"He wants you to tap into your animal side and get angry?" Stiles questioned as he and his friends made their way to lunch.

"Yeah.", Scott said.

"Well, correct me if I'm wrong, but every time you try to do that, you try to kill someone and that someone's usually us.", Stiles said.

"I know.", Scott muttered, not paying attention. He seemed to be looking at Allison with a lovesick expression. Sam frowned in realization. "Please tell me you didn't."

"I didn't what?", Scott asks, confused.

"You did!"

"I did what?"

"You went over to Allison's last night, didn't you? Dammit Scott, how're you gonna be able to move on if she's still your number one distraction? I'm snitching.", she threatened.

He narrowed his eyes at her. "You better not."

Stiles looked confused. "You're supposed to stay away from Allison?"

"Derek says he doesn't even know if he can teach me anyways.", Scott told Stiles. "I have to be able to control it."

"Well, how is he going to teach you?", Stiles asked.

"I don't know.", he responded, glumly. "And I don't think he does either."

"Okay, when are you seeing him again?"

"Just told us not to talk about it.", Scott said. "Just act normal and get through the day."

"When?", Stiles asked.

"He's picking us up at the animal clinic after school.", Sam said.

"After school.", Stiles muttered. "Ok, well, that gives me till the end of the school day then."

"To do what?", Scott asked.

"To teach you myself."

It was finally the end of the day and Stiles, Scott and Sam headed out to the empty lacrosse field.

"Okay,", Stiles sighed as he dug through his bag. "Now. . . put this on, Scott." He handed him a black belt.

"Isn't this one of the heart rate monitors for the track team?"

"Yeah, I borrowed it."

"Stole it.", Sam muttered.

"Temporarily misappropriated.", Stiles corrected. "Coach uses it to monitor his heart rate with his phone while he jogs and you're gonna wear it.", he told Scott.

"Isn't that Coach's phone?", Scott pointed.

"That I stole."

"Why?"

"All right, well, your heart rate goes up when you go wolf, right? When you're playing lacrosse, when you're with Derek, whenever you get angry. Maybe learning to control it is tied to learning how to control your heart rate."

"Like the Incredible Hulk."

"Kind of like the incredible hulk, yeah."

"No, I'm like the incredible hulk."

"Would you shut up and put the strap on?", Sam ordered.

Scott sighed and tied the strap around his waist as Stiles pulled out duct tape from his bag. He went behind Scott's back and tied his hands together.

"I'm feeling off about this.", Scott mutters.

"Don't make it weird.", Stiles said as he walked back over to the bench.

Stiles grabbed his lacrosse stick and a bag of lacrosse balls and went to the middle of the field.

"All right, ready?"

"No."

"Remember, don't get angry."

"I'm starting to think that this is a really bad idea.", Sam muttered.

Stiles scooped up a ball into his stick and slammed it at Scott's stomach. Sam flinched as Scott groaned in pain.

"Is this really necessary?", Sam asked as the next one hit him in the left shoulder. "Okay, that one kinda hurt.", they hear Scott say.

"Quiet, remember you're supposed to be thinking about your heart, all right? About staying calm."

"Staying calm. Staying totally calm. There's no balls flying at my face."

Sam winced as another ball hit Scott in the right shoulder. Another hit him right below the rib cage. "Aah! Son of a bitch!"

"You know what? I think my aim is actually improving."

"Wonder why.", Scott and Sam say.

"Ah, bup, bup," Stiles warned, looking at the phone on the ground. "Don't get angry."

"I'm not getting angry.", Scott growled out before letting out a cry of pain once again. Another one hit him in the left shoulder.

"Stiles, stop, just wait. Hold on."

The next one hit Scott in the chest and he fell to the ground.

"Scott…?"

Sam and Stiles watched him break the tape that bonded his hands and growl lowly.

After a while, he rolled onto his back and looked up at Stiles and Sam and gave one last groan of pain.

His eyes flickered back to their normal color. "Scott, you were changing.", Stiles stated.

"From anger. But it was more than that. It was like the angrier I got, the stronger I felt."

"So it is anger then. Derek's right."

Sam sighed and shook her head. This is gonna take a while.

Stiles and Sam met up with Scott in front of the school.

"Since I can't spend time with Allison, I'm gonna need your help.", Scott said to Sam. Sam shrugged in acceptance.

Stiles ran ahead of them. "Ok, ok, stay here. Do you have your keys?", he asked Scott.

Scott pulled out his keys.

