Bloody Senior Year

Chapter Three: Bloody weakness

"A vampire? Are you sure?" Derek asked threateningly, intimidating the scared girl in front of him in the living room of the Hale house.

"Yes!" Lydia said, trembling and close to sobbing.

"Enough, Derek. You know she's right," Peter said from his armchair.

"But, it's impossible," the alpha said stubbornly.

"Yeah, I agree with Derek. She doesn't even remember anything," Scott said. "It could be the trauma."

"Vampires are the only ones that drink blood. Look at her neck," Peter commented with a creepy smile.

"What do you know about this?" his nephew asked.

"I've read about them in the Bestiary. It won't be easy to kill," Peter said.

"How come?" Isaac wondered out loud.

"Well, these creatures are faster than werewolves, they can compel their victims, erase their memories. However, they can't walk in the sun so the only attack at night," the older Hale said while the pack looked increasingly worried.

"Am I going to be a vampire?" Lydia asked suddenly still scared and nearly hysterical at the thought.

"No, in order to become one you have to drink vampire blood and die with it in your system," Peter said. "Although it would be interesting to see if you were immune to that as well…"

"How the fuck do we kill it?" Jackson exclaimed angrily.

"A wooden stake through the heart, decapitation and fire," Peter listed. "There's an herb called vervain that hurts them also."

"I'll ask Deaton tomorrow after school and we can kill it," Scott said.

"What if we end up needing to use mountain ash to trap it?" Erica said nervously. "Lydia isn't in her right mind. She can't do it."

"No way in hell! We don't need him!" exclaimed Jackson knowing exactly what the blonde girl was implying.

"We have no choice," Derek said after some thought. "That creature is in my territory and we need help. Isaac tomorrow you'll talk to him and demand his help," Derek ordered the curly hair werewolf

"For the time being, be wary of who you invite into your home," Peter said. "Vampires must be invited in."

"That was fun. Don't you think, love?"

"Kol, you don't have to ask. You know I love to hunt with you," Jeremy said, embracing his lover making the older vampire smile with blood-stained lips. A dead girl lay their feet with bite marks on each side of her neck

"Do you think that three dead people in one night will attract the attention of that pack of dogs?" Kol asked. Smiling, he grabbed his lover by the waist.

"Well, maybe not, we could keep hunting if we wanted. Rebekah is stealing from the blood bank as well," the brown eyed boy said. He kissed Kol on the lips.

"Actually, I think I have other things in my mind now," the older vampire responded. He kissed his lover in a hungry way. Moving at inhuman speed, Kol pressed Jeremy against the wall of the alley they were currently in.

-

The next day Isaac was waiting for the arrival of Stiles near the entrance of the school. To say that he was nervous would have been an understatement. He didn't know why Derek had told him to do this. Isaac was probably the last person Stiles would listen to. He'd always felt guilty about stealing the only friend the boy had.

In the past, Isaac had held on to the hugest crush on Stiles. Maybe it was still there. He wasn't sure. He knew it was hopeless though.

After a long ten minutes he finally spotted Stiles and Allison heading toward the door to enter the school. He situated himself right in the middle of their path.

"Move out of the way, mutt," Stiles said, his voice full of venom.

"Can we talk in private please?" Isaac asked. His eyes were begging.

"No" Allison answered

Stiles seemed amused and held a hand up. "It's okay, Allison. I can handle him."

"Are you sure, Stiles? I really don't think it's a good idea," the girl said nervously.

"Yeah, go ahead without me. I'll catch up." Allison lingered for a while and then shrugged and kept walking. "Alright, dog, to the locker rooms," Stiles ordered.

-

"Hey," said Scott. He appeared next to Allison's locker as if he'd been waiting for her to show up.

She slammed the door and groaned. Scott was her weakness and she couldn't be weak now. She had to get rid of him. "What now, Scott?" the girl asked, trying her best to sound irritated

"I want to know how you're doing?" the boy asked. The concern in his voice was making her heart break.

"How do you think I am, Scott?" she snapped. He flinched and she continued. "I need some space, alright. There's a lot I need to figure out. So stop stalking me."

"Can I at least walk you to class?" he asked.

Scott looked so hopeful that Allison couldn't bear to tell him no. "Whatever," she said. She turned and started walking quickly.

"Where are you living now?"

"With Stiles."

"How is he?" Scott asked.

"Well. He's sad and angry at you for ditch him for someone like Isaac and a pack of murderous wolves," she snapped. They both stopped walking.

"I said I was sorry," Scott said a little too loudly. People were looking at them.

"Scott, sometimes sorry doesn't cut it" she said. With that she walked away from her ex-boyfriend, trying to ignore how his heart his was beating so fast. She could not be weak.

-

"You look good," Isaac blurted out to Stiles, once they were in the empty locker rooms.

Stiles raised an eyebrow. "I know. Danny ask me out yesterday. Can you believe it? I would love to say yes but he only asked me because of my makeover and I don't like shallow people" Stiles changed the subject with an evil smile "Now, I know you didn't bring me here to give me compliments. Cut the crap and tell me what you want."

"Derek needs your help," Isaac explained. "Lydia was attacked yesterday by a vampire and we need you."

"Well, I would love to help," Stiles replied sarcastically. On a serious note, he added, "But I couldn't care less what happens to Lydia and I'm never going to help Derek again."

