DISCLAIMER: I own nothing~ JKR = BOSS.
I don't think Bellatrix was always so bad, because she seemed to really care about and love Narcissa. That being said, I think that when they were younger, the three sisters were close. This is what I think happened...
Oh btw, I liked Narcissa's hair in the books, but also in the movies (though I'll admit I liked it better in DH than in HBP). So I imagined she was born with it being black and blonde. Sorry if you prefer it simply blonde...*
Chapter 1: At Least We Had Each Other
"Bellatrix... Bella.. Sweet Bella... My Bella..."
A mysterious voice called out to Bellatrix Black. She was walking barefoot in a misty forest, dressed in an emerald halter dress. Butterflies glowed in vibrant colours, leaving slightly faded trails as they fluttered around the dark forest. The voice. She had to find it.
"Bella, come. Come to me..." it coaxed.
"Where are you?" Bellatrix called out.
Suddenly, a strong force enveloped her. She felt it pulling her body like a magnet. The Voice was close. She was getting closer.
"Bella~" another voice called to her.
This one was softer and harmonious. It seemed to sing to her instead of speak. Then Bellatrix came to the point where she knew it was all just a dream. But she fought to listen to the mysterious voice and ignore the harmonious one. Unfortunately, Bellatrix was beginning to wake. The harmonious voice became more clear and Bellatrix could feel someone shaking her.
"Bella!"
"Argh...whaaat?" growled Bellatrix.
The eldest Black sat up abruptly, running a hand through her wild, wavy hair to get a good look at who had disturbed her blissful slumber. It was, of course, Narcissa Black. She was wearing her favourite cotton pink nightgown with her soft black and blonde hair* pulled into a ponytail.
"You-You were doing it again," said Narcissa, a bit shaken by her sister's reaction, "You were talking in your sleep."
"So? It's nothing you need to be worried about," spat Bellatrix, flopping back onto her soft, fluffy pillows.
Narcissa shrugged, "But it's not the talking part that's odd. It's what you're saying."
Bellatrix raised an eyebrow in uncertainty, "And what, pray tell, was I saying?"
"It sounded like you were looking for someone. Like this," Narcissa shifted and imitated Bellatrix's sleep-talking, "'Where are you? I can hear you but I can't find you?'...Like that."
"I don't talk like that!" protested Bellatrix.
"Do too."
"Do not."
"Do too."
"Do NOT."
"Do to-AH! AHAHA, BELLA, STOP!"
Bellatrix had tackled her baby sister and started tickling her ruthlessly. Narcissa was red in the face from laughing. Her stomach hurt and so did her sides. No matter how much she begged, Bellatrix didn't stop...until she started laughing herself.
Narcissa tried to catch her breath and rubbed her stomach, only turning her head to watch her sister laugh hysterically.
"Oh! Oh! Ahahaha!" laughed Bellatrix, "Oh, that gets me every time!"
She gasped for air and looked at her sister, "The way your face turns as red as an apple! And your laugh-AHAHAHA!"
Suddenly, the middle Black sister entered the room. Her golden brown hair all tangled and messy. Out of the three of them, she was the only one that moved around in her sleep.
"Ergh...will you two hold it down? A girl can't get any sleep around here with you lot screaming!" complained Andromeda.
Bellatrix scoffed, "Well! Look who woke up on the wrong side of the bed!"
"Literally," added Narcissa.
"Try on the floor," muttered Andromeda as she walked over to her sister's bed and plopped onto it, face-down.
"Ooh. Ouch," said Narcissa, sitting up and examining her sister's legs and arms, "Well, at least you didn't bruise yourself this time."
"Luckily!" said Andromeda's muffled voice.
"Weird one, you are," said Bellatrix, "At least you don't sleepwalk."
She messed up her sister's hair even more. Now it resembled an afro. Bellatrix bursted out laughing. Andromeda lifted her head to glare up at her older sister, which only resulted in more laughter.
"You-Your faaaceee!" laughed Bellatrix.
Once Narcissa saw Andromeda's face she started laughing, too.