"Perfect. Hold them up like so.", Stiles said. Scott held up his hand, gripping a key. "Sam, you might want to step back."

Sam stepped back in confusion and leaned up against the school wall. "Now, whatever happens, just think about Allison. Try to find her voice like you did at the game. Got it? Ok. Just. . . keep holding it right there." Stiles pulled out his keys and slowly walked over to a black truck and forcefully dragged his keys across the side, making an awful screeching sound.

Stiles got to the end of the truck and turned to face his friends with a smirk and stuffed his keys back into his pocket. "Hey, hey, hey, dude! What do you think you're doing to that truck, bro?", he exclaimed in faux shock.

Sam and Scott's eyes widened.

A group of guys turned and faced Scott and stormed to him. A guy threw a punch at Scott, and he fell to the ground. Sam scooted around the group and walked over to Stiles. "This your idea of getting him to control himself?"

"I know, great, right?", he smiled.

The group surrounded Scott and started kicking him and punching him until Mr. Harris broke up the fight.

"Stop! Hey, stop it right now!" Mr. Harris yelled at the group. The group angrily left, and Mr. Harris hovered over Scott. "What do you idiots think you're doing?"

Sam frowned as she sat in detention between Stiles and Scott and rested her chin in her palm. "You guys are idiots.", she grumbled.

"Excuse me, sir." Scott called Mr. Harris who sat at his desk. "Uh, I know, this is detention and all but uh, we're supposed to be at work and I don't know about Sam, but I don't want to get fired."

Mr. Harris continued to ignore him and continued to play on his ipad. "You knew I would heal.", Scott grumbled to Stiles.

"Yep.", Stiles answered.

"So you did that to help him learn?", Sam said.

"Yep."

"But partially to punish me.", Scott said.

"Yeah. Well, that one's obvious."

"Can you guys, like, not get on each other's nerves by being unnecessarily petty and irritating? It's stressful.", Sam says.

"I'm not angry anymore.", Stiles said. "Look, you have something. Ok? Whether you want it or not, you can do things that nobody else can do. So that means you don't have a choice anymore. It means you have to do something."

"I know.", Scott said. "And I will."

"Ok," Mr. Harris called to the trio. "You three, out of here."

"Oh, thank God.", Sam said as she gathered up her stuff and raced out the room with her friends.

They walked into the clinic and followed behind Scott as he rushed to the back room.

"What are you doing?", they heard Scott cry out. Stiles and Sam saw Derek holding a man up in the air who was tied to a chair.

"Scott! Sam! Get out of here!" The man yelled over his shoulder. Derek was holding Scott's boss. The hell?

Derek dropped him and punched him in the face, knocking him out. Sam raced over to Derek and placed her hands on his chest and pushed him back.

"Stop! Stop!", Sam yelled. "What the hell are you doing?"

"Look, when he's conscious he can keep himself from healing, but unconscious, he can't.", Derek said, pushing past her and back to the man.

"Are you out of your mind!?", Scott asked. "What are you talking about?"

"You want to know what the spiral means, Scott?", Derek asked. "It's our sign for a vendetta, for revenge. It means he won't stop killing until he's satisfied."

"You think he's the Alpha?", Sam asked in disbelief.

"We're about to find out.", Derek raised his right arm, pushing her out of the way and was about to swing back down at Scott's boss when Scott wolfed out and grabbed his arm in a vice.

Scott growled at Derek and pushed his arm away. Scott relaxed and slowly began to return to his normal self.

"Hit him again and you'll see me get angry.", Scott threatened Derek.

Sam sat on the medical table while Derek paced the back of the room and Scott cleaned the cut on his boss's face.

"Do you have a plan?", Derek asked Sam.

"Give me an hour.", Sam said.

"Then what?"

"Meet us in the school in an hour and we'll go from there.", she says.

An hour later, Sam stepped out of the Stiles' jeep and looked around to see an empty parking lot.

"This is a terrible idea.", Stiles said.

"Yeah, I know.", Sam said.

"But we're still gonna do it?"

"You have another option?", she asked.

"Well, personally I'm a fan of ignoring a problem until it eventually just goes away."

"Just make sure Scott can get inside.", Sam pointed at the school, annoyed.

Stiles reached into the back of his jeep and took out some big pliers. Headlights flooded lit up their bodies and they looked to see the Camaro park in front of them. Derek got out and Sam walked over to him.

"Where's his boss?", she asked.

"He's in the back. Relax.", he says, rolling his eyes. She looked past Derek and into the backseat to see Alan still passed out and tied up.

