A/N: Okay one thing before you get to the story. I have been informed that the brotp of Scott and Percy is now gonna be referred to as McWin. (I'll still respond to any other names but that's the name people have decided on for them). I'm sooooo sorry this chapter is so long. I just couldn't stop it anywhere in the middle, and it just kept going and going. But it's done and it's here for you guys to enjoy. Sorry it gets kind of slow in the middle, I was running out of ideas. Well as always I don't own Teen Wolf, just Percy. I hope you all like it! R&R!

A howl rips through the air and the boys send a look at each other before each of them grabbed one of my arms and drags me into a nearby classroom.

"The desk." Stiles says letting go of my arm and rushing for the teacher's desk. Scott hurries to the other side and pushes the desk towards the door while I look around nervously. "Shh. Stop, stop!" Stiles whispers holding his hand up to Scott. "The door's not gonna keep it out."

"I know." Scott breathes out and I shuffle closer to the two of them.

"It's your boss." Stiles states out of breath.

"What?" Scott asks glaring at his friend.

"Deaton, the Alpha?" Stiles tries to clarify looking over his shoulder to check on me. "Your boss."

"No." Scott shakes his head furiously.

"Yes, murdering psycho werewolf." I reach out and motion for Stiles to shut up.

"That can't be." Scott responds confused.

"Oh, come on. He disappear, and that thing shows up 10 seconds later to toss Derek 20 feet through the air?" Stiles leans across the desk whispering ferociously. "That's not convenient timing?"

"It's not him." Scott hoarsely responds.

"He killed Derek." Stiles continues.

"No, Derek's not dead. He can't be dead." Scott looks to me for affirmation but I'm heading to the windows and don't see it.

"Blood spurted out of his mouth, okay? That doesn't exactly qualify as a minor injury." Stiles slams his hands on the desk in between them. "He's dead, and we're next. Percy…. You agree with me?"

I turn to the two of them and shake my head. "I don't really care who the Alpha is…. He is gonna try and kill us even if we know who it is. I, for one, do not want to die in high school." I gesture around the room before stopping and pointing a finger at Stiles pointedly. "Derek is not dead until we have proof of that…." Stiles opens his mouth to say something but I shush him before continuing. "Now can we find a way to get out of here alive?"

"What do we do?" Scott asks looking over at me.

"Why are you asking me?" I hold my hands up in an annoyed shrug. "I'm not the plan maker here." I gesture at Stiles.

"We get to my Jeep, we get out of here, you seriously think about quitting your job, good?" Stiles looks at me with a smirk and I roll my eyes turning to Scott waiting for his answer. Scott nods in response and they both tiptoe over to the windows I'm standing in front of. Scott attempts to open the one closest to us and Stiles and I both stop his hand. "No, they don't open. The school's climate-controlled." Stiles says calmly pulling Scott's hand away from the window.

"Then we break it." He says turning in the spot looking for something to break the window with.

"Which will make a lot of noise." Stiles voice croaks in fear.

"Then…." Scott looks back out the window surveying the surrounding area. "Then we run really fast." I scoff and look down at my feet.

"Note to self….. start wearing better shoes." I mutter under my breath looking at my lightly heeled shoes.

Scott's gaze floats in the direction of the Jeep before turning back to Stiles. "Really fast." He restates turning and leaning past my shoulder to look closer at the Jeep. "Stiles, what's wrong with the hood of your Jeep?"

"What do you mean? Nothing's wrong." Stiles answers looking at the his friend.

"It's bent." Scott answers with a nod out the window, causing me to turn and look.

"Like, dented?" Stiles moves forward frantically.

"No, I mean bent." Scott replies.

"What the hell….." Stiles was cut off as an object comes flying through the window sending glass flying everywhere. We all duck down and cover our heads as the sound of metal sliding across the floor filled the room. Stiles shines the light across the room to see what it was before pointing shakily at it. "That's my battery."

I place my hand on the ground to steady my crouch and end up with glass shards embedded into my palm. I pull back with a hiss before looking at Scott. "That right there is why we didn't bring my car." Stiles goes to stand up and Scott pulls him back down.

"Don't move." Scott whispers at Stiles.

"We have to move." Stiles answers flattening himself against the wall.

"He could be right outside." Scott huffs out as I slide over to the wall and peek out the window.

"He is right outside." Stiles reaches over Scott and grabs the back of my jacket pulling me down from the window.

"Just let me take a look." Scott says as I swat lightly at Stiles hand. He inches upward and looks around the school yard.

"Anything?" Stiles whispers slowly joins his friend looking out the window.

"No." Scott shakes his head.

"Move now?" Stiles grabs my wrist waiting for Scott to answer.

"Move now." The short reply came a few seconds later and Stiles leads me out into the hallway continuously peeking over his shoulder. Once in the hallway Scott taps Stiles' chest and points off to our right. "This way."

"No, no, no, no." Stiles releases my wrist and stops Scott.

"What?" Scott hisses out looking around worriedly.

"Somewhere without windows."

"Every single room in this building has windows." Scott growls impatiently as Stiles shines the flashlight past me.

"Or somewhere with less windows." Stiles clarifies his statement.

