Spirit of Summer and Winter

Chapter 1: Wish I Knew

As cold as he was, her skin brushing against his had brought warmth to him. Most of the times they were on opposites ends of the world, but they never let it keep them apart. They sat a top of one of the roofs of Arendelle and watched the last bit of light leave the city. A summer breeze blew, curtesy of Anna. Jack couldn't help but add a little bit of winter air to balance it out.

"How is being a guardian?" Anna asked, breaking the silent.

Jack looked at her. He'd known her for most of his immortal life. Who could forget running into high spirited spirit of Summer? That was surely a day he'd never forget.

Both flying at high speeds and then "crash!"

"You should watch where you're going?" Jack told them off as he got up. He was surpised to see it was a girl in braids, no older than his physical age.

The girl got up and frowened. "Well you should too." she retorted. She noticed bits of frost clinging onto her dress and she melted it off. That was when Jack noticed parts of him were melted and in a matter of seconds, the missing frost formed again over his cloak.

"Oh. So you're the infamous Spirit of Summer?"

Anna looked up at him. "Yeah..." she blinked.

"Anna Dawn, wasn't it?" he remembered hearing her be mentioned a couple of times, but he thought he'd keep his distance, seeing as winter and summer were complete opposites.

"And judging, by the white hair and frosty look, you're Jack Frost."

"Right, milady." he bowed. She honestly didn't seem as bad as he thought. How she looked and talked told him she wouldn't hurt a fly.

That day had been a great day. She was just as fun as he was and they spent the day playing around and well...just having fun. It beat the loneliness he had and like him, no one could see her, unless they were like them.

"It's great. Finally being seen and being able to inte..." he noticed the upset look on her face and stopped. How could he have been so insensitive? His best friend.

Anna realised his stopped and she hoped it wasn't because of her, but she knew him all to well. "Don't hold back on me Jack Frost." she pointed her finger at him. "Don't start feeling sorry for me everytime I frown. I ask you a simple question and I expect you to answer it."

"Fine." he sighed. Anna sure was feisty. He'd end up losing arguments or giving in every time she had a fit. He was stubborn himself, but when it came to Anna he was beat. "I'll just stick with, it's great." that was the truth and he wasn't sure how else to describe the feeling.

Anna raised an eyebrow, but brushed it off and just went with it. "Tell me more about your past life. You know, before you became Jack Frost."

"It's all pretty much a blur." he admitted. "But I do remember always playing jokes on my sister." he laughed.

Anna smiled. "I wonder if I ever had something like that." she said taking a breath and looking up to the sky, which was now being lit by a full moon.

"I know you had some kind of life before who you are now."

"How?"

"Because everyone like us were all someone before being chosen."

"But all I can remember is waking up in a frozen waters and then suddenly the sun is shining and the water begins to melt. It suddenly becomes a nice summer day and then I find out that no one can see me."

"Hey." he held her chin up to look at him. "You'll figure out your purpose one day. That you can bet own." he smiled and he managed to get a smile on her face. His icy blue eyes, locking onto her sky blue ones.

The moment was interrupted when the northern lights spread across the sky. "Oh look, the sky's awake." Anna giggled and then watched them in awe, she then turned to Jack. "Do you have to go?" she knew what he was going to say, but wish he didn't have to.

Jack nodded. "I promise, as soon as I'm done, I'll meet up with you."

"Where?"

"Uhm...Burgess."

"Okay." she laughed slightly. "Hurry back." she waved as he flew off into the night.

AN: I know I have like a bunch of other stories I need to go and update, but I just wanted to do this idea. Just so you know what's going on, This is AU from Frozen on a "what if Anna wasn't thawed" scenario. I'll be getting more into that later on. This is more of an intro chapter on Jack and Anna's current relationship.

So, read, enjoy and review.