"Oh, he looks comfortable.", Stiles said, sarcastically. He and Scott start walking up to the school.

"Wait. Hey. What are you doing?", Derek called after them.

"You said I'm linked with the Alpha.", Scott said. "We're going to find out if you're right."

Sam sighed and stood near the jeep with Derek. "This is gonna bite me in the ass so bad.", she heard Derek mutter, annoyed.

They stood for a while before jumping at the sound of a loud strangled noise. "Please don't tell me that's what I think it is.", Sam said, bewildered.

Derek looked irritated. "You have got to be kidding me."

A few minutes later another sound came through the speakers. This one sounded like a beast growling. They looked at the school as it seemed to rumble at the loud noise.

After a while, they saw Stiles and Scott coming out of the building.

"I'm going to kill both of you.", Derek growled at them. "What the hell was that? What are you trying to do, attract the entire state to the school?"

"I didn't know it would be that loud.", Scott said, smiling.

"Yeah, it was loud." Stiles chuckled. "And it was awesome.", he sang.

"Shut up.", Derek said.

"Don't be such a sour wolf.", Stiles said. Sam shook her head at their childishness. A low growl entered her ears and she quickly looked at Derek, but he was looking at her with furrowed eyebrows too. It was him...

"What did you do with him?", Scott asked, looking into Derek's car. They looked as well and saw Alan gone.

"What?", Derek questioned him. "I didn't do anything."

Suddenly, Derek started spitting up blood before being lifted into the air.

"Derek!", Sam shrieked in shock.

"Sam, let's go!" Stiles said, grabbing her hand and pulling her to the school.

"No! We have to help him! We have to help him!" It took both Scott and Stiles to drag her into the school and they locked the doors behind them.

Sam panted in panic. "We're just gonna leave him!?"

Stiles turned to Sam. "He's dead regardless. We have to save ourselves now!"

They looked down the dark, empty school hallway, jumping at the sound of a distant howl somewhere in the building. They all looked at each other and bolted into a classroom. "The desk." Scott and Sam grabbed the front desk and began to push it up against the door, but Stiles stopped them.

"Shh, stop, stop.", he said. Scott and Sam stopped and looked at him, pausing to hear a noise. "The door's not gonna keep it out."

"I know.", Scott said.

"I hate your boss.", Stiles said.

"What?", Sam asked, looking at Stiles.

"Deaton, the alpha? Scott's boss.", Stiles said.

"No.", Scott said.

"Yes.", Stiles disagreed. "Murdering psycho werewolf."

"But how??.", Sam asked.

"Oh, come on.", Stiles said. "He disappears and that thing shows up ten seconds later to toss Derek twenty feet through the air? That's not convenient timing?"

"It's not him.", Scott said.

"He just killed Derek.", Stiles argued.

"No, Derek's not dead.", Sam said, glaring at Stiles. "He can't be dead."

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

"Ok, just...", Scott paused, taking a deep breath. "What do we do?"

"We get to my jeep, we get out of here, and you seriously think about quitting your job, sound good?", Stiles said. They walked over to the windows and Scott tried to open one.

"They don't open.", Sam said, realizing the problem. "The school's climate-controlled."

"Then we break it.", Scott said.

"Which will make a lot of noise." Stiles warned.

"Then. . . ", Scott trailed off as he looked around. "Then we run really fast. Really, really fast." Sam looked at him in disbelief before looking at the window and at the jeep. It was kinda far.

Actually…

When she looked at the jeep, she noticed something about the hood. The side of it seemed to be bent inward.

"Stiles, what's wrong with the hood of your jeep?", she asked, getting his attention.

"What do you mean?", Stiles asked, looking at her. "Nothing's wrong."

"It's bent."

"Like, dented?", Stiles asked her.

"No, she means bent.", Scott emphasized, his eyes widening.

"What the hell?", Stiles said. A crashing sound of glass sounded to the left of them, and they sunk to the floor and covered their heads. They looked up and saw Stiles' car battery in the middle of the floor.

"That's my battery.", Stiles whimpered in anger, standing back up. Sam grabbed his hand and yanked him back down. "Stop.", Sam hushed.

"We have to move.", Stiles said.

"He could be right outside." Scott said.

"He is right outside.", she growled at him. "Just let me take a look."

Sam slowly got to her knees and peeked out the window and looked around the parking lot.

Nothing.

"Anything?", Stiles asked.

"No.", she answered.

