"Well done, everyone," the Doctor said approvingly. "Slight judder as we landed, but never mind, practice makes perfect."

"Doctor," Rory said, "we're in Disneyland."

"Yes, we do appear to be," the Doctor said. "It's moved here."

They looked at it with curiousity.

"Space Mountain's changed a bit," Mickey said.

"Minnie Mouse has changed a bit," Amy said.

"Kindly direct your attention to this map," the Doctor called, and they all turned around. "Other attractions include...a water park, but it's exclusively for fish people. Biscuit Land...not sure how that works. David Beckham land?"

"I'll choose!" Amy said, and pressed her face close to the map. She pointed her finger. "This one. Land of horror. The highest and most dangerous rollercoasters, it says here. And 'the most terrifying attractions in the known and unknown universe.'"

"Are you sure?" Rory asked. "I mean..."

"What?"

"I'm not a fan of..."

"You're scared," Amy said cheerfully.

"No, no, not scared, I just don't fancy the idea of, you know, being scared for fun."

"Alright, whatever."

"I'm up for horror land," Mickey said.

"I think I'd prefer..." Martha glanced at the map. "This one. A nice swimming pool and restaurant."

"Yes," Rory said, "that sounds much better. Why don't you come with us, Doctor...hey, Doctor?"

The Doctor was glancing skywards, surprise on his face. And concern.

"Doctor?" Amy said.

"Yes. I mean, you four go ahead and have fun, I'll see how my fish custard ice cream measures up, and I'll meet you all back here in a few hours. Feel free to let yourselves into the TARDIS." He waved at them. "I'm sure at least one of you has a key. Bye bye!"

And he fled.

The four companions watched him go with curiousity.

"Shall we treat this as a holiday?" Rory finally said.

"I think so," Amy said.

"Okay," Martha said, still looking out at the Doctor. "You're sure he's not going to end up in trouble?"

"Oh yeah...he will," Amy said. "But he'll be fine, he'd tell us if he wanted us along, right?"

"I suppose," Martha said. "What's he like, then, this new one?"

"Well," Amy said, "we don't really know what the old one was like."

"He was wonderful," Martha said sadly, "and I sort of miss him."

Amy paused to consider this, but couldn't come up with anything to say.

"Shall we get going?" Mickey asked.

"Yeah, let's," Martha said. "Who's going where and who with?"

"I'm off to horror land," Amy said.

"I'll go with you," Mickey said. He shot a quick questioning glance at Rory, and Rory shot a quick nod back.

"I'll go to the pool, then," Martha said. "Just swim around for a bit."

"Pity I'm gonna miss that," Mickey said.

"I'm going to the pool too," Rory said. "Not to swim," he added hastily, with a look at Mickey.

The four of them all stood around, somewhat awkward.

"Right! See you," Martha said, and gave Mickey a quick peck on the cheek.

"See you, Mr Pond," Amy said to Rory, and gave him what could be best described as a subtle snog. "Gotta go!"

The two pairs headed off in opposite directions.

And someone somewhere watched them.

Amy and Mickey headed towards the rollercoasters.

"So, when'd you meet the Doctor?" Amy asked.

"A long time ago. He was a different one to Martha's Doctor. Looks like we all got a different one."

Amy nodded thoughtfully.

"I never knew there was more than one." She said it with a hint of nervousness, as secrets were about to come out. "I always thought there was just my one."

"He never explained it to you?"

"No."

"He never explained it to anyone. Not even Rose."

"Who's Rose?"

"Oh, someone else who traveled with him."

"There's been a lot of us," Amy said. She sounded more glum than jealous.

"Yeah, well, you're doing...good. You're doing good. I mean, you're married to the man you're traveling with."

"That's true, but..."

"Do you love him?"

"What was that?"

"Do you love Rory?"

"No," she said sarcastically, "I'm just settling for him while I wait for Robert Pattinson to become available."

"Alright, alright."

A pause.

"So...you said I was doing good."

"Yeah."

"What does that even mean?"

