Miss Memory

Prologue

Buffy. Sixth year.

"But Ja-ames!" she whined, complainging more for the fun of it than for the need.

"Buffy! I already told you. Mom said that we aren't allowed to teach you how to do it." He still wanted to know how she even discovered that he and two of his three best friends had each connected with their animagus forms anyways.

Pause. "James. I already know how." She said, rolling her eyes.

"What?!" he gasped, and sometimes the blonde girl beside him wondered how he could be so clueless.

"Oh puhlease James! I am your twin sister, and around the rest of them 24/7. Did you really think I wouldn't find out easily?" She sounded perplexed, but then, James was a male. And has both a male of the species and her brother, he had no perception despite the fact that they were twins.

"Quit going through my head little sister." He replied annoyed. He knew that she could do it without him knowing. She could look through her twin's mind with ease.

"By two minutes, and maybe later." She replied. Eliszabeth grinned cockily at him and he just let it flow away from him. He could never keep something secret from her no matter how hard she tried.

"Buffy..." He started.

"I know, you'll tell, but when has that stopped me?" she asked, turning that over to him.

"Okay, Phoenix, what is your animagus form, then?" he asked, giving in. He knew it was the truth. She had been raised with him. After all, they were twins.

"Why do you think I picked 'Phoenix?'" she asked, giving the idea a start.

"But we've always called you 'Phoenix, Phoenix." He said, not quite getting it yet. What could she say, her brother was slow.

She sighed, annoyed, stopping him momentarily in his palce. "Yeah, but you know how I've always felt about them. Now I just know why." She told him. Inwardly, she already heard that comforting son within and could feel the him of cool air brush against her face.

"Cool…" he started. But he got annoyed and got back on subject. "But you still-" But he was cut off.

"I know, I know. Besides, Lily totally has a crush on you." She said, changing the subject with ease and quickly brought his mind along to the path she wanted.

/"Buffy. You're brother is stupid beeping wannabe freak that ... clumsy oaf!" "Of course he is. He's a guy." "Yeah, but he's stupid, and rude, and, and just plain... rude." "Right." Looks thoughtful. "What?" "Oh, nothing. I was just thinking..." "What? Buffy, you've got that look..." "I don't have any look." "Yes. You have that look that you are planning something." "I'm not planning anything." "Okay, but if you do, then I'll have to beat you with my broom." "Okay. If I plan something that you don't like within the next few days, then you can beat me with a broom." Lily didn't catch the slip that would ensure Buffy's plan. She might have, but currently had her red head stuck in the nearest Potions book./

"Really?-" He was speechless (and what Buffy knew as his looking excited) until he caught himself. "Wait. I don't care. Tell her to go and get a boyfriend," he said suddenly, catching himself. He had given up on Lily Evans. Really. There was nothing left of his stupid crush that Evans had done her best to, eh, crush.

Honestly.

"Oh, I plan to." She smirked

"Good." But inside, he was getting a little jealous and mad.

"Great." She said, as she saw the various quick-play emotions running across his strained face.

James, somehow, missed Buffy's mischievous smile as she directed the conversation away from the no-no and they both walked into the living room. Really, Eliszabeth didn't understand how he continued to think she was pure Gryffindor in that she could direct words any way she desired.

As Buffy stopped and James walked past her to the bathroom, Padfoot, Moony, and Wormtail were gathered in the living room.

"Phoenix," she rolled her eyes at the plead of the 'puppy dog,' "what is goin on in your head?" Sirius asked, though he'd never dare walk into it, as he saw the look on her face. The other two boys looked at her as well.

"Oh, nothin." She replied in a ditz-like manner. They didn't stop looking at her expectantly.

Buffy could easily act like the dumb blonde that many thought her to be. Very few people really realized that she was very smart, with a top IQ. No one really noticed how she could weasel her self out of anything. Of course, she had told the guys to kill her if she ever started acting the dumb-blonde 24/7. She needed her 'special time' to act herself.

The fact that she repeatedly packed her trunk and wardrobe with clothes was just something she liked to use for her feminine aura, despite the fact that she didn't have the hots for any of the boys at Hogwarts.

