~~THE TALE OF TWO SISTERS~~

SUMMARY: Isabella Marie Black is Bellatrix's twin sister. Therefore, she is also Andromeda and Narcissa's sister. Isabella, being the youngest in the family of Purebloods didn't help her cope with the whole family. She is simply ignored by most whereas Bellatrix receives more attention and more recognition. This is the tale of two sisters.

Prologue

In the middle of the night, down at the dark empty alley, there was a woman with pale complexion and dark brown hair that ends in the middle of her back. Her chocolate brown eyes, frightened as she run from those who were following her. She turned to the corner and found herself with nowhere to go. She had no choice now but to face the ones she was running from.

She stared at the eyes of her own flesh and blood, the eyes of her enemy, and the black eyes of her own beloved sister. She's cornered and there is no escape, no way could she live through it. She had her back on the wall as she raised her wand to her enemies. They laughed at her frail demeanor and the black-haired woman stepped forward and tortured her. The girl couldn't fight back.

She screamed and tossed on the ground as she felt the curse touch her. The dark cloaked figures laughed at her weakness, though a muffled sob can be faintly heard by the rest. The woman in front pulled downed her hood, freeing her crazy black hair. She stared with cold black bloodshot eyes at the girl, who she knew once to be her sister.

"Isabella, join us and you'll be spared," she offered unsympathetically. But her eyes were begging for her to see the reason of this offer, even though her voice came out icily. But the girl did no inclination of acknowledgement or agreement. "Fine," the woman scoffed at her, "You have to die then," she stated, pointing her wand at the girl.

There was a crying woman who came over and held on to her arm, restraining her from killing. "You can't Bella! She's our sister!" she screamed in fright and anxiety. The woman shrugged the hand off and turned to her, displeased. The woman, Bella, stared at her favorite sister disapprovingly. Before turning to the scrawny limp girl on the floor, she whispered, "She isn't anymore, Cissy." The other woman gasped at the coldness of her voice.

Before anyone could even say a word, the woman already shouted, "Avada Kedevra!"

Chapter 1: Acceptance and Deception

One fateful night at the House of Druella and Cygnus Black, one little girl, whose black hair curls down to the middle of her back, bounces up in down with the letter on her hands. She quickly made her way to her sister to brag her acceptance.

"Isa! Isa! Did you receive your letter? Did you? Did you?" Bellatrix kept jumping on her bed, trying to wake the sleeping form of her beloved twin. Isabella stirred and removed the covers that was covering her face and glared at her sister. She caught sight of the clock that is positioned above the bathroom door to which her bed is facing.

Isabella sat up against her will, her hair splattered across her face as her chocolate brown eyes dropped every once in a while. "Bella, it's three in the morning, can you please let me sleep?" she pleaded, hiding under the covers once again. The shaking of the bed stopped as Bellatrix jumped off the bed to sit on her own bed, which is just beside Isa's. She stared at her sister as she pondered about her response.

"Fine," she scoffed, thoroughly irritated with her sister's lack of interest. "You're just scared that you'd be the squib of the family," she stated, wondering about the odds of it coming true. She always questioned why her sister hasn't showed any signs of magic coming off her unlike her. But she shrugs it off every time.

Isabella shoved the covers away, surprised and scared at the possibilities. "I am not a SQUIB!" she screamed. Her whole framed shook from the image of her father and mother disowning her if she happens to be magicless. You worthless waste of money, you should be more like your sister, she imagined her father's voice shouting as he orders the house-elf to punish her.

Bellatrix cocked her head to the side, disbelieving. "Then why haven't you received your letter yet?" she asked, completely doubtful and mocking. She got her letter not awhile ago and was wondering why her sister hasn't had hers yet. They were supposed to come at the same time, weren't they? She asked herself. The only rational—or the one she believed to be the reason is that her twin is a squib, which she wouldn't be surprised to know.

Isabella coughed, claiming her sister's attention once again. "You received yours already?" she asked as she released a huge yawn. She scratched her head and stretched her arms afterwards. They went out yesterday with their mother to shop for clothing and she was extremely tired.

Bella rolled her eyes at the obvious question "Naturally," she answered, haughtily.

Isabella thought about it. "What does it say?" she asked in a small voice. She was completely interested but she, too, is scared to believe that she is magicless. She would be a family shame if it does happen. Her older sisters, Meda and Cissy were both in Slytherin, like the rest of the family. They were both in good terms with the rest of the pureblood society. They aren't worthless like she is. They were both excellent students and mom and dad are proud of them. So it meant that much was expected from her and her twin.

Bellatrix gave her a smug smile. "That I've been accepted of course!" she exclaimed proudly as she looked at her sister's discomfort. She always likes to be above her more than anyone else. She is completely aware that since she has a twin, they're always compared to each other and she's pleased to say that she always turns out to be the best.

Isabella is also informed of that fact due to her perceptiveness. She doesn't mind that her twin receives all the attention, she didn't want it anyway. She also knows that her sister wanted the attention. Therefore, she's glad for her. Though that wasn't what Bella has in mind.

She's jealous, Bella thought as she stared at her sister. She liked the thought and smiled smugly. She likes it when she's the one adored, the one loved most of all. She likes to be the one always noticed, the one who always gets first, and the one who gets the best. And she doesn't know that Isabella doesn't really wants anything material or selfish. She just wanted to make her parents happy and everyone she loves to be happy, which includes her twin.