"Move now?", Stiles asked. She nodded.

"Okay.", Scott said. They walked out the room. Scott and Sam moved to turn right but Stiles stopped them.

"Somewhere without windows.", he said.

"Every single room in this building has windows.", Scott said, hushed.

"Or somewhere with less windows.", Stiles corrected.

"The locker room.", Sam suggested.

"Yeah.", Stiles agreed. They made their way down the hallway and slipped into the locker room.

"Call your dad.", Scott told Stiles.

"And tell him what?", he questioned him.

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

"What if it doesn't? What if it goes completely terminator and kills every cop in sight, including my dad?", Stiles growled at him.

"They have guns."

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

"Then we... " Scott tried to think of another plan. "We have... We have to find a way out and just run for it."

"There's nothing near the school for at least a mile, Scott.", Stiles said.

"What about Derek's car?", Scott said.

"He has his keys with him.", Stiles said.

"Okay so we sneak to his body and get the key."

"And him.", Sam says.

"Fine.", Stiles agreed. "Whatever."

They walked back to the door and Stiles made a grab for the door, but Scott stopped him.

"What?", Stiles asked, paranoid.

"I think I heard something."

Sam looked around, keeping quiet for a sound.

"Like what?", Stiles asked.

"Shh- Shut up.", Sam snapped.

They all began backing away from the door.

"Hide."

Stiles went over to a locker, opened it and stuffed himself inside.

"Stiles-" Sam sighed and stuffed herself into a locker along with Scott.

She closed the door as the door to the locker room opened. They waited in silence until a man opened Sam's locker, making her scream. Her scream scared the older man and she stopped screaming when she realized the man was the janitor. "Son of a bitch.", the older man muttered.

"Quiet.", Stiles hushed, coming out of his locker along with Scott.

"Quiet my ass, what the hell are you trying to do, kill me?", Janitor growled. "The three of you, get out."

"Just listen for half a second, ok?", Stiles urged.

"Not ok.", Janitor growled at them, pushing them out the door. "Get the hell out of here right now."

"God, just one second to explain.", Stiles said.

"Just shut up and go.", the janitor pushed and was suddenly pulled back into the locker room.

The door slammed shut. They stood in shock as they heard a loud thud and saw blood spilling under the door.

"Can we run now?", Stiles whimpered.

They raced down a hallway to the back doors of the school and pushed them, but they wouldn't budge.

"What the hell?" Stiles growled. Sam peeks through the crack and saw dumpsters in the way.

"It's the dumpsters.", Sam exclaimed, frustrated.

"He pushed them front of the door.", Stiles realized.

"To block us in.", Scott said, backing away.

"Come on, help me." Stiles grunted as he slammed his body against the door.

"Come on, Stiles.", Sam said, grabbing him as they walked down another hallway.

"I'm not dying here.", Stiles said. "I'm not dying at school."

"We're not going to die.", Scott declared.

"God, what is he doing?", Stiles whined. "What does he want?"

"Me.", Scott said. "Derek says it's strong with a pack."

"Yeah, great.", Stiles muttered, rolling his eyes. "A psychotic werewolf who's into teamwork. That's... that's beautiful."

As Stiles continued muttering, Sam stopped by a window and looked out of it to the other side of the building's roof. Her eyes widened as she saw a large figure standing on top of it staring at them. It knows. The boys turned around, seeing their friend paused in fright.

"Holy shit.", Sam muttered, backing away. They quickly pulled her away, bolting down the hall as the beast crashed into the windows, racing after them.

They sped up at the sound of a growl behind them and heavy paw steps that pounded behind them.

They slammed through some doors and ran down two flights of stairs to the basement. They stopped and took a breath. "We have to do something.", Stiles panted.

"Like what?", Sam asked, huffing.

"I don't know.", Stiles said. "Kill it, hurt it, inflict mental anguish on it… something."

They heard a loud thump and ran to the other side of the basement, up the stairs and back to the first floor.

Sam stopped, trying to catch her breath as she heard a familiar ringtone. She looked down the hallway. "Wait."

"What?", Scott asked, panting.

"Do you hear that?", she asked.

"Hear what?", Stiles questioned. As they quieted themselves, they could faintly hear a ringtone. "It sounds like a phone ringing.", Sam said.

"What?"

"I know that ring.", Scott said, his eyes widening in horror. "It's Allison's phone."

Stiles grabbed his phone and handed it to Scott. Scott dialed Allison's number and put it on speaker phone.

"Stiles?", Allison's voice answered.

