High School Demons

"CASSIE! STOP FIGHTING ME" Stiles hissed and finally I stopped, my entire body shaking like a leaf. Derek was dead. I lost another family member.

I needed to pull myself together. My panic wasn't helping anyone. I pulled out of Stiles's arms, taking in a breath as I tried to compose myself. "We need to barricade ourselves. Something to - something to put in the handles." I said, trying to keep my voice firm. My eyes scanned the floor and then out the window, my eyes falling on the garden shears as Stiles did. "Stiles, no no no!" I whisper yelled - but he was already opening the door before I could grab his jacket.

He carefully stepped outside and walked slowly towards them, both my eyes and his scanning for the Alpha. I saw it slide from under the Jeep and started pounding on the door, screaming for him to run. He scrambled towards us, and we dragged him inside and wedged them in the door behind him.

"We need to move, now come on come on." I said, dragging them away from the doors. We were all shaking, but I knew I needed to think, make a plan, somehow get us out alive. I wasn't letting them die, and I was not dying in this school.

Stiles made a sharp left and dragged us into a classroom, one with a lot of windows I might add.

Scott went to move a desk and it squealed, and Stiles and I both shushed him. "The doors not gonna keep it out, and neither will the desk." Stile muttered.

"I know," Scott said. I was silent, eyes scanning the windows as my brain racked possible outcomes, the boys whisper arguing in the background.

"It's your boss."

"What?"

"Deaton? The Alpha? Your boss."

"No."

"Yes, murdering psycho werewolf."

"That can't be."

"Oh, come on. He disappears and that thing shows up 10 seconds later to toss Derek up 20 feet in the air?" I sucked in a breath, and I felt Stiles' eyes shift towards me momentarily before focusing back on scott. " That's not convenient timing?"

"It's not him." Scott hissed back.

"He killed Derek."

"No, Derek's not dead. He can't be dead."

"Blood spurted out of his mouth okay? That doesn't exactly qualify as a minor injury. He's dead, and we're next."

"Stiles shut up," I muttered, looking over at him with a clenched jaw. "You aren't being helpful. We need to get to Stiles' jeep, get Derek, and get out of here."

We all scrambled over to the window, looking at the Jeep through the glass. My brow furrowed slightly. Scott went to open the window, but Stiles reached out to stop him.

"The school's climate controlled, they won't open," he explained.

"Then we'll break them." Scott countered.

"Which will make a lot of noise," I argued, shaking my head.

"Then we run really fast... like really fast." Scott said, his eyes scanning the parking lot, just like mine were. "Stiles, what's wrong with the hood of your jeep?" He asked.

"What do you mean what's wrong? Nothings wrong with my Jeep."

"The hood Stiles, it's bent." I mumbled, my stomach twisting with nerves as I looked at the damage.

"Like dented?"

"No, I mean bent."

"What the hell-" Stiles' string of curses was cut off by the window shattering and something skidding across the floor. I dropped down under the wall, dragging Stiles and Scott down with me. It was Stiles' battery.

Stiles and I both went to stand but Scott pulled us back down. "Don't move."

"We have to move!" I hissed, glaring at him

"He could be right outside." Scott hissed back.

"He is right outside." Stiles muttered.

"Just let me take a look!" Scott said, going to peak above the window sill and out the window before shaking his head and dropping back down. "Nothing."

"Move now?" I asked, and both boys nodded in unison.

"Move now."

We quickly made our way into the hallway and Scott tried to take the lead.

"No no no, somewhere without windows," Stiles said, pulling Scott and I in the other direction.

"Every single room in this building has windows." Scott argued.

"Then somewhere with less windows." I murmured.

"The locker room." Scott said, his breathing heavy as we took off running again. As we walked in, Scott turned to look at Stiles. "Call your dad."

"And tell him what?"

"I don't know, anything. There's a gas leak, a fire, whatever. If that thing sees the parking lot filled with cop cars, it'll take off."

"Okay and what if it doesn't? What if it goes completely terminator and kills every cop in sight, including my dad?"

"They have guns...?"

"Yea, and Derek had to be shot with a wolfsbane laced bullet to even slow him down, you remember that?"

I could hear noises steadily getting louder and closer and I felt my heartbeat speed up, cursing myself knowing it could hear us.

"Then we have to run for it."

"Scott, there's nothing near the school for at least a mile, and we can't outrun that thing." I said, my eyes still trained on the door.

"What about Derek's car?"

I flinched, but neither boy saw. "That could work," Stile said, and I could already see the wheels turning in his head. "We go outside, we get the keys off his body, and then we take his car."

"And him, we are not leaving his body out here." I hissed, glaring sharply at Stiles.

