Killer Instinct

Chapter 1: Ripped Away

A/N: We all know about how Courtney's life changed after she made the fateful switch with her sister, but what about Alison's life? This story talks about what Ali went through and how she got her revenge on not only her sister but her sister's best friends. I figured it was time to do a story like this since the Pretty Little Liars book series has officially ended and Ali's story was never really delved into, so that's what this story is about. I hope you enjoy it.

Disclaimer: Pretty Little Liars and all characters are property of Sara Shepard. I only own the plot and nothing more.

Summary: Alison DiLaurentis had everything she wanted until it was taken away. Now all she wants is a chance to get her life back and to make those who did this pay for what they've done.

Have you ever had something really unfair happen to you, something that you just couldn't believe was happening? Like that time your little sister broke your mom's antique vase and blamed it on you, causing you to get in trouble? Or how about that time the school bully accused you of copying off her paper which made the teacher give you a detention and a failing grade instead of her? Haven't you ever wanted to get them back for it?

Well, in Rosewood, something unfair did happen to a certain beautiful girl, and it would cause her to think of nothing but getting back those who had wronged her.

Alison DiLaurentis was in the kitchen with her brother Jason, frantically looking for her initial ring. It was very precious to her, and she was upset that she couldn't find it. While she was looking for it, her twin sister, Courtney, came downstairs dressed in the same clothes she was in. Ali hated it when Courtney dressed like her. It was so annoying. She made an annoyed sound as she opened a drawer and her ring wasn't there.

"What's wrong, Alison?" Mrs. DiLaurentis asked her daughter.

"I can't find my ring," Ali complained.

"What ring?" her mother asked.

"My A is for Ali ring," she answered. "I know I had it, but I can't find it now." She turned to her brother, Jason. "I bet you took it, didn't you?"

"Why would I take your ring?" Jason asked her.

"Because you're sneaky," she replied. "Just like you took my piece of the Time Capsule Flag, too."

"I didn't take that, but even if I did, it wouldn't matter," Jason told her. "Stealing evens out the playing field, remember?"

Ali rolled her eyes and turned to her twin sister. "Cute shirt, but you need to change it," she said. "I'm having déjà vu."

"I like this color on me," Courtney replied.

"Yeah, right," Ali scoffed. She sauntered over and took a doughnut from the box that was sitting on the counter.

"Careful, Ali, doughnuts will make you fat," Courtney taunted.

"So will mental hospital food, schizo," Ali teased back.

Courtney glared at her, a tinge coming to her cheeks. Ali loved teasing her sister about being in a mental hospital, and she knew how sensitive her sister was about the subject. "You know what? I do know where your Time Capsule flag is," she said. "I took it and then gave it to Jason, but he'll never give it to you."

Rage filled Ali. "I knew it!" she yelled. "Give it back!" She saw the fabric peeking out of Jason's pocket and pulled it out, noticing a wishing well had been drawn on the flag. She turned to her sister.

"Did you draw this?" she demanded.

"Yeah, but who cares?" Courtney asked her.

"You had no right to do that!" Ali snarled. "I told Mom you threatened me, and that's why you're going away again.

"I didn't do anything to you!" Courtney protested.

"It doesn't matter. You're not welcome here, bitch."

"Don't!" Courtney yelled.

"Don't!" mimicked Ali.

"Stop it!" cried Courtney.

"Stop it!" imitated Ali.

"That's enough!" Jason yelled.

"That's enough!" imitated Ali. Then she pushed Jason so that he hit one of their cabinets, causing a dish to shatter. Rolling her eyes, Ali left to go to the bathroom.

"Why did you have to start with her?" she heard Jason chastise Courtney.

"I didn't mean to," Courtney protested.

"Yes, you did," said Jason.

Ali rolled her eyes again. At least Courtney would be out of her life soon, and that was something she could look forward to. She left the bathroom and saw her mom in the hallway.

"We're leaving, Courtney," her mother said briskly.

Ali's eyes widened. "Mom, I'm not Courtney," she said. "I'm Ali."

Mrs. DiLaurentis sighed. "Now, don't start that again," she warned. "You're going whether you like it or not."

"But, Mom, I'm Ali," Ali protested. "Courtney's somewhere else."

Her mother didn't listen and ushered Ali to the car. She struggled and kept yelling, "I'm Ali! Why won't you listen to me? I'm Ali!" Her father shoved her in the car, and off they went.

Ali was pissed off. Her sister was such a bitch and she was going to pay for what she did. There was no way she was getting away with this.

A/N: A little short, I know, but I felt this was a good place to end this chapter. I'm so excited for this story and can't wait to write more. Please feel free to leave a review and have a shelltastic day.