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

"I'm in the school looking for you. What, were you at my place?", she asked.

"Where are you right now?"

"On the first floor."

"Where? Where are you exactly?"

"The swimming pools."

"Get to the lobby. Go now."

"Ok, ok, I'm coming." Scott hung up and they ran to the lobby and met up with Allison.

"What are you doing here? Why did you come?", Scott pressed Allison.

"Because you asked me too.", Allison said, confused.

"I asked you to?", Scott asked, fearfully.

They all looked at each other in shock. Sam frowned in realization. Derek smashed his phone the other day… The alpha must've found it...

Allison held up her phone and Stiles and Sam read the text over Scott's shoulder. 'Meet me at the school. Urgent. Scott.'

"Why do I get the feeling you didn't send this message?", she asked, worried.

"Because he didn't.", Sam said. "Der- I mean, someone smashed his phone into a wall."

"Did you drive here?", Stiles asked.

"Jackson did."

"Jackson's here too?", Scott asked, grasping his head, mortified.

"And Lydia, what's going on? Who sent this text?", Allison's phone rang and she answered it. "Where are you?"

The door to the lobby opened and Jackson and Lydia appeared.

"Finally.", Lydia sighed. "Can we go now?" A heavy thud sounded above them. Sam started pushing Stiles and Scott, "Run.", she ordered. "Run!!"

The teens all ran up the stairs and the thing followed them. They quickly ran into a room, having Scott closed and locked the doors behind them. Sam looked to her left to see large windows, dropping her shoulders in disbelief.

Oh, for fuck's sake.

"Help me get this in front of the door.", Scott told Jackson as they pushed a stack of chairs in front of the door.

"Scott, wait, not here.", Sam said. He ignored her.

"What was that?", Allison asked. "Scott, what was that?"

"What came through the ceiling?", Lydia whined.

"Would you just help me?", Scott snapped. "The chairs, stack the chairs."

"Guys, stop!", Stiles called them. "Hello!", Sam yelled. They stopped working and looked at her.

"Ok," Sam started. "Look, that's perfect and all but what do we do about the twenty-foot-tall windows?"

"Can someone please just explain to me what is going on because I am freaking out.", Allison said, her voice shaking. "And I would like to know why. Scott?"

Scott walked away from the group and buried his head in his hands as he thought of something. He looked to Stiles for help.

"Somebody killed the janitor.", Stiles said, bluntly. Sam looked at him with wide eyes. That wasn't the smartest thing to say in the moment.

"What?", Lydia asked, shocked.

"Yeah, the janitor's dead.", Stiles clarified.

"What is he talking about?", Allison asked as she looked at the trio. "Is this a joke?"

"What, who killed him?", Jackson asked.

"No, no, no, no. This is supposed to be over.", Lydia said. "The mountain lion killed..."

"Don't you get it?", Jackson asked Lydia. "There wasn't a mountain lion."

"Who was it?", Allison asked, angrily. "What does he want? What's happening? Scott!"

"I don't know!", Scott finally spoke. "I just... If we go out there, he's gonna kill us."

"Us?", Lydia asked. "He's gonna kill us?"

"Who?", Allison asked. "Who is it?"

"It's Derek.", Scott said. Sam's jaw dropped as she snapped her attention to him. No way.

"It's Derek Hale.", Scott lied.

Sam looked at Stiles with a dead look as he looked back at her weakly.

"Derek killed the janitor?", Jackson asked.

"Are you sure?", Allison asked.

"I saw him.", Scott said.

"The mountain lion...", Lydia said.

"No, Derek killed them.", Scott told her sternly.

"All of them?", Allison asked.

"Yes, starting with his own sister. It's been Derek the whole time. If we don't get out now, he's gonna kill us too."

Sam couldn't believe Scott. She understood trying to make them not believe in the damn near 20-foot monster, but for him to blame it on someone who was already dead…

"Call the cops.", Jackson said.

"No.", Stiles said.

"What do you mean no?"

"I mean no. Do you want to hear it in Spanish? Noh."

"Look, Derek killed three people.", Scott said, glancing at Sam. "We don't know what he's armed with."

"You have got to be shitting me...", Sam muttered under her breath, turning away from him.

"Your dad is armed with an entire sheriff's department. Call him.", Jackson said.

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

"No, Lydia, wait a second.", Stiles warned as she walked away from the group and held the phone up to her ear.

