There was not a single boy's eye in all of Beacon Hills High School that wasn't staring at Arielle McCall when she strutted into school the first thing Monday morning. With her black leather jacket, ripped white shirt, black shorts, ripped tights, and combat boots, who wouldn't be staring at her? Even Stiles had to stop himself from turning to look at her, for fear of doing something he'd regret.

By the time the school day had ended, Arielle knew who would be the target of her desires. So she pulled an old friend, Aiden, into an office and started kissing him ferociously.

"Whoa, whoa," Aiden gasped, grabbing onto her jacket, "What's this about? Is this about Stiles?"

She shrugged, "So what if it is? It's been a while anyway and I need to forget about him," she brought her lips towards his again, but he backed up, so she groaned, "Look, I haven't had sex in weeks. Are you going to help me out or am I going to have to take care of my needs myself?"

Aiden's eyes grew wide as he looked at her chocolate brown eyes, looking at how her body moved beneath her new wardrobe. Suddenly, he brought his lips to hers, picking her up and wrapping her legs around his waist and setting her down on the desk. She laid down beneath him and he attached his lips to her neck, his hand feeling the skin beneath her shirt.

"You should know," Arielle gasped, "I'm only going to keep this up until I find somebody better..."

When she moaned and sat up, grinding her body against his, he started to growl aggressively, kissing up her jawline until his lips met her ear.

"I don't give a fuck..." he whispered, his hands finding a way underneath her shorts.

After that afternoon in the room with Aiden, Arielle would often bring him home most nights when her parents weren't at home. They would do the usual, and then he'd leave. Neither of them were upset with the arrangement, and neither of them were looking for anything more than sex. He agreed to take her to the prom only if she'd put out, and she hadn't given him any sign that she wouldn't.

One night, after Aiden left the house with nothing on but his jeans and a smile on his face, Scott had come home from Stiles's house a little bit early and decided to figure out what was going on. He barged into Arielle's room, seeing her sheets an absolute mess, her hair tied up in a ponytail and her, wearing nothing but a big t-shirt.

"Arielle," Scott said, "What are you doing to yourself?"

"It's more like, what is he doing to me," she giggled, looking at herself in the mirror.

"No, I mean it, Arielle," Scott said angrily, "What's going on? One minute you're your usual self, now you're dressing differently, sleeping around-."

"Hey, if I were sleeping around, different guys would be leaving here each night," Arielle shrugged.

"You know what I mean," Scott sighed, "I just wanna know if you're okay, you know? I'm your big brother and I'm concerned. I don't know if you're doing this because you're hurt or if you're angry or upset about anything. We don't talk much nowadays and I feel like I'm missing something from you."

"Well you're not," she shrugged, "I'm fine. Everything is fine."

"Are you sure?" Scott asked again, "Because you're not sitting with me at lunch anymore. Did I do something wrong?"

"Scott," she sighed, "Calm down. It's not you. Honestly."

"Arielle, you're my sister," he pried, "I know you better than that. Something is wrong and you're going to tell me."

Arielle banged her hand on the table and sat back in her chair.

"God dammit," Arielle spat, "Do you wanna know what's been wrong with me?! You really wanna know!? I fell in love with Stiles, THAT'S what happened!"

There was dead silence between them.

"I know..." Scott whispered.

"And it ruined me," Arielle continued, not hearing him, "I just wanted to protect him, but I loved him. The one time he decides to finally listen to my opinion, he chooses that the best way for us to stay apart is to break up, so that's what made me so miserable last-" she paused for a moment, "... did you just say... you know?"

Scott nodded, "Yeah... I found out on my own... and..." he took a deep breath, "I made Stiles break up with you... it wasn't because he doesn't love you or anything like that... if anything, he wants to be with you more than ever-."

"What?" Arielle breathed.

"I know what I did was bad, but I was just trying to-."

"Let me guess? Protect me? Isn't that what everyone wants to do nowadays? Let's all just protect Arielle and not let her have a life!"

"That's not what I meant-."

"You stand there and you insist on making sure that I'm okay. You see something wrong with me and your impulse is to fix it and yet you're the very reason why I am the way I am right now! This is your fault."

"I didn't think you'd react this way," Scott explained, "Please, just hear me out. You'll see I had good intensions."

"Yeah right," there was a pause, then Arielle looked at Scott, "Get. Out."

"Arielle-."

"Get out!" She picked up her hairbrush and Scott scooted out of the room and closed the door before the brush hit it and she screamed, falling into her bed and clutching onto the pillow. It seemed to be the only thing in the room that wasn't spinning.

Everything went dark. Arielle had cried herself to sleep that night and Scott simply stood by the door, trying to make up for the horrible thing that he did. It killed him to hear her sobs through the door and to feel her squirming in her bed as she tried to get herself to go to sleep. Eventually, however, he left. There was no mending the situation. There was no way Arielle was going to even consider forgiving him for a while.

As Arielle slept, clutching her sheets in her fists, she heard a faint voice in her dreams, whispering to her, like a siren.

"Listen to me..." it whispered, "Isn't this neat? Wouldn't you think my powers are complete? Wouldn't you think I'm the nymph who has everything?"

Arielle rolled over and threw crushed her pillow over the back of her head, but the voice didn't stop. It rang just as clearly as it did before.

"But who cares? No big deal... I want you..." it hissed, but it didn't stop there, "You wanna be where Stiles is. You wanna see him happy strolling around on the street. Come and find me Arielle. Down where I hide, down at the pool, down where I plot against you and your friends, wandering free. So come and join me. Be a part of my world... or suffer and be a part of HIS world."

The darkness in Arielle's dream was starting to be submerged in water, the bubbles rising as she got deeper and deeper into the water. Something was swimming towards her. It was a woman with long white hair and white skin with bright blue eyes. She stopped in front of Arielle and barred her teeth at her, then swam away, carrying Stiles behind her, who was lifeless and pale.

With a sharp gasp, Arielle woke up and it was still dark outside. The time read 2:30 am, but that didn't matter. What also didn't matter was how Arielle currently felt about her brother. Any ass-kicking that she needed to get done would simply have to be done at a different time. She knocked, fiercely and quickly, on Scott's door until he opened it, his eyes both dead and wide awake at the same time.

"Arielle," he breathed, "Are you-."

"Good, you're here," she sighed, then peeked her head into the room, "Where's Isaac?"

Scott looked behind him, "He was just..." the room was completely empty. Not a single soul was moving inside, not even in the bathroom, "here..."

"Get dressed," Arielle panicked, "We have to find him NOW."

"Whoa, whoa," Scott halted, "What's wrong?"

"I had a dream last night," Arielle explained, "The Nereid came to me in a dream and threatened me. She told me to go to down to a pool and find her or she'd start killing people. I think they took Isaac."

"In the middle of the night?" Scott asked.

Arielle nodded. At this moment in her life, Arielle didn't take much seriously anymore, but the look in her eyes that Scott saw when she believed that Isaac had been captured was something that, not even he, could defy. Scott nodded back and closed the door, quickly opening it a second later.

"Come on," he said, taking her arm, "We gotta go."

It was too much to sneak past their parents bedrooms at this hour without getting caught, so Scott ran to the window and hoisted his sister onto his back, then jumped out the window, landing square on his feet, then putting her down. The mere thought that Isaac, or even Stiles, could be hurt, was something that killed the both of them. At least they had that in common in order to do the one thing they do best; save their friends.
