Title: Clarke's Third Law

Author: tinyrose65

Summary: Any sufficiently advanced technology is indistinguishable from magic. So what happens when witch meets scientist? Things become a tad confusing. And more than a bit fantastic. Doctor/Rose

AN: Alright, so this is the first chapter of my new series, which will basically be a Doctor Who/Harry Potter crossover, with Rose Weasley replacing Rose Tyler, and another other appropriate changes like this. The story will span from Season 1 to the end of Season 2 (So spoilers! Beware!) and will really be more like a collection of one-shots, drabbles, short stories, and rewrites of certain episodes, all set under the same title. So, enjoy and on with the story!


"I've got a secret!" came a singsong voice by her head. Rose jumped, books and papers flying everywhere. Shareen Costella, a Gryffindor in her year, smiled at her. Madam Pince, the now ancient librarian, fixed them both with a stern glare. Rose gave her an apologetic smile. When she turned away, Rose shot the taller girl a glare.

"Are you trying to get me expelled?" she whispered crossly. Shareen rolled her eyes and plopped down into the seat next to her.

"Like they'd ever expel Rose Weasley." Rose grimaced as, once again, her family's legacy was brought up. She huffed.

"You need somethin'?" Rose asked, impatiently. Shareen was nice enough, but the girl could talk for all of England.

"I told you," Shareen repeated, "I've got a secret."

"And what?" Rose asked, closing her books and giving up all pretenses of studying. "I'm supposed t'guess what it is?"

"No, you're supposed to ask me straight out."

Rose blinked and was reminded of why she never spent much time with the muggleborn. She decided to play along. "Will you tell me what it is, then?"

"Somebody likes you," Shareen said cheerfully. Rose couldn't hide her interest at this and didn't even bother trying.


Shareen grinned at her, triumphant. "Jimmy Stone."

Rose let out a low whistle, before studiously avoiding Madam Pince's eye. Jimmy Stone was, like her, in seventh year at Hogwarts. He was in Hufflepuff, though, so she knew very little of him other than the fact that he was very popular, a very good Chaser, and very gorgeous.

"How'd ya know?"

"I heard his mate Mickey talking to his girl Trisha who told Keisha who told me!"

"Right," Rose said, nodding sagely, "straight from the horse's mouth."

"C'mon Rose," Shareen begged.

"You're just sayin' that 'cause you've got a thing for his brother." Rose deadpanned. Shareen made a face.

"'Course not! I'm thinkin' about you!"

"No you ain't.."

"Fine," Shareen conceded. "but you can't deny that his brother is a bit of all right!"

Rose couldn't help but grin cheekily. That was a point that nobody could deny. Even some of the professor's had been known to fall prey to Ryan's trademark dimples. Jimmy might not have had the same charm as his brother, but there was something equally appealing about him. Rose bit her lip made her decision.

"Are you sure about this?"

"Of course I'm sure!" Shareen called out over the cheering. Shareen had managed to drag her out to the Quidditch game between Gryffindor and Hufflepuff. Gryffindor had won (How could they not? With her cousin Al as Seeker?), but Rose wasn't headed to the party that was sure to take place in the common room. Instead, Shareen had given her a good, hard shove towards the Hufflepuff locker room to wait for the team to finish getting changed.

Jimmy Stone. Changing. Merlin's beard.

"Can I help you?"

Rose felt her face flush red as Jimmy himself appeared. "'ello," she greeted cheerfully.

He smiled at her. "Hello. Rose, right?"

Rose smiled, despite the small pang she felt in her chest. He knew who she was; of course he did. She could give him points for pretending otherwise, though.

"That's right," she told him, brushing her blonde hair away from her face. "And you're Jimmy. You played a great game today."

"We still lost," he grimaced. "Not that anybody can really win a game against Gryffindor these days. Not with your cousin Al as Seeker. He's brilliant."

"He takes after his dad," Rose shrugged it off.

"But it begs the question," he continued, a smirk on his face as he walked closer to her, "what are you doing here? You should be celebrating."

