Right... At the moment, this story is just a distraction from the other ones I'm writing, mainly because I'm stuck (as usual) so...

Enjoy!

Disclaimer: I don't own Harry Potter and Doctor Who. Fortunately... 'Cause if I did, Dumbledore would be dead, Voldemort would reign the wizarding world and Rose Tyler would still be in her correct universe.

There are a couple of things you need to know before you start reading: This is right after the Agatha Christie episode. 10th Doctor. 'Cause he's just my favourite.

"No, no, no, no, NO!" The Doctor exclaimed, grabbing a mallet which had been leaning against the console of the TARDIS console, and hit the rather fragile Gallifreyan technology causing a high and clear note to ring out, which echoed throughout the console room. Almost instantly, the Doctor felt a pang of protest echo from the TARDIS to him through their telepathic link, which he decided to ignore and instead flipped a lever on the console (which regulated the speed at which the spaceship was travelling), causing the TARDIS to tabulate and throw the Doctor to his feet.

Again, she was sending him somewhere where he didn't even want to go.

Glancing at Donna he saw she was hanging on the railing for dear life. "Can you even get turbulence in space?!" She exclaimed, arms tightening around the railing as the TARDIS gave another harsh lurch, throwing the Doctor back to the ground, this time next to Donna.

He scrunched up his nose thoughtfully, "You know Donna, that is actually a very good question!" He exclaimed, grabbing onto the railing as well, in order not to be swept to the side as the TARDIS was now tilting slightly. "Theoretically... It's not possible, seeing as there is no wind in space like on earth. Those winds are moving air. There are solar winds given off by stars but they mostly effect energy not physical items-"

"Doctor!" Donna exclaimed, tilting her head at the console which was now releasing sparks, "I think right now, our survival might be a little more important!"

The Doctor glanced at her, then at the console, grinning, "Aha! But what is adventure without life-threatening problems laid out along the way?"

"We're crashing." Donna deadpanned, staring at him as the TARDIS gave another lurch, causing the Doctor to hit his head against the hard floor. As he slowly cracked his eyes open in pain, he gazed up at her, grinning wildly, both sets of teeth shining in the lighting, "All the more fun!"

...

Harry sighed as he slowed to a fast but steady walk and stuck his hands into his pockets. Bowing his head slightly, so that his chin almost touched his chest, he gazed at his baggy trousers which moved every now and then to reveal a pair of worn and ripped red converse shoes which had once been Dudley's. In fact, every single item he was currently wearing, had been at some point, Dudley's, that is everything except his glasses (and a pocket watch that he'd had his whole life, which no one ever seemed to notice) which had been pulled out of the rubbish bin.

Kicking an imaginary pebble out of the way, Harry looked up in frustration only to see that he had ended up at a small park near the Dursley's home. Dudley and his gang had been chasing him again, and it was slowly becoming a sport for them. Piers, one of Dudley's biggest supporters had even started naming it Harry Hunting which only seemed to encourage the others to play along.

This time, though, Harry had managed to shake them of quite early in the chase by crawling under several fences in many backyards.

"Oi Potter!"

Or not.

Turning his head slightly, he spotted Dudley and his gang on the other side of the street, having just climbed over a fence. Dudley even had the red marks on his arm where the fence had dug into him. They all looked rather angry.

Groaning slightly, Harry broke into a jog as he noticed the gang pick up pace, and quickly ducked behind the school building, opposite of the park. Gazing about, he groaned as he saw he had ended up at a dead end. Great. He was dead.

There was an overflowing dumpster standing in the right corner, the opposite corner was filled with rubbish bags filled with awful smelling stuff, other than that, the dead end was empty. So his two choices were, hide in the dumpster (his pride wouldn't allow him to do that, though), or get beaten up by Dudley's friends.

To be fair though, Dudley and his gang were all around the age of eight, there wasn't much they could do... Then again, he was eight too. Biting his lip slightly, he ruffled his hair and leaned against the dirty wall, crossing his feet in the process, hopefully looking like he didn't have a care in the world.

Though before he could come to a proper decision, the gang had arrived at the mouth of the alley, grinning wildly as they realized that this was a dead end and their victim was actually waiting for them.

Then as Dudley started walking forward, a threatening grin gracing his ugly face and his piggy eyes glinting with a sadistic sort of glee, Harry slowly started backing towards the wall at the end of the ally, not quite caring about his pride at the moment. Five boys were advancing on him, three of which played a lot of football, one was orange belt at karate, and the last... Well, Dudley had a considerable weight.

But then, suddenly, before Harry had a chance to even whimper 'help', there was a loud bang, and a sort of shock-wave, and suddenly, he and the other boys were thrown of their feet. Luckily, Harry was thrown into the pile of rubbish bags which acted as a type of cushioning mattress. The other boys weren't as lucky, judging by the cries of pain, and loud thumps as they were thrown to the ground. Blinking slightly, as his eyes fluttered open only to stare at the bright summer sky, he sat up, wincing slightly at the pain at the back of his head.

Reaching back with his hand, he made sure it wasn't either mushy or bleeding. After he had quickly checked everything in his body, to make sure nothing was broken (and put his, thankfully not broken glasses back on his face), he turned his attention back to the scene.