"Fine, okay Cassie, and him" Stiles said, turning to walk towards the door. I grabbed him by the shirt, about to tell them no when the noises got louder again. We all froze, my chest tightening. The shadow outside the door got a bit darker and I scrambled backward, dragging Stiles back with me.

We scrambled into a locker, his back against the inside and my face pressed against his chest. I held my breath, trying to slow my pounding heart, eyes tightly closed. I could feel Stiles' hand tighten on my bag as the door creaked open, his chest rising as he sucked in a breath. I tried not to move, saying a silent prayer.

Suddenly, Scott's locker door was pulled open and I heard a yell, causing me and Stiles to tumble out of ours. Stiles shushed the man, as my eyes flickered around the room in panic.

"Don't shush me! What are you kids doing here!" The janitor asked, his voice rising.

"Please, please lower your voice, I begged, my own barely above a whisper.

"All three of you, get out!"

"Just listen, for half a second okay?" Stiles said, stepping forward and pushing me back behind him.

"Not okay! Get the hell out of here right now." He said, shoving us to the door.

"Just give us one second to explain!" Stiles asked, turning to look at the man.

"I said get the hell out-" He was cut off by a guttural growl and was dragged back into the room, his hands slamming against the windows with blood.

A strangled sob escaped my lips as I stumbled back and away, his screams filling the air.

"Run, run now!" I said, dragging both boys away from the gruesome scene. Scott tried to fight me but I pulled him away, shaking my head. "No hero complex now, please, just running!" I yelled, pulling them both by their arms.

We got to the door to the outside and Stiles tried to push it open, only for it to rattle.

I swore under my breath, shaking my head. "It pushed something against it."

"A dumpster." Scott said, peeking his head through the crack.

Stiles went to slam his body into the door. "Come on, help me!" He said, but Scott just dragged him back.

"It won't do any good."He said, and we turned back to head into the school.

"I'm not dying here. I'm not dying at school," Stiles muttered, and I sighed.

"Nobody is dying, period, okay. We're going to get out of this." I soothed, giving him a look.

"Okay well what is he doing? What does he want?" Stiles asked, throwing his hands up in the air.

"Me! Well, Cassie and me, I think. Derek said it's stronger with a pack." Scott said.

"Yeah, great. A psychotic werewolf who's into teamwork. That's beautiful." Stiles huffed.

Scott and I had both frozen, our eyes locked on the Alpha's form on top of the school. It growled and took off running, and we immediately did the same. It smashed through the window, just a few feet behind us.

It felt a bit like that first night in the woods; my hard racing, my shoulder burning, my chest tightening to the point where it hurt to breathe. All I could hear was the growl of the Alpha and the sound of our feet pounding on the tiles. We stumbled down the stairs, my mind trying to think of where we could go, where we could be safe. Nothing came to mind, every place felt vulnerable.

My hand was laced tightly with Stiles, and finally it felt like we had gained some ground, but I wasn't sure how. We slammed into a set of lockers, trying to catch our breath. I couldn't hear the alpha, but it didn't make me feel any better. Scott peeked around the edge as the growl echoed, taking a shaky breath before whispering go to Stiles and I.

We took off running again, pushing through another door before Stiles turned to face us.

"We have to do something."

"Like what?" I countered, giving him a look.

"I don't know! Hurt it? Kill it? Inflict mental anguish on it or something!"

The low rumble of a growl echoed again. I glanced at Scott, seeing the panic I felt reflected on his face. Stiles fumbled for his keys, the jangling making my eyes shoot to him as I shushed him. He waved me off before grabbing them and tossing them the opposite direction, causing the alpha to run towards the noise. We sped out of the room, slamming the door behind us.

"The desk!" Scott pointed, and the two boys worked to push it in front of the door.

"Alright" I breathed a soft sigh of relief pursing my lips as I glanced through the glass of the door. "We should keep moving, I doubt that will keep it very long."

Scott jumped across the desk, but Stiles leaned towards the glass again.

"I just wanna get a look at it! It's trapped, okay? It's not gonna get out." I shook my head at Stiles, trying to get him to reconsider, but he was already back on top of the desk. "Yeah, we got you."

"Will you shut up!" Scott whispered.

"Why? I'm not scared of this thing!" Stiles countered, just as the alpha slammed against the door, causing Stiles to tumble off. Another crash echoed and the ceiling began to creak.

"Now we run again," I mumbled, and the three of us took off down the hallway. My breath was coming in ragged gasps, my chest aching with the strain. After a few minutes, we slowed to a stop, both Scott and I freezing.

"Do you hear that?" he asked, and I nodded.

