Showdown

Chapter 1- An Introduction.

Libby Silverman sat in her large, empty house by the unlit fireplace. Her snake, Ryn, was coiled up beside her whilst her pet cat, Star, was hunting in the long, overgrown grass for mice near the front porch. Libby felt no remorse for having no family; her two pets were the only company she needed. She was just sorry she had to leave them to go back to school...

Libby attended Hogwarts School of Witchcraft and Wizardry, which, not suprisingly, meant she was a witch. Her three best friends were Harry Potter, Hermione Granger and Ron Weasley. She had been friends with Harry before Hermione, and even before Ron. It didn't matter to any of them though; they had known each other since the first year, and had been through thick and thin together.

Most of Libby's life was a mystery to everybody except Libby herself. Even Dumbledore was slightly clueless when it came to this particular student. There were so many things her friends didn't know, but she preferred it that way. The first years of her life had been dangerous; Voldemort had killed Libby's parents just before his downfall by Harry Potter. For some reason, Voldemort had not even tried to kill her. Maybe it was because, even in her one year old ignorance, she had just stared at him through her deep, unblinking brown eyes. Or maybe it was because she had remained steady, and hadn't even shook when Voldemort had held a wand right next to the temple of her head, before pulling it away decisively.

Another secret was that she was a parselmouth, like Harry, which enabled her to speak to her snake, Ryn. When she was just a child, Voldemort had made her stronger somehow. All she remembered of her very early childhood was a lot of people dressed in black cloaks, and passing something onto her, like...power. From a very early age, she could remember being able to do things, make things appear etc, but only used spells when absolutely necessary, and usually resolved to the simple 'muggle' way of cooking, cleaning and, of course, watching the television.

Last of her 'big' secrets was that she strangely had four godfathers, probably due to her father not deciding who out of his best friends would have this honour. They were James Potter, Remus Lupin, Sirius Black and ...Severus Snape. She did not live with any of them however, and often lied when asked directly by one of her godfathers, saying she lived with either one or the other. Sirius had only found out she was still alive two years ago, as he had been in Azkaban, but each of them believed she was dead until she appeared at Hogwarts when she was eleven. Libby was actually related to Severus, although quite distantly. He had been her father's cousin, but regardless, he was her only living relative.

When stumbling upon some of her fathers old diaries, she found that the only reason that her dad had not 'hung around' with the Marauders at school was because he hated Peter Pettigrew with a loathing. Thus, her father had resolved to being Severus' friend.

At that particular moment though, Libby wasn't thinking about any of these things. She was actually having flashbacks. These flashbacks seemed real...so real. It was like her whole school life was flashing before her eyes; one memory for each school year:

**Libby stared out of the train window as she travelled to Hogwarts. Finally, she was going somewhere she had always dreamed of; meeting the famous Albus Dumbledore, making new friends...yes, Hogwarts sure did seem sweet. The carriage door slid open.

"Um, hi. Do you mind if I share your carriage? Quite a lot of people seem to be staring at my forehead in all of the others."

Libby stared at him, hardly able to speak. This boy...this was Harry Potter! A boy she hardly knew at all, but seemed so familiar. It was him, it had to be. He even had the scar- the scar he received when-

"So? Can I come in?" He smiled, feeling slightly anxious at the way Libby was looking at him.

"Harry? Is that you? She managed to choke out.

"Uh, yeah, it's me. Sorry, but do we know each other?"

Libby seemed to snap back into reality. "Yeah...we-our parents knew each other. They were old friends." Libby smiled for the first time.

"Our parents knew each other? YOU knew my parents?!" Harry asked excitedly.

"Well, yeah." Libby replied hurriedly. "My mum told me about your parents and stuff. I have memories, as well." She added.

"Wow," Harry took a deep breath. "I'm surprised that you can remember back that far. I wish I could." He stated solemnly.

Libby was just about to change the subject when someone else came bursting through the door.

