'What?' Growled Jack as he approached North. Why on earth had he summoned Jack to the North Pole again? As he observed North's face however, he could tell that something was wrong. That cheerful smile was no longer on his face and his brow was furrowed.

'What?' repeated Jack, but in a softer tone this time.

'Pitch.' He replied simply.

Jack closed his eyes in frustration, 'brilliant. What on earth is he doing?'

'What do you think?' sighed North, 'just the usual. Causing darkness, fear and confusion over the lands. Canada in particular.'

'Canada?' Snorted Jack the ends of his mouth twitching, 'why on earth is he bothering with Canada?' Then Jack looked up into his eyes and couldn't help asking, 'why are you telling me this?'

'Because I've got a little task for you to do,' said North.

Jack groaned, 'why can't you get tooth to do it? She's enthusiastic enough.'

Acting like he hadn't heard this, North expanded, 'I got a message from the moon last night,' at this Jack's eyes widened as North continued, 'it told me that there is one person, and one person alone that has a chance of defeating Pitch for they alone, know his weakness.'

'Wait, it's not me is it?' Inquired Jack uncertainly.

'No,' answered North quickly, 'I just want you to find this person and find out what their secret is.'

'Phew,' Jack sighed in relief, 'so how do I do that?'

'Well,' explained North, 'I've got the address so you can get there. Really, you just have to use them to defeat Pitch.'

'Okay, but after I find them, how do we get to Pitch?'

'Sounds like he's taken over another Island,' said North gravely, 'and he spends almost all of his time there. He's probably trying to create an empire of darkness starting with there.'

'Okay,' murmured Jack uncertainly, 'when do I fetch them then?'

'Well now of course,' North exclaimed before picking Jack up with one muscly arm and steering him towards the exit, 'go on then.'

'Okay okay,' complained Jack, tugging himself out of North's grip and walking towards the exit himself, 'I didn't know being a guardian implied that I had to get carried by the scruff of my neck and do chores.'

Thus, Jack had no choice but to go to the address that North had handed him and track this person down. What was he going to say to them? If they were powerful enough to defeat Pitch, then clearly they were powerful enough to harm Jack himself.

He found, however, that whoever it was lived in just a little cottage. As he approached the door, he looked up at the moon shining above the house in the navy sky.

Why this place? Of all places. This was the last place that Jack would expect anything special to happen. He checked the piece of paper that North had given him. At the bottom it read: Top left window is their bedroom. Jack leapt up onto the window ledge and peered through the misted window.

He couldn't see much. The bedroom was quite plain but there was definitely someone in the bed. Slowly, he creaked open the window and crept inside the room.

Jack craned his neck, trying to see who it was that was destined to defeat Pitch. However he didn't watch his step and he accidentally tripped over a beanbag and stumbled.

The noise woke whoever was in the bed because immediately, they sat up straight. There was one second where they just stared at Jack. A girl, no older than sixteen was gazing, dumbstruck at Jack.

She had big deep blue eyes and long shining black hair which was tied back. Moreover, she didn't appear any threat to Pitch or indeed Jack. Perhaps he had got the wrong bedroom.

'What the hell are you doing in my bedroom?' She hissed.

'Look,' said Jack, getting straight to the point, 'basically, I need you to come with me. You have to do something,'

'Wait,' she interrupted, getting out of bed and approaching Jack, a suspicious look on her pale face, 'who exactly are you?'

'Jack Frost,' sighed Jack. He received no reaction whatsoever. 'Jack,' he said, more clearly this time.

She just looked at him, 'yeah I heard that.'

'Haven't you heard of me?' He asked.

'Are you a religious person or something?' Queried the girl, 'because this town ain't very religious.'

'No,' replied Jack scowling, 'I'm- oh it doesn't matter. Point is you need to come with me to get rid of Pitch.'

'Who's Pitch?'

'You have got to be kidding me,' he exclaimed, 'the moon chose you to defeat Pitch when you don't even know who he is.'

'Oh please,' she snorted, 'speak English.' Jack glared at her.

'Please, I'll explain later. You just need to come with me.'

'You broke into my bedroom!' She protested, 'I haven't got a clue who you are.'

Taking a deep breath, Jack explained in detail, everything that North had told him and about Pitch and what he did.

'You're mad,' she sighed simply.

'So you're not coming?' Asked Jack.

'Oh, no I am coming,' she said quickly. Jack looked at her in surprise and then smiled.

'But can I get dressed out of these first?' She asked, gesturing to her pyjamas. Jack nodded. After she'd got dressed, he held out his hand. She looked at it for a second before taking it. Immediately, Jack rose into the air and flew out of the window. Taking by surprise, the girl screamed. They landed on the roof of the house.

'Sorry,' said Jack, 'I didn't get you're name. What was it?'

'You can fly!' She panted, staring at him, 'you can fly! How can you fly? You just flew.'

Jack nodded before muttering, 'thanks for agreeing to come. I can't believe you actually did agree though.'

There was a moment of silence between them.

'So,' sighed Jack, 'what is your name?'

'Elisa,' the girl said stiffly.

'Okay Elisa,' smiled Jack, 'lets go then.'

'Okay,' she nodded, 'but get me back home by next week.

'Why next week? What's happening then?'

'Nothing,' she murmured, 'and if it were I wouldn't tell you. Still bear in mind I hardly know you.'