"I should be," she admitted, "but then I thought that it'd be pretty selfish of me. Thought maybe you could use some consolin'."

"I have been devastated by the loss," he told her.

"Yeah, I can tell," she told him, mock seriously. The smile on his face got larger. "Good thing I've got the perfect remedy, though. How's a butterbeer next weekend at the Three Broomsticks sound?"

"If thats what I get for losing, I don't think I ever want to win a game again. House Cup be damned."

First Date

"How do I look?" Rose twirled theatrically for her cousin, Lily. Lily looked up from her magazine and gave her friend an appraising look.

"I like it," she nodded, approvingly. She frowned. "Keep your hair down, though. Looks better that way."

Rose obliged. "Where's your brother, anyways?"

"Downstairs, doing something or other," Lily waved it off. "Probably keeping your brother company."

"Whad'ya think they talk about?" Rose asked, the thought suddenly coming to her. Lily shrugged, once again unconcerned.

"I wouldn't worry about it-at least, not now. You're going to be late to your date if you don't leave soon."

"I'm goin', I'm goin'." She muttered, grabbing her bag and her wand before heading out the door of the dorm. She paused in the common room. Sure enough, Al and Hugo sat huddled in the corner. Rose recognized the Marauder's Map spread out between them. She rolled her eyes and sauntered towards them

"If you're plotting to mess up my date with Jimmy, I'll kill you, yeah?"

"We've got better things to do then mess up your date with that idiot," Hugo denied, scribbling something down on a piece of notepaper. Rose frowned at him.

"Just 'cause he doesn't have your brains, don't mean he's an idiot. 'Sides, by that logic, I'd be an idiot, too. Is that what you're saying?"

"Of course not, Rose," Hugo muttered, not looking up at her. Rose's draw dropped indignantly and she turned to glare at Albus, who was watching the entire thing, obviously amused.

"He does think I'm an idiot, don't he?" she demanded crossly, her hands resting menacingly on her hips. Al eyed her warily, knowing that she could cast a hex like no other, a trait she happened to get from her mother (along with her looks...how she had managed to evade the trademark "Weasley Hair" was still a mystery).

"Nobody here thinks you're an idiot, Rosie," he assured her. He nudged Hugo firmly with his elbow. "Right, Hugo?"

Hugo finally took the opportunity to look up from whatever prank he was planning. Taking in his sister's angry scowl, he gulped. "O'course not! By the way," he said, quickly changing the subject, "you look lovely."

"Yeah," Al said, catching on, and nodding enthusiastically, "very lovely. But if you keep hanging around here, Jimmy will never get a chance to see for himself."

Rose let out a string of curses that would have had her mother washing her mouth out with soap had she heard. Al and Hugo exchanged amused glances as she darted out the room before glancing back at the Map. Hugo frowned.

"But how are we going to get the feathers in her office in the first place?"

Rose forgot completely about her brother and her cousin and the monumental prank they were probably going to pull. Its none of my business whether or not they get expelled, she thought firmly, a dreamy smile on her face as she listened to Jimmy describe the time that he and his brother had come home early from a local Quidditch Match and found his parents in the middle of a rather passionate snog.

"Thats nothing," Rose denied. "I once walked in on my parents in the middle of...well." Rose gave Jimmy "The Smile." It was her father who had first capitalized it, telling her, "I'm not the only man you'll have wrapped around your finger, if you keep smiling like that. That said, I'm probably going to have to glue your mouth shut."

"You're joking!" Jimmy laughed at her. Rose shook her head sheepishly.

"I was only two, amazingly enough, and I still remember it like it was yesterday! I'm pretty sure its where Hugo came from, too!"

Jimmy almost spit out his drink at that, and Rose smiled wider. The night had been a success, so far. They had eaten a quick dinner, then ordered some heated Butterbeer, which they now drank as they wandered around Hogsmeade. Rose made a show of shivering heavily, using it as an excuse to move closer.