Jackson stepped in front of Stiles and shoved him back. Sam stepped in front of Jackson and shoved him back and when Jackson made another move towards her, Scott stepped forward and stopped him.

"Yes, we're at Beacon Hills High School.", Lydia said. "We're trapped and we need you to…But-", Lydia took the phone from her ear and turned back to us in shock. "She hung up on me."

"Say what-?", Sam's eyes widened.

"The police hung up on you?", Allison questioned her.

"She said that they got a tip saying that there would be prank calls about a break into the high school.", Lydia explained. "She said if I called again, they're gonna trace it and have me arrested."

"Then call again.", Allison said.

"No, they won't trace a cell.", Stiles said. "They'll send a car to your house before they'll send anyone here."

"What the... what...", Allison stuttered. "What is this? Why does Derek want to kill us? Why is he killing anyone?"

Jackson, Lydia and Allison looked at Sam. Then Sam looked at Stiles who looked at Scott.

"Why's everyone looking at me?", Scott asked.

"Is he the one that sent her the text?", Lydia asked him.

"No.", Scott said. "I mean, I don't know."

"Is he the one who called the police?", Allison asked.

"I don't know!", Scott yelled at Allison in frustration and Allison shrunk back in fear.

"All right," Stiles said. "Why don't we just back off the throttle here, yeah?"

Stiles grabbed Sam's arm, pushing Scott and pulled Sam to the other side of the room. "Ok, throwing Derek under the bus, nicely done.", Stiles said.

"Yeah, and when or if we get out of here alive, I'm whooping your ass before Derek can get to you.", Sam threatened.

"I didn't know what to say.", Scott said. "I had to say something. And if he's dead then it doesn't matter, right?"

"So that just makes it okay, Scott? Really??", Sam asked with wide eyes, stepping up to him.

Stiles pushed her back. "Easy there, Sam."

"Look, why do you care so much?", Scott asked.

"Uh, because I've been out busting my ass to get you some help so you can sort this out in order to live a semi normal life again. Right now, you're fucking that up.", Sam hissed.

"Okay, let's say he's not dead.", Scott paused.

"Okay then, he's gonna kick your ass. With every right, because now you have them thinking he's hunting us down and he's supposed to be dead.", Sam said.

Scott's eyes widened. "Oh, God, I just totally bit her head off.", Scott said, completely ignoring her. Sam gave Stiles a threatening look who got the hint and looked at Scott.

"And she'll totally get over it.", Stiles said. "Bigger issues at hand here, like how do we get out of here alive?"

"But we are alive. It could have killed us. It's like it's cornering us or something.", Scott said.

"So what, he wants to eat us all at the same time?"

"No, Derek said it wants revenge.", Sam said.

"Against who?", Stiles asked. Sam frowned. If Derek knew the intentions of the alpha and why it wanted revenge... Maybe whoever the alpha knew got killed by...hunters...

Sam glanced at Allison and her eyes widened. Argents.

"Allison's family.", Sam said in shock, making the boys look at her in shock as well.

"Maybe that's what the text was about.", Stiles said in realization. "Someone had to have sent it."

"Ok, assheads," Jackson said behind them. The trio turned and looked at him. "New plan. Stiles calls his useless dad with a gun and hopefully he'll have some decent aim. Are we good with that?", Jackson meanly suggested.

Sam looked at him in annoyance. "Really, Jackson?"

"He's right.", Scott said. Sam looked at him in disbelief and pointed at the boy. "You know, you're walking on thin fucking ice with me tonight.", she growled at him.

"Tell him the truth if you have to, just call him.", Scott told Stiles.

"I am not watching my dad get eaten alive.", Stiles said, looking at Scott with wide, conflicted eyes.

"Me either.", Sam agreed.

"All right, give me the phone.", Jackson ordered, readying to push past Sam to get at Stiles. Once Jackson laid a hand on Sam's shoulder, the girl turned around and threw a punch, squaring her fist in Jackson's nose.

"Did you forget to keep your hands to yourself?", Sam growled asked as he fell to the ground and Allison rushed over to him. Lydia and Scott looked at them, amused while Stiles stepped in front of Sam, blocking her from Jackson as he pulled his phone out and hurriedly called his dad.

"Hey, Dad, it's me.", he said, letting out a frustrated sigh as he got his father's voicemail. "And it's your voicemail. Look, I need you to call me back now. Like right now."

Something banged on the door, and they backed up to the other side of the room as the door kept rattling. "We're at the school. Ok? We're at the school.", Stiles hung up and stuffed his phone back into his pocket. Screws began to push out of the door hinges.

