Once Apart Now Together

Snow, soft innocent small yet powerful flakes softly and gently fell from the white sky above him, the world around him seemed to be blanketed in a sheet of white. With a small smile on his face five year old Harry Potter stepped out of his relatives home and out into the white world filled with so much danger yet also filled with so much fun and excitement. As his first foot came down off of the step and down into the snow covered drive way a silly grin appeared on his face as Harry's old worn trainer filled with snow causing some of the pain from Dudley's earlier treatment to become numb thanks to the cold.

As his warm breath turned into smoky mist as it came out of his mouth and a cold wind blew through the empty street of Privet Drive Harry's pale uncovered hands came to wrap around the worn straps that threatened to fall apart of his backpack that held all of his worldly possessions in it and took a deep breath. Then suddenly without a second thought or a single glance behind him Harry lifted his other foot and placed it down on the ground next to his over foot and began walking down the snow covered drive way and out onto the street.

Childish glee entered Harry's mind as he pictured the angry looks on his relatives faces the next morning when they found that he was nowhere to be found inside or outside of the house and they would have to do things for themselves, including making the meals and shovelling the snow off of the drive so Uncle Vernon could get to work. Any fear that Harry might of felt about his great escape plan was blown away as his new big brother stood waiting for him only a few feet away with his trade mark grin playing on his face..

Short spiky white hair, skin as pale as ice and snow, bright playful blue eyes that shone brightly with love, trust, kindness, protection and fun, a thin short body covered by brown deer hide trousers with thin lace from ice skates wrapped around each one of his legs and a soft looking dark blue hoodie with ice covering it as well as the trousers, bare pale feet rested on the ground calmly waiting for someone.

"JACK!" Harry cried out with childish glee as he ran forwards towards his the older boy with excited eyes, "You came! You really truly came for me!"

With a soft smile on his face Jack Frost knelt down and opened his arms for the child as his ice blue seemed to almost melt at the sight of his honorary little brother. A soft smile that could get Tooth and all of her fairies fainting as one came to Jack's face as Harry jumped into his arms with a happy cry.

"I came snowflake, I promised you I would," Jack said softly as he ran a loving hand through the child's hair, "I always keep my word snowflake, I love my little brother too much to leave him here."

As the two continued to hug neither of them noticed the bright powerful beams of light shinning down upon them from the moon until it was too late. As Jack and Harry separated a sharp gasp came to Jacks mouth as he laid eyes on who he knew was his little brother, his Harry, only to find a completely different child standing in front of him.

Gone was the wild black hair that Harry had sported and in its place was wild snow white hair just like Jack's, pale skin from being shoved in a cupboard became even more paler until it was as pale as Jack's, soft pink lips turned to a pale pink almost white colour while Harry's bright emerald green eyes only got brighter. As Jack rested his hands on Harry's small shoulder's the comforting warmth he normally felt coming off of his little brother was gone and in its place was a strange yet comforting and familiar coldness.

"What is wrong big brother?" Harry asked innocently as he tilted his head to the side not realising the change he had gone under, "Is something wrong?"

"No..nothing is wrong," Jack replied with a watery chuckle as he pulled the confused five year old child into a tight loving hug, "Nothing is wrong at all, The Man In The Moon has just officially made us brothers is all."

"Brothers? Really? Harry squealed in excitement as he bounced up and down in his big brother's arms, "We really are brothers now? Does that mean I get to stay with you forever and ever?!"

"Sure does Snowflake," Jake replied with a playful grin at his brother's actions, "It seems that you even have a new look to go too."

"Really?" Harry asked as his eyes lit up with magic dancing in them, "I want to see! I want to see!"

A pure happy laugh came out of Jack's lips as he grinned down at his little brother. Looking around him Jack spotted a frozen puddle of water close by and without a second thought he began to lead Harry towards the ice that would be used as a mirror. As they walked towards the ice turned mirror Jack could not help but to look up at the night sky and send a large happy smile at the full moon.

"Thank you, thank you so much," Jack whispered softly up to the moon with true emotion shining in his eyes, "Thank you so much for giving me my little brother, thank you."