"Do you think I'd get mine?" Isa asked nervously as she fuddled with the lock of her hair. What if I am a squib? What would I do? What would they do to me? Would they still want me? Those were the question she has in mind. She was scared that she'll be like her cousin, Sirius Black. He is older than her by a year and he got disowned by his parents. He's just twelve, Isabella thought.

Isabella was anxiously waiting for Bellatrix to reply and so she did. "Of course, you would!" Bella quickly lied and her sister quickly believed her. She doesn't really want that. But she doesn't really want to hurt her by her words so she pretended to be optimistic. She actually cared for her sister, but she cared more for herself.

They were both startled when their bedroom door suddenly opened, revealing their eldest sister in her pajamas, looking at them reproachfully. "Bella, Isa, what are two you doing up early in the morning?" she asked disapprovingly. Bella instantly lightened at the sight of her and rushed over quickly. She grabbed the crumpled paper from her pajama pocket and showed it to her sister.

"I received my acceptance letter look! There's the school stamp! Do you see it?" Bella gushed and exclaimed as she jumped up and down with excitement over pouring her. Meda didn't look interested as she looked over the letter in front of her face.

"Yes, Bella, I see it," she dismissed hastily and gestured for her to go back to bed. Bella obliged against her will, muttering words that she wouldn't let her sister to hear. Meda heard otherwise, but ignored it. "You two better sleep now, before mom and dad catch you two awake," she warned and closed the lights off.

"Okay!" Bella exclaimed as Isa simply nodded. The door closed and it all went silent. Sleep finally got to Bella as she lightly snored in her bed. Isa on the other hand can't get herself to sleep. She sneaked out of her room and went to her sister. She stood by the door, contemplating whether or not she should do it. In the end, she just wanted to get over it.

"Meda?" she asked as she slowly opened the door. She saw her sister completely engaged in reading her muggle book. She kept it as a secret from her parents and only reads when they're asleep or when she's at school. She's in fifth year, while Cissy is in third year. They're both in Slytherin just as their parents wanted.

"Yes, Isa?" she looked up from her book. "Come here," she said as she placed the book back on the nightstand and opened her arms wide for Isa to snuggle on. Isa relax on the embrace and stayed there for quite awhile before finally getting the courage to ask the question that had been mugging her.

"Do you think I'm going to be accepted to Hogwarts?" she asked in a small voice that squeaked at the end as she fought a sob.

Andromeda pulled away and held Isabella on the shoulders so she can look straight in her eyes. "Of course, why wouldn't you be?" Meda asked in surprise. She didn't expect this kind of question. She looked at her little sister questioningly and Isa shrunk in her gaze. She buried herself at the crook of her neck and sighed in despair.

"Bella said I'm a squib," she whispered, Meda heard her and didn't appear surprised. She knew that it has somehow to do with Bella. It was always the case. Bella this, Bella that. It was about time she questions these acts of favoritism that their parents does. Meda truly understood her sister since she had gone through that stage back when she was younger. But in her case, it was much worst. In due time, she just learned not to care about it.

There was a large amount of silence and Isa quickly concluded it was true and broke into tears. Meda panicked and rubbed her crying sister's back in soothing circles. "That is not true, Isa, don't believe anything Bella says, okay?" she placated her as Isabella cried on her shoulder.

"But I have no letters," she complained, still crying.

Meda sighed in frustration and Isa looked at her questioningly. Meda gave her a small smile and said, "That is not true, I saw your letter at the kitchen aisle when I went down to get some water," she said it as softly and as believable as possible. It was true though, but knowing Isa, she wouldn't believe it without proof.

"Really?" Isabella asked in awe. Her thoughts were relieved and happy that she was proven not to be a squib since no squib ever gets an acceptance to Hogwarts. She wondered off to a lot of possibilities on how her parents would react on this news. Isa, I know you'd be accepted, she imagined her mother's voice as she hugged her small frame as tightly as can be.

Meda smiled at the relief in her beloved sister's face. "Yes, of course, why would I lie to you?" she asked with a small laugh.

"I don't know," she whispered honestly, drying off her tears. Meda secretly smiled as she kissed her sister's forehead and sighed. "Can I sleep here? I can't sleep on my bed," Isa asked, completely sheepish as she admitted her sleep deprivation. Meda gave her a small but genuine smile and nodded.

"Of course," Meda answered automatically, more than happy to say yes. She made room for Isabella on her right side and tucked her in beneath the covers. She smiled at the memories that came to her. She remembered that she used to be the one to get her to sleep when she is crying. Even mother can't do it the way she does. Cissy doesn't really like babysitting, but when she has to she does it to Bella. Meda is always the one on Isabella's side and she couldn't be any happier to make her sister happy.

Unknown to both siblings inside the room that just right outside the partially open door, eavesdrops the small black-haired girl, who listened in the whole conversation. She hated the way Meda favors Isabella over her, making her hate her twin as well. She's not used to being unloved by anyone and that someone being her sister made her feel much worse. She quickly decided to make her way down stairs to go see it there is a letter on the kitchen counter...

And if there is, it has to remain undiscovered by their parents.

A/N: Tell me what you think please. Do you suppose I should call Isabella as Isa? Arielle? Marielle? Or do you have any nickname suggestions? Please do tell. I'd love to know what you think is best, because...some of you could be confused of Bellatrix and Isabella so we can change their nicknames to something much more identifiable. You could give nicknames for Bellatrix too if you want. I'll also answer your questions if you have one.

There's a poll on my profile please check it out. Thanks.

Anyways, review :)
