Rory looked round at the door. He had felt the tremors as the Dalek had exploded.

"Oswin, what was that?" He asked tentatively "That sounded close." He pushed open the door and walked back into the chamber he had run from. The Daleks that had been there had been reduced to smoking hunks of metal. "What happened? Who killed all the Daleks?" He took a step backwards when he heard approaching footsteps. But breathed a sigh of relief when he heard the Doctor say "Who do you think?" He emerged through wisps of smoke, carrying Amy. Aderyn made less of an entrance. She walked in behind the Doctor, brushing dust from her jumper. The Doctor carried Amy through to the room Rory had been in, finding a safe place to place her gently on the floor.

"What's going on?" Rory asked.

"Where do I start?" Aderyn said with false cheer "We've been chased by Dalek skeletons and had another Dalek try to blow us. Oh and your wife is slowly being turned into a Dalek puppet."

"You probably should have started with the last on," Rory said calmly. "So what's going to happen to her?"

"Well, the process has already started. She is loosing short term memory and seeing things a bit differently." Aderyn said, looking down at Amy.

"Will sleeping slow the process?" Rory asked quietly.

"You'd better hope so because pretty soon she's going to try and kill you." Oswin said.

On the floor, Amy began to stir. The Doctor and Rory knelt next to her.

"Amy? Can you hear me?" The Doctor asked.

Amy's eyes opened.

"Amy, do you remember me?" Rory asked. His answer came as a slap to the face. "Yep, same old Amy." Rory muttered.

"Do you know how you make someone into a Dalek?" Oswin asked. Aderyn leant against a wall and crossed her arms.

"No. But I have a feeling you're going to tell us." Aderyn said. She watched the Doctor and Rory fussing over Amy.

"Subtract love, add anger. Doesn't she seem a bit too angry to you?"

Aderyn chuckled "Well, someone's never met a Scot before. But what about you? How are you still okay?"

Aderyn could almost hear the nonchalant shrug as Oswin replied "I mentioned the genius thing, yeah? Shielded in here."

"That's clever of you," Aderyn began to pace the room, looking closely at everything. She was very aware that she was being watched, not just by Oswin, but by the Doctor, Amy and Rory as well. "Now, this place. The Daleks said it was fully automated. Look at it. It's a wreck."

"Well, I've had nearly a year to mess with them, and not a lot else to do." Oswin said smugly.

"I really don't understand." Aderyn started.

Amy snorted "Wow, that really is a surprise. Usually you're as bad as the Doctor. Always seem to know and understand everything."

"Oh, shush." Aderyn snapped.

"Did you just shush me?" Amy forced herself into a sitting position. She tried to stand but the Doctor pushed her back down.

"Yes I did. Now shush," Aderyn stared at her and Amy fell silent. Years of putting up with River's raised eyebrows, hard stares and motherly tones had rubbed off on Aderyn. "A junior entertainment manager hiding out in a wrecked ship, hacking the security systems of the most advanced warrior race the universe has ever seen. But you know what really gets me?" Aderyn paced a small circle around the room, glaring at Amy as she went passed as though daring her to interrupt "The souffles. Where would you get the milk for the souffles? Seriously. Is no one else wondering about that?"

"No. Frankly, no. Twice." Rory snapped.

Aderyn frowned. Maybe it was nothing. Maybe it didn't matter.

"Doctor, I've been looking you up. You're all over the database. Why do the Daleks call you the Predator? And who is the Little Bird with the broken wing?" Oswin asked slowly.

"I'm not the Predator. As for the Little Bird, that's Aderyn." The Doctor said thoughtfully.

"You?" Oswin laughed "The Daleks are scared of you?"

"Let's just say I make one hell of a first impression." Aderyn smiled. She stopped pacing and stuffed her hands into her pockets "So, Doctor. Do you have a plan?"

"Yes," The Doctor replied. The look on Aderyn's face was enough to let him know that she was in the mood to fire off some sarcastic comments and tear apart any plan he had. She was clearly incredibly fed up. "I'm a man with a plan."

