"Derek what are you doing?" Cassidy asks as Derek walks over to where a badly burned Peter lays.

"Wait!" Scott shouts, "you said the cure comes from the one who bit you. Derek If you do this, I'm dead. Her father, her family what am I supposed to do?"

"You've already decided, I can smell it on you" Peter says right before Derek violently slashes his throat causing Cassidy to have to look away in horror.

Derek then looks up, his eyes meeting Cassidy's, she gasps when she see's them change from ice blue to blood red.

"I'm the Alpha now..."

-

I play the events of the last couple of hours through my head over and over, replaying the moment Derek's eyes changed into the red of an Alpha. And now I'm standing there in front of hospital debating with myself whether I should go in there or not, after all it's my fault Lydia's in there maybe if I had been there I could've stopped Peter, maybe it would be me lying in that hospital bed instead of my best friend.

"Cassidy" Stiles calls rushing out of the hospital looking quite distressed, "she's gone, Lydia's gone," fear ripples through me, does he mean she's dead?

"What do you mean she's gone?" I ask him eyes wide with shock.

"I mean she's nowhere to be found, it's like she disappeared" Stiles tells me making crazy hand expressions, "Cassidy I heard her scream" Stiles then says solemnly, for moment i'm relieved, at least she's alive, then I start to worry, where is she?

"Oh this is not good" I exclaim, "call Scott, you said he could track people by there scent, right?" I ask, in which he nods in response, good he can track her scent

"Good idea he can track her by her scent, wait here" he says like he was reading my mind, he grabs his phone out and runs back into the hospital leaving me standing there confused as ever.

A few minutes Later Stiles comes running back out of the hospital a gown clenched in his hand, "Scott will be able to use this to catch her scent" Stiles explains when he see's the confused expression on my face.

"Right" I say as Stiles jeep pulls up in front of us, "you let Scott drive your jeep" I say surprised seeing as though Stiles loves his jeep more than dear life, then again this is Lydia Martin we're talking about.

"This is the one she was just wearing?" Scott asks as Stiles passes him the hospital gown, "don't worry i'll find her, I won't let anything happen to her, not again" Scott says after noticing the fear in both mine and Stiles features, for some reason those words don't comfort me, for all we know she's dead, somewhere in the woods in a shallow grave just like Derek's sister Laura was.

"Just shove the thing in your face so we can find her" Stiles says getting into the jeep, "Woah" he shouts and I nearly scream as Alison appears next to me in the backseat.

"What are you doing, someone could see us" Scott says paranoid as he looks back at his 'forbidden' girlfriend and back at me, I snicker he really thought Alison wouldn't tell me about her secret love affair with him.

"I don't care, she's my best friend Scott, we have to find her before they do" Alison tells him getting comfy in the backseat of Stiles' Jeep.

"I can find her before the cops do" Scott replies subtly trying to convince Alison to leave this to him, Stiles and me, does he not know his girlfriend at all.

"What about before my father does" Alison snaps, causing Scott, Stiles and I to go completely silent, shocked expressions on all our faces, oh god now Lydia's really dead.

"He knows?" Both Stiles and I exclaim both starting to freak out with the new found information.

"I just saw him and three other guys leave in two SUV's" Alison responds.

"Search party?" Scott asks even though he knows that there is a much more realistic reason to why Chris Argent and three of his buddies are looking for someone who may or may not be a Werewolf, Crap!

"More like hunting party" Alison says, worry for her best friend finally showing on her face.

"They wouldn't really kill her would they?" I ask as Stiles quickly reverses out of the parking space, "I mean your dad didn't kill Scott so why would he kill Lydia? Who might not even be a werewolf."

"I don't know Cassidy, they won't tell me anything, all they say is, 'We'll talk after Kate's funeral, when the others get here'" Alison tells her, the other's sound even worse.

"What others?" Scott asks poking his head out the window to start sniffing, "that way" Scott says pointing in the direction he's getting Lydia's scent the strongest.

"They won't tell me that either" Alison tells them crosses her arms across her chest in frustration and annoyance, I soon join in, god her family is all kinds of messed up.

"Okay your family has serious communication problems to work on" Stiles says not a lick of humour in his voice, "Scott are we going the right way?"

"Take the next right" Scott calls back head still out the window as he turns his head in very which way making sure he's taking us in the right direction.

-

"She came here, you sure?" Stiles asks Scott as they walk up to the ruined house, chills pass through me as I remember the last time I was here.

-

"Scott you're eyes" Derek shouts, just as an arrow hits Derek in the leg.

"Derek" Cassidy yells running over to him to make sure he's okay.

