Summary: Derek had two sisters: Laura and Eve. He also had a brother: Jeff. Check out their life before the fire.

Sister of mine:

Chapter one:

Victoria Hale smiled as she held her new daughter in her arms, cradling her as she watched her other children. Her seven-year-old Laura sat drawing with her tongue poked out, while her two sons, five year old Derek and ten year old Jeff wrestling playfully on the wooden floorboards.

Victoria was happy with her family now. Herself, husband, Brad, two sons, and two daughters, that lived in the Hale family home. The Hales' were a big family; Brad had four sisters and two brothers, all of them living under one roof as the pack.

"Dinner's ready!" Olivia, Victoria's sister in law screamed from the kitchen, and everyone besides Victoria and Eve piled into the dining room to eat.

Finally, peace and quiet, Victoria thought. Ever since Victoria had had the new baby, she hadn't been able to have time to herself. Even thought this time wasn't exactly to herself, she was still happy and joyful that it was peaceful and Eve wasn't crying.

Her husband and werewolf, Brad, was the father to her kids. They had taken his height, his face shape and his skin. Laura had his eyes and hair, light brown hair, long like her mom's, and dark brown eyes. So had Jeff. But Derek and newly born Eve were like her. Black hair, and green eyes, dark eyebrows and pale skin.

She loved her children deeply. But someday, they would become the curse of the Hales. Lycanthropy. She knew that in a couple of years time, and the full moon came about, Jeff would be howling and growing fangs like his father, his uncle Peter and David, and his four aunts. And then Laura would follow. And then Derek….And then Eve.

"Mama?" She looked over to Derek who stood in the doorway. "Can I play with E?"

Derek had adapted the name of his little sister when he figured out he couldn't really say her name with his two front teeth missing. Oh, how cute he looked, Victoria thought, as she nodded and he came forwards. But before he could reach her, she stopped him.

"Did you eat all your dinner?" She asked him. He nodded. "Did you?"

"I swear I did, Mama!" He exclaimed. "And Aunty Olive offered me ice cream and you know what I said? No!"

Victoria smiled. "Lay down on the carpet then. Eve can sit up and you can play with her. But careful please, sweetie."

After checking with Olivia if he had in fact eating all his dinner in a vast amount of minutes, and finishing before his older brother and sister, Derek played with Eve while Peter kept an eye on the two. Victoria went to grab some food from the kitchen for herself so she could eat.

In the living room, Peter and Derek were both lay on their stomachs as was Eve, and they were wiggling their legs and clapping their hands like her. Peter was Derek's favourite uncle, and always told Derek fascinating stories that would entertain him to no end.

Victoria wasn't expecting what was going on when she walked back in the room. All she saw was her daughter acting like she was supposed to—a baby—and Peter wiggling on the floor, and clapping his hands, like her son. She rolled her eyes, and left them to it. That's how it went in the Hale house.

Brad walked in through the front door to see Peter and Derek still dancing and wiggling with Eve on the floor. Like his wife, he rolled his eyes and walked into the kitchen, laughing. It was just his wife in the kitchen now, as Laura and Jeff were outside throwing a ball back and forth, and the rest of the family were doing their own thing else were.

He wrapped his arms around his wife's waist and snuggled her close to him, giving her a kiss on the top of her head. She smiled in content, and sighed happily.

"Good evening, love," He greeted her.

"You sure are in a happy mood," Victoria said.

"Why shouldn't I be?" He asked, tightening his arms around her waist. "I've got a lovely new born baby, three other kids and a gorgeous wife."

"Mm," Victoria replied. "I like I when you're happy. But let's not get too happy. Eve was conceived when you were happy."

As if she heard her name, Eve started to cry in the other room.

"Peter's probably scared her," Brad sighed, shaking his head. "I'm on it!"

He dashed out the room faster then she could blink. Victoria sighed. Life was great.

(FIVE YEARS LATER)

"Jeffrey! GET UP!" Victoria screamed up the stairs again.

Eve toddled along the hallway towards where her older brother's room was, and tapped her little knuckle against the hard wood of the door.

"What?" A voice shouted at her.

"It's Eve," She said happily.

Movement came behind the door before it was swung open. Jeff was standing there, rubbing his eyes sleepily. He smiled as he saw Eve looking up at him smiling. He picked her up, and held her to his hip.

"Mama's gonna get very mad, Jeff, if you don't get up," She said to him, frowning slightly.

Jeff smirked. "I'm up. Go tell her Jeff's up and he asked for pancakes."

"Derek's having pancakes as well!" Eve said.

Jeff put her down and she toddled towards the top of the stairs. There, she just stood. She didn't like going down the stairs on her own, afraid. So when she saw her twenty two year old cousin, Liam, walking towards her, she smiled happily.

"Liam?" She called to him as he was about to walk into the bathroom. He turned and looked at her. "Can you give me a lift down the stairs?"

In a minute, Eve was sat on the wooden bench at the table by her other older brother, Derek, who was eating his syrup covered pancakes and drawing a picture.

"Hey, Der," She greeted, smiling.

"E," he said back.

"What you drawed?" Eve asked cutely.

"You," He admitted, "Look, it's us as a family."

Eve looked awefully at the picture of stick men and stick women outside a very large house. "This is a weally good picture, Der."

"Thanks, E."

"Oh, MAMA!" Eve shouted to her mom who was working on the pancakes.

"Eve, no shouting," Her mom scalded. "What is it, sweetie?"

"Jeff wants pancakes like Der," She answered, "Can I have pancakes too, Mama?"

Victoria smiled. "You can have whatever you wish, darling. The choice is yours."

"I'm gonna ask Dada for a puppy!" She squealed and ran away. A few minutes later, she had a frown on her face, as she stomped in unhappily. "Dada said no."