"Where do we go?", Stiles asked. "Where do you go to hide, Sam?"

"Why the hell are you asking me?", Sam asked, incredulously.

"Because you know the school exits and hideouts by heart."

"And you expect me to magically whip the map out right now?", Sam looked at him with wide eyes.

"Yes! Think Sam!"

Sam sighed harshly, thinking. The closest place she could think of would be...

"The kitchen.", Sam said. "The door out of the kitchen leads to the stairwell."

"Which only goes up.", Stiles said.

"Up is better than here right now.", Sam said. They turned and ran into the kitchen, climbed the stairs to the second floor and ran into a classroom.

Once they closed the door, Scott and Sam placed their ears up against the door and listened to heavy footsteps pass the door, with a low growl.

"Jackson, how many people can fit in your car?", Scott whispered to Jackson.

"Five, if someone squeezes on someone's lap.", Jackson answered.

"Five?", Allison asked. "I barely fit in the back."

"I can take Derek's car.", Sam said.

"Derek's car?", Jackson questioned her.

"Absolutely. You got a better idea?", Sam expressed with raised eyebrows.

"It doesn't matter.", Stiles said. "There's no getting out of here without drawing attention."

"What about this?", Scott asked, walking to a door. "This leads to the roof. We can go down the fire escape and get to the parking lot in like seconds."

Sam walked over to the door and saw the lock.

"That's a deadbolt.", Sam said, looking at him, irritated.

"The janitor has the key.", Scott said.

"You mean his body has it.", Stiles corrected, coming over to them.

"We can get it.", Scott whispered to Stiles. "We can find him by scent, by blood."

"Well, gee, that sounds like an incredibly terrible idea.", Stiles said. "What else you got?"

"I'm getting the key.", Scott said. "Sam, you're coming with me."

Sam took a deep breath in frustration. "You owe me so much.", she told him. Scott pushed past Stiles to Allison. Sam walked over to the door and waited for him.

"You can't go out there unarmed.", Allison said.

"I got Sam. She knows every inch of this school." Scott said.

"You can't go out there unarmed.", Allison repeated, ignoring him.

"I got something.", Lydia said. She looked at the chemistry cabinet.

"What are we going to do?", Stiles asked. "Throw acid on him?"

"No.", Sam said, smiling. "A firebomb." For once, Lydia's smarts proved useful.

"Exactly.", Lydia agreed. "In there is everything you need to make a self-igniting Molotov cocktail."

Sam grabbed some stuff from the cabinet and handed it to Lydia as she began mixing stuff in a chemistry bottle.

"Jackson, hand me the sulfuric acid." She poured the acid in and shook it around before putting a cap on and handing it to Sam.

"No, this is insane.", Allison disagrees.

"We can't just wait around here waiting for Stiles to check his messages.", Scott countered.

"You could die. Don't you get that? He's killed three people."

"And we're next. Somebody has to do something. Come on, Sam." Sam walked to the door, shrugging at Allison before they left. They turned left down the hallway. Switching hands to hold the Molotov, she slapped Scott behind his head with her free hand.

"Why?", he asked, rubbing behind his head.

"You know exactly what that was for. Go." They walked down two flights of stairs to the first floor.

Her heart dropped as she paused. "Scott, wasn't the janitor in the locker room?"

"Yeah."

"Well, shouldn't we be heading the other way?", she asked.

"My nose is leading to this direction."

"But this leads to the auditorium.", Sam says, unsure. "His body was in the locker room."

He couldn't have dragged him here… could he?

"Let's just go.", Scott said. Sam sighed. They looked around as they made it into the auditorium. It was big with a few emergency lights on, but it was still dark and cold. Scott walked over to the bleachers and looked under them. "There."

"Let me go.", Sam says.

"What, why?", Scott asks with wide eyes.

"Uh, I'm still human and he's not after me. So, take this."

Sam handed the Molotov to Scott and walked under the bleachers, using her hands to feel her way through.

She paused as she heard something creak and quickly snapped her attention to Scott who was still in the spot she left him.

What the hell was that.

Sam shook her head and walked faster. Suddenly something dripped down on her face, causing her to stop and wipe it off. It felt sticky.

She looked at her palm, and despite the dimly moonlit auditorium, she saw a darker streak on her palm and a familiar scent of metal filled her nose.

She closed her eyes, fearfully. "Fuck…", she whimpered to herself before looking up from under the bleachers.