Jimmy placed his arm around her shoulder and looked at her warily. Rose gave him a large smile to assure him that it was alright.

"I had a great time tonight," he offered, as they approached the entrance to Hogwarts. It took Rose a moment to realize that they had been walking for over an hour. She shivered again, this time for real.

"Yeah?" she asked him. He nodded.

"Yeah." He was quiet for a second. "We should do it again?"

It came out as a question and Rose laughed, her breath misting in the cool air. "Are you asking me or telling me?"

"Er," Jimmy said, frowning, "It depends on your answer."

Rose answered his question by standing up and giving him a quick peck on the lips. He blinked, confused.

"Is that a 'yes?'"

Rose resisted the urge to sigh, exasperated. Hugo was right: he is an idiot, Rose thought. She grabbed several fistfuls of his hair and pulled him down towards her for a snog that was sure to erase any doubts he had.

First Fight

"What do you mean you were busy studying?" Jimmy demanded. Rose threw her hands up in the air.

"I meant exactly that! I was studying!" She and Jimmy had been dating for several months now-several glorious months. Keisha had warned her that the honeymoon phase would be over soon, but Rose hadn't listened. Keisha had a new man every other week. What could she know about that?

Rose knew now that she should have listened.

There had been another Quidditch game the night before (Hufflepuff versus Ravenclaw), but Rose had opted out of it, choosing instead to do a bit of studying for her Potions exam. Just because her mother's brains had gone to her brother didn't mean that she didn't want good marks. She and Al had plans to train to be Healers together. It was a dream they had shared since they were little.

She had thought that Jimmy had understood that, and the sacrifices that had to be made, but it seemed that he didn't.

"I had a Quidditch match yesterday!" He told her angrily, face red. "You should have been there, supporting me!"

Rose scowled. "Let me explain something to you!" She snapped. "Just because I'm dating you, Jimmy, don't mean my life is on hold! I don't have to do everything for you! I gotta do some stuff for me, too! And I told you before, I need to pass my NEWTs if I want to become a healer-"

"Let me explain something to you," he interrupted. "When I was playing last night, and looked out into the stands, I saw the girlfriends of all the other guys on the team, but not mine. How do you think that made me feel?"

"I'm sorry, but-" Rose tried.

"But nothing! And I hate to break it to you, Rose, but you aren't going to be a healer anytime soon. The only way that would happen is because of your parents! So get your head out of the clouds and start showing up to my games!"

He huffed and then stalked out of the empty classroom that he had pulled her into for their argument. Rose huffed in annoyance and anger, tears welling up in her eyes. Somehow, in the course of one argument, Jimmy had managed to drag up her one true insecurity.

"Its not true, you know?" Rose hastily wiped tears from her eyes and looked over her shoulder. Al was standing hesitantly by the door. She turned to face him fully.

"Ya heard that, did ya?" She asked shakily. He gave her an apologetic grin.

"I think everybody heard it," he informed her. She snorted.


"Its not true, Rose," he repeated, firmly. "Don't you dare believe him. Not for one second, alright?"

"Whatever you say, Al," she muttered, walking past him, out the door.

Al sighed and watched her sadly. This was not going to end well.

He didn't need a passing grade in Divination to know that.

Last Fight

"Its over, Jimmy!" Rose screeched. She didn't care how loud she was being or how many people were probably listening in. She had enough with Jimmy-bloody-Stone and his ridiculous mood swings. Over the course of the last semester, Rose had spent more time and effort trying to keep him happy than on her studies. She had slowly abandoned her friends and her own hobbies, just to spend time with him.

She thought it would be worth it, but that was until she caught him with another girl in one of the Herbology greenhouses. Her fierce glare had sent the girl running for the hills, but Jimmy had decided to stay and defend himself. He wasn't going to be able to talk himself out of this one, though. This was different than all those other times when she had fallen for his explanations and sweet apologies.

Blimey, she had been an idiot.

"Its not over," he snapped. "Its not over until I say its over!"

