Cathy woke up to the feeling of a small chill over her face to find her windows open with the curtains blowing gently in the breeze. She sat up and rubbed her eyes which were still sleepy and fuzzy to find a tall figure crouching on top of her bed end frame. She rubbed her eyes again to confirm her suspicion but she wasn't in another one of her day dreams, it really was Jack Frost in her room. "Jack!" she shouted running over the top of her bed to give him a hug. Jack returned the hug as Cathy nuzzled her face into his cool chest. "Morning Cathy, did you sleep well?" he asked turning his mind back to the previous night when she was tossing and turning in her sleep. She looked up at him and smiled "Yep! I had a dream that we went flying!"

Jack smiled at this reply and jumped off the bed frame to look around the room again, getting a clearer look at the picture on the wall. "Did you draw these?" he asked with a small grin.

"Yep!" Cathy said also jumping off the bed and looking at her wall "I wanted to make sure I never forgot". Not long after Cathy had finished her sentence her mother walked in the room to see Cathy already up. She looked at her before taking out her clothes as usual, "another snow day today so you know the drill" she said hurriedly and left the room. Cathy's eyes were wide open by now, how did her mother not see Jack in her room? Jack obviously knew what she was thinking and ruffled her hair "only people who believe in me can see me". Cathy thought about this for a moment before nodding showing that she understood before taking her clothes into the bathroom and quickly getting ready.

"Jack?" she said leaving the bathroom to find Jack gone. She looked around her room wondering that if he was hiding before she heard a bang from downstairs. She raced down into the kitchen to find boxes of cereal all over the floor and Jack crouching on the table. "Sorry, I opened the cupboard and they all fell out" he said getting off the table and beginning to pick up the boxes. Cathy giggled and began to help clean up before picking up her usual box of cereal and placing it on the table along with a bowl, spoon and milk. Jack looked at the box on the table curiously "Cocoa Pops?" he said.

"Yea, it's a chocolaty cereal, you never had it?" she said looking at him with which he replied with a shake of his head before turning his attention back to the box. Cathy took another bowl and spoon out before pouring the cereal and milk into the two bowls and sitting down. "Try some, it's tasty" she said taking a spoon full and eating it. Jack sat down next to her and also took a spoon full before his face lit up "wow this really is good!" he said before scoffing the rest down. Cathy giggled at his reaction before continuing with her cereal. "Do you like lots of chocolaty things?" she asked curiously.

"I don't need to eat so I don't get to try many things" he said finishing off his bowl. Cathy also soon finished and took the two bowls before washing them and putting them away. Once she had finished she turned to Jack and looked him over. "Have you still got that scarf?" she asked still looking at him. He slowly reached into his pocket and pulled out the scarf she had given him "I didn't want to lose it while flying, the wind can be pretty strong" he said wrapping it round her neck. She smiled and nestled her face into the soft scarf.

Jack then walked over and picked her up onto his back which made Cathy gasp "want to go flying?" he said grinning as usual. Cathy quickly replied but nodding her head violently as Jack ran up into her room with her still on his back and over to the window. "One…two…three!" He called before jumping out of the window which caused Cathy to let out a small scream but she soon stopped when she felt the wind carrying them along which changed the scream into a joyous laugh. They flew around the town seeing people playing in the snow and building snowmen when they came across the two boys from the other day. A devious thought then came into Jacks mind as he landed on a nearby rooftop and created one of his special snowballs. He held it out in front of Cathy and pointed to the two boys "give it a shot" he said. Cathy looked slightly worried at this idea; it wasn't like her to do something like that. Jack gave her a reassuring smile which washed all the worries away and she took the snowball in her hand. She walked up to the edge of the rooftop and aimed the snowball at the two boys. She quickly threw it but it didn't look like it would travel far enough so Jack used his powers to give it an extra boost and just before it was about to hit one of them it split into two and hit both on the back of the head. Jack quickly pulled Cathy behind the chimney so they wouldn't see her as they both started giggling at the sight of the two confused boy wondering who threw the snowball. They continued messing with people and having fun that day until sunset and promised to do it again sometime.

Jacks visits had become far more frequent and each day was better than the one before, filled with new adventures and new ways to have fun. Cathy's life had changed with the influence of Jack in it and it was like a new chapter of her life filled with fun and joy. Her mother had also noticed the change in Cathy's wellbeing and believed that her imaginary friend might be a good thing.

It had been two months since they had met and Jack was playing in the open field in the woods with Cathy as usual, having snowball fights and ice skating on the frozen pond. Cathy had become an excellent skater with the constant practice and expert advice of her ice loving friend.

