A/N - Now for a quick Meanwhile in the TARDIS just to show how long times progressed between Episode Two and Episode Three! Not much to this one, really, but a wee review'd be appreciated :)

It had been four days since Callum's birthday, and every night since he'd been in the TARDIS, he'd not been able to sleep until he'd had hot chocolate and went for a walk.

He'd found some pretty interesting rooms in the TARDIS, including a swimming pool, a massive library, several garden-like rooms, a room full of musical instruments that started playing themselves and charging towards him until he left and closed the door behind him, and he'd even caught a glimpse at a room that appeared to be another console room, before the doors slid shut and refused to open.

Tonight, he walked his usual route away from the kitchen, past Amy's room, up a set of stairs, past the Doctor's study, two lefts and a right, past the music room and then up another set of stairs. He was going to the library, to see if reading would help get him to sleep.

The doors slid open and he stepped into the warm room. The fireplace was always burning away when he came in and he wondered if it ever stopped.

He put his mug on one of the wooden tables next to a large, comfy-looking leather chair, and began looking along the shelves. There was a small flight of stairs behind one of the bookcases that lead to another level of bookcases, and above that there was another three levels, with doors leading off to other annexes and sections. Callum had tried going up to the top the night before, but the stairs going to the top floor had broken, and it was too late at night to consider repairing them.

All the books on the first level appeared to be from Earth, and Callum even saw a few he recognised. A collection of battered Harry Potters, and what appeared to be a series of prequel books called The Marauders, which Callum had been drawn to immediately. There were also copies of To Kill A Mockingbird, the Da Vinci Code, A Christmas Carol, every single Agatha Christie book, including one called Death in the Sky which someone had written the words 'Copyright Donna Noble' on in red pen. There was a book on The Life and Death of Vincent van Gogh, a selection of Shakespeare plays – in which the Doctor had pointed out which quotations he had given to the bard, a book of limericks and a TARDIS manual that Amy had tried to write – noting that the Doctor had threw the original into a supernova. There were also several blank diaries, with covers that looked like the TARDIS. One of them had the Doctor's handwriting on it, reading: "To River, when the time comes." Another one, titled 1000 Year Diary had been written in by what seemed to be eleven different people. Callum reasoned that being 907, the Doctor's handwriting had probably changed a lot.

Callum, letting his curiosity run away with him, couldn't resist taking a look, and flicked through the pages. The pages seemed to have been colour-co-ordinated by the Doctor. And there was 11 strikes of colour. Looking at the first section, Callum read something that looked like it said "Met Marco Polo", but the rest of the page seemed to have faded. Skipping to the next section, Callum noted that a lot of pages were missing information. The third section onwards were all fine, and Callum flicked through an entry on meeting Sarah Jane Smith, then an entry about a boy called Adric dying. Another entry mentioned some sort of Time War, and then, under the ninth streak of colour, a lot of blank pages, then a single word: Rose. After that, there came more about travelling with Rose, then Martha, and Donna. The final entry had been scrawled in quickly and the very last sentence read: "She'll never remember Rory."

Callum slid the book back in, suddenly feeling rather annoyed at himself for being so nosy. He took a blank book off of the shelf and found a fancy fountain pen on a desk. He wrote his name on the first page, and then began to record the events of the past five days.

Since Hollywood, they'd been to Disneyland Venus, had a run-in with some angry Cat Priests on Monisiphus Six, got lost in a city made entirely of glass, and went to a beach on Calypsos Four, where they'd been kicked out for not obeying the rules - "But I could swear it wasn't a nudist beach the last time I was here!" the Doctor had insisted.

Callum sat writing into the book for about an hour, and got so caught up in writing that he never noticed the doors slide open.

"Hello!" the Doctor smiled, cheerfully, stepping into the library, eating what seemed to be a bright blue apple. He had taken off his tweed jacket and had rolled up the sleeves of his shirt. "Trouble sleeping?"

"Hiya," Callum smiled, then yawned loudly. "Aye, I just can't seem to drift off. It's like there's something stuck in the back of my head that won't go away."

"Oh, I know how that feels! Don't worry, it'll pass," the Doctor replied, taking a bite out of the blue apple. "What are you reading?" he asked, leaning over to take a look.

"I found an empty book, so I'm writing a sort of journal," Callum explained. The Doctor raised his eyebrows and nodded his approval. "But Doctor, how do you get that feeling away?"

"Depends really, in my case: probably never," the Doctor answered, a little more sombrely, pulling a face.

"Oh... never?"

"Well, Callum, you're still young. You've got the rest of your life to work it out!" the Doctor smiled. "Now, I think it's time you got to bed! I've got an amazing idea of where to go tomorrow!"

"Really? Where were you thinking?" Callum asked, sliding the book back on the shelf.

"Oh, you'll find out soon enough!" the Doctor smiled, patting Callum's shoulder as they left the library, the doors sliding shut behind them.