"Well, um, people don't always have such fun traveling with the Doctor," Mickey said. "I came out of it and now I've got a wife and I travel the world and I'm better, a better man. But it wasn't fun. Not all the time. Hardly ever, for me."

Amy stared at him like he'd confessed to a crime.

"Why?"

"Because he took this girl who meant so much to me."

"Rose?" Amy said.

"Yeah."

The thought of riding rollercoasters and experiencing pure horror had been temporarily forgotten. They sat down on a bench.

"When you say took her..."

"She was in love with him. She never forgot him. Even when we were in a completely different world she never forgot him. And when I was with them in the TARDIS I was a third wheel, ignored pretty much. And laughed at."

"He doesn't sound nice, your Doctor," Amy said.

"He didn't have to be, he saved the world."

Amy thought that was strangely profound. She didn't say so though. As she often did, she filed it away to be agonized over and changed the subject to something more cheerful.

"Shall we go then? That looks like it over there. Where that massive tower is."

Both stood and looked at the tower. They were about to walk into a place that promised horrors, but that tower threatened horrors. It looked so out of place. And the windows looked like a pair of red, angry eyes.

"Is that one of the rides?" Mickey asked.

"I dunno. Let's go see."

She took his hand- this was something that Amy just did with everyone- and they ran towards it.

Rory tried very hard not to look at Martha in her bikini. Not that he fancied her at all, but she might see him looking and think he was staring and who knew what unpleasant things might happen. Martha stashed her clothes (it had to be some kind of army uniform, Rory thought) in one of the many lockers and turned to him.

"There's a place over there where you can buy swimwear," she said. "Well, actually, they sort of design it for you on the spot, with some sort of machine. It's quite cool."

Rory nodded.

"You not coming in the water?"

"No, no, I'm okay."

Martha slid into the pool and swam up and down before returning to the side. "You look like you have something on your mind."

Rory had been staring at the huge rollercoasters on the horizon, and hadn't really heard. "What?"

"You look like you have something on your mind."

"Oh. Yeah. Loads of things."

"Like what?" When he didn't answer she grinned and said, "You can trust me. I'm a doctor."

"A real one?" Rory asked, startled out of his thoughts for a second.

"Yeah, a real one. Passed my exams and everything. Unlike some other Doctors."

"I always wanted to be a doctor. I'm just a nurse."

Martha climbed out of the pool and sat on the deckchair with him. "Well, every nurse I know has a hard time. Everyone always takes them for granted, and makes them run around like crazy trying to help everybody, and has them do all the nasty jobs..."

Rory paused. "That sounds about right."

"And they never get much credit."

"That's about right too."

There was a brief silence and then Rory said, "The Doctor just went off without us. Did he used to do that with you?"

"Sometimes."

Somewhere above them there was the sudden whirr of a camera. But Rory spoke over it.

"I don't know...I think...I think Amy could do this forever. Just hopping about from world to world. But me, I don't know. We got married, we went on our honeymoon, we stopped off in New York to pick a new wardrobe for Amy and now we're here, and I just want some quiet. I think. Maybe. But I don't want to go back and have a normal life either. Everything's just gotten so confused."

"So you got married, like...a few weeks ago?" Martha said.

"It feels like a few days ago."

"Uh-huh."

"And so happened before that, it's hard to explain. I died. And then I came back and I guarded Amy for two thousand years and I don't know, we're here now and both of us have at least two sets of memories and it's all very..."

"Wait, what? You died?"

"Yeah. And we've never really sat down and talked about it, not properly, never talked about the future..."

"Wait...you died? How did you come back to life? Because I know this one man who...does that a lot."

"I don't know, I just did. The Doctor can explain it better than I can. But anyway, that's what's on my mind. All that crazy stuff. And you're really good to talk to, Martha, I just wish I was talking to Amy instead...what is it?"

Martha was looking at the sky.

"That's a camera," she said. "That's a camera I've heard a lot about."

Rory looked. "Is that bad?"

"I need to find my trousers!"

"What?"

"Rory! Help me find my trousers!"

Amy and Mickey stood inside the Land Of Horror, neither feeling particularly horrified.

"There's a very large amount of clowns here," Amy said.