"Sorry," Apologised Ron. "Do you mind? All the other carriages are full."...**

This flashback stopped, but another soon came into her head. This time it was a memory from the second year.

** "Harry, we can't get out! We're trapped behind these rocks!" Screamed Libby from behind the rock, which was blocking their departure.

Ron agreed. "Harry, you have to go on. Ginny's down there. Please, I don't know what I'd do if...if..."

"Don't worry Ron," Stated Libby clearly. "Harry won't let us down, right Harry?"

"Right." Harry hated pressure being put on him, but he knew he had to do all he could to save Ginny, not mentioning the poor victims who were petrified (including Hermione), so he set off down the deep, damp cave...**

Libby's eyes remained open as yet another vision flashed through her mind.

**Harry stood over Sirius Black with his wand in his hand. He had to kill Black, Black had killed his parents, and he deserved it. Harry became only vaguely aware of a figure behind him until it spoke.

"Harry!" Libby yelled. "What are you doing??" She muttered a spell under her breath and Harry's, Ron's and Hermione's wands flew into her hands. She then walked over the dusty floor to where Sirius and Crookshanks lay. Libby then held out her hand. Sirius grabbed it gratefully and with surprising strength, she hauled the man off of the floor. They then hugged. Sirius, who had tears in his eyes, whispered, "I thought you were dead...the funeral...how can this be? Oh Libby! You're alive."

This statement must have been overlooked in the desperation of the situation. Maybe the others would have made a bigger deal of the words 'alive' and 'funeral' if they had been sitting quietly in the common room.

Nevertheless, it was obvious to Harry, Ron and Hermione what was going on here. Libby was working with Sirius Black, and AGAINST them.

"You traitor" Harry spat through gritted teeth.

Libby looked over only slightly disconcerted. "Look Harry, I better just let Sirius tell you his side of the story." She said, making her way to the exit.

"Oh no, you're not going anywhere." Said Harry menacingly, blocking her way.

"I said GET OUT OF MY WAY!" Libby shouted, pushing the wizard out of her path. As Harry felt the full force of Libby's strength, he realised how the young girl had managed to pull Sirius up. "I'll come back later, shall I?" She added, before leaving the room and marching down the stairs, hardly noticing that she had passed Remus on the way.

Thirty minutes later, she crept back up the stairs when she heard several curses being said at the same time. When she had reached the summit of the staircase, she found Severus lying unconscious next to a wall.

"Jesus Christ," Libby exclaimed. "What did you do to him??"

"Why do you care?" Sobbed Hermione. She thought the rotten old potions master was the least of their worries at the moment. Even in this tight situation, Remus and Sirius gave each other a knowing look; it was obvious Libby hadn't told her friends about the whole 'being related to Snape' subject...**

Libby was bought back into real life by the chiming of the old wooden wall clock, which hung loosely over the front door.

"2 o'clock??" She exclaimed more to herself than Ryn. She was meeting Ron and Hermione outside Flourish and Blotts at 3. She had to get new robes before then, and it would still take twenty minutes to walk to Hogsmeade. She had to leave now, and say her goodbyes to Ryn and Star.

"Star!" She called from the armchair. Her cat obediently trotted in. She had almost certainly been successful in catching mice.

"Look, guys." She said tenderly. "I'm going to have to go now." There was an immediate hiss of protest emitting from Ryn.

"No, I have to. You know the score...I've done it four times before. Look," She said lovingly, stroking the top of Ryn's head. "I'll be back before you even know I'm gone." She joked. "See you later." She was now stroking Star. Then Libby walked over to the door, grasped her worn battered suitcase and left.

"And don't forget to look after each other, or you'll have me to deal with!" She called through the letterbox.

So? How was the first chapter? I've had this story floating around my little ol' brain for quite a while. It will get more interesting, trust me, but this chapter was mainly for explaining who Libby was and that she has always been around. Only in my world though.