One day, Cathy and Jack were having a snowball fight which Cathy seemed to be winning. Although Jack could make them quickly Cathy's aim had improved massively and almost every shot she made hit Jack while Jack's shots almost never hit Cathy.

"Come on stay still!" he said throwing snowballs rapidly.

"No way!" Cathy said expertly dodging them before landing a shot in the middle of Jacks face.

He quickly wiped the snow away from his face "that's it!" he said grinning and threw a snowball directly at her face which she expertly dodged but the snowball continued to fly and made a hit on a different target. "Arghh!" they heard a voice say and quickly turned around. Standing there was a tall fluffy creature with markings on its fur and carried a boomerang with snow covering its face. Cathy was shocked to see something so big and quickly ran behind Jack for protection.

"It's Ok kiddo, it's just a kangaroo" Jack said chuckling at his joke.

The creature then wiped the snow away to reveal a large rabbit with grey fur and a stern expression. "For the last time, I'm a bunny!" he stormed across the field until he was face to face with Jack.

"I'm still not convinced, what do you think kiddo?" Jack said turning to Cathy who was still confused at what she was seeing. She looked at the creature from head to toe and could understand why Jack might think that he was a kangaroo and the accent didn't help. However, it was clear by the tail that he was indeed a rabbit. Cathy giggled thinking that she was wiser then Jack "he's a bunny Jack, you can tell by the fluffy tail!" she said pointing at it.

Bunny hadn't noticed the child and looked at her before looking at Jack again "who's the smart kid?" he asked.

Jack then picked Cathy up onto his shoulder and smiled "This is Cathy, Cathy this is the Easter Bunny" he said introducing them both.

Cathy also smiled and reached out her hand "it's nice to meet you Mr. Easter Bunny"

Bunny then shook her hand "you too Cathy" he said before turning his attention back to Jack "how long have you been around this kid?" he asked with a curious tone.

"We met at the beginning of December and have been hanging out ever since" he said happily before placing Cathy back onto the floor.

This changed Bunny's expression back to a stern one "mate we need to talk" he said glaring at him "drop Cathy off back home and head over to the North Pole". Bunny then thumped his foot on the ground and a large hole appeared which he quickly jumped into and instantly disappeared.

"Jeez what's with him" Jack said confused before picking Cathy up "looks like it time to head back".

They then were both whisked into the air and travel by wind back to Cathy's room. He quickly dropped her onto her bed before giving her the usual goodbye hug and heading out towards the North Pole.

Once Jack had arrived he noticed that the rest of the Guardians were also present. "What's this, some kind of team meeting?" he said taking his usual spot on top of a desk. Tooth then looked over at him and a sad frown appeared on her face which was rarely seen over her joyful exterior. "Jack it's about this child you're playing with…"

"You mean Cathy? What about her?" he said leaning in slightly.

They all then looked at each other before Bunny took over "you have to stop seeing her" he said bluntly.

Jack was shocked to hear this from his friends and immediately stood up in protest "why? She hasn't done anything wrong! She's a nice kid!"

"Yes and that's the problem" North stepped in "you like her too much, she's become your favourite child"

"So?" Jack said grumpily.

"As Guardians we can't have favourite children" North continued "think about it, if you want to keep playing with her then you have to stay around in the summer, and if you are there in the summer you will create snow. It would mess up the balance of nature!"

"So I'll just play with her in the colder months, simple" Jack said walking over to North.

"No, not simple Jack. Look this has happened before" Tooth cut in "Bunny had a favourite once, they were great friends but as this child got older they started to get bullied really badly for still believing in the Easter Bunny and…" she stopped not wanting to continue.

"And?" Jack said wanting to know what happened.

Bunny slammed his hand down on the desk in anger "They took their own life Jack! They took their life and it was all my fault! Kids have to grow up and stop believing in us or bad things happen! You have to end it with that kid!" he said with the threat of tears in his eyes.

Jack looked shocked at Bunny's expression. He had never seen him like this before, not even when he ruined Easter for him. It was just a whole new level of anger and sadness. It finally dwelled on Jack the decision he had to make.

"Jack, if you really love Cathy… then you will let her go" Tooth said placing her hand on his shoulder. Sandy also came over to comfort Jack and gave him a reassuring pat.

Jack looked up at his friends knowing that he needed to do it for Cathy; he didn't want her to have the same fate as the other kid. "Ok I'll tell her tomorrow…" he said before walking away.
