Psychopath (Stiles AU)

Chapter 17

It would seem that the world slowed down as (Y/n) approached her family home. 

There was a missing person's poster taped to a tree outside the house, and the flowers had died, but otherwise it looked just as it did when she first left. Her beat up car was sitting in the drive way, the tire still not replaced yet. 

Slowly, she began to walk up the drive way until she came to the front door where she then hesitated. Did she just walk in? Knock? She hadn't been home in so long that it didn't feel like home anymore. It was more of a place that she had come to know of, not somewhere she'd spent her entire childhood. 

Finally, she decided on knocking. 

Her fist rose to tap three short knocks onto the wood, and her breath got caught in her throat when she heard her mother's voice called a simple 'coming!'. 

The door was suddenly tugged open, her mother standing there dressed in one of her beautiful bright yellow sun dresses. Her hair was pulled back into a messy pony tail, she looked like she was completely fine. Though when (Y/n) caught a glimpse of her tired eyes, she knew that she was far from okay. 

"(Y/n)...?" Her mother whispered, low as if she couldn't believe the sight in front of her. 

"Hi Mum." She smiled, and before she had the time to even blink her mother was crashing into her, engulfing her into a hug. Her mother's head was buried into her neck, tears staining her shirt. She pulled away from her mother's hold, sending her a watery smile. 

"W-Where have you been? Are you okay? Are you hurt?" 

Her father suddenly emerged from behind her mother, and for the first time in her life she saw her father begin to cry. He didn't make an attempt to hug her, though she knew he wouldn't. He was never much of an affectionate person, but to see him cry was enough to let her know that he was deeply worried about her, and relieved to see her again. 

"I'm fine, Mum, promise. I just... how about we talk inside? Its getting cold out here." 

Her mother nodded immediately, ushering her into the warm house and shutting the door behind them. Now she had some real explaining to do. 

☩  

"And they believed you?" Stiles questioned, a devious smile on his lips as he stared at (Y/n) sitting across from him on his bed. 

She nodded at the boy, "Mhm, all I had to do was say I needed time to clear my head and they were sold on the lie." 

"Didn't think you had it in you." Stiles confessed, and his words made her eyebrows furrow. 

"What? You didn't think I could lie to my parents? I can be bad too, you know." 

Stiles scoffed at her, shaking his head, "No, not you. You're too innocent to do such a thing." 

"I am not." She huffed, crossing her arms over her chest. 

"Prove it." 

"Fine," She sighed. "But how?" 

Stiles' eyes turned a darker shade of brown, one corner of his lips tugging up into a smirk, "I know just the thing." 

☩ 

 It was approximately an hour or so later when the front door was opening again, and at the sound (Y/n) climbed down from Stiles' bed and hurried down stairs to see what he could have possibly been doing. 

After their conversation earlier Stiles had rushed off without telling her where he was going, only saying that she'd be able to prove that she wasn't as weak as he thought when he returned. 

She shuffled over to the front door to see Stiles struggling to hold up a motionless girls' body. He readjusted his grip on her, hauling her up into a more comfortable grip. (Y/n)'s eyes widened, "Stiles? What's going on?" 

"You're proving to me that you aren't as innocent as I think." He grunted out, hauling the girl through the house, toward the basement. With the flick of his head, he urged (Y/n) to follow him, and although a part of her told her not to go down with him, she couldn't stop her feet from moving. 

By the time she got down into the basement, Stiles had already secured the girl to the chair and was hunched over his knives. (Y/n) swallowed hard, shuffling into the room. Surely he wasn't going to make her doing anything to the girl, right? 

"You're going to kill her." Stiles suddenly spoke, only confirming her thoughts as he turned around with a knife in his hands, holding it out for her. 

She shook her head, refusing to take the knife while taking a step away from the boy, "N-No!" 

Stiles wasn't taking no for an answer as he stalked over to her, roughly taking her hand in his and shoving the knife into her grip, "Yes, you are." 

Her hands began to shake as he placed a hand on the small of her back, urging her toward the still motionless girl. He wrapped his hand around hers, bringing the knife up to the girls neck. 

"It'll be easy," He whispered, voice slick with a menacing tone. "Just one slice of the knife and it'll be all over." 

She'd began to cry by now, eyes shut tight while she vigorously shook her head as Stiles made her press the blade to the girls neck. Gently, he guided the knife to one side before pressing it harshly into the girls' skin, and before (Y/n) had another chance to take another breath Stiles was dragging the knife back toward their bodies. 

Stiles dropped her hand, and the knife slipped down and clattered to the floor. Her hand was wet, and the thought of it being that girls blood sent a sick feeling to her stomach.

She just killed someone.