"Guess a lot of people are scared of clowns."

"Are you?"

"Not really. You meet scarier things than clowns in the TARDIS."

Amy wondered what he meant- the various monsters or the Doctor?- but she tried not to dwell on it. "Where shall we go first?"

Mickey glanced around. "Well, there's pretty long queues for everything." He headed for one of the many holographic maps. "The world's highest roller coaster. The world's most haunted haunted house. The world's most evil Italian restaurant..."

"Or the tower," Amy said.

They both looked at the tower.

It was indeed a ride. There was a line of people lined up for it, including children, all of whom looked perfectly cheery. Above them floated a few cameras, and it all looked perfectly safe and normal.

"Shall we get in line?" Amy asked.

"Yeah, alright," Mickey said.

They looked at each other almost as if they were daring the other one to back down first, and joined the queue.

Martha had pulled open all the lockers and located her trousers. From one of the pockets she pulled a small device, and then she jumped onto one of the chairs.

"What are you doing?" Rory asked.

"It could be nothing," Martha said, "but it's never nothing around here..."

Her device beeped, and the camera fell down and she caught it. She climbed off the chair.

"Yeah," she said, "it's not nothing."

"What is it?"

"That camera," she said, pointing to it, "is a telepathy camera. It records you and it records what's in your head. They're illegal almost everywhere."

"And they're illegal here?"

"Yeah, I would have thought so. This friend of mine, Jack, he had this incident involving one of them...and these three women...and these five men."

"What?"

"The point is is that it shouldn't be here. And remember how the Doctor just looked up and ran off? He might have seen one too. Look at the logo on it, it's distinctive, it looks like a tower with eyes."

"Why didn't he tell us what he was doing?"

"He's just like that. Always like that. I suppose."

"Well," Rory said, when she didn't elaborate, "what should we do?"

"Well, I'm going to get out this bikini-"

"You're-"

"And go to find the Doctor."

It took only a few minutes for Amy and Mickey to reach the end of the queue. When they stepped in through the door, the tower was quiet. Deadly quiet. Far quieter than a simple rollercoaster ride ought to be. And there wasn't another person in sight.

A single cart was on a track.

"After you," Mickey said.

Amy stepped in, and Mickey after her.

"Wait," he said, "there's no seatbelts-"

The cart took off at the speed of sound. Before Amy knew it, they were plummeting and looping and screaming and screaming-

-and then they stopped.

"What, was that the ride?" she gasped. And then she saw it.

The track had come to an end, but behind them there was a mangled body on the track. It was a man, arms spread out, face down. Amy climbed from the cart, terror in her veins.

"Mickey!" she shouted. "Help me!"

Mickey was in a daze, so it seemed, but he climbed out too. Amy reached the body and turned it over.

"No," she whispered. "No, no, no, no!"

It was Rory. Or it looked like him. And on his barely visible face was an expression of sheer horror.

Mickey stared down in bewilderment.

"No!" Amy screamed. "No, not again! No! No! No!" She actually reached out to the body and tried to pull it from the track. "No!"

Mickey came back to his senses, picked her up and pulled her away.

"Amy! Amy, look at me, think about it. Rory's with Martha. How could he be here?"

"It looks like him!" Tears were running down her face.

"Amy, it's not him, it's got to be an illusion. The ride promises pure horror, right? What could be more horrifying than seeing your loved ones dead? It isn't him."

Amy broke free of his grip and stared down at the body. And stared for a long time.

"It looks like him," she said again. She was still crying.

"It's not him. Let's get out of here, Amy."

Amy very slowly moved away from the corpse and fell into step with Mickey, who had already started walking.

"There must be an exit," he said, but there was fear in his voice too. And then he stopped dead.

"Oh god no," he said.

"Mickey!" Amy panicked. "What is it?" But then she saw it too. Another corpse. This one was a woman, a blonde woman, her blood still seeping into the ground...

"Rose," Mickey said.

Amy stared down at this girl she didn't know, and then Mickey let out another scream.

"Martha!"

Because she was there too.

"Mickey," Amy said, terrified and shaking, "how do you know it's not them?"