She gaped in horror at the scene of the Janitor's mauled body. His face torn, blood coating his blue uniform, mouth opened as if he was still screaming, his eyes were opened and rolled back.

She let out a shaky sigh, slowly reaching into his pocket and pulled out his keys.

She looked to her left and saw the bleachers, one by one, move towards her. Her eyes widened; the bleachers were closing. She rushed back, jumping over moving bars and almost getting caught in between the bleachers.

Scott ran over to her, catching her in his arms. "You ok?"

"Yeah. Was that you?", she asked, upset.

His eyes widened. "No."

They heard a growling and looked to the middle of the room to see a large black beast on all fours with blood red eyes.

"Shit."

The beast rushed at them, shaking the floor. Scott threw the Molotov and the bottle crashed on its head. Alpha stopped but the Molotov didn't ignite.

Shit.

"Damn it.", Scott cussed as the Alpha began to race towards them again, but they turned to run.

Before either of them could leave the auditorium, something grabbed their ankles, making them falls and turned over on their backs to see the Alpha hovering over them, its pearly white teeth shining from the moon light. The Alpha let out a bellowing howl that shook the entire school and made Sam cover her ears in pain. She waited for the pain of being bitten or eaten but laid in silence. Her eyes opened. The alpha was gone and so was Scott.

She quickly sat up and looked around for Scott. "Scott?"

She got up and finally left the auditorium, cautiously making her way back to Stiles and the rest.

"And you sure it was Derek Hale?", Mr. Stillinski asked the teens as Scott, Stiles and Sam finally walked out of the school with him.

"Yes.", Scott answered. Sam glared at him, unbeknownst to the sheriff.

"I saw him too.", Stiles said.

"What about the janitor?", Scott asked.

"We're still looking.", the sheriff replied. Sam's eyes widened. He wasn't in the auditorium??

"Did you check under the bleachers?", Sam asked.

"Yes, Sam, we looked.", he answered. "We pulled them out just like you asked and there's nothing."

"But he was there. I-"

Sam paused. She never wiped her hand. She had someone else's blood on her hand. She could easily be a suspect.

"I know, I believe you, I do.", Mr. Stilinski said.

Sam frowned which caught his attention as he sighed.

"Listen, we're gonna search this whole school. We're gonna find him. Ok? I promise."

"Sheriff!" A man called out.

"Stay.", Mr. Stillinski ordered. "All three of you." Sam turned to face Scott and Stiles.

"Well, we survived, I guess.", Sam says.

"When we were in the chemistry room, he walked right by us.", Scott said. "You don't think that it heard us? You don't think it knew exactly where we were?"

"Then how are we still alive?", Stiles asked.

"It wants me in its pack.", Scott said. "But I think, first. . . I have to get rid of my old pack."

"What do you mean?", Stiles asked. "What old pack?"

"Allison.", Scott answered.

"Derek.", Sam added.

"Jackson."

"Lydia."

"You two.", Scott says.

"The alpha doesn't want to kill us.", Stiles said in realization.

"He wants him to do it.", Sam spoke.

"And that's not even the worst part.", Scott said.

"How in holy hell is that not the worst part, Scott?", Stiles asked.

"Because when he made me shift. . . I wanted to do it.", Scott said. "I wanted to kill you. All of you." They stood in silence.

Scott was ashamed and his friends couldn't fault him for it. Hell, Sam was still trying to cope with almost losing her life three times now.

She sighed and looked where Stiles' jeep stood, gazing past the truck to see a figure in the tree line.

Her heart dropped only to see a familiar figure. She felt relieved, shocked and pissed all at the same time. He was alive this entire time?

She turned to see if Scott sensed him, in which her assumption was right. His face was contorted in fear.

"Well, Sam, I was going to let you drive the Camaro home and let you use it until your mom could finally get you a car of your own, but we couldn't find a key.", Mr. Stillinski said, coming back over to them.

Sam smiled. "I can always hotwire it?"

He raised an eyebrow. "You know how to hotwire cars?"

Sam paused, her lips pressing together to silence herself. Was that a crime?

He sighed and shook his head. "Just get it out of here. Derek's body isn't here so… free car? Just don't tell anybody."

She grinned and ran over to the car and luckily the back door was still open so she could climb through to get into the driver's seat and hotwire the car.

Sorry, Derek.

As she got it to start, she relaxed at the vibration of the car. She instantly felt safe. She looked back at the treeline to see if Derek was still there. He wasn't.

She frowned. Though, she was grateful that he trusted her enough.
