A/N: Before you read! This chapter is ridiculously long. This was one of my favorite episodes of the series. Couldn't help myself. ALSO, ALL THAT IS IN ITALICS IS FLASHBACKS.

"Faster!" I urged Stiles as he drove his precious Jeep down a winding road that lead to his own home. Even thought he was pushing double the speed limit, it wasn't enough for me.

"Hayley, what does it look like I'm doing?" He shot back.

"Matt could be in Canada by now, Stiles. He knows we know." I huffed, running a hand through my hair. I still couldn't grasp the concept of Matt being the Kanima master. I turned back to Scott, who sat in the back seat. "What are we going to do?"

Scott reluctantly shook his head, "I don't know."

Within twenty minutes the three of us and Sheriff Stilinski hovered over Stiles' desk, staring down at last years yearbook. While some names had been crossed out, Matt's photo was circled in red marker

"So this kid is the real killer?" Sheriff Stilinski rose a brow as he glared down the picture.

"Yeah." Stiles sighed. Scott and I nodded in unison.

"No." Sheriff immediately knocked the idea down.

"Dad, yes!"

"No."

"Dad, yes! Everybody knows the police look for ways to connect victims in a murder, okay? So all you have to do is, like, look through the transcripts and figure out which class they all had in common!" Stiles explained.

"Yeah, except for the fact that the rave promoter, Kara, wasn't in Harris' class."

"Yeah, alright, okay. Then I guess they dropped the charges against him?" Stiles asked.

"No, you know what? They're not dropping the charges. But that doesn't prove anything!" Stilinski defended. Stiles stammered his words in frustration. "Do you two believe this?" The father son duo looked over to us.

"It's really hard to explain how we know this, but you just have to trust us. We know it's Matt." Scott nodded. The Sheriff looked to me as Stiles threw jumbled words at him.

"He's telling the truth." I agreed. At this point, telling the Sheriff about how exactly we knew would have been more convincing than the way we were doing it. But we couldn't exactly say 'hey, Sheriff, we saw Matt with the giant supernatural lizard that's doing all the killings, he's the one'.

"He took Harris' car, okay? Look, he knew that if a cop found tire tracks at one of the murders, and if enough of the victims were in Harris' class, that they'd arrest him!" Stiles exclaimed.

"Alright fine." Sheriff caved with a groan. "I'll allow the remote possibility—only on one condition! I need a motive. I mean, why would this kid want most of the 2006 swim team its coach dead?"

"Isn't it obvious?" Stiles cried as Scott and I grew silent. There was a pause as Sheriff shook his head. "Our swim team sucks! They haven't one in like…six years." Stiles trailed off. I gritted my teeth as Stiles' lame and half assed excuse lost his father.

"They really do." I reluctantly agreed, pursing my lips. "Just…really bad…" I grimaced. "Okay, we don't have a motive yet but you have to believe us."

"What do you want me to do?"

"We need to look at the evidence." Scott spoke up when Stiles realized we had successfully managed to convince his dad.

"Yeah, that would be in the station, where I no longer work."

"Trust me, they'll let you in." Stiles assured.

"Trust you?" Sheriff fumbled over his words in disbelief that his son would ask such a thing.

"Trust—trust Scott?" Stiles corrected. Insulted, I looked to Stiles with my brows furrowed and lips pouted. Was I suddenly not trustworthy?

"Scott I trust." The Sheriff admitted.

By almost a quarter to two, I found myself walking inside the police station. Scott and Stiles stood by my side while the Sheriff stood ahead of us at the front desk, attempting to persuade the women to let him through to the back. My brother and Stiles whispered back and forth about deciding on looking at the hospital footage first since that was the only murder not committed by Jackson.

"There's cameras in almost every square inch of the hospital, Matt has to be on there somewhere." I mentioned quietly.

"Kids." The Sheriff called, motioning us to follow him into the back. Relief settled over me knowing that we were past the hard part of getting through. Now, it was time to get evidence on Matt and put him away. It took a few minutes to pull up the hospital camera's footage from the second floor where the pregnant girl was killed. We rolled through it, growing anxious when we couldn't spy Matt anywhere.