"Locker room." I pipe up bringing the boys heads up.

"That'll work." Stiles nods and we all rush down the hallway in the direction of the locker rooms. When we get to the boy's locker room I push through the door and sigh.

"Just once…. Can we have a werewolf crisis in the girl's locker room?" I grumble as the smell of gym socks reaches me. "At least it would smell better."

"Call your dad." Scott whispers to Stiles placing his hand on my arm and squeezing past me.

"And tell him what?" Stiles asks staying close to my side as we head around a couple lockers.

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

"What if it doesn't?" Stiles spits out angrily. "What if it goes completely Terminator and kills every cop in sight, including my dad?" I look worriedly over at Stiles but don't say anything.

"They have guns." Scott squeaks out.

"Yeah, and Derek had to be shot with a wolfsbane-laced bullet to even slow him down, you remember that?" Stiles argues back and I place a hand on his shoulder turning in the direction of the door.

"Then we…. We have to…. We have to find a way out and just run for it." Scott sighs out looking sadly at his friend.

"Again with this whole running idea." I groan out.

"There's nothing near the school for at least a mile." Stiles answers solemnly.

"What about Derek's car?" Scott asks the light bulb over his head springing to life.

"That could work." Stiles answers hopefully. "We go outside, we get the keys off his body" He shudders at the thought before continuing, "and then we take his car."

"And him." Scott states simply.

"Fine. Whatever." Stiles answers looking dejected.

"And the alpha is just going to let us do this? Or does your plan include someone playing distraction?" I hiss out bringing both their eyes to me in a glare. "Or we can just ignore logic and go." I head towards the door and the boys start to follow me. Stiles reaches around me to open the door and Scott grabs his arm just before he comes in contact with the handle.

"What?" Stiles whispers looking down at his friends hand.

"I think I heard something." Scott answers tilting his head towards the door.

"Like what?" Stiles jerks his hand away from the door with a squeak.

"Shh, quiet." Scott shushes his friend. After a second or two both the boys start backing up staring at the door. Stiles puts his hand behind him and pushes me back so they don't stumble over me. The flashlight beam heads towards the door and I reach forward covering the lens before pushing the button on top turning of the light. "Hide." Scott whispers to both of us looking around the room.

Stiles grabs my arm and shoves me into a nearby locker before climbing in behind me. I yelp at the sudden movement.

"No, no, Stiles." Scott hisses at the clanking noises made by the sudden attack on the locker door before turning and stepping into a locker himself.

"You couldn't get in your own locker?" I growl out under my breath as his hand collides with my jaw. He shushes me and shifts slightly trying to give us a little more room but just ends up pushing different parts of his body closer to mine. "Stop moving." I reach up and hold his shoulder firmly as my heart beat starts rising and I know Scott can probably hear it by now. Stiles tries to shift one of his legs and ends up stepping on one of my feet and I groan in pain. "Stiles…." I tap his shoulder whispering the pain evident in my voice, "Get off my foot." Stiles moves awkwardly trying to put some space between us but ends up digging the flashlight into my side. I squirm a little and Stiles stiffens and I stop and look up at him. "What?" I hiss seeing his eyes widen and he shakes his head in response. We both jerk our heads up when we hear the door to the locker room creak open and my forehead collides with his chin making me mutter curses silently as stars appear in my vision. I let my head rest on his shoulder waiting for the stars to dissipate and Stiles shushes me again placing a hand on the back of my head and pushing me into his shoulder to keep me quiet.

We both hear footsteps outside and I silently curse my heartbeat for being so loud. Percy, you need to chill. Now! Stiles jumps slightly as we hear screaming right outside and we both tumble out of the locker.

"Ah! Son of a bitch!" I look up and see the janitor panting in fear as his gaze falls over all of us.

"Shh, quiet!" Stiles whispers harshly one hand out to the janitor and the other down to me helping pull me off the floor where I was sprawled.

"Quiet my ass, what the hell are you trying to do, kill me?" The janitor yells out as I lean against the locker I had just fallen out of rubbing my side. "All of you out."

"Just listen for half a second, okay?" Stiles responds taking his eyes of me and wheeling around on the janitor.

"Not okay. Get the hell out of here right now." The janitor starts pushing Scott towards the door and gestures for me and Stiles to follow. With a light groan I push off the locker and shuffle behind Scott until the janitor gives all of us a light shove out the door.

"God, just one second to explain." Stiles pleads with the guy catching me from the light stumble I had from being pushed.

"Just shut up and go." I straighten up as the janitor points down the hallway. I look up at him just in time for a growl to reach my ears and the janitor to be yanked backwards before the door slams shut. I raise a hand to cover my mouth as his screams permeate the air and he is slammed into the door repeatedly. Scott pushes forward and tries to open the door as Stiles pulls me back and tries to get me to turn away.

"No, no." Stiles gives up and grabs Scott pushing him down the hallway before yanking on my arm pulling me behind him. I race after him the screams still pulsing in my head leaving me in a light daze. We reach the end of the hallway and both Scott and Stiles slam into the door to open it just to bounce back when it doesn't budge. Stiles glares down at the handle before slamming into it a few more times.

