"So what are we doing here?" The Doctor asked, running up to the TARDIS console. Amy, Rory and River were close behind him. As they gathered round the console, they threw furtive glances at Aderyn, who was sat away from them all.

"we've been recruited. Something to do with space 1969, and a man called Canton Everett Delaware III." River said. She moved around the console so she could keep both the Doctor and Aderyn in sight.

"Recruited by who?"

"Someone who trusts you more than anybody else in the universe."

"And who is that?"

River smiled sadly at him "spoilers."

The Doctor began walking around the console, flicking switches and pulling levers, talking in that over confident way he had.

"1969, that's an easy one. Funny how some years are easy. Now, 1482, full of glitches. Now then, Canton Everett Delaware III, that was his name, yeah?"

Amy sighed sadly and walked away. There was something very wrong and she couldn't put her finger on it. Of course being invited to watch the Doctor die had been troubling, deeply troubling, but the odd appearance of Aderyn only troubled her more. Every now and then Aderyn would give them odd looks as if she didn't know them and was sizing them up.

She found her way under the console and sat quietly, closing her eyes and listening to the Doctor above her walk around and talk continuously.

"How many of those can there be? well, I suppose, three."

As the Doctor leapt around the console he noticed Amy walk away. He also couldn't help but spot River soon follow her.

"Rory, is everybody cross with me for some reason?"

Rory clapped him on the shoulder "I'll find out."

The Doctor watched him walk away, before turning his concerned attention towards Aderyn. He watched her for a few minutes before resuming his bizarre dance around the console. He didn't notice Aderyn walking over to Amy and River.

"Explain it again." Amy said, her voice shaking.

"The Doctor we saw on the beach was a future version, 200 years older than the one up there." River explained.

"But all that'll still happen? He'll still die?"

"We're all going to do that at some point." Aderyn said, making them all jump. Rory glared at her, distrustfully. "We're not all going to arrange our own wake and invite ourselves."

Amy stood up "We have to tell him" She said defiantly.

"We've told him all we can. We can't even tell him that we've seen his future self." River put out a hand to stop Amy moving towards the stairs.

"He'd want to know."

"Would he? would anyone? He's interacted with his own past. It could rip a hole in the universe."

Amy rounded on Aderyn "he's done it before."

Rory put a comforting hand on her shoulder "In fairness the universe did blow up."

Realising she was getting nowhere, Amy, once again, rounded on Aderyn "What do you want anyway?"

"Hey don't snap at me just because your precious Doctor does something as natural as dying for the first time." She glared at Amy.

"Why weren't you there?" Amy said "You were meant to be there."

"Because I knew what was going to happen. I've already watched it once before and I refused to do it again," Aderyn snapped. She sighed, it wasn't their fault so she shouldn't be angry with them. "Look, I'm just trying to figure out what I'm doing here. I'm not meant to be here, but here I am all the same. I need to know what I have to do." she looked between the three of them

"You were invited, weren't you? Like the rest of us." Rory said.

"Yes and no. It's very complicated and I'm not actually allowed to tell you. But you all know him, I don't know how you know him, or how well you know him, but I need to change the future. I had no instructions other then that...well nothing I can tell you anyway. I'm going to need help."

"You have no idea who we are do you?" River said.

Aderyn frowned "Am I meant to?"
