So I'm feeling quite keen on really getting into the story, so here's chapter 3 already. The next chap is going to be a little more... involved, so I probably won't be posting the update so quickly as this one.

As ever, I'm keen to hear what people think! Thanks so much for the reviews left so far. It's helpful to know what people like to hear when considering how to write the next stuff!

Ok, force-fields, Amy thought at first walking back down the corridor, stretching her arms out and expecting to hit some sort of barrier. There was none. She passed the point where the TARDIS had been. I'd have heard it if the TARDIS had left, so it must still be here somewhere…

She wandered back and forth down the corridor, her breathing growing more and more rapid as the panic started to set in.

"Doctor?" She called out, her voice echoing around the metal chamber she now found herself trapped in.

There was no reply. The Doctor wouldn't have left me, she told herself, trying to calm down a little. Something else must have happened. So do I stay put and wait for him to sort it, or shall I try and figure this out for myself?

Amy didn't really have to give this question a whole lot of consideration. She was not the sit-patiently-and-wait type. She headed over to the door with the least amount of concerning claw marks and put her hand out to try and see if she could push it open.

Her hand simply passed through it. Overbalancing by the unexpected lack of obstruction, she fell, head-long through the doorway, and found herself in a similar corridor to the one she had just been in. She looked back. Her legs hadn't made it all the way through and her feet were still hidden from view, still on the other side of the ghost-door. She quickly got to her feet and waved her hand about in front of her, watching it move in and out of the door like it wasn't there.

She wondered if it was a kind of hologram, and made a mental note to ask the Doctor about it later when she found him. If you find him, said a voice in the back of her mind. Trying to brush this thought aside, she turned her attention to what now lay before her. It was a similar corridor, this one now veering off to the left and the right, with more doors down the sides of the walls as well as at the end. She walked forwards towards the fork in the paths and wondered which way to go. Both looked identical.

She went left.

The Doctor hadn't moved. He was still looking around at the corridor, trying to see anything definitively or even partially helpful. There wasn't a whole lot.

"Who're you?" Said a voice behind him suddenly.

His head whirled around. Now stood at the far end of the corridor was a young woman. She wore an old, filthy lab-coat, pinned to which was an ID badge of some sort. Her hair was tied back in a dishevelled bun, and the general appearance of her was not of someone well-cared for.

"Hello," the Doctor said cheerfully. "I'm the Doctor."

"Doctor who?" asked the woman uncertainly.

"Nope, just 'The Doctor'. What's your name then? And where is this exactly?"

"This is the storage deck. My name is Dr. Flannigan" said the woman, watching him warily. "What's your clearance?"

"Oh well, that'd be the highest of all the clearance's," the Doctor replied, flashing his psychic paper as he walked towards her. "Just…um, the storage deck of what?"

"Where did you come from?" Dr. Flannigan asked, giving the Doctor a fearful glance.

"I could say the same to you," the Doctor replied, looking at her analytically. "Just popped out of nothing a moment ago without warning or even a decent 'pop'. Do you know what's happening here?"

"You're not one of the crew," said Dr. Flannigan, taking a step back, her voice trembling with fear. "But you don't seem like one of… them."

"Who's 'them'," the Doctor asked softly, "And why do they have you so scared?"

"There's no time," Dr. Flannigan whispered.

The Doctor grinned reassuringly. "Actually time is the thing I've got plenty of. What's happening here?"

He blinked. As his eyes opened again, Dr. Flannigan wasn't there. He jumped back, eyes wide.

"Well that's very highly unusual and not at all good," he muttered to himself, fumbling with the sonic screwdriver and never letting his eyes wander from the patch of air where Dr. Flannigan had previously been stood.

He waved the screwdriver around in the air in front of him, the whirring echoing back down the corridor. He sighed as the device told him nothing of any use. Not transported, he thought to himself. Not invisible, not dead just… not here. Vanished.

For a brief moment all he felt was the thrill of a new challenge, and a half smile flashed across his face. Then everything else caught up with him and his smile quickly disappeared. Where had Dr. Flannigan vanished to? More importantly, where had Amy vanished to?

He sat down on the floor and leaned back against the door. He drew in and then released a deep breath of air, and closed his eyes, bringing Amy's face to the front of his mind. He couldn't help but smile as he recalled the features of her face. Her flowing red hair, her dazzling smile, her mesmerising eyes… and then, concentrating very hard on her image, he opened his eyes again.

She still wasn't there. He sighed. Well it was worth a try, he thought, before setting to work trying to open the door.

"Quickly run!"

Amy screamed in surprise as the large, grubby man grabbed her arm and practically dragged her down the corridor.

"Oh my GOD, where the hell did you come from?" she shrieked, as she jogged to keep up.

"We don't have time, we have to run!" the man said sharply, urging her to move more quickly.

"Time for what?" said Amy, "What's happening?"

"They're coming, that's what's happening!" The man barked impatiently. "Now move your red-headed-arse before I just leave you to it!"

"I don't understand, what's coming? What's happening? Where is everyone?"

The man looked at her critically, as if coming to a decision. "Listen, you have to keep running if you see one of the beasts," he said in a hushed but hurried tone. "Don't trust anyone you can't touch and keep moving. If you find anyone then ask them to explain it all better. You'll catch up soon enough."

"Wait, where are you going? Can't I stick with you?" Amy asked, as the man glanced behind them nervously. She looked back the way they had come, but she couldn't see anything there. "What's following us?"

She looked back and the man was gone. Her stomach turned and there was that familiar shiver down her spine.

"Hello?" she called timidly into the emptiness that surrounded her on all sides.

Her heart was thudding in her chest now. What little confidence she had in her safety was swiftly dwindling, and now more than ever she just wanted to curl up in the Doctor's arms. Where was he?

He's gone, said the vicious voice in the back of her head. Gone, just like all the other times.

"But he always comes back," Amy murmured, not allowing herself to lose faith completely. I just need to figure out what's going on here.

She continued down the corridor, heading for the picture on the wall at the end, which looked somewhat like a map...