"There was a six car pile up that night, the hospital was jammed." Sheriff sighed.

"Alright just keep going. Look, he had to have passed one of the cameras on that floor to get to Jessica, okay? He's got to be on the footage somewhere."

"Oh hold on! Stop!" Scott cried. "Did you see that? Scroll back." The footage quickly reversed. Among several patients and nurses, a man clad in a leather jacket barged down the halls, walking with purpose.

"That's him! That's Matt!" Stiles shouted. Sheriff paused the footage.

"All I see is the back of a head."

"Matt's head, yeah! I sit behind him in History. He's got a very distinct cranium. It's weird."

"Are you crazy?" The Sheriff blatantly asked his on.

"All right! Fine! Then look at his jacket, huh? How many people do you know who wear black leather jackets?" Stiles asked. The Sheriff rose a brow, looking from Stiles and over to me. Everyone's eyes fell on me, specifically to my black leather jacket. I looked to Stiles, silently assuring him that he was an idiot.

"Millions, literally." I blandly stated.

"Who's team are you on here?" Stiles groaned.

"Okay enough! Can we scroll forward? There's got to be a shot of him coming at one of the cameras." The footage switched cameras and quickly continued to scroll.

"See, see! There he is again!" Stiles pointed out, causing Sheriff to pause the footage.

"You mean there's the back of his head again." Sheriff corrected.

"But he's talking to someone!"

"Yeah, he's talking to my mom." I realized, my teeth gritting. The thought of the murdering scum bag going anywhere near my mother burned a fire inside me.

Shortly after finding mom on the footage, Scott and I had the guts to call her. She had just gotten home from work, and was not in the mood for any of our questions. We put the phone on speaker, waiting for her to confirm the leather jacket wearing figure was Matt.

"Do you two know how many people I deal with in a day?" She scoffed.

"Yes, yes! But he's 16, dark hair, looks like your normal run-of-the-mill teenager…" I trailed off, trying to think of anything to jog her memory.

"He looks evil!" Stiles leaned into the phone and inserted. I shoved him away. Now wasn't the time.

"Hayley, I already talked to the police about this."

"Okay, mom, I'm going to take a picture and send it to you." Scott intervened. He quickly grabbed the phone and snapped a picture of Matt's yearbook photo. "Did you get it?" He asked after he heard the swooshing of the sending noise.

"Yeah." She skeptically answered.

"Do you recognize him? Do you remember him?"

"Yeah, I did. I mean, I remember I stopped him because he was tracking mud in the hall." Mom recalled. The Sheriff glared at all of us, finally realizing this was true. The mud must have been from the husband that was killed before Jessica. He was found in the woods near a swamp, Matt had to have been there controlling Jackson.

"Kids, what's going on?"

"It's nothing mom. I'll explain later. We got to go." Without biding a goodbye, Scott hung up the phone. Sheriff began working fast, grabbing a manila folder and searching through the papers.

"We found shoe prints alongside the tire tracks at the trailer site." Sheriff informed.

"If they math that puts Matt at the sight of three murders! The trailer, the hospital, and the rave!" Stiles realized.

"Actually, four. A credit card receipt for an oil change was signed by Matt at the garage where the mechanic was killed."

"When?" Scott and I wondered.

"A couple hours before you got there." Sheriff looked to his son.

"Alright dad if one's an incident and two's a coincidence, and three's a pattern, what's four?"

"Four's enough for a warrant. Call your mom back, see how quick she can get here." Sheriff urged. Scott grabbed the phone first and started dialing. "If I can get an official ID, I can get a search warrant. Hayley, go to the front desk with Stiles and tell them to let your mom in when she gets here."

"On it." Stiles informed. Before leaving the room with him, I stripped of my jacket and threw it on a chair.

"I can't believe we're going to get him." I realized.

"I kn…" Stiles' words were cut off once we reached the front lobby. The night guard manning the desk had disappeared. My first initial thought was she had taken a coffee break, but the station suddenly became eerily quiet.