"That's all he is." Rory muttered.

"There's a nose joke going if someone wants to pick that one off." Amy said, glaring at Rory.

"Nah, I'll leave the nose jokes to you. I prefer to make the chin jokes." Aderyn replied with a smirk.

The Doctor chose to ignore Aderyn's comments. It was always best not to respond when she was in this sort of mood.

"In no particular order," He said triumphantly "We need to neutralise all the Daleks in this Asylum, rescue Oswin from the wreckage, escape from this planet and fix Amy and Rory's marriage."

"Okay, I'm counting three lost causes. Anyone else?" Amy snapped.

"How do we even start to do anything like that?" Aderyn asked.

"Oswin, there's a Dalek ship in orbit." The Doctor said.

"Yes. Got it on the sensors." Oswin confirmed.

"The Asylum has a forcefield. The Daleks upstairs are waiting for me to turn it off. Soon as I do, they'll burn this whole world and us with it. So, Oswin, my question is this. How fast can you drop the forcefield?" The Doctor paced the line Aderyn had abandoned.

"Pretty fast. But why would I?"

"Because this is a teleport. Am I right, Oswin?" Aderyn said, quickly catching up with the Doctor's plan.

"Short range. Internal use only."

"I can boost the power. Once the forcefield is down, I can use it to beam us right off this planet." The Doctor said, looking through the glass panel of the teleport pad at the wires beneath it.

"Your aim with the TARDIS is hit and miss. Why would you be any better with this?" Aderyn scoffed.

The Doctor muttered something about different navigation systems. But Aderyn shook her head at him.

"You said when the forcefield is down, the Daleks will blow us up." Rory commented.

"We'll have to be quick." Aderyn said.

Amy rolled her eyes theatrically "Fine, we'll be quick. But where do we beam to?"

"The only place in range." The Doctor said. Without any further explanation the Doctor lifted a hatch and began to fiddle with the wiring.

"The Dalek ship? You're going to beam us up to the Dalek ship?" Aderyn sighed.

"So this is the kind of escape plan where we only live for about four seconds." Rory said.

"What's wrong with four seconds? You can do loads in four seconds." The Doctor whined.

"I don't have a death wish anymore, Doctor. I want to live longer then four seconds." Aderyn hissed.

"Just trust me," The Doctor said "Oswin, how fast can you drop the forcefield?"

"I can do it from here," Oswin replied slowly "As soon as you come and get me."

"No, just drop the field and come to us." the Doctor said uncertainly.

"There's enough power in that teleport for one go. Why would you wait for me?" Oswin said quickly.

"Why wouldn't I?" The Doctor shrugged.

"No idea. Never met you. Sending you a map so you can come get me." Oswin said. A screen close to the teleport pad flashed into life and Aderyn and the Doctor looked at the screen. Oswin didn't look that far away from them. It shouldn't take them too long to get to her and back.

"But the place is crawling with Daleks." Rory said.

"Yeah, Kind of why I'm anxious to leave. Come up and see me sometime." Oswin said scathingly.

Aderyn moved close to the Doctor "We have to go and get her." She whispered.

"We are not doing anything. I will go and get her and you will stay here," The Doctor handed the control unit to Aderyn "Right, you three can stay here. I will not be long. As soon as the forcefield is down the Daleks will attack. If it gets too explody-wody in here, you go without me, okay?"

"And leave you here to die?" Aderyn snapped.

The Doctor looked at her seriously "Oh, don't worry about me. You're the one beaming up to a Dalek ship to get exterminated."

"Love this plan." Aderyn grumbled as the Doctor pulled the door closed behind him.

"You're not going to let him go alone are you?" Amy said quietly.

Aderyn smiled "Of course not. Rory, Rory, keep her remembering, keep her focused. That'll hold back the conversion."

Without the Doctor there to stop her, Amy stood up "And what do I do?" She said moodily.

"You heard what Oswin said. They're subtracting love. Don't let them." And with that, Aderyn pulled open the door and ran after the Doctor.