Scott reaches forward and grabs his friend pulling him off the door. "Stiles, stop!" Scott lightly puts his hand on my back leading me off down a side hallway as Stiles mutters beside us.

"I'm not dying here. I'm not dying at school." Stiles finally says aloud for the both of us and Scott turns to him.

"We're not going to die." He growls out shooting his friend a look.

"God, what is he doing? What does he want?" Stiles panics looking around and I grab his hand trying to offer a little bit of comfort.

"Me." Scott growls out loudly. "Derek says it's stronger with a pack."

"Yeah, great." Stiles looks down briefly at our hands before turning to his friend with a sarcastic look. "A psychotic werewolf who's into teamwork. That's… That's beautiful."

Scott looks out the window to my left and stops both of us bringing our heads reeling around to look. On top of the building across the way was the same crouching figure I had seen in the video store, reaching up I grab at Scott's jacket and push him back down the hallway where we had just come from before racing after him pulling Stiles behind me. The window behind us shatters and I reach up instinctively to cover my head, while trying to run faster. The snarling behind us only encouraged us to run faster and I follow Scott as he bursts through a door into the stairway heading down.

We continue running until we get to a side hallway lined with lockers, where Stiles pulls me around the corner and forces me to crouch down. Scott peeks out around the corner as light growling echoes through the hallway and I stand up and grasp his sleeve lightly ready to pull him back. He cringes back and leans against the lockers panting and squeezing his eyes shut.

'What?' Stiles jerks lightly on his sleeve mouthing.

'Go.' Scott silently responding jerking his chin towards the hallway expanding behind us. I look at him worriedly before stepping back with a nod and jogging quietly down the hallway. The boys follow behind me quickly as I try to figure out where to go. A snarl from behind us brings all of us wheeling around fearfully.

"All right, we have to do something." Stiles says breaking the silence.

"Like what?" Scott asks looking over his shoulder at his friend.

"I don't know. Kill it, hurt it, inflict mental anguish on it…. Something." Stiles gestures wildly.

I pat down my jeans lightly before shooting Stiles a glaring look. "I seem to have left my 'Guide to Mental Anguish' in my other pants." Glass shatters and distant growling can be heard making us all jump. Stiles looks into the room next to us and then down the hallway before pulling out his keys.

"Wait a minute, no…." Scott whispers before being shushed by Stiles. He tosses his keys into the room and turns wrapping an arm around both me and Scott pushing us back. I watch with my mouth agape as the Alpha comes charging down the hall and into the room. Stiles scrambles to the door and slams it shut leaning against it.

"The desk. Come on, the desk." He urges us pointing the flashlight beam at the desk standing against the wall beside the door. I tap Scott at the door and point for him to help me and we spin the desk until it is lengthwise across the hallway holding the door closed. The desk lets out a metallic screech as the Alpha slams against the door trying to get out and Scott pushes me behind him protectively.

"He can't…." Scott starts to say as the desk holds up against the abuse before chuckling lightly. I peek around his shoulder and see Stiles smiling at the fact that his idea worked. A bang on the door makes Stiles jump and cringe away before turning to the two of us huddled on the other side of the desk.

"Come on, get across." Stiles nods at both of us gesturing for us to climb over the desk. "Come on!"

I look wearily at the door before mouthing 'What?'. Scott helps me clamber up and over the desk and Stiles wraps an arm around my waist pulling me back away so that Scott can hurry over. Stiles lets go of me and starts to head over to the door.

"What are you doing?" Scott smacks his arm causing Stiles to start.

"I just wanna get a look at it." Stiles whispers waving the flashlight at the door.

"Are you insane?!" I reach forward to grab at his arm to pull him back.

"Look, it's trapped, okay?" He tries rationalizing with me with a shrug. "It's not gonna get out." He gives me a reassuring smile before climbing onto the desk. Scott places an arm in front of my to push me back if needed. Stiles shines the light through the tiny window and leans closer. "Yeah, that's right, we got you….."

"Will you shut up?" Scott hisses.

"I'm not scared of this thing." Stiles stares his friend down as a loud growl and a bang send him tumbling off the desk to our feet. "I'm not scared of you. Right, 'cause you're in there, and we're out here." I push past Scott and reach up to silence Stiles, "You're not going any….." We all turn as a crash comes from in the room.

"You had to open your mouth and jinx us didn't you?" I growl pushing both the boys back as the ceiling tiles start creaking and sprinkling dust down on us. "I hate you…. I hate you so much." I groan out before shoving the boys off down the hallway when a ceiling tile falls to the floor. I race after them constantly looking over my shoulder but seeing nothing.

Scott stops us as we walk down a hallway quickly. "Wait. Do you hear that?" I just look over at him with a look that screams 'Really?'.

"Hear what?" Stiles spins around shining the flashlight in every direction.

"It sounds like a phone ringing." Scott answers with confusion hanging in his voice. "I know that ring. It's Allison's phone."

"What do you mean Allison's phone?" I hiss out as Scott holds his hand out to me.

"Give me your phone." He urges me faster not answering my question. I pull my phone out of my jacket pocket and hand it over, where he instantly dials a number.