"Hear what?" Stiles asked, looking between us.

"It sounds like a phone ringing," I said, looking around.

"And I know that ring. It's Allison's phone." Scott said, panic on his face. I swore under my breath.

"Stiles, your phone, call her. Now" I said, and the boy fumbled for his phone, pressing her contact before handing it off to Scott.

"Stiles?" I heard Allisons voice through the phone.

"No, it's me. Where are you?" Scott asked.

"I'm in the school looking for you, why weren't you at my place?"

"Where are you right now?" Scott pressed, already moving. Stiles and I hurried after him.

"I'm on the first floor."

"Where, where are you exactly?"

"The swimming pool."

"Get to the lobby, now."

"Okay, okay I'm coming." Allison said, before hanging up. The three of us took off in a sprint, skidding down the stairs and through the door. Allison was standing there, arms wrapped around herself.

"Why did you come? What are you doing here?" Scott asked, looking over her as if checking for injuries.

"Because you asked me too?" Allison replied, confusion evident on her face.

"I asked you too?" Allison showed the three of us the phone, and Stiles and I glanced at each other.

"Why do I get the feeling you didn't send this message?" she naked

"Because he didn't." I murmured. "Did you drive here?" I asked.

"Jackson did."

I held back the urge to swear again. "Jackson's here?"

"And Lydia too. What's going on? Who sent this text?" Allison's voice was rising, the panic clear. Just as she did, Jackson and Lydia came through another door.

"Finally, can we go now?" Lydia said, barely acknowledging us. A heavy thud echoed, and the cold fear crept through my chest.

"Run!" Scott yelled, grabbing Allison's hand as we all took off. The low growls of the alpha came from behind us, causing us to speed up as we careened around corners. Finally, we crashed into a classroom, bolting the door shut. "Help me with this!" he said, gesturing towards the chairs.

Jackson moved to help him while Stiles protested, looking between the massive wall of windows and the door.

"Scott what was that?" Allison asked

"What fell through the ceiling?" Lydia added, looking terrified.

"Guys, can we wait a second?" Stiles voiced. I stayed quiet, too overwhelmed to think. He repeated the words again, as everyone else scrambled to push things in front of the door. Nobody seemed to listen, and I shot him an apologetic look. "HELLO!" he yelled, causing the other four to turn towards him. "Okay nice work. Really beautiful job everyone. Now, what should we do about the 20 foot wall of windows?" The room was silent before Allison spoke.

"Can somebody please tell me what's going on? I'm freaking out here and would like to know why. Scott?"

Scott walked away, rubbing his face and avoiding eye contact.

Stiles stepped forward. "Somebody killed the janitor. The janitors dead."

"What is he talking about? Is this a joke?" Allison asked, looking again at Scott for confirmation.

"What - who killed him?" asked Jackson, now turning to me.

"No, no, no, no this was supposed to be over. The mountain lion was killed." Lydia stammered, and I moved to wrap my arm around her.

"Don't you get it, it was never a mountain lion," Jackson snapped, and I gave him a glare

"Who was it? What does he want? What's happening? SCOTT" Allison's voice was close to a beg, and yet Scott stayed silent.

"I-I-I don't know. I just know if we go out there he's gonna kill us," he said finally, turning to face us.

"Us? He's gonna kill us?" Lydia said, looking up at me.

"Who?" Allsion pressed again, "Who is it?" She looked between the three of us, and I looked at Stiles.

"It's Derek. It's Derek Hale," Scott said finally, causing my jaw to drop open.

"Derek killed the janitor?" Jackson asked.

"You're sure?" Allison seemed incredulous, looking at me. I simply just stared, shocked at Scott.

"I saw it. Derek killed them."

"All of them?" Allsion asked.

"Yes. Starting with his own sister." At those words from Scott I pushed away from Lydia, walking towards the windows, fighting back tears. "It's been Derek the whole time. He's here with us. And if we don't get out now he's going to kill us too."

I felt the hot anger in my chest, glaring at Scott as I turned back to him. He caught my eye before quickly turning away.

"Call the cops," Jackson said, looking at Stiles.

"No."

"What do you mean no?"

"I mean no. Do you wanna hear it in Spanish? Nó." Stiles retorted. "Look Derek killed three people we don't know what he's armed with."

"Well your dad is armed with the entire sheriff's department. Call him!"

"I'm calling." Lydia said, pulling out her phone.

"No Lydia, would you just hold on a sec," Stiles said, walking towards her just to get shoved back by Jackson.

"Yes, we at Beacon Hills High School were trapped. We need you to...but..." she trailed off. "She hung up on me."