"Because Rose can't be here!" Mickey screamed. "She's somewhere else, I left her behind! Let's run, okay? Run!"

So they ran.

But the place was a maze of caves and it was dark, and getting darker, and someone somewhere was screaming. And when they realised they could run no more and collapsed on the cold ground, a voice echoed out.

"Mickey the idiot," it said.

"Who's that?" Amy snapped.

"Mickey the idiot, just look at you," the voice continued. "Lost in a blooming cave! Why you came with me I don't know. You never saved the world, you never saved anyone or anything."

"Who is it?" Amy screeched into Mickey's ear.

"My Doctor," Mickey answered.

"But he sounds like he's from the North!"

"Lots of planets have a north. Apparently."

"Rose is dead," the voice said. "Rose is dead, your wife's dead, they're all dead, Mickey, and it's your fault."

Mickey was rooted to the spot and silent. Amy pulled at his clothes.

"Come on! We have to find a way out."

"Yeah..." Mickey said dizzily, "yeah..."

They ran again. This time the cave widened out, and there was light...

...and a final corpse.

"Oh no," Mickey said.

Amy was silent.

It was the Doctor, Amy's Doctor, and he was lying on the ground with his eyes closed. Beside him was the sonic screwdriver, but someone or something had stepped on it, and its wires were exposed and the light was flickering green and red.

"You know it can't be him," Mickey said.

"It could," Amy whispered. And she walked towards him.

"Amy, don't," Mickey said. "It's trying to trick us. That voice back here, all the bodies, they're trying to scare us, that's all..."

"It could be him," Amy said again. The lights were going out.

"Amy! Come back! I can't see you," Mickey called out in a panic. The lights dimmed and dimmed, Amy knelt by the body-

-and something grabbed her shoulders.

"AAAAAAAAAAAAAH!"

"Amy!" Mickey shouted. "Amy!" He charged into the blackness, fists raised, hit something in the face-

-fell over the still-kneeling Amy, and the lights came back on.

The Doctor was standing there, next to his own corpse. He'd raised the sonic screwdriver and turned the lights on again. With his other hand he was rubbing his face.

"Doctor," Amy said in relief. She crushed him in a hug, and kissed his cheek.

"Oi! Watch it there, Mrs Pond. I'm fine, please don't squash me! I've just been whacked in the noggin after all." He gently untangled himself from her arms. "Were you worried about this?" He poked the corpse with his toe, and pointed the screwdriver at it. The image of the Doctor faded, to be replaced with a robotic human form. It was a metal dummy, so it appeared, silver with a blank face.

"So they are all images," Amy said. "There are, right? Tell me they are."

"They are."

"Rory's okay?"

"Yes, I imagine so. He's with Martha? She'll look after him."

Mickey sighed in relief and looked around.

"I'm not complaining, Doctor, but how did you get here?"

"Walked in."

"Really?" Amy said. "We had to queue."

"Yes, I found an even more uncomfortable way. Remember when I left you four, not too long ago? I'd spotted something a bit out of the ordinary. One of these." He pulled a small metal camera-like thing from his pocket. "This is a very complicated, very clever, very illegal recording device. They're telepathic, they can read thoughts, and I wondered what one would be doing on this planet."

"I've never seen anything like that before," Mickey said.

"No, no, it was Jack who told me about them. Apparently he got into a bit of trouble involving one of them, two men, four ladies, an Auton and a sentient yacht. Anyway, I followed this one until it went to the tower and through a door. I went through the door and was hit very hard on the head. I woke up here in a very dungeon-like place, soniced the lock, went up some stairs, heard the pair of you screaming and here we are!"

"...Right." Mickey said. "Right, right, that's good."

There was silence...until, far off in the distance, there was another scream.

"I don't like that," Amy said. "Doctor, what should we do?"

The Doctor turned to Mickey. "Okay, Mickey Smith, any ideas?"

"You're asking me?"

"I am."

"Oh, um, well...we need to find out who's screaming. And save them."

"Couldn't have put it better myself! Let's go."

He took both Amy's hand and Mickey's and they marched into the dark.