"Riiiiight... and I'm a potato covered in sour cream and onion." Wormtail said, unconsciously licking his lips.

Buffy looked at him. Doesn't matter how close she was to him and the others, she didn't really trust him. 'Well, I don't think that'll be far off in the future, say about 20 years.' she thought, before brushing off the thought. It wasn't like she was mean to him… but for some reason, Peter Pettigrew had always given her the creaps.

Although the young Hogwarts student knew that the sort of pudgy boy could not academicly intimidate her, there was just something that bothered her. But she would say nothing. He was her brother's friend.

But instead, she said, "Just James and his crush." she said nonchantily as she looked up to the ceiling with an innocent contemplative tone.

That perked the guys up. "Who?" Remus asked.

"That would explain that..." Sirius said, thinking about a dreamy, scowly look James had had the day before. Sirius knew his fellow marauder had not been really paying attention to the update plan at the moment.

"James has a crush?" Remus, Padfoot, and Phoenix looked over at Wormtail with a 'Duh!' look. He sat down with an embarrassed look on his face. Sometimes, Peter could be really oblivious.

Buffy turned back towards the rest of the group. "Of course, can't you guys tell?" she asked, pure self-assured arrogance nearly bleeding from her smile, her white teeth gleeming like a monstrous secret half scaring them away.

They looked at her with the look that said, 'if you don't tell us now...' and she just smirked. Intimidation of James's little sister was not something they were particularly good at; especially Moony despite his Werewolf status. He had such a calm and studious nature. Sometimes, she wondered how such a nice and sensical guy ended up with her brother and Sirius 'just dare me' Black.

"Well, if you don't already know, do you really think I'll tell you guys something that useful?"... She let the sentence end. "Give me a week; they'll be together by then." Turning away and ready to flee up the stares, she waved her tush seductively, not really meaning to make them look at her as a woman, but more to show how superior to the minds of young men that were not in the know.

They looked at each other (the boys) and a silence hung over the air while static jumped between them; they seemed to share one mind in a question. That's when the three guys tackled her as if they really did share one brain, and started tickling her mercifully.

"Who?" Padfoot jumped with the question.

"Do we know this girl?" Remus asked.

"It is a girl, right?" Sirius asked. He wasn't really being earnest, but he had to ask.

"Of course it's a girl, don't be dumb." Lupin responded.

"Is she pretty?" Wormtail asked, cheekily.

"How does he know her?" Remus asked.

"How does she know him?" Black asked, continuing on in their inane pattern.

"How do they know each other?" Lupin looked curious.

"Do they know each other?" Wormtail asked, truly sounding inane.

"Of course they do." Lupin said, this time speaking momentarily to Wormtail, but sounding as if he was adressing the world at large.

"They do right?" Padfoot asked.

And that's what and over-protective James found as he slowly slunk down the wooden stairs. "What the bloody-hell are you doin to Phoenix?!" he said aloud.

The boys jumped up, followed by Buffy, whose blouse and skirt were ragged with wrinkles. Her cloak from school lay abandoned on the floor.

At the look on his face, all four of them cracked up.

They'd continue their conversation later.

"What do you mean 'James is in the Forbidden Forest'?!" Buffy yelled at Sirius, as if he was the one responsible for looking out for James. Which wasn't true, it was Moony who had the unfortunate responsibility of making sure neither of those two did something too stupid.

"Well, it means-" He began, immediately screwing up his chance of surviving the youngest Potter; afraid that he was about to get an outburst out of the younger Potter twin, he winced and looked at the werewolf. Both knew that James got one of those dangerous Mt. Phoenix eruptions only a few weeks before, and he immdeiatly decided he wanted to live; James had turned and retreadted to a safe distance from her for a whole week straight. That had put the others in their place as well.

"Yeah. I get what it means. What I mean is 'How could you just let him go?!" She yelled again. Instead of echoing through the forest from the edge of the school as the tone and pitch was meant to, it seemed to cacoon the other Marauders in her voice and their very fear.

"Buffy, you know how he is when he is onto something." He said slowly, backing away as they tried to calm her. 'he is almost as bad as you.' He thought.

