"Get out! Get out of my house you monster!" Luna raced up the stairs at the sound of her father's voice. She nearly ran headlong into the doctor, who was making his way back down the stairs, his hands raised in a defensive gesture.

"What did you do?" Luna gasped as a spell burst on the wall above them.

"I did nothing!" The doctor gasped in a mildly panicked voice. He had just run up there without thinking about it at all, but Luna found she believed him. Her dad would never over react like this, he loved it when strangers came to visit. They would sit and have terrible tea and talk about the quibbler. Not this.

"Dad!" Luna said angrily, marching past the doctor into the study. She had enough time to register that the dark spot had grown, looked like some sort of creature, before the doctor cried out.

"No!" He shouted, pulling her back down the stairs as another spell exploded where she had just been standing. The doctor picked her up and ran right out the house. "A wise man always knows when to retreat." He muttered as shouts of "And stay out!" Followed them to the front door.

"Are you good? Fine? Dandy?" The doctor asked as he scanned her for any signs of injuries. The continued walking across Luna's front lawn, but she barely noticed where they were going, or what he had said. Her father had tried to hurt her. Maybe it was an accident, but she had come way to close to being hit by a spell.

"Whats wrong with my dad?" Luna asked. Finally the doctor stopped walking and looked down at her. He had seemed like an over confident young man when she had first seen him, but now as he struggled to find the right words, he seemed ageless, wise, and very very sad.

"I didn't get a very good look at it, but I'm pretty sure I know what is was." He said slowly, continuing to walk. Luna looked up and noticed the blue box for the first time. She had never seen anything like it before, and it was beautiful. "I just need to run a few scans in the Tardis, and you can stay with me until I can fix this up." Then he seemed to consider his words and looked at her sheepishly. "That is, if you want to of course."

Luna was still trying to comprehend what he had said about her dad. That thing by him, that had to be part of her imagination. "What what was?" She asked in irritation. "Have you never seen a wizard before?"

The doctor stopped just before the blue box, his hands on the handles. He stared at the windows, as if they had the answers Luna wanted. "That was your dad yes, but the thing next to him..." He trailed off and opened the door. "Well, give me a moment and I'll know for sure what it was." He repeated, stepping into the box.

Luna gave a small sigh and followed him in, she couldn't fix any thing by herself. She wasn't quite sure what she had been expecting when she stepped into the box, she hadn't thought about it very much. Maybe a bit of junk, since he had been talking about scanners, or maybe a fireplace so he could use the floo network, but she had not been expecting this. Inside the box was enormous, which was not the surprising bit. Luna stared in wonder at the gleaming console that sat in the center of the room, where the doctor was flipping levers and looking intently at a screen. There were so many buttons, switches, things to be pulled and tugged, Luna even saw a coat hanger poking out.

"It's wonderful." She breathed as she turned around to take in the rest of the ship. It's high ceiling with strange orange lights, it had stairs that lead out of sight which meant more rooms, and there was even a space underneath the controls.

"Isn't it? I just love this bit. Bigger on the inside and all." He smiled back at her, taking time to look up from the screen.

"Undetectable extension charm." Luna nodded knowingly. I've seen my dad use it before."

The doctor puffed up his cheeks indignantly. "It is not some spell- oh never mind, you wizard folk are so gosh darn impossible to impress!" He turned back to the screen.

"What are you doing even?" Luna asked, walking up behind him. She could see her own house on the screen he was looking at. A few wavy lines were crossing the screen every few seconds, and every time a new number showed up on the left side.

"I'm scanning the house for it's extraterrestrial aura levels."

"What?"

"I'm looking for aliens." He said, leaning back on his large feet. He smiled at her and fixed his odd little red bow tie.

"Aliens?" Luna replied a bit skeptically. She was ten now, and that made her a grown up, so she didn't believe in sill things like aliens or Santa Claus anymore.

"Yes, Aliens. I think a leech like creature, is feeding off your dad's negative emotions, making him angry." The doctor replied seriously. Somehow, Luna felt that he was right. Maybe she wasn't sold about the aliens bit, but her father's anger just wasn't natural.

"And what can we do about it?" Luna asked, leaning against the Tardis console.

"I'm working on that too." The doctor frowned. "Give me time and I will fix everything, I promise."