"Hello?" Stiles called. My throat tightened. Something didn't feel right. I took a step forward only to freeze immediately in my spot. I looked down to the floor, the guard sprawled out in front of me. Her shirt was cut up and tainted with blood, the khaki fabric quickly dying itself a deep red. Her chest had been mutilated with rips and tears, ones that didn't look like they came from a knife. Her eyes were left wide open, her body lifeless. A wave of nausea rolled itself into my tightening throat as a shaky breath managed to escape through my parted lips. Nothing human did this. The Kanima was here. Stiles and I both whipped around quick in hopes to warn his father and Scott of the impending danger. Instead, we were greeted by the metal barrel of a gun. Matt glared at us with a crazed look in his watery eyes. His lips picked up into a smirk as he jabbed the gun at us and silently ordered us to move.

The barrel of a gun was aimed right at me. My eyes grew large, watching my father fall to the ground. Red liquid spilled out of his body, staining the once pristine beige carpet. There was screaming and yelling, dad was shouting at me. I looked past the barrel and to the man holding the weapon. He cocked his head as he stared at me. His eyes were red and watery, yet his face was almost relieved. His finger hovered over the trigger of the gun. James pulled back the top of the gun, the weapon clicking.

The sound of clicking—a gun cocking—rang in my ears. I walked through the stations hallways, Stiles at my side and a gun aimed at my back. Matt was more than happy to release the trigger.

"Sherriff?" I heard Scott question when he realized something was wrong. Stiles and I walked through the door, Matt pushing us forward as he shoved the barrel into our backs. I walked forward, taking a stand beside my brother. Stiles did just the same. Scott's jaw dropped.

"Matt? It's Matt right? Matt, whatever is going on I guarantee there is a solution that doesn't involve a gun." Sherriff calmly spoke.

"You know, it's funny you say that, because, I don't think you're aware of how right you are."

"I know you don't want to hurt people."

"Actually, I wanna hurt a lot of people. You four weren't on my list but I could be persuaded. And one way is to try dialing somebody on your cell phone like McCall is doing." I froze, looking to my side at Scott. His hand was halfway in the front pocket of his jeans as the movement of his fingers attempted to go unseen. Quickly, Scott pulled his hand out of the pocket. He swallowed hard. "That—that could definitely get someone hurt." Matt paused. I looked over to my leather jacket strewn on one of the chairs. There was no way I could even attempt to get to it without Matt realizing now. "Everyone. Phones! Now!" He barked. Looking up to Matt, I put my hands up at my side to show him I wasn't trying to do anything to get hurt. I slowly leaned to the side and reached into my jacket pocket, grabbing my phone and showing it to him. As I placed it on the table, my home screen lit up with a message from Derek: Where are you?

I wasn't sure of how much time had gone by the time Matt had led us to the holding cells. It had felt like an eternity though. Stiles was finishing hand cuffing his dad to the wall, Matt watching his every move as he aimed his gun at the Sheriff.

"Tighter." Matt ordered, wondering if Stiles thought he was an idiot.

"How are we going to get out of this?" I whispered to Scott.

"I don't know." He honestly answered.

"Do what he says Stiles." The Sheriff agreed to his son.

"Did you tell Derek we were here?" I quietly asked. Scott shook his head, his eyes glued on Matt.

"I left a message saying it was Matt, nothing about where we were going." Scott whispered back.

"What—"

"Hey! Did I say anything about talking being allowed?" Matt snapped, turning around on his heel and pointing the gun at us. Scott and I both closed our lips tightly together. "Move, now." He urged. With a gun to our backs, Matt followed us close behind as we traveled through the hallways and back towards the Sheriff's office. Passing an adjacent hallway, Scott stopped short in his place, his face contorting with horror. I looked into the adjoining hallway, my heart pounding twice as hard as before. Knots formed in my stomach and throat, my hands beginning to shake while a familiar metallic smell wafted up into my nose.

There was blood. So much blood.

Not that blood wasn't anything I haven't seen before. Carnage and despair seemed like a weekly occurrence in Beacon Hills nowadays.

There was blood smeared all over the walls, hand prints and splatters were everywhere. I blinked, hoping the scene in front of me was a flashback of my parent's slaughter. It looked just as similar. Blood. Blood everywhere.

