Disclaimer: I don't own Doctor Who. But I'm guessing you knew that. If I did, I wouldn't be on here, would I? :)

I wrote this story quite a while ago, but I've only just posted it now. It was originally a oneshot, but I've decided to expand on it more.

Enjoy!

Rose flushed the loo and pulled a face. They were out of loo roll, again. They'd only picked up a pack two weeks ago. There was only the two of them on board, surely they didn't use that much toilet roll!

Maybe the Doctor was using some of the flimsy paper for some kind of invention that would revolutionize the world as they knew it. It sounded like something he'd do.

Or maybe the Doctor was suffering with a bought of stomach trouble? He was always munching on abnormal, inexplicable cuisine; Rose didn't understand how his insides could hold all that junk. Rose, upon pondering the Doctor's bowel movements, pushed this to the back of her head, tucked away in a dark corner. She really wasn't all that interested in his toilet schedule. Although, now that she had mentioned it, something was odd. She'd never seen him use the loo on the TARDIS, not once.

Back to the matter on hand, Rose thought, rubbing her hands on the patchwork towel and unlocking the wooden door. Back to the Doctor.

"Doctor?" She called, her voice echoing through the vast halls of the spaceship. She listened intently for a reply, but nothing came. She tried again, "Doctor? You there?" She ambled into the control room, her eyes scouring the room for a flash of spiky brown hair, or even the swish of his pinstripes. She ducked under the control, her brow furrowing. It was late, she knew that. She'd been in bed herself when she'd had the urge to use the toilet. But she was sure that the Doctor would still be up.

After combing her way through the numerous libraries and lounges, she dragged her feet along to the kitchen, apprehension descending on her. He hadn't gone out and left her, had he? What if he'd got hurt? What if he'd found someone else?

Calm down, she inwardly scolded, He's probably around here somewhere. The TARDIS is huge, remember? He's probably just..having a nap? Did he even sleep? She knew he had a room of his own, just like she had, but she'd never been in it. How was she to know if he had a bed or not?

Not that she'd ever thought about it. She imagined his room to be enormous, piles of books filling every angle of his shelves. His bed, if he had one, would be a simple model, and when he looked up, he could see the rings of Saturn, the fiery pits of Jupiter, the cool ice asteroids floating through the artificial night sky. His room would be intelligent, romantic, reminiscent and so perfectly him.

Not that she'd ever thought about it, of course.

Instead of lingering on these thoughts, she caught sight of a discarded post-it note pad, situated between a ripe banana and one of Rose's stud earrings. Fumbling around for a pen, which she found next to the Doctor's crossword, she picked up the pad and scribbled down a message.

Doctor,

We're out of loo roll!

Rose

Satisfied with her message, she welded the yellow cube of paper to the fridge. She grinned, picked up a satsuma and retired to her own room.

That morning, Rose awoke slowly by the sound of her door slamming shut. She scrunched up her face in confusion and clambered out of bed.

After she'd given her hair a quick brush and cleansed her face free from last night's eyeliner which had been smeared down her face, she shuffled to the console room. The lights were bright, and the screen was bleeping, but there was no sign of the Doctor.

She wanted to head outside, but seeing as she was in her old hoodie, bedshorts and pink vest, she decided against it. Instead, she trundled back to her room, opting to get dressed for the day ahead.

She entered the bathroom and shed her clothes whilst running the shower. She hummed to herself, stepping into the shower and letting the hot droplets splash onto her skin. She began to sponge her skin and her face, gently wiping away yesterday's traces from her being. She found herself wondering if the Doctor had got her message, and if he'd done anything about it.

Poking her head out of the shower, her eyes fell on a post-it note secured to her toilet lid. She quickly finished her showering duties and padded over to the toilet, her footsteps imprinting damp patches on the tiled floor. She plucked the note from the plastic seat and read.

Rose,

You wanted something?

Like I said, your wish is my command.

The Doctor.

Rose beamed as she fingered the note happily. Sure enough, positioned among her toothbrush and her mascara wand, there was a pack of toilet roll, neatly packaged up and staring at her.

She bounced back into her room, and threw on a pair of jeans and a cheerful blue top. She scrambled around in her draws, her tongue poking from her mouth in concentration.

"Come on, come on," She muttered to herself, her hands pushing through strings of jewellery, rings, and random possessions that she'd lobbed in there when she had decided to finally unpack her stuff. She pulled out her pink post-it note pad, a cheap birthday present off Shareen from eons ago.

Grinning, she scrawled down her reply.

Doctor

Thanks, oh wonderful genie of mine!

Love, Rose

She strolled along the infinite corridor, flicking the post-it note idly in her hand. She glanced into every room, and, at about the tenth room, she spotted the Doctor. She gasped inaudibly and quickened her pace.

"Rose?" His voice drifted from the room. She hid the note behind her back and summoned up her most innocent smile. He poked his head round the door frame, "Everything alright?" Rose nodded, her smile fixed sturdily on her face.

"Yep, yeah. Everything's fine. Just..goin' to get breakfast," She croaked, backing away from him. The Doctor watched her with an amused expression.

"Did you get my note?"

"Oh yeah, and the toilet roll. Thanks," She smiled, still recoiling from him.

"You sure you're alright?" The Doctor asked.

"Yeah, course!" Rose laughed, a little too forcefully. She had made her way to the kitchen and stopped. "Well. This is my stop," She practically shouted. The Doctor was at the other side of the corridor by now.

"OK," He replied, his voice teasing.

She side-stepped into the kitchen and breathed a sigh of relief. She unstuck the post-it note from her fingertips and slid it onto a banana, the one place the Doctor would definitely look.

What do you think? Like it?

If you have any more ideas for the notes, then don't hesitate to tell me! I'd love to have your feedback.

Please review.
