Elsa stood at the window of the room she'd slept in since she was a child looking over her sleepy kingdom in her nightdress, her stomach full from dinner and her white hair loose and flowing in the soft breeze. She rested her elbows on the still, rested her chin in her palms and stared at the moon as if waiting for something. She had done this many times before as a way to clear her head of the conflicting thoughts flying around.

Tonight, like she had done most nights since that moment, she thought about that night years ago when she had seen someone at her window. She was only a little princess but she could remember clearly the frost covered blue hooded jumper the figure wore and the staff he carried as he flew from her window into the night.

Because of her young age, she sometimes second guessed herself but she was so sure he had been really there, that she hadn't imagined him. She couldn't explain it but, she felt like he was her friend.

The thoughts in her head turned into question as they whirled around, making her more and more confused by the minute. Who was this man? Why couldn't she forget him? Why had he been there and, most importantly, why hadn't he ever returned?

Elsa pulled her gaze from the moon and sighed. She stared at the moon while she thought about him because it was what she'd seen him doing before he disappeared. She hoped it would connect her to him or give her some answers.

Defeated, she turned away from the window, like all those other times ending in the same result, and slipped under her bed covers, pulling them up to her head so it stuck out, just like it had all those years ago, and thought of her sister as she waited for sleep to claim her from this lonely night.

'I know I was supposed to watch her. I have been but I can't be on her 24/7.'

Silence.

'What do you mean "not effectively"? I have a life of my own too you know!'

Silence. The wind whistled past the flying figure as he soared through the sky.

'Yes I know it's been a while but I'm pretty sure it hasn't been 16 years.'

The figure fell silent for while, appearing to listen to an invisible voice.

'Come one Man in Moon, you're so annoying. Jack do this, Jack do that. Jack go to the toilet. Jack fetch my hairbrush. I mean, come on. You don't even have hair!'

Silence.

'I am funny and you know it. You just can't admit that I'm right.' Jack listened for a few seconds. 'Fine, I'll go there now,' he grumbled and turned his body around, flying towards castle Arendelle.

To an outsider, Jack Frost would have been perceived as crazy, but he was just as sane as you or me. 16 years had passed since Jack Frost had first visited Elsa and Man in Moon wasn't too happy with him and now he flew through the ice cold night air, not that that bothered him, to castle Arendelle to pay a "little girl" another visit.

Jack Frost perked up as the castle came into sight. It looked, to him, just the same as it had 16 years ago. Flying up to one of the windows, he looked in, expecting to find a little girl. The room was empty. Puzzled, Jack entered the room and looked around for any sign of the little girl he was supposed to guard.

He went over to the double bed situated in the middle of the wall between the window and the door. Looking under the bed, he pulled out a mysterious brown sack. Opening it, he spilled its contents on to the bed. Carrots and a grappling hook? He was puzzled. Why would a little girl own these?

He heard voices in the hall outside and shoved the items back into the bag and dived under the bed with the bag in hand.

Hearing the door to the opposite room open, he breathed a sigh of relief. He crept out and pushed his ear against the door.

'Your majesty is there anything I can get you?' he heard someone, presumably a servant, ask.

'No, no it's fine,' a female voice replied. 'I was just going to retire for the evening. I'll see you in the morning.'

'Yes, yes. Very good. Well good night Queen Elsa,' the servant responded closing the door. Jack heard her footsteps fading as the servant walked away.

Elsa. The name stuck in his mind. She was the girl he was supposed to find. But the servant addressed her as "Queen". Jack flew out the window, cursing his stupidity to have flown into the wrong room.

Rounding the tower, he saw her. Staring at the moon, like he did sometimes, as if waiting for something. Could this girl have possibly already learnt how to control her powers? Could she commune with the man in moon too?

Hidden from her sight on the roof above her he watched as she sighed and moved away from the window and into bed.

Debating whether to speak to her now or later, he flew away, eventually deciding on the latter. Taking refuge in a hut on the mountains, Jack sat down and planned out what he was going to say to the girl when he planned to confront her the next evening.