My eyes failed to rid of the scene in front of me.

The bloody bodies of three male officers were strewn and slumped on the floor. Their chests were ripped open and blood was pooling everywhere. There was an officer in the back, his chest slowly rising and falling. His eyes were open and they pleaded for help. I swallowed hard.

"Are you going to kill everyone in here?" Scott barked. Matt scoffed, finding Scott's troubled question amusing.

"No, that's what Jackson's for. I just think about killing them! And he does it." Matt smiled as he shoved us forward.

Back in the Sheriff's office, Stiles was hovering over the computer, his fingers typing away at the keyboard as he deleted crucial files involving the murders and all evidence of Matt being involved whatsoever. Scott was shredding all the physical evidence Stiles' dad had in a file—blood samples, finger prints, crime scene photos…everything was being destroyed as if it had never existed in the first place. I, on the other hand, was sitting on the couch with Matt at my side. He sat relaxed as he pointed a gun at my side. I stayed perfectly still, afraid that even moving an inch would set Matt off.

"Deleted. And we're done. Alright, so Matt, the people you brutally murdered deserved it because they killed you first—whatever that means—I think we're good here, right? So I'll just get my dad, and, we'll go. You know, you continue the whole vengeance thing. Enjoy the Kanima." Stiles spat with dry sarcasm. A pair of headlights shone through the office windows before Matt could even react. They illuminated on the four of us, my heart racing as I wondered who was about to step into the death trap.

"Sounds like your mom's here, McCall's." Matt realized, his face still as a stone as realization came over me that Scott had told mom to come to the station. My heart skipped two beats and thudded loudly against my chest.

"No, no, no, no, no." I found myself babbling. I could feel my pulse pound in my ears as I could taste bile in my throat. "Matt don't do this. You can't do this. Leave her out of it, please." I couldn't let mom die. I couldn't.

"When she comes in the door I'll just tell her to leave! I'll tell her we didn't find anything! Please Matt." Scott begged. A sickening smile lifted Matt's lips as he heard the screeching of the front door open.

"Matt, please, no." I begged, my voice shaking. Scott and I looked to each other in utter terror.

"If you don't move, now," Matt laughed subtly, "I'm going to kill Hayley first. And then Stiles. And then your mom." Scott willingly nodded and took a step forward. Matt jammed the gun's barrel into my side, seething at me to get up. Scott, Stiles, and I slowly walked out of the office and into the adjoining room where the main door was shut. I could already imagine mom walking out of the lobby and down the hallway down to the door where her fate would be sealed. I stared at it, millions of thoughts racing through my head. If I yelled and rebelled against Matt's orders, there was a chance mom would be able to run and get out. But, there was also the hundred perfect guarantee I wouldn't. I'd have a bullet through me in seconds.

"Open it." Matt ordered.

"Please." I whispered.

"Open. The. Door." He snarled. I looked to Scott, who gulped and nodded his head. I dug my nails into the palm of my hand as I braced myself for what was about to happen. Scott reached forward and reluctantly turned the door knob and pushed it open. Instead of mom standing on the other side, we were greeted by Derek looking at us with his usual scowl. Immediately, I felt a breath of relief exit my chest.

"Oh thank God." Scott breathed out the words we all were thinking. Derek blinked at us, not saying a word. The relief that had washed over me quickly began to fade away. It managed to completely abandon me as Derek tumbled to the ground—paralyzed. Our eyes darted from Derek to the doorway, where Jackson stood. He was still human, yet his skin was scaly and his eyes looked to those that belonged to a snake. Like a robot, Jackson walked into the room and stood in the doorway of the Sherriff's office as he waited for Matt's ongoing commands. I looked to Derek in fear, praying that he had a plan for us to get out of this. Matt squatted down and grinned at him.

"This is the one controlling him? This kid?" Derek sneered.

"Well, Derek, not everyone's lucky enough to be a big, bad werewolf." Scott, Stiles, and I looked to each other. Part of me was surprised Matt knew, the other wasn't. If he knew about, and was controlling, the Kanima there was no doubt he knew about everything else. Matt straightened himself up. "Oh yeah! Yeah! That's—that's right! I've learned a few things lately! Werewolves, hunters, Kanimas. It's like a freakin' Halloween party every full moon. Except for you two. What do you turn into?"