"No, it's me, where are you?" Scott responds to Allison's greeting. "Where are you right now? Where? Where are you exactly?" I inch closer and try to hear what Allison is saying but Scott leans away. "Get to the lobby. Go now." Scott hangs up and hands me the phone before racing off in the direction of the lobby.

"Scott?" I pocket my phone quickly and tear off after him with Stiles on my heels. We burst through the doors of the lobby and see Allison coming from the opposite direction.

"Why did you come? What are you doing here?" Scott asks as soon as he sees her.

"Because you asked me to." She looks at him with her eyebrows raised.

"I asked you to?" Scott looks at me confused and I shrug. Allison holds her phone up and shows us a text saying 'Meet me at the school. URGENT –Scott'.

"Why do I get the feeling you didn't send this message?" Allison asks looking down at her phone and then up at Scott.

"Because I didn't. Did you drive here?" Scott asks glancing around the room.

"Jackson did." Allison answers shaking her head. I throw my hands up and mutter under my breath.

"Jackson's here, too?" Scott groans out mirroring my frustration.

"And Lydia, what's going on?" Allison demands as her phone goes off in her hand. "Who sent this text?" Allison answers her phone, "Where are you?" She asks just as the door behind her opens to reveal Jackson and Lydia.

"Oh good… Now it's a party." I mutter turning to Scott. "Can we leave now?"

Lydia comes to a stop beside Allison and sighs, "Finally. Can we go now?" Allison nods in response as a thud sounds from the ceiling. I reach behind me and grip Stiles' sleeve while looking at the ceiling. Everyone else looks up too and Scott gives us the best piece of advice ever.

"Run!" He shouts pulling Allison behind him, I usher Lydia and Jackson after them before following right behind. We just hit the stairs when the ceiling collapses with a growl. We all stumble down the hallway trying to look over our shoulders to see what is pursuing us. We burst through the doors at the end of the hall and Stiles turns to make sure everyone is in as I take in our surrondings. Scott works on locking the doors, "Help me get this in front of the door." He pushes Jackson over to the milk machine sitting alongside the door.

I groan as I see the windows taking up the wall in front of me and reach over and tap Stiles timidly on the shoulder. "Stiles….. We can't stay here." I whisper meekly causing him to turn around and look where I'm pointing.

"Scott, wait, not here." He yells staring at the windows and moving back away from them.

"What was that? Scott, what was that?" Allison panics trying to get her boyfriends attention. "What came out of the ceiling?"

"Will you just help me?" Scott yells back finally getting the milk machine against the door. "The chairs, stack the chairs."

"Guys…." I draw out turning to look at all of them rushing around grabbing items to stack against the door.

"Guys…. Can we just wait a second?" Stiles continues for me. "You guys, listen to me…" I wave my hands to try and get their attention but they just continue running around. "Can we wait a second? Guys? Stiles talking." I look over at him and mouth 'Are they deaf?' and he shakes his head before yelling a little louder. "Can we hang on one second, please? Hello!" Everyone spins around after putting the last nearby stack of chairs in place. "Okay, nice work. Really beautiful job, everyone."

"Have you guys been working on your Tetris skills?" I ask and Allison gives me a half amused, half scared look.

"Now, what should we do about the 20 foot wall of windows?" Stiles asks and we both step aside waving a hand at the wall in question. Scott sighs and drops his head in shame.

"Can somebody please explain to me what's going on, because I'm freaking out here." Allison answers shooting me a look that I answer with a shake of my head, before she turns to Scott clinging to his arm. "And I would like to know why. Scott?"

Scott extracts himself from her grip and goes to lean on one of the cafeteria tables. I gesture for Stiles to say something before hopping over to Scott's side.

"Somebody killed the janitor." Stiles steps towards the three of them explaining.

"What?" They all mutter.

"Yeah, the janitor's dead." I reach forward and place a hand lightly on Scott's shoulder.

"Scott, we need to do something." I whisper so just he can hear. "Scott talk to them."

"What's he talking about? Is this a joke?" Allison yells over at the two of us.

"What, who killed him?" Jackson demands stepping in front of Lydia.

"No, no, no, no. This was supposed to be over." Lydia shakes her head muttering. "The mountain lion killed…"

"No, don't you get it?" Jackson cuts her off yelling at her. "There wasn't a mountain lion."

I let go of Scott's arm after shooting him one last look before heading over to Allison's side.

"Who was it?" She asks me gripping my arm tightly. "What does he want?" She turns me towards her forcefully and whispers, "What's happening?" I shake my head not knowing what to say. "Scott!" She whirls in his direction shouting.

"I…. I don't know." Scott stammers turning towards us all. "I just…. If we go out there, he's gonna kill us."

"Us? He's gonna kill us?" Lydia squeaks out as Stiles steps closer to her to comfort her.

"Who? Who is it?" Allison asks turning to Stiles, seeing as no one else would answer her. Stiles looks confused as everyone's eyes rest on him and he turns to Scott who had gone back to leaning on the table.

"It's Derek. It's Derek Hale." Scott answers bringing my head wheeling around in shock.

"Derek killed the janitor?" Jackson asks angrily.

"Are you sure?" Allison asks waving me off of her when I look to her.