"The police hung up on you?" Allison asked.

"She said they got a tip that there were gonna be prank calls about a break in at the high school. She said if I called again they were gonna trace it and have me arrested."

"They trace your cell. They'll send a squad car to your house before they come here." I said tiredly, meeting Stiles' eyes.

"What is this? Why does Derek want to kill us? Why is he killing anyone?" Allison said.

The room went silent, turning towards Scott.

"Why is everyone looking at me?"

"Is he the one who sent the text?" Allison asked.

"No! I don't know!"

"Is he the one that called the police?"

"I DON"T KNOW" Scotts voice echoed, and Stiles stepped forward to push him back.

"Let's ease off the throttle here, yeah?" Stiles said as I stepped to follow them. "Okay first off, throwing Derek under the bus, nicely done."

I gave the boy a sharp glare, and Scott stuttered, "I didn't know what else to say. I had to say something. And if he's dead, it doesn't matter."

"Except he's not." I shot, and both boys looked at me with pity.

"Oh god I totally bit her head off."

"And she'll get over it," Stiles interrupted. "But we have bigger issues at hand, like how do we get out alive?"

"But we are alive... it could, and should, have killed us already," I said quietly, realization dawning on me.

"It's like it's cornering us," Scott finished.

"So what, he wants to eat us all at the same time?" Stiles said, the sarcasm evident in his voice.

"No. Derek said he wants revenge."

"Against who?"

"Allison's family. Maybe that's why she was sent that text," I murmured, glancing back at the other three.

"Okay asshead, new plan. Stiles calls his useless dad and tells him to send someone with a gun and decent aim, are we good with that?" Jackson interrupts.

"He's right. Tell him the truth if you have too. But call him." Scott said.

"I'm not watching my dad get eaten alive," Stiles said quietly, and I couldn't help but agree.

Jackson lunged forward, grabbing Stiles by the shoulder. "Alright, give me the phone." Stiles turned and punched him, sending the other boy stumbling as Allison ran to his side.

"Shit, are you okay?" I asked, grabbing Stiles' hand. The room was tensely silent before Stiles finally pulled up his phone and called his Dad, but the sound of crashing at the door made us all freeze.

"The kitchen door, it leads to the stairs." Stiles said, backing away from the door, my hand still in his.

"But that only goes up," Scott said.

"Up is a hell of a lot better than here." I countered, and we took off through the door, just as the blocked door opened. We raced up the stairs, turning into the chemistry classroom, one of the few unlocked doors.

We all froze, breathing heavily before a low growl sounded from the hallway. We all froze before it passed.

"Jackson, how many people can fit in your car?" Stiles asked.

"Five. if someone sits on someone's lap."

"Five? I barely fit in the back seat." Allison said.

"It doesn't matter. We can't make it there without drawing attention to us." I said, shaking my head.

"What about the door that leads to the roof and we can go down the fire escape and be in the parking lot in like five seconds?" Scott said.

"That's a deadbolt."

"The janitor has a key." I whispered, and Stiles and Scott saw the plan forming in my head.

"His body has it," Stiles hissed.

"I can get it. The scent of the blood is strong enough for me."

Scott shook his head. "I should go."

"Well gee, that sounds like an incredibly bad idea for both of you."

"There's not another plan. I'm getting the key." I said, pushing past them towards the door. Scott followed, but Allison stepped in front of us.

"Are you serious?"

"It's the best plan. Someone has to get the key if we want to get out of here." Scott said, trying to soothe her.

"You can't go out there unarmed."

Scott grabbed a ruler and gave us a forced smile.

"There's gotta be something else." Stiles said.

"There is..." Lydia looked around the classroom. "We have everything we'd need to make a self igniting molotov cocktail."

I grinned at my smart best friend. "Well we don't have a key for that either." Stiles said with a huff.

Jackson sighed, before using his elbow to smash through the glass of the cabinet. We got to work, Lydia giving instructions as I helped as best as I could. After a few minutes it was done, and she handed it to me. I was thankful she knew better than to tell me not to go, though the fear in her eyes was hard to miss.

"No. No this is insane you can't do this," Allison said, looking at Scott. I sighed, moving towards the door.

"We can't just sit here waiting for Stiles's dad to check his messages," Scott countered.

"You could die, you know that right? He's killed three people."

"And we're next. Somebody has to do something," I said, my voice final. "Scott, we gotta go."

Allison moved to stop him again, whispering something to him as tears streamed down her face. I stopped, sighing with my hand on the door knob.