"Abominable snowman. But, uh, it's more of like a wintertime thing? Seasonal." Stiles retorted. I kept my mouth quiet, wishing Stiles would do the same. Matt quickly nudged his head to the side and beside me, Jackson lunged forward and swiped his claws at Stiles.

"Hey!" Scott and I yelled, turning around to face the half lizard. Jackson quickly put his hand out and wave his clawed finger, indicating for us not to move. I took a step back and away from him.

"Bi—itch." Stiles stuttered as he toppled down onto the ground, on top of Derek no less.

"Get him off of me" Derek grunted.

"Oh, I don't know Derek! I think you two make a pretty good pair!" Matt smirked, leaning back down. He turned his head over to me. "Isn't that right?" He cocked his head. My wide eyes turned a fraction of a bit bigger. How could he possibly know about that? Matt turned back to look at Derek and Stiles sandwiched together. "It must kind of suck though, to have all that power taken away from you with just a little cut to the back of the neck. I bet you're not used to feeling this helpless."

"Still got some teeth. Why don't you get down here a little closer, huh? We'll see how helpless I am."

"Yeah, bitch." Stiles agreed, his voice muttered by his mouth being pressed into Derek's shirt. A pair of tires squealed as they peeled into the parking lot, and for the second time tonight, headlights shone through the window. My heart dropped into my stomach once more.

"Is that her?" Matt smiled, his voice filled with his own sense of sociopathic humor.

"Don't do this." I gritted through my teeth together.

"Do what I say and I wont hurt her. I wont even let Jackson near her!" He promised.

"Don't trust him!" Stiles cried. Sick of Stiles' games, Matt yanked him by the back of his shirt off Derek and onto the floor. Immediately, he pressed his foot down onto Stiles' throat.

"This work better for ya?" Matt growled, his body shaking. Stiles gagged for air as his face began to turn pale.

"Hey! Just stop! Stop!" Scott ordered. I looked down in fear as my best friend choked on the little air he had remaining in his lungs.

"Then do what I tell you to!"

"Okay! We'll do it! Okay! Just stop!" I yelled. Instead of releasing his foot off Stiles' throat, Matt pressed down harder. Stiles attempted to gasp for air. "I said we'd do it Matt, stop!" I continued to yell. What seemed like an eternity later, his foot was off Stiles and my best friend was left wheezing for air.

"You," he looked to Jackson, "take them in there. And you two…with me."

The walk to the lobby felt like I was walking to my funeral. My heart pounded vehemently against my rib cage as I watched mom push through the double doors.

"Mom." Scott attempted to call as calmly as possible. Mom sighed with relief as she looked around the station.

"You scared me." She quietly chuckled. "Where is every…" Mom's voice faded off as she spotted Scott and I in the hallway. Matt stood behind us, his gun pointed straight out.

"Mom, just do what he says. He promised he wouldn't hurt you." I assured, my voice flat. Mom took a step back, fear evident in her eyes. Her lips parted as she let out a shaky breath. My brother and I turned around to face the serial killer.

"He's right." Matt agreed happily. Matt's finger pulled on the trigger and an explosion rang in my ear. Scott fell to the ground, his green shirt staining with dark blood around his abdomen. I gasped and mom shrieked at the top of her lungs.

"Scott!" The Sheriff screamed from the other side of the station. "Stiles! Hayley! What happened!"

"What are you doing? You promised!" I shouted, my face turning red with anger and tears brimmed my eyes.

"All I said was I wasn't going to hurt her." Matt calmly shrugged, taking a step towards me.

"Baby! Baby!" Mom rushed forward.

"Back! Back!" Matt yelled, pushing himself forward as he wielded the gun from mom to myself.

"Mom, mom, stop mom!" Scott urged, grunting in pain as he pressed down on his wound.

"I said get back." Matt hissed to mom.

"Don't do it Matt." I spat.

"Scott…" Mom's voice cracked.