"I saw him." Scott responds to both questions and Lydia whispers 'The mountain lion….' Scott yells over his shoulder, "No, Derek killed them. Starting with his own sister."

"And the bus driver?" Allison looks at Scott.

"And the guy in the video store." Scott answers shooting me an apologetic look. "It's been Derek the whole time. He's in here with us." I glare over at Stiles silently asking him what Scott is doing, he shrugs over to me. "And if we don't get out now… He's going to kill us, too."

Jackson breathes in heavily through his nose before turning to Stiles. "Call the cops."

"No." Stiles answers not even looking at him.

"What do you mean, "No"?" Jackson snarls turning Stiles towards him.

"I mean no. You want to hear it in Spanish? ¡No!" Stiles snarks back and I push past Jackson and place myself between him and Stiles. "Look, Derek killed three people, okay? We don't know what he's armed with."

"Your dad is armed with an entire sheriff's department." Jackson tries to push past me to yell at Stiles. "Call him."

I shift my eyes over to Lydia who is digging in her purse to pull out her phone. "Lydia what are you doing?"

"I'm calling." She answers walking past us and dialling the three numbers deftly.

"No Lydia, would you just hold on a second?" Stiles says a lot softer than when he was talking to Jackson. He tries to walk around me to stop Lydia but Jackson grabs him and pushes him back towards the windows, bringing Scott over to stand by his friend.

"Lydia, just wait a second….." I reach out to pluck her phone from her hand and Allison stops me by grabbing my wrist and shooting me a look.

"Yes, we're at Beacon Hills High School." Lydia's voice shakes as she speaks. "We're trapped, and we need you to….." She stops and listens for a second. "But…" She listens again for a second before pulling the phone away from her ear and looking down at it.

"What's wrong Lydia?" I whisper lowering my hand back to my side.

"She hung up on me." She answers looking over her shoulder at me.

"The police hung up on you?" Allison asks sceptically.

"She said they got a tip warning them that there are gonna be prank calls about a break-in at the high school. She said if I called again that they're gonna trace it and have me arrested." Lydia says all in one breath before turning to Allison.

"Okay, then call again." Allison says pushing at the hand holding the phone.

"No, they won't trace a cell." Stiles cuts in pulling everyone's attention to him. "They'll send a car to your house before they send anyone here."

"What the… What…. What is this?" Allison stutters slightly crossing her arms over her chest. "Why does Derek want to kill us? Why is he killing anyone?" We all look around for an answer before all our eyes land on Scott.

"Why's everyone looking at me?" Scott asks looking over at Stiles.

"Is he the one that sent her the text?" Lydia asks scared.

"No." Scott answers immediately before pausing. "I mean, I don't know."

"Is he the one that called the police?" Allison digs further with her question.

"I don't know!" Scott yells annoyed causing Allison to turn away from him hurt.

I look over at her sadly but stay next to Scott and Stiles.

"All right, why don't we just back off the throttle here, yeah?" Stiles poses the question to all of us but places a hand on Scott's arm and pushes him off to the side and I follow them. As soon as I join them Stiles pats Scott's arm. "Okay, first off, throwing Derek under the bus, nicely done."

"I didn't know what to say. I had to say something. And if he's dead then it doesn't matter, right?" I chuckle at Scott's reasoning earning a glare from the three people behind us. "Except if he's not." Scott finishes with a sigh. "Oh, God, I totally just bit her head off." He looks over Stiles' shoulder at Allison with a groan.

"And she'll totally get over it." Stiles says bringing Scott's eyes back to him.

"Yeah, we get out of here, and I will talk to her….." I nod along with what Stiles is saying. "And I won't forget this time." Scott shoots me a small smile.

"Bigger issues at hand here," Stiles whispers harshly. "Like how do we get out alive?"

"Throw Jackson out the door and run the other way?" I suggest jokingly earning me a glare from Scott.

"We are alive. It could've killed us already. It's like it's cornering us or something." Scott growls out his eyes flicking between the two of us.

"Maybe he likes to play with his food first?" I suggest and Stiles lightly smacks my arm to get me to shut up.

"So what, he wants to eat us all at the same time?" Stiles asks and I shake my head.

"How is that any better than what I said?" I ask slightly peeved.

"No! Derek said it wants revenge." Scott cuts off whatever Stiles was going to say in response.

"Against who?" Stiles looks at Scott concerned.

"Allison's family?" Scott asks in response. I look over my shoulder at my friend and shake my head.

"Maybe that's what the text was about." Stiles muses making Scott give him a 'What?' look, "Someone had to send it."

"Okay, assheads. New plan." Jackson yells stepping towards us and bringing us spinning around. "Stiles calls his useless dad and tells him to send someone with a gun and decent aim. Are we good with that?"

"You know I'm liking my plan of throwing him out the door, better by the second." I mutter as Stiles runs a hand frustratedly over his head.

"He's right. Tell him the truth if you have to, just call him." Scott says to his best friend pleadingly.

"I'm not watching my dad get eaten alive." Stiles says after looking around at everyone with his jaw hanging open.

