Hullo there again! Yes, four reviews! That's the best I've ever had for a story on here! (i know, pathetic). So, here's the story: hynswtypie and sweetgirl23 had a neat idea with Rose inhabiting Amy (actually, that's very creative, I might use that later on...), but the answer is indeed the Master! I think the laughing gave it away, eh? Yeah. So, much much much thanks to The New Number 2 (again ;) love ya), hynswtypie and sweetgirl23. You guys are the bestest! And so, I dedicate this chapter to yous. In another case, hynswtypie was the first to get it right, but The New Number 2 was the first to "guess" or review. So if you guys could give me a name (first and last please) I will most happily put it into the story for you! So, I may continue:

4. "I Know That Laugh"

Amy felt her immediate senses - hearing, smelling, seeing, tasting and touching - fade away like water down a drain. She tried to move her arms and legs, but it felt like her nerves were no longer attached to her brain, and she could not feel a thing moving. Terror rose up in Amy's chest, then it all... faded away. The feeling, or rather, the non-feeling. Amy had control over her body again. But that overwhelming desire to rip Martha Smith apart - now the feeling was telling her to tear apart Jack too - was gaining truth. She wanted to destory them, in the mosy evilest way. Out of the corner of her eyes, Amy Pond saw Mickey Smith take out the gun that was carefully concealed beneath his jacket. "Wait, stop!" she shouted. "I'm fine, it's gone!"

Mickey relaxed, but everyone else was still on edge. "I know that laugh," Martha whispered increduously. Jack nodded, his face pale, as though someone had just painted it dead white. Mr. and Mrs. Jones looked at each other fearfully, then Mrs. Jones burst into tears. "No, no, no..."

"What is it?" Amy demanded, her fear showing in her own face. But only Jack paid any attention to her, looking up to see what she asked. "What is this thing that took control of me?"

"It's not a thing," Jack answered gravely. "It's a person. A Time Lord, to be completely exact. We briefly told you about him. His name is the Master, and he is the polar oppisite of the Doctor. His only mission is to 'master' the universe, and turn it into his own playground," Jack looked at her, but only for a moment, then looked away, like it was painful to even see her terrified face. "Sorry," he appologized. "It's hard to look at the face that once held the Master. Even for a moment."

Amy was not sure weither Jack meant look at her face for a moment, or if the Master inhabited her for a moment. She had seen what the Doctor could do, amazing, horrifying things, and that fact that there was another Time Lord out there, an evil Time Lord, chilled her. And the fact that it was inhabiting her terrified her. Amy turned back towards Jack, willing him to look at her, steadily pushing down the feeling to rip him to shreds. The time had not come yet, something deep within her purred. The time will come soon when you will rise to my conquest and help me restore my brilliant power.

No, no it couldn't be true. No, she would not help him. She refused. But the will to kill was only stronger then.

Suddenly, Amy felt someone tackling her. She screamed, and tried to push them away, but the person was already holding her down. "GET. OFF!" she yelled, and pushed with all her might... and sent the person atop her, Mickey Smith, sprawling across the room. Amy looked at her hands, unable to believe the events that had just transpired. The normal, human Amy wasn't that strong. She could barely escape a arm wrestling match with Rory unscathed!

Then, strong arms grabbed her from behind. This time, she did not dare struggle. She stayed perfectly still, and let the strong arms that belonged to Jack Harkness carry her downstairs, to the cellar.

"What are we going to do?" Mickey Smith demanded, his face as hard as stone. "We can't let Jack fight her down there forever. What if she kills him? Kills him permanently? God knows if she can do that now. Scratch that, no one knows what she can do period!" he swallowed hard. "Martha, we have to do something. We have to find the Doctor, the proper Doctor, and have him help us out."

"Whatya mean, the 'proper Doctor'?" Martha asked. "Is there a different between the proper Doctor and the Doctor out there?" she jabbed a finger towards the windowpaine.

Mickey nodded. "Yeah. You saw the way that wuss ran out today. The old Doctor, the tenth Doctor, or whatever the hell he's called, can help us. We just need to know how to find him and get to him. Go back in time, yeah? Find him and drag him to the future."

"That's impossible," Martha shook her head. "The Doctor has told me, multiple times before, it's basically impossible." she looked away from Mickey. Her parents had gone upstairs, trying to console her mum, who was still freaking. "We need the Doctor, and if this 'wuss' Doctor is all we got, then we might as well use him."

"One prob," Mickey inturrupted. "We don't know where the Doctor is."

The Doctor and Mickey Smith had a common problem; neither knew where he was. The Doctor knew he was sitting on a bench, the sun starting to set in the distance, with houses that all looked the same surrounding him. How could he remember which one was the Jones house? The Time Lord rubbed his face in his hands and wondered if life would get any easier from this point on.

S'Oh well. He got up and began to wonder back down where he came, slowly. The slow path, the Doctor thought whimsically. I hate the slow path, and I'm taking it now.

What trouble had they gotten up to today, The Doctor wondered.

Probley not the end of the world.

Don't say that, Doctor! Coz whenever you say that, the world really does end! Haha, I know it's short, sorry, but it's all I've got for this chapter. In the next chapter, as soon as I get one review, then I will most happily write the chapter about Rory that night. Yes, I decided to bring Rory in. The next chapter will be half Rory at night, half the Doctor at the Jones house. I hope you enjoyed it! Love to y'all!