"Mom, do it. Please mom." Mom hesitated.

"Mom, do it. Now." I begged, squaring my jaw.

"Get up McCall." Matt ordered Scott.

"Matt, Matt listen to me—" The Sheriff began screaming.

"Shut—shut—shut up!" Everybody shut the hell up!" He screamed. "Now get up or I shoot her next!" Matt pointed a gun to my head. Without hesitation, Scott stood up. I looked at Matt with rage pumping through my veins. I swallowed a rock hard lump in my throat, waiting for Matt to pull the trigger. Surprisingly, he never did.

Matt forced us back to the holding cells. Mom was continuously crying, her eyes caked underneath with mascara. She continued to sob desperate "no's" in hopes that Matt would listen. Scott leaned against the wall beside the Sheriff as Matt locked mom up in one of the cells. My heart broke as she watched us in panic, believing her son was going to die from his wound and not knowing what was about to happen to her daughter.

"Please, he needs to see a doctor." Mom sobbed.

"You think so?" Matt asked, amusingly.

"Hey! Hey! Hey! You listen to me!" The Sheriff, still handcuffed to the wall, stood up and jabbed his finger in the air towards Matt.

"It's all right! I'm okay!" Scott promised.

"No, honey, you're not okay."

"Mom, he'll be fine. I promise." I tried to assure.

"It doesn't hurt mom."

"Because that's the adrenaline, okay? Please, let me—let me just take a look at him, okay? I can help stop the bleeding." Matt began laughing, looking over to Scott and I.

"They have no idea, do they?" He cackled.

"Matt this isn't the place! Not now." My voice rose. Behind him, mom kept pleading for Matt to let her look at her son.

"Shut—shut—shut up—shut up!" Matt bellowed. "Lady, if you keep talking I'm going to put the next bullet through both their brains." Terrified for our lives, mom quietly agreed.

"Back to the front. Both of you. Now!"

With Matt's gun still aimed at my back, I walked through the doorway of the Sheriff's office. Derek and Stiles were paralyzed on the ground, their eyes darting back and forth between Scott, me, and Matt.

"The evidence is gone; why don't you just go?"

"You—you think the evidence mattered that much, huh? No, no. I, I want the book!" Matt stuttered.

"What—what book?" Scott asked.

"The bestiary! Not just a few pages, I want the entire thing!"

"We don't have it. It's Gerard's, why don't you go bother him for it?" I finally spoke up.

"What do you want it for, anyways?"

"I need answers." Matt quietly admitted to Scott.

"Answers to what!" Scott cried.

"To this." Matt reached down and pulled the hem of his shirt up, revealing patches of scales and green on his side. Beside me, Scott audibly gasped. My brows bunched together. In a daze of confusion, I horridly began to realize Matt was slowly turning into a Kanima.

"Watch them." Matt spat at Jackson. He stormed over to the table where we placed all our phones in a pile. He grabbed Scott's phone and tried typing in a few different passcodes. "Open it! Now McCall!" Matt roared. Scott quickly took the phone from Matt's grasps and typed in his phones password. Seven digits. Allison no less.

"What do you want me to do?" My brother wondered. Matt straightened his arm out and aimed his gun at me.

"Text Allison you want the Bestiary." The weapon clicked, indicating it was ready to fire. My body froze, a shiver making its way down my back. "You tell her to bring it here. Nothing more. Nothing less."

"Matt, she's not going to give it to me! Gerard's the one who has it!"

"Do it now, McCall!" Matt screamed, his breathing heavy. His voice lowered. "Do it or you can say goodbye to your sister." Matt paused, a grin lifting up his lips. "Or should I say your cousin?" He cocked his head. My body became rigid as I lifted my eyes to meet Matt's gaze. My lips parted, wanting to speak but too surprised to get words out of my mouth. Scott's thick brows knitted together as he was overcome with confusion. "Yeah, that's right. I know about that. I know about everything."

"But—"

"Send the text, McCall!" Matt yelled once again. Scott's fingers hovered over the phones screen as he was unsure of what to do. Scott's split second hesitation was enough to set Matt off. His finger pulled back on the trigger.

Bang.

Bang.