"You're serious," the other boy said, more as a statement than a question.

Stiles laughed. "Oh, yeah. I'm dead serious."

"But we need you," the blue eyed teen said.

"Why the fuck would I help you guys? You threw me away. You stole my best friend. After everything I had done for the pack. I saved Derek's ass all the damn time. So I don't care if a freaking vampire is in town. I don't care about your pack." His voice is loud and Stiles could see that it was scaring Isaac. "I was right. You're just a scared little puppy. I bet you thought the bite would give you power but you're still the same."

Isaac flinched. He'd never seen Stiles like this, no one had. "I'm s-sorry. Derek t-told me to get Scott away f-from you. I didn't w-want to," Isaac stuttered. Tears were very close to falling from his eyes and he was trying to fight it back. "I'm sorry."

"Well, you should be sorry," Stiles shouted. He turned to walk away.

"You always looked good to me," Isaac mumbled from the corner.

Stiles turned around and saw the other teen was curled against the wall, terrified and now crying. "What do you mean?" he snapped.

"You said that Danny never wanted you before. But I always liked you," Isaac admitted, even though he looked terrified that Stiles was going to strike out at him.

Stiles felt guilty. He wasn't mad at Isaac, not really. It was Derek's fault. Stiles knew that Isaac had only done what Derek told him to do because he was afraid of being hurt again. "If you'd asked, I would have said yes," Stiles said. He bent down, unable to fight the urge to give Isaac a chaste kiss on the lips. Isaac grabbed Stiles shirt and deepened the kiss. What he lacked in talent, he made up for with enthusiasm. Stiles returned the kiss, taking control of it.

Suddenly, Stiles broke away from Isaac and turned to leave. "Give it time, mutt. Maybe I'll change my mind about you."

-

Stiles and Allison decided to skip their last period in order to make their second move. They were driving to Deaton's office accompanied by Jeremy and Rebekah. They knew that Scott would be there after school, so they needed to move quickly.

"Who is this Deaton guy?" Jeremy asked from the back seat of Allison's car.

"He's the one who gave them the herb that traps humans," Allison answered. "It's his fault our fathers couldn't escape."

Stiles and Allison went straight to the back door of the office while the other two waited in the car.

"Stiles, Allison," Deaton said. He seemed surprised to see them. "What can I help you with?"

"We're helping the pack again and they sent us. We have a few questions. Can we come in?" Allison asked.

"Of course, come in," the vet said, stepping aside so that the two teens could come in.

"Letting us in was a big mistake, doc. I thought you were smart," Stiles said. He grinned when he saw the fear in the man's eyes.

Without warning Allison launched at the vet's neck, burying her fangs in it and drinking the blood until the man's body went limp in her arms.

"That was easy," Stiles said.

"Yeah," the girl agreed. Blood was still dripping from her mouth and she dropped Deaton's body like it was a toy that no longer amused her.

-

Several hours later the pack surrounded the vet's body. They were shocked. Deaton had always been so wise. If he could fall victim to the vampire, then was there any hope for them?

"This has to stop," Peter said. "This makes five bodies found drained of blood."

"I talked to him this morning," Scott said. "It doesn't make sense." His voice faltered and he leaned on Isaac. He was taking Deaton's death pretty hard, considering the man had been like a father to him. "He's smart, he would know better than to invite a vampire in."

"Quite contrary," a voice with a British accent said from behind them.

All turned around to find a man in his twenties smiling like a psycho.

"Who the hell are you?" Derek snapped.

"Easy, dog. Don't make me hit you with a newspaper," the man said.

"He's the vampire," Isaac whispered, smelling the blood coming from the man.

"You attacked my girlfriend," Jackson screamed. He launched himself at the vampire who easily kicked him to the other side of the room. In a flash, the vampire was holding Jackson by the neck, choking him.

"Very well, dogs. If you won't play nice, I'll snap this puppy's neck."

"Why are you here?" Derek asked.

"My name is Kol Mikaelson and I was quite bored so I killed some people to entertain myself," Kol responded. He noticed that Jackson was about to pass out and let go of his neck.

"You'll attract hunters," Peter warned.

"Oh, I know there are no hunters in the area anymore thanks to your pack. Consider this a warning. Leave me alone." With that, Kol easily snapped both of Jackson's arms. The werewolf screamed in agony. Kol moved much too quickly for them to catch and in an instant he was gone.

-

"We'll have to wait a while before we make our next move," Allison said. They were in a large tree outside the office, watching as the pack left, surrounding a wounded Jackson.

"I found my weakness," Stiles said abruptly.

"What do you mean?"

"Isaac," the honey eyed boy said with sadness in his voice. "He kissed me."

Allison gasped. "What did you do?"

Stiles shrugged. "I kissed him back. I kind of liked him before.

Allison nodded in understanding. "I get it. Scott followed me around all day and I felt so bad."

"Once this is over, maybe we can be happy again"

"I don't know. Even then, they'll grow old and we won't."

"At least we have each other," Stiles said, putting his arm around her in a playful hug.

"Great, I guess I'm stuck with you for eternity then," Allison joked.

"Yeah, aren't you lucky," Stiles quipped back.

Even though they were just joking around, they really were glad that they had each other. The thought of revenge was all consuming, but there were times that they let themselves think about life after revenge and it scared them a little.