"All right give me the phone." Jackson grabs Stiles' shoulder and whips him around, and Stiles throws a punch which lands solidly on Jackson's nose. I cover my mouth with a gasp and try to hide my smile as Allison rushes over to check on Jackson. Stiles whips his phone out when Allison glares at him dialling a number

"Dad, hey, it's me. And it's your voicemail. Look, I need you to call me back now. Like, right now." We all jump when there is a loud banging coming from the door. Lydia yelps and quick steps over to Jackson as Stiles reaches for my arm and leads me to where everyone else is huddled. "We're at the school, okay? We're at the school."

"Oh, god. Oh my god!" Lydia exclaims as the pounding on the door gets more relentless. She grasps Jackson's sleeve like it was a lifeline.

Stiles glances over his shoulder at me before saying, "The kitchen, the door out of the kitchen leads to the stairwell."

"Which only goes up." Scott argues holding Allison against him.

"Up is better than here." Stiles urges me towards the rear of the cafeteria not taking his eyes off the door. Scott and the others remain huddled where they are.

"Unless you'd rather stay here and discuss with him which one of you he kills first." I hiss loudly waving a hand at the door as a hinge breaks loose. "Let's go!" That got everyone moving and racing through the door. Stiles and I were the last ones through and we could hear the thud of the door as it fell to ground behind us. We hurry down the hallway at the top of the stairs trying all the classroom doors, Lydia finds one leading into the chemistry room that opens easily and we all scamper in. Once everyone is in Scott grabs a stool and wedges it under the door handle which I look at amused.

Everyone stands there for a few seconds listening intently and we all suck in a breath when we hear snarling coming from right outside the door. Lydia looks around the room like she's ready to cry and I push off the desk I'm leaning on and walk over to her placing a hand lightly over her mouth. 'Shhhhh.' I whisper as quietly as I can in her ear feeling her tremble. I listen as the thundering footsteps retreat and breath out a sigh of relief releasing Lydia.

"Jackson, how many people can fit in your car?" Scott asks as soon as he's sure that we are all clear.

"Five, if someone squeezes on someone's lap." Jackson answers after a quick thought and I turn around counting the people in the room.

"Five? I barely fit in the back." Allison whispers loudly.

"It doesn't matter. There's no getting out without drawing attention." Stiles says from behind me.

"And besides there's six of us…. So unless someone is going to cling to the roof, we need a new plan." I pipe up making Jackson scoff.

"What about this?" Scott heads over to a door in the corner of the room. "This leads to the roof. We can go down the fire escape to the parking lot in, like, seconds." He plots looking between me and Stiles.

"That's a deadbolt." Stiles points at the lock with a frown.

"The janitor has a key." Scott says.

"You mean his body has it." I crinkle my nose at Stiles' statement before turning to Allison.

"Hey, you have a bobby pin?" I whisper to her pointing at her hair. She nods and pulls out two from under her hair and hand them to me. I nod my thanks and strip the little plastic piece on the end off before bending them into the shape I want.

"I'm getting the key." I hear Scott say as he pushes past Stiles.

"Are you serious?" Allison whispers blocking the door.

"Well, it's the best plan." Scott answers, "Someone has to get the key if we want to get out of here." I give a light smile to Stiles as he joins the group before pushing past him and heading to the door.

"You can't go out there unarmed." Allison hisses not budging from her spot. Scott looks around the vicinity and grabs the teacher's pointer capped with a foam finger before holding it like a bat in front of him. I raise my eyebrow questioningly as Stiles looks over at me rolling his eyes.

"Well, it's better than nothing." Scott says in regards to everyone's look at his choice of weapon. I stand up from where I was crouching in front of the door to the roof and join the group.

"There's gotta be something else." Stiles says taking a step to the side so he's not in my way.

"There is." Lydia answers nodding at the chemical cabinet behind Allison.

"What are we gonna do? Throw acid on him?" Stiles snarks at her and I place a hand on his arm shaking me head.

"No. Like a fire bomb." She gives him a look before pointing at the cabinet. "In there is everything you need to make a self-igniting Molotov cocktail."

"Self-igniting….." Stiles looks at me for clarification.

"Molotov cocktail." I finish for him before turning to Lydia with a grin. "You are brilliant." Everyone else just looks at her surprised.

"What?" She asks after sending me a half grin in thanks. "I read it somewhere." She says with a shrug.

"We don't have a key for that either." Stiles gestures at the cabinet in frustration. Jackson sighs and slams his elbow through the glass in the door of the cabinet.

"Apparently we do." I laugh walking over to the cabinet and helping Lydia gather the ingredients we need. I help Lydia for the next few minutes as she mixes up everything required.

"Jackson, hand me the sulphuric acid." She nods at the beaker sitting beside him as she pours in one of the last ingredients. Jackson passes it over and she hands the jar to me asking me to open it and pour it in. She picks up the beaker and swirls it around one last time before sticking a cork in the top and handing it over to Scott.

"No. No, this is insane, you can't do this. You cannot go out there." Allison's voice cracks from behind me.

"We can't just sit here waiting for Stiles' dad to check his messages." Scott retorts waving the hand with the Molotov cocktail in Stiles' direction. I reach across the counter and still his hand.

"You could die. Don't you get that? He's killed three people." Allison leans over my back whispering at Scott.

"And we're next. Somebody has to do something." Scott answers taking a step towards the door sliding out of my grip.

