I know it's not the best but I had to write it and hey I thought I would put it up. Hopefully it will all make sense by the end but hey! in my head anything goes!

A small visit to earth, no biggie and no life threatening danger made a change. Finally, a boring day. What the Doctor didn't realise was just how interesting it was about to get.

The Doctor unlocked the TARDIS and waltzed in, humming quietly to himself, until he heard a noise. "Amy? Is that you?" he called out into the open space. "Or is it just you messing about." He smiled and stroked the centre console, only briefly in case Amy was around. He didn't want her laughing at him like Rose and Sarah-Jane. He smiled to himself, remembering trying to save the world with them laughing in the background. He walked around the console then to the monitor. Fiddling with the console he heard another noise. "What have you been eating today?" Chuckling to himself as he spoke to his time machine he turned away from the console and straight into something. He looked around to make sure no one had seen him walk into something in the machine he had spent hundreds of years flying. Satisfied nobody was there with him he looked down to see what he had run into. "Oh." The Doctor backed away surprised.

"Don't worry you haven't lost it and started walking into stuff that has been in here for ages."

"You can't be in here though. It's not possible."

"Why wouldn't it be possible? Your time machine, lets face it, its made of wood. Other people have got in before haven't they?"

"Not without being…" He remembered Donna Noble's surprise appearance in his space-time machine. "…Let in. Ok that's not true but…?"

"Who's this?" Amy came bursting into the TARDIS, personality first.

"Amy," the Doctor attempted to explain, "this is… who are you?"

"Just call me Lucy."

"Ok call me Lucy, this is Amy."

"How did she get in here?" Amy asked, incredulously.

"I opened the door and here I am," Lucy replied simply.

"It was locked," the Doctor insisted, "I checked it."

Lucy shrugged. "That's how she just got in here." Amy glared at her.

The Doctor patted the console behind him nervously. "Right well… erm… You'd better be going Lucy. It's late out."

"I know the time, I'm not a child. I'm probably older than you." Amy and the Doctor exchanged a smile before looking back at the 'possibly-could-pass-for-eighteen year old'.

"Riiight." The Doctor placed a hand between her shoulder blades before attempting to manhandle her out of the control room and back into the little park they had landed in.

"Doctor," she began to plead just before being pushed out.

"How do you know me?" He looked into her grey eyes, scrabbling for answers. They held none.

"Just let me have one more trip," she continued, "Just one."

It clicked in the Doctors head then. She must know him in the future. One last trip to keep her from nagging couldn't hurt he supposed, could it?

I know not the best. Criticism is welcomed.
