Author Note: Thank you for the reviews for my oneshot, everyone! This is a new one I thought of while watching Medical Investigation.

Hope you guys enjoy this one! Emerald


Firefly

Summary: Lily and James are both in Gryffindor and the same year. Oh, they're on a totally different social scale. Lily is an outcast with only one friend and James is at the top of the ladder. They've had many secret meetings but said few words to antoher. Now they get assigned together for a project. Two Weeks. Living together.

Disclaimer: I do not own anything recognize (i.e., Lupin, Black, Potter, Sinistra, and Evans, etc...). I own the plot, story, dialogue and others you don't recognize.

Chapter One: Lily

"Look at them. All vying for Potter, Black and Lupin's stupid attention." Sam Sinistra said in utter disgust.

"Give it up, Sam," Lily Evans said, rolling her eyes and concentrating on her Ancient Runes homework again.

"What," Sam said. She looked down at her Astronomy homework. "What do you want to be, when we're out of Hogwarts?"

"An Unspeakable or healer." Lily looked up and smiled at her friend. "And you want to be an Astronomy teacher don't you?"

"Yeah," Sam started. "I mean, I've loved Astronomy all my life. Ever since my mum... I loved the subject."

"I guess I do know don't I." Lily grinned and flipped her red hair over her shoulder. She stood up and began to pack her stuff in her book bag. Yesterday, and today's homework were completely done. She had finished all her projects that would be due within the next two weeks already. Sam followed suit.

"So are we going out tonight?" Lily questioned, walking out of the common room.

"Yeah, It's a full moon. The stars are beautiful out."

Lily laughed and shook her head. "Next time I ask- shoot me."

"If that was legal I would've shot you long ago, Firefly."

"Too bad, Uni. Too bad,"

"Don't I know it." Sam nodded her head vigorously. Lily turned to her with a devious smirk. "What you planning, Firefly?"

"Nothing- nothing at all."

"You may appear innocent, but I know you can be guilty as hell!" Sam grinned. "Now spill."

"Oh, you know that there's a werewolf in Hogwarts?" Lily asked as she shut the door. They had just entered the Room of Requirement.

"No. I didn't."

"Too bad. And I can't tell you who he is."

Sam raised an eyebrow. It had never ceased to amaze her how her best friend could sense what a person could say before they said most of the time. Lily smiled and continued looking out the window.

"I have a problem." Sam groaned, sitting sadly on a chair.

"What's wrong?"

"Davis. There's nothing there." Sam said shortly. Davis Henderson was a geek. Sam was only dating him because they were her grandparent's last wish. And Sam loved them to death so she listened and started dating him. They had been going out for 1 year.

Sam and Davis' relationship was similar to Lily's opinions on her parents' marriage. Despite the fact they kept up a cheery facade, she knew that they were never in love. There might have been something there, once, long ago... perhaps, long before she came into the world. Whatever was once there was gone, it was now replaced but mutual respect, a slight liking, and overall, no feeling. They were happy, though. It passed her understanding how they could be happy with this arrangement, but she never felt the need to ask them. Afterall, it wasn't her business, was what she could understand.

Understanding was what she was. Her mother had brought her up to understand, wanting her to be able to comprehend those around her. To give her a compassionate heart, an empathetic nature, had been her goal. Her parents had wasted no money on finding her the finest philosophers, moralists, scholars, and the like. It seemed as they had succeeded.

They had given her a greater understanding of the human psyche, taught her the ways of the human mind until she knew it like clockwork, and had helped her cultivate practically a sixth sense for detecting the emotions of those around her.

In an indirect way, they had given her ammunition against her superiors. She was able to read into their actions, expressions, gestures and words, with more accuracy than mind reading. She could predict their next words, judge their character, and, yes, understand them completely.

She never questioned these abilities; they came as naturally to her as breathing. On her own, she learned to flatter or flirt, whichever term you prefer, more effectively and insult others with equal potency.

"Sam, why can't you break up with him?"

"Lil... My grandparents, they wouldn't have wanted it."

Lily rolled her eyes and snorted. "They're dead, Sam! Are you going to spend the rest of your life miserable because of your grandparents last wish? Because if you are, then why the bloody hell are you brooding about it?"

"I KNOW their dead! I was the last person they saw! You know I loved them. A lot!" Sam yelled. "It was their last wish! And I can't disobey that!" With that Sam left the Room of Requirement with a slamming door.

Lily sighed and stared at the fire. Slowly she began to rise again, and taking her stuff, she left the room. With no intention of coming back later.

She went into a secret room that Dumbledore had put for her so she could train. There was a fireplace on the opposite wall, near the window. There were swords of all sizes, targets, a massive stereo system with a whole stack of CD's next to it (she had put those in- Dumbledore did the rest) and everything anyone could ever need to get fit, learn self defence or to get their powers stronger; muggle and magical.

Lily changed into a midnight blue vest top that clung to her like they were made specifically made for her and a pair of black short shorts.

Lily made for the punching bag and started punching it as if it were nobody's business. She did punches, kickes, low ones, high ones; you name them; she did it.

Lily as gutsy (she was a Gryffindor afterall!). She was powerful and capable, and- some might even say deadly.

Lily punched out her anger and frustations into the punching. She muttered, "Hello, misplaced aggression."

James

He had needed to get out. The girls were suffocating him. James walked around the castle until he stopped at a room that he had never seen before. He smiled. It would be great to add it to the Marauders Map.

James opened the door and stood there. Jaw slacking.

Unbelievable. Hair flying, limbs whirling, she was the most graceful, powerful martial he had ever laid eyes on. Her every move was a mesmerizing combination of ballet and kung fu.

The girl, whoever she was, she had the looks of a international supermodel and the speed of Superman.

James wondered why he had never seen her before. She was beautiful. He had to talk to her. He cautiously took a step inside and was amazed at the training center.

"What can I do for you Mr. Potter?" The girl questioned, stopping and turning to look at him dead in the eye. Her eyes were a deep, challenging, emerald.

How had she known she was there?

What the bloodly hell? James thought.

"Umm, I was just taking a walk around and I never saw this place before."

"Oh, if you could please leave, I'd like to get back to my training now. And please, do not try adding this to your Marauders Map as you most likely won't be seeing this room again."

How does she know about the Map?

"Please leave." The girl repeated coldly. James shrugged and left.

What he didn't see was that the moment to door closed, she broke down and cried her heart out.


Author Note: What did you think? Too descriptive? I'd like to thank everyone who reviewed to my oneshot "My Baby Sister". The reviews were GREAT! I hope to have a lot of reviews for this story. Thanks! Emerald