"Oh my gosh! You look like Aunt Walburga!" she snorted.
"Oh, merlin! Cissy, stop! I'm dying!" said Bellatrix.
Andromeda pouted, "Stop that! It's not funny!"
Bellatrix stumbled out of bed and dragged her sister to the mirror, Narcissa followed. When Andromeda saw her appearance she almost fell down laughing.
"Blimey! I look ridiculous!" she laughed.
The melodious sound of their laughter was halted by their father.
"What is going on here?" he demanded.
"F-Father!" gasped Narcissa.
Bella and Andromeda ceased their mirth and faced their father. Cygnus frowned at the disheveled sight of his second-born daughter.
"Good blood, Andromeda," he said, hands on his hips, "Don't you brush your hair anymore?"
"Uh...I-I just woke up, Father," said Andromeda, gently elbowing her sisters to stop them from laughing.
"Right, well, go make yourself presentable. I can't have our guests thinking my daughters are untidy," said Cygnus.
"Guests? Who's coming, Father?" asked Narcissa.
"The Lestrange family," said Cygnus, "Your sister is seventeen, which means she is to be married within three years."
"Why three?" asked Narcissa.
"Oh, enough questions, Narcissa! Now go on! Get yourselves ready! And Bellatrix, your mother wants to remind you that you are to wear the dress she picked out," said Cygnus.
"But Father I-" Bellatrix began to protest.
"Bellatrix, please!" said Cygnus, slightly raising his voice, "Don't argue."
With that, he left his three daughters in an awkward atmosphere.
"Why do you have to get married within three years, Bella?" asked Narcissa.
"Every pure-blood girl is to be wed by the time they're twenty because that's just how it is," explained Bellatrix, taking the pink dress from her walk-in closet and giving it a disgusted look.
"It's one of their sacred rituals," said Andromeda, mockingly, fluttering her fingers and rolling her eyes.
The youngest black frowned. The idea seemed to bother her. Narcissa was a very inquisitive girl at 13. She always wanted to know everything and often tagged along with their mother at gatherings to listen in on the adults' conversations. Bellatrix knew she was going to be an active socialite just like Druella when she grew up.
Andromeda on the other hand, wasn't at all interested in the world of the pure-blood society, but more in the one outside of it. She was always out and about; merlin-knows-where, doing merlin-knows-what. Bella and Cissa didn't see that much of their 15-year-old sister because of this. Which was both a good and bad thing. Whenever Andy was at home, it only meant yelling, screaming, crying, and headaches for them. Of the three sisters, Andromeda was the one that never got along well with their parents.
As for Bellatrix, it went both ways. There were times when she got along very well with her parents, but other times when Andy and Cissa had to distract her so she wouldn't hex their overbearing arses.
That's how it was with the Black sisters. If one of them got into trouble, the other two would always share the blame and consequences. They only had each other, after all. At least they had each other. So they made it a point to always stick together. No matter what, they would care for, protect and love each other. Because no one else would.
"What's wrong, Cissy?" asked Andromeda.
"What if I don't get married before I'm twenty?" said Narcissa, "Or what if I have to marry someone I don't love or he doesn't love me? Or what if he's cruel to me?"
"Oh, don't think about those things! Look at yourself! You're gorgeous, sweet, and fun! No man will be able to resist you, especially when you get older," said Andromeda.
"Andy's right, Cissy. And if any fool tries to harm you in any way," said Bellatrix, "He'll answer to me."
She looked down at Andromeda who was lying on her stomach on the bed, her hair still messy.
Bella giggled and handed her a brush, "That goes for you too, Aunt Walburga."
Andromeda beamed and went over to the vanity.
"Really, Bella? You'd do that for us?" said Narcissa.
"Of course! Anything a man can do, I can do even better!" said Bellatrix, proudly, "And besides, I'm your big sister. It's my job to protect you two freaks."
Narcissa and Andromeda sandwiched their sister in a hug. Bella wrapped her arms around them. Although she rarely said it, she loved her sisters more than anything in the whole world.
Well, them and him...