Rose shook her head in disgust, suddenly reminded of their first ever fight. The reason as to why her judgement was clearer now than it was back then was still unknown to her.

"What did I ever see in you?"

She went to leave, but a firm hand on her arm stopped her. "Hey, we aren't done here!"

"Let me go," she snapped, not in the mood to be patient with him. His hand gripped her tighter, almost bruising. For the first time since the fight started, she was actually afraid of Jimmy. "Please," she said quietly. She tried to struggle, but all that did was make him more angry. He shoved her, hard.

She cried out as her head hit the corner of one of the desks. She tried to scramble up, but was unable to do so due to Jimmy's towering position over her. Rose heard the door open.

"What's going on in-" her Uncle Neville's voice voice suddenly uttered something unsuitable for younger ears. "Get away from her!"

A flash of light and Jimmy was lying on the floor, stunned. Rose wondered whether or not it was appropriate for a professor to stun a student, but she barely had a chance to look at Jimmy when her uncle was kneeling down next to her. She felt him gently pat her down for injuries.

"Somebody go get Madam Pomfrey," he ordered firmly to one of the students that had no doubt gathered at the door. Rose couldn't really understand much of anything that was going on at the moment. Her head was swimming. "Rose," called her uncle, his voice sounding worried despite the fact that it was slurred, "I need you to keep your eyes open, alright? Do not fall asleep, okay?"

"'t hurts," she murmured, closing her eyes. She heard her uncle calling for her more frantically and the sound of feet padding into the dirt ground of the greenhouse. "Sorry."

The last thing she heard was Madam Pomfrey's professional voice and her Uncle telling her that there was nothing she needed to be sorry for.

"Nothing at all, Rosie."

NEWT results

That had been three months ago. She had woken up in the Hospital Wing with a pounding headache, but, thankfully, no other injuries. Her parents had been rushed in and had been nothing but understanding...well, once her father had finished threatening certain death to Jimmy, anyways.

Madam Pomfrey had held her for a few days, during which she had to give a statement to some Aurors, but she was eventually released.

As much as she hated the Hospital Wing, Rose missed it immediately. Everywhere she went, peopler were whispering about her, pointing at her. Al and Hugo had been great support, and so had Lily. They were more than happy to spend hours in the Library with her as she struggled to catch up on all the course work she had neglected while with Jimmy.

She had known it was pointless, though. There was no way she was going to be prepared enough for her NEWTs. She might pass, but she wouldn't he able to get the grades she needed to become a healer.

Al had denied this, telling her that she was wrong and that she was more than smart enough. Hugo had helped her study, creating a schedule for her and lending her his notes. Lily had snuck her food from the kitchens when she skipped meals and helped her get to bed when she stayed up late.

All of it had been for nothing, though. Al had pulled all E's and O's, but Rose hadn't been able to keep up her end of the deal. She stared at the abysmal NEWTs in her hands.

A's across the board, save for one (miraculous and lonely) Outstanding in Charms.

They weren't the most horrible marks in the world, but she could forget about becoming a Healer. To do that, you needed at least an Exceeds Expectations in Charms, Potions, Transfiguration, Herbology, Transfiguration, and Defense.

This the moment when Rose Weasley learnt that mistakes are easier to make than to fix.

I'll probably be doing Rose (the pilot), Father's Day, Christmas Invasion, ROTC and AoS, and Doomsday. I was also thinking about doing The Empty Child/The Doctor Dances, but I'm not sure. On one hand, its a great episode and I love Captain Jack (Plus, who else wants to see Jack's reaction to magic?). On the other hand, it's rather long and I'm not sure if it would be worth it. Let me know, please! (There are a couple episodes until I get there, so you've got time to think about it). If there are any other episodes that you want to see, then let me know, too! Just review or PM me!

And...thats it, I guess. This chapter is a bit slow, but it's main point is to just get things started. We never get much information about Jimmy in DW, so I did with that what I liked.

Let me know what you think! Love it? Hate it?
