A/N: Ok, people, second chapter!!! Enjoy and review!! Oh, and the rating is high because of some violence and death later on.

The first thing she was aware of was the steady thumping of her heart. Then she felt the cold steel her arm was against, and the wire mesh she was crouched on. Opening her eyes, she saw, for the first time, her sanctuary.

**Flashback**

Walking down the street, coming back from the shopping centre, she heard heavy footsteps behind her. Her breath came out in icy sheets as she picked up her pace, unable to see very far behind her thanks to the thick December fog.

'Hello darlin',' called out a voice behind her, and raucous laughter followed. She sped up, but she knew she was in trouble. Glancing behind her, she saw the lit ends of cigarettes through the fog. So there was more than one of them. She realized they must have come out of the pub when she passed it. She cursed herself for leaving it so late to go home, and for not charging her phone up.

'Aren't going to stop and talk to us, eh?' The voice came again, followed once more by cackles. Then someone grabbed her arm. She shrieked, and hit the offender over the head with her bag.

'Now now, play nice.'

She felt herself fall, and soon she was face down on the damp grass beside the pavement, mud in her mouth, terror coursing through her. There was someone sitting on her back and her legs, forcing her into the ground. Turning her head to the side, she saw a cigarette put down near her face. Wrenching an arm free, she managed to pick it up, and press it onto the arm of the person on top of her.

'She burnt me!' They swore and the pressure on her bag and legs lifted.

She got up, hit the other over the head with her bag, and ran for it.

Soon her legs were aching and her breath laboured, but she couldn't stop. She could hear their footsteps behind her, and she knew she had to hide. Suddenly, she tripped, and fell on something sharp. Her jeans ripped and she felt a sharp pain in her leg, but she struggled back to her feet and kept on going.

Doors! There was a strange box on the side of the street. She opened the door, and flung herself inside. Shutting it behind her, she hid in a dark corner, so scared and in so much pain she spared no glance for her surroundings. Crouching down, she succumbed to the pain, and everything went black.

**Ends Flashback**

She tried to forget what had happened, but that was ridiculously easy once she saw where she was. The box hadn't looked this big from the outside…

Getting up from the dark corner she had hidden in, she gasped and sat down again quickly. Her leg hurt badly, and when she put her hand over the slash in her jeans, she felt something warm and wet. Blood. Gritting her teeth, she undid her belt, and wrapped it around her thigh, above the cut, and tightened it, to stop herself losing too much blood. As soon as she got out of there, she needed to find a Doctor.

She walked over to the main pillar in the middle, and stared in wonder at the lights flickering on it. For some reason, though, it didn't look very healthy. The lights were pale and weak, and strange groaning noises came from under the panels.

Looking over her shoulder, she saw two doors. Sighing with relief, she went over to them and opened them. Only to shut them almost straight away. The box had moved. It was no longer on a foggy street in Egham, but in a corridor that belonged in a castle. She looked wildly around for another door, and saw one at the other end of the mesh platform. Running over to it, she flung it open, but there was just a corridor, with the same mesh floor as in the main place, and lots of rooms. And she distinctly remembered running straight into the main control room. At least, that was what she thought it was.

Swallowing the urge to break down into tears, the girl decided to have a little explore. The box can't have moved that far, could it? It would also keep her mind off the fact she was lost, with no battery on her mobile phone. Not that she liked her home much. She hadn't liked her house since her parents died in the car crash. She lived with her Aunt, who hated her. Her life had been bearable 'till about a year ago, when her loving Uncle Henry had died of a heart attack. Then she'd been left on her own with her Aunt Millicent, or malice, as she liked to call her.

A throb from her leg reminded her of her predicament, and she slipped out the doors…

'What… you're an alien?' squeaked Ginny.

'Yeah.'

'You look very human to me,' said Hermione, looking at the Doctor unbelievingly.

'Nope, two hearts,' he said.

'Cool,' said Ron. Harry just looked awkward. There was a silence.

'Soooooo… you might be a wizard then?' said Ginny. The others looked at her, glad at the subject change.

'I might be,' he raised an eyebrow.

'Are we going to the kitchens or not?' asked Ron, grumpily.

'Honestly, Ronald, your stomach is not the most important thing at the moment,' snapped Hermione. They bickered all the way to the kitchens, before the house elves supplied them with enough food to keep his mouth busy.

'Can we see your spaceship? I don't remember seeing anything but a funny blue box when we bumped into you,' said Hermione.

'I need to go back to the TARDIS anyway. I'll run a few tests, but I doubt it'll work on the Hogwarts grounds.'

'It won't. Nothing electrical works here,' said Ginny.

'We've already told him that,' said Ron round a mouthful of chocolate éclair. The girls looked at him disgustedly.

'I don't know how you can eat chocolate for breakfast, Ron,' said Ginny wrinkling her nose. Harry grinned.

'What does the name TARDIS mean anyway?' he asked.

'TARDIS stands for Time And Relative Dimension In Space,' said the Doctor.

'What… so it's a time machine as well?' asked Hermione, amazed. The others just looked confused. The Doctor was pleasantly surprised.

'You're really clever, for a human. Didn't I say it was magnificent and high-tech?' he asked, grinning cheekily.

'I'll take that as a compliment,' said Hermione.

They reached the TARDIS, and they didn't look impressed.

'This is a time machine?' asked Ginny.

'And a spaceship?' asked Harry.

'It doesn't look like it could get off the ground without a strong levitating charm,' snorted Hermione.

'Oi, don't knock my spaceship,' said the Doctor. He was about to open the door, when it opened by itself, and a girl came out.

'What the…' the Doctor said. She looked pale and drawn, with her dark hair hanging matted around her face, her black skinny jeans and once-nice top splattered with mud and what looked like blood. She walked straight into the Doctor, fell back against the TARDIS, and hit her leg. Her face went, if possible, whiter, and a gasp of pain escaped her mouth. She fell back, unconscious. The Doctor caught her before she hit the floor.

'Hello, you weren't in there before.' He laid her down on the floor. 'Does she go to this school?' Hermione, who had her hands over her mouth, shook her head. Harry joined the Doctor on the floor by the girl's head.

'She looks about our age, but she's not wearing robes, and I don't remember seeing her before. I wonder who she is.'

'She must be a stow-away. Well, she's stuck here with me until we figure out a way to get the TARDIS out of the energy field.' Hermione joined them on the floor.

'We need to get her to Madam Pomfrey,' she said.

'You're a Doctor, aren't you? What's the matter with her?' asked Ginny, crouching next to Harry, who blushed again. This did not escape the Doctor, but he needed to focus on the girl. He whipped out his sonic screwdriver.

'What's that?' asked Hermione, as he waved it along the girl's body.

'Screwdriver,' he grunted, as he concentrated on the readings. 'Whoa, what happened to you?'