"Yeah, Sirius, I know." She said, forcing her rage back into her petite young body. "But you could have just called me!" She screamed right in his face. Then she walked off into the forest with a Lily, Wormtail, Sirius, and Remus all straggling behind her. She knew her way, it appeared.

"Yeah, I know Buffy… but," he weedled, "Lucius challenged me to the duel, and" he started, trying his best to make excuses for incurring her fury and wrath. He was afraid of his little sister when she got like this. Her blonde hair seemed to fizz and sparkle around her like Medusa. Little bright sparks of plasma seemed to float around her and hiss as if they were truly snakes dancing to her command.

She was worse then 'his lovely Lily,' whose hair seemed to alight in flame when angered.

"So what. Win." She said, knowing that the Potter line wouldn't back down from a good fight. "But be careful!"

He shrugged, just hapy that he got out of her stormy anger. But wasn't the calm before the storm? He seemed to think. "You know me." He said, without thinking.

She got that look in her eye and he instinctly knew that he had said the wrong thing.

"Oh-kay, okay, I'll be careful." He returned, trying to save his hide so that he could actually go to the duel.

"You better be." Then she took a look at him and squinted her eyes, motioning for him to take her seriously. "James Henry Potter, If you die, I'm telling!"

He smiled then; he really did love his little sister. Even of she could be a handful. She was really protective.

The duel was over, and Lucius went and sulked, secretly, up to his room in Slytherin. The male marauders sighed in relief and smiled happily at James's winning.

And then, they saw them.

As the girls ran at the boys, a small sweeping motion was felt by all, but was soon ignored as Buffy's feared voice was heard. The boys tried to hide their reactions as they shook with fear.

"Prongs! I may be two minutes younger, but I am older in far more ways then you are! What do you think you are doing?!" She nearly screamed and ran at him. He had apparently done something quite dangerous, and she had seen them.

Sirius had gotten beside his best friend before her, knowing where the duel was going to end, instinctively.

"Yeah, oops...?" He said, trying to back away. His raggedy hair that never calmed seemed to retreat into a flat balck hat in fear.

"Oops? That's all you have to say?!" she seethed outraged. He, as well as the other three boys behind him got ready for her to blow up, and slowly moved backwards as well. And Lily, who was standing behind her, grinned happily at the about-to-be-punished boys.

"Well, at least its better then your last reason." Buffy said as she smiled.

Lily, who was as clueless as the boys for a second, got hot headed, so she finished it. Buffy stepped out of her way, as Lily walked up to a standing scared James, and seethed.

But before she got the chance to say anything, Buffy stepped up behind her and pushed her into James's arms; and before any of the boys, and Lily, knew it, they were kissing mindlessly.

Lupin, Black and Wormtail got pushed down. And when they realized what she did, they all had smiles on their faces. And then they all scowled for a second. Then Peter blushed, Sirius cracked up, and Remus said, "Well..."

Buffy smiled, satisfied. Then she thought about it. "Hey, It only took me five days." she looked down at the three on the ground. "Pay up." She put out her hand. She had a handful of money in her hand. Yeah, she was rich, but money was money after all...

They said a few more words in good fun, before the whoosh of something none knew was real, and preferred not to be called crazy by another if they told took place, and they were left to try to drag James Potter and Lily Evans apart. The couple preferred to be in the other's arms then anything else.

Buffy was contented, basically happy.

A week later, Hogsmaede was attacked by unidentified people who appeared to be death eaters, but with closer inspection, were found not to be. They were actually assassins hired by the watchers council to take out Buffy or capture her-whichever works.

One of the council operatives transfigured a bench near him into a replica of her body. She was chloroformed, and taken away.

The wizarding world was outraged at her death, and even though they were found not to be Voldemort's people, most wizards and witches ignored it, and the death of Buffy (Elzisabeth) Anne Potter was taken as a great tragedy to all. And the danger level for the dark lord rose higher.

The young lovable twin of James Potter had a great impact on the wizarding world. Little did she know, that she would have a great impact on the muggle world as well.

TBC of course. This is updated slightly. Lucius is no longer luscuous, (though truly I wanted to call him 'gross'ous) and there is some more to read inbetween so it isn't totally boring. Enjoy and I will try to locate my muse for this.
