Okay this is my first fan fiction ever, so sorry for any mistakes, still trying to get the hang of it.
Jack's POV
Jack Frost guardian of fun was down in the dumps; Jamie, Cupcake and the other kids had almost grown-up and were now teenagers, about 14-16 years old and had stopped believing. As a result he was back to square one, having been unable to convince other kids he existed. I mean it was hard enough before when no one believed in him, but at least he'd had hope that maybe one day they'd believe in him and now that it had happened, but had been taken away from him, well his hopes were burning low.
It was November, mid-winter and strolling along the high street in his home town Burgess; he couldn't see the point any more. Catching sight of his former best friend and first believer he flew after Jamie, hoping against hope that somewhere in Jaime's mind he would believe again.
Gliding along beside him and waving his hand in front of Jaime's face, leaning on his staff, he called "Hey Jaime, remember me, it's your buddy jack, Jack Frost"
Jaime did not even blink, let alone turn around, he continued determinedly along the high street dodging early Christmas shoppers. All Jack managed to do was cause ice to form on the pavement causing numerous shoppers to slide all over the place. Great jack thought, I never should have left for the summer.
Leaving for the summer when Jamie had just turned 13, was Jack's big mistake, over that summer Jamie had decided that he was too old to believe, having recently become a teenager, his Mother insistence that he was too old to have imaginary friends and Jack's absence, caused his belief to wither and die. His friends too began to doubt the existence of jack frost and they too with their parents instance and the fact they were being bullied as the 'Frosty Freaks' , stop believing in Jack too.
Jack's hopes were crushed in an instant and slowing to a halt he turned around and felt the all too familiar feeling of people walking through him, making him feel insignificant, small and unloved. Placing his feet on the pavement which rapidly froze, he turned the corner and crashed straight into a teenage girl around 14, who had been franticly running down the street. Jack barely had time to think 'What she believes!' before the girl picked herself up and blurted a quick "I'm so sorry" before she dashed off again, her white scarf trailing behind her, leaving behind a green woolly hat with a white pom-pom on the top, which had been knocked off during her haste. Picking up the discarded hat he looked inside to see if there were any name tags. There were none. "I HAVE A BELIVER" jack screamed, jumping up and down with joy, racking his hands through his hair "AND SHE SAW ME AND EVERYTHING" "YAHOO!" He cried doing a somersault in the air. "My first teenage believer" he said breathing heavily and gasping for breath. "I've gotta go after her." He sped after her, wondering who, was this mysterious girl who believed.
