the palace with us for years and I never even realized he was here."

"He was always better than me at sneaking around. He knew the secret passages of the castle better than anyone. He had to… he was my secret… my Harry…" Elsa said, her voice cracking.

Anna held Elsa, rubbing her back as she cried on her sister's shoulder.

Harry groaned, holding his head as he woke up with his head feeling like the morning after the time he had snuck into the local tavern. Opening his eyes, he saw the ceiling of the room he used to call his bedroom. Back when he lived in Britain….

Harry shot out of the flimsy bed he was in, falling over his own feet as he did so. Looking down at himself, he gasped, his voice a higher pitch than he was used to.

"WHAT?!" Harry whispered, looking down at his younger body.

Looking at his hands, he caught sight of the ring he had gotten from Elsa. When they were ten they had exchanged two matching rings so that if they were ever apart, they would remember one another. Looking around the room, he noticed the box on his bed. Looking inside of it, he saw the sword he had carried shrunken to the size of a toothpick, as well as the wand and two rings, and all of the money he had had with him when he was in Arendelle.

"Did I… did I die?" he asked softly, tears in his eyes.

Tearing through the house after a minor panic attack, Harry began to go through the library, looking for a book on magical transportation.

"I'm coming, Elsa."

Aaaaaaaaaaaaaaaand that's the end of this chapter. I know, us writer's can be sooooo evil. But don't worry, those two haven't seen the last of one another (I don't have a death wish). But it's time to learn how the world of HP will react to an Arendelle-raised Potter.