"Scott, just stop." Allison pleads with him. "Do you remember…. Do you remember when you told me you knew whether or not I was lying? That I had a tell. So do you." Allison starts to cry and her voice cracks even more and I watch sadly. "You're a horrible liar. And you've been lying all night. Just….. Just please…. Please don't go. Please don't leave us. Please."

Scott looks over at me. "Lock it behind me." I nod as an answer and push off the desk to follow him to the door. Allison stops him and pulls him into a kiss and I avert my gaze. As soon as Scott pulls away I reach out and wrap an arm around Allison's shoulders, Stiles slides past me and locks the door behind Scott. Allison turns in my arms and buries her head in my shoulder sniffling and I look just pat her back soothingly.

"He'll be fine." I whisper to her trying to calm her down.

"How can you be so calm?" She lifts her head and steps back wiping the tears from her eyes.

"I trust him." I shrug with a reassuring smile. "And if he says he will be back, he will be back."

Allison shakes her head and leans on the desk next to Lydia. "I don't know if I can trust him saying he will be back right now."

"Then trust me, alright?" I pat her hand lightly before turning and heading to where Stiles is hovering. "This is a really dumb idea." I hiss out so that only he can hear me.

"Well, at least it's an idea." Stiles shrugs before pointing at the door to the roof. "What were you doing?" I follow his gaze and head over to where I'd left the bobby pins in the lock of the door.

I start fiddling with the bobby pins and Stiles crouches down next to me. "Percy? What are you doing?" He watches my hands as I twist the bobby pins every now and then.

"Picking the lock?" I answer with a shrug and his jaw drops.

"You know how to pick a lock?" He blinks at me stunned before continuing, "How do you know how to pick a lock?"

"My dad taught me." I grin as he looks at me amazed. We hear Jackson behind us trying to comfort Allison. Stiles spins in his spot and sits down leaning against the wall next to me as I continue trying to get the lock open.

"Jackson, you handed me the sulphuric acid, right?" Lydia asks making me turn my head in their direction. "It has to be sulphuric acid. It won't ignite if it's not." She explains to the questioning look Allison gives her.

"I gave you exactly what you asked for, didn't I?" Jackson snarls at her earning a glare from both me and Stiles.

"Yeah. Yeah, I'm sure you did." She looks at the bottle that Jackson had handed her from across the room. I turn back to the door and try to lever the bobby pins into place when a loud growl rips through the air echoing off the walls. Stiles looks around and jumps to his feet one hand reaching down to me. Jackson falls to his knees groaning and I let go of the bobby pins but Stiles shakes his head holding me in place.

"Keep working on it. I'll check on him." He turns me back to the door lightly before jogging over to where Jackson is. Jackson starts screaming loudly and I turn in place watching as Stiles holds a hand up towards me telling me to stay. Lydia and Allison pull Jackson of the floor and he tries to shrug them off.

"Uh, no, I'm fine." He spins out of their grasps with a hand up to his head. "Like, seriously, I'm okay."

"That didn't sound okay at all." Allison says in response.

"What's on the back of your neck?" Stiles reaches up to point just above Jackson's jacket collar. Jackson swats his hand away violently before sighing.

"I said I'm fine." He grumbles out stepping away from Stiles and the others.

"It's been there for days." Lydia answers for him. "He won't tell me what happened."

"As if you actually care." Jackson takes a step threateningly towards her growling out. Stiles steps between them and Jackson stops short glaring at her over his shoulder.

"All right, can we not argue for half a second here?" Stiles tries to reason with Jackson as Allison looks worriedly at the door.

"Where's Scott? He should be back by now…." We all wheel around as we hear a click coming from the door. "Scott!" Allison rushes to the door and throws the stool holding it in place away before jiggling the handle trying to open the door. "SCOTT!"

"Where's he going?" Lydia asks joining her at the door.

"Scott." Allison starts pounding her fists on the door frantically. "Scott."

"Percy…. How are we doing over there?" Stiles looks over at me a little panicked as Allison continues her assault on the door.

"I've almost got it." I mutter out turning back to my task at hand.

"Stop. Stop!" Lydia screams at Allison making her freeze. "Do you hear that?" I ignore her as I continue moving the bobby pins trying to get them to click into place. The sounds of sirens reach my ears just as the bobby pins slide into place a turn the lock open. The door swings open in front of me and I sigh sliding to the floor to sit.

"Nice timing Percy." I whisper to myself staring at the door. Stiles stumbles over to me from where he was looking out the window at the cop cars. He looks between me and the door before sliding and arm around my shoulders and helping me to my feet.

We wait for about 10 minutes while the cops make there way to the room we are in and bust open the door. Lydia and Allison cling to each other as they are escorted from the room by a deputy, Jackson following behind them slowly. The sheriff comes into the room and sees his son and me before leading us from the room. Scott is in the hallway waiting for us and I weasel out of Stiles' hold and walk up to Scott and hug him.

"You okay?" I whisper and he nods in answer hugging me back. "Good." I pull back and let the sheriff lead us to the exit of the school.

"You sure it was Derek Hale?" He asks opening the door and letting me exit ahead of the boys.