The gang which had been, merely seconds ago advancing on him, was now a pile of humans, moaning in pain. Furrowing his brow, Harry realized that he'd called them humans, not people.

All his thoughts were forgotten, though, when his eyes rested on a wonderfully blue police box standing in the ally, between the gang and Harry. The sides were somewhat scorched and it was slightly smoking. But how had it gotten here? The very laws of physics (which Harry knew by heart) didn't allow this. Standing up, Harry looked around for any hidden cameras, or camera men; this could be some kind of prank, for a reality show or something...

Instinctively though, he somehow knew that this wasn't some kind of prank and that the box held some kind of important meaning. Besides, why would anyone place a 1960s police box here, of all places? And what other box, emanated such a calming air?

Frowning in thought, Harry quickly pushed his glasses up to the bridge of his nose and raised a hand, reaching for the handle...

However, before he could so much as try to push open the door (regardless from what the sign on the door said), it was pulled open from the other side, and a red headed woman and a man with a fire extinguisher stumbled out (nearly into Harry), coughing, smoke following them, as it curled over the roof of the police box and rose into the air.

Before Harry could even get a glimpse inside, the man had slammed the door shut, after shouting "Turn fans ON!" At the police box. Listening carefully, Harry heard an odd sort of whirring sound, not unlike fans, start up inside the box.

Frowning in thought, he turned his attention to the two who had been in the box (what they might have been doing in such a small space was beyond him).

The red headed woman was gently combing down her hair with her hands, looking slightly disorientated as she did so. Her companion, however, a tall man dressed in a pinstriped suit and a brown trench coat over that, had already put the fire extinguisher down and was instead waving an odd metal thing around. It looked like a sort of metal tube, with a light blue light at the top which was emitting a quiet buzzing noise which Harry distinctly recognized, though it was beyond him where he'd heard that before.

Finally the man put his... weapon?... back into his coat pocket and gazed around properly, taking in the situation.

"Er... Doctor?" Said the red-headed woman, "There's a kid staring at us."

Blushing, Harry looked away from her and instead gazed at the TARDIS.

"Sir?" Harry asked, glancing at the man who was inspecting him intently, "Why do you have a 1960s police box? And why-how did it appear here?"

"He sure knows his history," The red head muttered under her breath, causing Harry to shoot her a small glare which she then responded to by sticking out her tongue. The man's face though split into a grin, "Ha! See Donna!" he exclaimed, "Some people are actually interested in knowing stuff!"

The woman - Donna rolled her eyes, "I'm Donna, that's," She jerked her thumb towards the Doctor, "the Doctor."

"I'm Harry," Harry muttered, gazing at the Doctor, "You didn't answer my questions."

The Doctor grinned at him, "Nice to meet you Harry! And no, I didn't answer your questions, now who are those lads over there?"

Harry glanced at the gang quickly, they were all starting to stand up, groaning in pain. Truly, he had already forgotten about them. Dudley had, so far, not moved an inch, though he was demanding food from Piers who was rolling his shoulders.

"I would tell you... But you didn't answer my questions," He said, smiling cheerfully. The Doctor blinked at him, obviously he wasn't used to people defying his questions. Donna though, was chuckling quietly.

"Weeeelll Harry," The Doctor said, kneeling down on on knee to face Harry, "The answers to those questions involve quite a long story and a lot of physics,"

Harry shrugged one shoulder, "I have a lot of time, and a large understanding of physics," He retorted. Sometimes adults were so oblivious to the fact that children could be at times so much smarter than them. The Doctor smiled again.

"Fine then, this is the TARDIS, it stands for time and relative dimension in space-"

"Of course," Harry muttered, breathing in deeply as he turned to the TARDIS, gazing at it with awe, "...relative dimension? That means it's... dimensionally transcendental!" He exclaimed and ran a hand down the side. And his teachers told him that everything he knew about physics wasn't even true. Ha! This was living proof! He was so awed by actually seeing it, that he didn't notice Donna and the Doctor exchange a glance.

"And," The Doctor cleared his throat, "How did you come by this knowledge?" He asked as Harry turned swiftly with a sort of grace not usually found within children. Harry shrugged, thinking back. He'd always known stuff about physics... He'd always understood complex theories, names and formulas almost automatically, as if they were somehow stored within his head, waiting to be unlocked.

"Dunno... I've always known stuff." He glanced at the gang who had by now run off in fright. Only Dudley and Piers remained, and both were backing out of the alley in fright.

"Oi! Freak! We'll catch you later! Wait 'till dad hears about this!" Dudley shouted as he rounded the corner, quickly following Piers who had just sprinted off.

"Did they just call you freak?" Asked Donna in outrage, glaring at the place they had been standing on just moments ago. Harry raised his eyes to meet hers.

"Er... Yeah?" He shrugged, "I don't really mind. At least I'm not an idiot." He muttered darkly, sparing a glance at the Doctor who was staring at him intently. His eyes were a dark brown, and Harry felt a certain familiarity to them. They were dark and held secrets, and looked so, so, old. Ah, right, time-travel. That man could be centuries old.