"Lock it behind us." Scott said, pulling away as Allison kissed him. We stepped out the door, moving through the hallway. I let Scott take the lead, the cocktail gripped tightly in my hand. The halls were silent, eerily so, and I tried to call my pounding heart. We made our way towards the gym, no sign of the alpha yet. The bleachers were open, but Scott tilted his head as if to say it was under there. I tried not to swear but nodded, moving under with him. I saw the body, and pointed, Scott taking the lead. The blood dripped from the janitor, and splattered on my shoes as we stood under him. Scott climbed up to grab the keys.

With a low creak, the bleachers began to shut. I looked at him, he was still fumbling but we were going to get crushed. I took off running, both of us barely making it out to the gym before they slammed shut. The alpha stood across the basketball court and I chucked the molotov cocktail at it. The glass shattered, but nothing happened. I froze, cursing whatever god was listening before grabbing Scott.

We weren't quite fast enough, the Alpha tackling us and letting out a deafening growl. Scott let out a scream and was writhing on the ground, while my head felt like it was going to split open. Scott shifted around, before turning back towards me, his face morphed. He looked blankly at me, and I took off running. That was not Scott.

I headed towards the west wing, hoping to lead Scott away from the others. I heard the pounding of footsteps behind me, but they sounded too heavy. I didn't slow down, but my heart sank as I realized who was behind me. I took a corner too sharp, losing my footing as I slammed into the ground, sprawled out on the linoleum.

Flipping on my back, I was faced with the maw of the alpha.

"You silly little girl," it hissed. I scrambled to get up, but its claws sank into my shoulders, pinning me in place. The pain burned, and I let out a scream that I didn't even know I could make. "You need to learn to listen and follow directions from your elders. You will fall in line." there was a sickening squelch as the claws slid out from my shoulders, and the pain was so severe it tinged my sight with black.

"A shame you're just like your mother," was the last thing I heard before everything went dark.

-----☾-----

I woke up in the back of an ambulance, not moving. They were wrapping my shoulders, and the EMT looked at me pitifully. "It's okay. You're alright. Not sure what Derek did to you but no stitches is a good thing." The sound of Derek's name sent a fresh wave of pain over me.

"What about my friends?" I asked, and the EMT tilted her head. I saw Scott and Stiles and let out a breath, thanking god.

"You're good to go sweetie, the Sheriff wants to talk to you though."

I nodded blankly, sliding out to walk towards the boys. Stiles saw me first, moving toward me quickly. I let him wrap me in a hug, breathing deeply as I buried my face in his shirt.

"You need to stop getting hurt by the alpha," he said, but the scold was damped by the relief in his voice. I laughed, looking up at Scott.

"I know. But something isn't right. It should have killed us." I said, shaking my head.

"It wants to get us in its pack. But we have to get rid of our old pack first." Scott said.

"What old pack?" Stiles asked.

"Allison. Lydia and Jackson. You." I said, my voice tired. Stiles stayed silent.

"The alpha doesn't want to kill us," he said finally.

"He wants me to do it..." Scott finished. "And that's not even the worst part."

"How in the holy hell is that not even the worst part?"

"Because when he made me shift, I wanted to do it. I wanted to kill you. All of you."

I exhaled slowly, shaking my head. "But you didn't."

He moved away, his eyes widening as he saw Allison. I saw the Sheriff and moved towards him instead. He gave me a sad look, wrapping me in a hug.

"You okay kiddo?" I nodded as I pulled back. "Good. Those cuts looked nasty. But, you know I gotta call Blaise now."

I exhaled softly, nodding my head. I knew it was coming.

"But, I gotta ask, did you see Derek? Was he the one who hurt you?" I froze, looking down at my feet. Derek could be dead. But if he wasn't... I couldn't do that to him. I loved Scott, but couldn't back up this lie.

"No. I didn't see Derek. I don't think he did this. He - he would never hurt me."

The sheriff sighed but nodded. "Go wait in the car okay? You're gonna come home with us, and I'll call your brother tonight." I nodded, walking towards his car and sliding in the back seat. Stiles slid in beside me, and I leaned my head on his shoulder.

"That was dumb you know. Going out with Scott." He said quietly.

"I know. But when have I ever let one of my friends do something dumb alone."

He laughed, shaking his head. I could feel it from my position.

He paused, letting out a slow breath. "You scared me. When you weren't with Scott. When the EMTS brought you out covered in blood. Shit Cassie, I thought I lost you."

I stayed quiet, not sure what to say.

"I'm sorry. But you can't get rid of me that easily."

He laughed, and for a moment the world felt a little less scary.

"Get some sleep. I'll make sure you get into bed." I nodded, letting my eyes close as I relaxed into him. It didn't take long to fall asleep, and for the first time in a long time, I slept through the night.