"Laura asked him as well," Derek said, "He said no then too. Don't worry. When you grown older, and have your own big house and lots of babies, I'll buy you a puppy."

Eve smiled a gappy smile at him. "Der, you're the best big brother ever!"

Victoria smiled as her children embraced, and she snapped a picture before they stopped and went to do their own thing. Her smile fell, however, when she saw Laura standing by the front door, shouting.

"Ugh, why are you so god damn annoying?!" She screamed at Jeff as he ruffled her hair. "I thought you would learn by now that nobody likes you, and to leave them alone so they don't have to suffer."

"Thanks, Laura," Jeff replied, "Great to bond with you."

"Laura!" Victoria yelled cross, "Jeff!"

Both teenagers lifted their heads to their mother, and slumped into the kitchen to sit at the little table opposite their little brother and sister. They frowned when they saw Derek and Eve smiling at one another with sibling love in their eyes. Why couldn't they have that? Jeff and Laura had always been arguing with one another as soon as Laura could argue back. Laura was sure that Derek and Eve had about two or three arguments over petty things such as pens and teddies.

Victoria cooked all of them pancakes, put the plate down on the table, placed all the washing up in the sink for Olive to do, and then went on her way out of the door so she could go to work. Brad was taking Jeff, Laura and Derek to school and take Eve to kindergarten.

Laura poked Jeff rudely in the arm with her fork. "That was for ruffling my hair earlier, idiot."

Eve gasped very five year old like. "You just said a bad word, Laura."

"So?" Laura snapped. She rose from her chair and walked towards her bag that was hanging on the hooks by the front door. "I'm going to pack my bag. Alone."

Jeff flinched when Laura's door slammed shut, and noticed Eve's wide eyes. "It's okay, Evey, she didn't mean to snap at you. Laura's just having trouble with...school."

"Oh," Eve said and smiled. "I'll asked her if she's okay."

"No!" Jeff said quickly. "She doesn't like it brought up. So leave it, Eve."

"Oh," Eve said again, smiling. "Okay."

Eve smiled happily as the rest of her siblings glared at her from the back seat. Laura's legs were getting crushed behind her dad's seat, as he had his seat way back because of his long legs. She hated her dad's car. She had begged for him to get a new one, but her answer began with an f, and end in off.

They pulled into the parking lot of the high school, Jeff climbed out and slammed the door, leaving his dad, Laura, Derek and Eve sitting watching him go.

"Der and Lar to school now, Dada," Eve said. Brad nodded. "And then me!"

"Yep," Derek said.

"I get to see Scott and Stiles!" She squealed loudly.

Brad frowned. "The sheriff's kid?"

Eve nodded. "Yay!"

Eve smiled as Scott and Stiles ran up to her, and greeted her with hugs. Brad held on to his daughter's hand as she was getting hugged, frowning at the boys who were hugging her daughter. The sheriff and his wife came up to them as did another couple. Brad's frown was lost.

"Hi," The woman from the other couple said. "I'm Melissa McCall, and this is my husband Paul McCall. Our son's Scott."

"Hey," Brad said, "I'm Victoria's husband. This is a one off. I'm usually at work."

"I'm John Stilinski," the sheriff said, "This is my wife, Sarah. Our son's Stiles."

"Nice to meet you," He said politely. He checked his watch. "Oh, crap. I've gotta run." He bent down to Eve's level and kissed her cheek. "I love you, honey, have a good day at school. Mama will pick you up, okay?" He looked up at Melissa. "Could you watch her for me? I have to run to work."

Melissa nodded, waving it off. "It's fine. Go."

"Thanks," He said, "It was great meeting you all."

"You too," They all chorused.

Eve smiled in happiness as she led on her bed in the room she shared with her seven year old cousin, Amy. She was gonna go to sleep, and then have another great day tomorrow, like she always did. But about ten minutes later, the five year old was still awake and tossing and turning. So she climbed out of her bed, and made her way to Derek's room.

Derek was led in his bed, looking at the ceiling. She jumped up on the four poster bed and snuggled into his side, smiling.

"Hey, Der," She said softly.

"E?" He asked, "What are you doing in my room?"

"I can't sleep," She replied sleepily.

"Oh. Goodnight then, E."

"Night, Der..."

He smiled happily when he heard her little snores. He fell asleep himself, under the full moon.

Victoria started to panic when she didn't see Eve in her bed. She looked in all the rooms until she checked Derek's room. She sighed and looked at the two siblings who were lying in the bed, curled up to one another. She took a picture, before walking out quietly and sighing in relief.

Her husband was busy helping Jeff with his shifts, and Laura was also having help by her aunts. It was dangerous for Victoria to be around new wolves on a full moon, because they could kill her, even if it was her daughter and son. So, she was on her own, watching a movie before falling asleep.

"Derek! Eve!" Victoria screamed out into the forest. "DEREK! EVE!"

"Honey?" Brad asked.

Victoria had gone into Derek's room as soon as Brad had come home, to find Eve and Derek both not in Derek's bed.

"Brad, they aren't here," Victoria continued panicking. "I don't know where they are-"

"Shh," Brad cut her off. "I can hear them. They are in the water."

The parents walked towards the lake that was a little way from the Hale house. And there, Victoria saw Derek and Eve playing around in the water, Derek taking great care of his sister. Brad smiled at the sight of them, but Victoria was beyond angry.

"DEREK AND EVELYN HALE, WHAT THE HELL DO YOU THINK YOU'RE PLAYING AT?" She screamed.

Both children spun around and saw their mother. Oh, no...

Now, this was just an idea. Don't know whether to continue, but if you want me to, tell me;D REVIEW:D