"How did you know?" Said the Doctor, this time a little more urgently. Harry raised his hands up in defence.

"I dunno!" He exclaimed, his high voice penetrating the silence. The Doctor grabbed Harry by the shoulders, still in his kneeling position, ignoring the hand Donna put on his arm to stop him, and pulled out the metal cylinder again, this time pointing it at Harry who felt his pulse quicken in fright.

"Who are you?" He heard the Doctor mutter under his breath as he waved his 'weapon' over Harry. He then released Harry forcefully, who stumbled back a few paces and hit the TARDIS door painfully with his back.

"Doctor!" Donna exclaimed, running over to Harry, who shied from her touch.

Then suddenly Donna was jerked away, and the Doctor took her place, kneeling down in front of Harry once more.

"Harry, listen! I need you to listen very carefully now." The man took a deep breath and gently took hold of Harry's shoulders. Harry gulped down his fear and stared back into the man's eyes, "Now... Harry, do you trust me?"

Well... that was a little rich. First manhandling him, then asking for trust?

But then, as Harry looked into the Doctor's eyes he noticed a deep, deep emotion there, right under all the sadness and guilt, and that was hope. Harry scrutinized him, eyes narrowing, and finally he nodded. The Doctor seemed to let out a sigh of relief.

"Thank you," he sounded so sincere, Harry knew there was a long story behind this, "Now, I need you to tell me, do you have a pocket watch?"

Harry blinked at him in confusion. Of all the things the man could have asked him... and he asked about a pocket watch. Frowning slightly, Harry pulled his hand into his pocket and fished out the pocket watch, face up. It was as always warm, as if it had lain in the sun for hours and Harry welcomed the heat, using it for comfort as he had so many times before.

"I've always had it..." He whispered in a tiny voice, wondering what the Doctor was going to do now. Then the man withdrew a hand from Harry's shoulder and with trembling fingers, he turned the pocket watch around. The other side of the watch was engraved with circles upon circles upon circles, all overlapping each other and connecting with dots and lines, creating a sort of beautiful artwork Harry could stare at for hours.

Instantly, the man took a sharp breath and when Harry met his eyes he was shocked to find that they were filled with tears. Tears of joy, sadness and guilt all at the same time. Evidently, Donna was as shocked as Harry, because he heard her gasp.

"Harry, I need you listen to me, don't interrupt. Yeah?" The Doctor's voice trembled as he spoke and Harry could feel the raw emotion coming from him in waves. He nodded though, gazing into his eyes.

"I am the Doctor, I am an alien from the planet Gallifrey and that," He glanced up at the TARDIS upon which Harry was leaning on, "Is my spaceship." He paused, seemingly to collect his thoughts. "Gallifrey is lost now, there was a war... I am the last known survivor. The last Time-Lord. Our race had a little trick, we could turn into humans, or any other species, using a device called the chameleon arch, we would forget who were, and our minds would cook up a background story for us. Our initial DNA would be stored in a pocket watch, one with our names and our origin stamped on the back," As he finished, Harry's shocked gaze dropped to look at the innocent fob watch lying on his palm and he took a deep breath.

"If I understand this right, and I usually do," a small smile stretched on the Doctor's face, "And if I were to believe you, and I do," the smile grew a little bigger, "My proper DNA is stored in here," Nod, "And to become the proper me, I would have to open it."

The Doctor nodded again. There was a small silence were everyone heard Donna shifting from one foot to another, obviously wondering whether she should stay for such an intimate moment.

"What does it say?" Harry finally asked, his thumb stroking the circular pattern etched into the metal. The Doctor reached out with one hand and cupped Harry's cheek, awe and hope clear on his face.

"The Doctor's son, Omega Sigma,"

There was a moment of silence which was only disturbed by Donna's sniffles. Eventually, Harry raised his eyes to look back to the Doctor.

"You're my... Father?" The word felt very foreign on his mouth and Harry was sure he hadn't ever spoken it out loud. The Doctor though let out a chocked sob and nodded once.

"You're mother..." His face darkened, "Was Lily Evans, a human. But the human gene is recessive. She betrayed me and married James Potter. I never knew she had my son..."

"So if I... open the watch, I go back to being me?" Right, that sounded odd. The Doctor nodded again. Harry closed his eyes tightly and closed his small hand around the watch. Privet Drive, or his father? Well, it wasn't that hard to decide.

Cracking his eyes open again, he gazed into his father's hopeful expression and he smiled happily. Then he flicked the latch open.

Wow, I wasn't expecting to write so much for my prologue... But you know... stuff like this just sort of happens.

I hope the meeting scene was alright.. I'm crappy at any emotional scenes, so I hope that wasn't too dramatic.

So... any ideas for the future of the story? Any thoughts? Would you like Harry to regenerate into a new person (when he opens the watch) or do you want him to stay the same? Should Jack Harkness come in? Should Harry go to Hogwarts? And if so, at what age... and why? Should the Doctor and Harry manage to save Gallifrey somehow?

So there, I've given you guys something to think about (and possibly review about :D) so yeah...

Thanks

Should I continue writing it?