"Yes." Scott responds with a little bit of attitude.

"I saw him, too." Stiles nods at his dad who in turn looks at me.

"Did you see him?" He asks me and I nod after the boys both shoot me a look.

"What about the janitor?" Scott asks the sheriff as we continue down the walkway of the school.

"We're still looking." Was the simple response.

"Did you check under the bleachers? Under them?" We all briskly descend the three steps as Scott prods the sheriff with more questions.

"Yeah, Scott, we looked. We pulled them out just like you asked, there's nothing." The sheriff calmly states.

"I'm not making this up." Scott whines at the man.

"I know, I believe you, I do." The sheriff turns to him as we reach the parking lot.

"No, you don't. You have this look like you feel bad for me. Like you want to believe me, but I know you don't." Scott sighs as he finishes. Stiles leans against the railing of the three steps we are stopped on and watches the interaction.

"Listen to me." The sheriff looks around the immediate area distractedly. "We're gonna search this whole school. We're gonna find him. Okay?" He punctuates his question by giving each of us a pointed look. "I promise."

"Sheriff!" A deputy calls from one of the cop cars stationed beside Stiles' Jeep.

"Stay." The sheriff points at Stiles then at me and Scott. "All of you."

"Well, we survived, dude. You know?" Stiles smiles at Scott once his father is out of earshot. "We outlasted the Alpha." Scott gives him an incredulous look. "It's still good, right? Being alive?" Stiles turns to me hopefully asking.

"When we were in the chemistry room, he walked right by us. You don't think that it heard us? You don't think it knew exactly where we were?" Scott asks and I run a hand through my hair.

"Well, then how come we're still alive?" Stiles asks sliding down a little on the railing so I could sit beside him.

"It wants me in its pack." Scott half yells and I glance over my shoulder to make sure no one else heard. Scott sighs as a deputy walks by us and shoots us a glance. I raise my hand in an awkward wave and he continues on his way. "But I think, first…." Scott continues once the man is no longer near us. "I have to get rid of my old pack."

Stiles looks at me to see if I understood what he meant and I shake my head in confusion. "What do you mean? What old pack?" Stiles asks turning back to his friend.

"Allison. Jackson, Lydia. You two." Scott lifts a hand slightly in our direction.

"The alpha doesn't want to kill us." I slide off the railing and sigh.

"He wants me to do it." Scott finishes Stiles' thought turning away from the two of us. "And that's not even the worst part."

"How in holy hell is that not the worst part, Scott?" Stiles yells shaking his head. I place a hand on his arm giving him a look telling him to quiet down.

"Because when he made me shift….." Scott stops again as the deputy walks back by us towards the other police cars. "I wanted to do it. I wanted to kill you. All of you." Scott looks away dejectedly.

"It doesn't matter." I whisper bringing both their faces towards me.

"What do you mean it doesn't matter?" Stiles hisses at me.

"It… Does….. Not…. Matter." I enunciate slowly before turning to Scott. "You may have wanted to kill us, but you didn't." Stiles looks at me exasperated. "That's all that matters to me. The fact that something in you stopped you from hurting us."

"But…" Scott starts and I hold a hand up to stop him with a weak smile.

"It doesn't matter." Scott holds my gaze for a second before nodding with a smile. We stand there in silence for a minute before Scott looks off to Stiles' right and heads over in that direction. I wrinkle my brow in confusion as we reach an ambulance and see Deaton sitting there.

"How…" Scott breathes out looking shocked at his boss. "How did you…."

"Get out?" Deaton finishes for him with a light chuckle. "Not easily. And from what they tell me, I'm alive because of you. I think I owe you a raise."

"Percy helped." Scott pointed his thumb over his shoulder at me and I waved awkwardly.

"Well thank you." Deaton nods at me as the sheriff appears behind me placing a hand lightly on my shoulder.

"Guys, come on, let's let the EMTs do their job. You can talk to him later." He leads me away from the ambulance with a hand on my back grabbing his son by the arm and dragging him along. Scott follows us after waving a goodbye to his boss. I look around as we are walking across the parking lot and see Allison walking away. I reach behind me and tap Scott lightly on the arm before nodding at her.

"Allison!" Scott races off after her after thanking me. I watch for a second then join the sheriff and Stiles where they are looking at the hood of the Jeep.

"How's the Batmobile, Robin?" I joke looking over his shoulder at the bent hood. Stiles looks at me trying to be angry but cracking a smile. "It can be fixed." I point over to where Scott and Allison are standing. "I'm not to sure about that though."

"You two stay here. I'm going to check on a few details and then I'll take you home." The sheriff knocks on the only unbent part of the Jeep's hood to get our attention.

"Next time we take your car." Stiles grumbles over to me leaning closer to the damage and groaning.

"We'll see about that." I shake my head and keep and eye on Scott and Allison who seem to have gotten into a pretty heated argument. Allison stops Scott mid sentence then shakes her head and walks away and Scott stares after her longingly before turning and shuffling back to us. I meet him halfway and he stops never bringing his eyes off the ground. "That didn't go well did it? Do you want me to go….." Scott cuts me off by pulling me into a hug and I just hug him back realizing that he didn't want to talk.