"Cassidy no! Get down!" He shouts at her just as another whips past her gazing her arm.

-

"Yeah, this is where her scent leads" Scott tells him both looking very confused and a little surprised, not as surprised as me of course.

"All right but has Lydia ever even been here?" Stiles asks sceptical that this is the right location, "cause what reason could Lydia Martin possibly have to come here." I'm inclined to agree with him I never even wanted to come here, why would Lydia?

"Well she's never been here with me, what about you Cassidy? Have you ever been here with her before?" Alison asks turning around to face me.

"Not that I can remember" I reply, "maybe she came here looking for Derek" I then add, remembering Scott saying something about a newly turned beta being drawn to an alpha.

"Yeah like on instinct" Alison says agreeing with me.

"You mean looking for an Alpha?" Scott asks going along with it while Stiles stands there looking around in search for a certain strawberry blonde.

"Wolves need a pack right?" Alison then asks him.

"Not all of them" Scott replies, "I don't need a pack" he then tells her walking around still trying to catch Lydia's scent.

"Wouldn't she have still been drawn to Derek, like you were with Peter" I say looking around nervously wondering if Derek is out there somewhere watching us.

"Yeah I guess, we're stronger in Packs" Scott tells me kicking the dirt under his feet.

"Like strength in numbers" Alison asks looking at her boyfriend curiously.

"No like literally, we're stronger, faster, better in every way" Scott tells her, also drawing in my attention, interesting.

"Will that make Derek stronger too?" I ask now fully invested in the conversation, I then look back up at the house remembering the look in Derek's eyes when he became the alpha, not a speck of remorse in his features, just pure power.

"A lot stronger" Scott says emphasising on A lot, "he'll be able to draw in power from his pack and use it himself, which makes him the strongest person in Beacon Hills." Except he's not really a person.

"Whoa, hey look at this, I think it's a trip wire" Stiles exclaims overjoyed, way too over excited as he pulls the wire back, I go to stop him but it's too late.

"Stiles" Scott shouts while being wretched into the air by a rope wrapping around his leg, causing me to burst out laughing, the first time i've really laughed in the pass couple of weeks.

"Yeah Buddy" Stiles says turning around only to see his best friend hanging from a tree, "oh" Stiles replies while Alison tries to contain her own laughter.

"Next time you see a trip wire, try not to trip it" Scott says causing me to laugh even harder because Stiles is like a little kid, he can't resist shiny things like trip wires.

"Yeah Noted" Stiles mutters running a hand through his not existent hair, "i'll try my best" he then says sarcastically.

"Crap, run someones coming" Scott exclaims, "Hide go" he then says when none of us start to move from our places, all three of us then scatter into the woods just as Chris and his three goons appear.

"What are you doing out here Scott?" Chris asks in a friendly tone and a fake smile plastered across his face, causing me scowl.

"Looking for my friend" Scott tells him trying to act as casual as he can even though he's still hanging from the tree.

"Ah, that's right Lydia's in your group now, isn't she? Part of the clique? Is that the word you use? Or is there another way to put it? Part of your pack?" Chris says causing my heart to beat faster when he says Lydia's name, she's dead.

"Cliques sounds about right" Scott bites out obviously trying not to lose control on him knowing it wouldn't end well for anyone, especially him.

"Scott, do you know what a hemicorporectomy is?" Chris then asks as Scott sways in the wind the rope still intact around his leg.

"I have a feeling I don't want to" Scott replies and I have to agree with him, because whatever it is it does not sound good.

"It's a medical term for amputating somebody at the waist. Cutting them in half. Takes a tremendous amount of strength to cut through tissue and bone like that. Let's hope a demonstration never becomes necessary" Chris tells him putting his hand in the air just above Scott waist to show where he'd cut if it did ever became necessary, I shiver at the thought of getting cut in half, how medieval can you get?

"You okay?" Alison asks as we run back over to him after Chris and his hunting friends leave.

"Yeah just another life threatening conversation with your father" Scott sarcastically replies as he tries to get himself down.

"Help me with this" Alison says signalling Stiles and I over to help her get Scott down from the tree.

"Thanks but I think I got it" Scott says whipping his claws out and cutting the rope then landing gracefully on the ground, impressing all three of us.

"Whoa!"

-

I walk into my room exhausted having stayed with Lydia almost all night comforting her about her recent exhibition in the woods, good thing is that she's not a werewolf therefore keeping her safe from the Argents, bad thing is that if she's not a werewolf than what is she?

"Cassidy" I look up just noticing Derek standing there, I jump back in surprise and fear almost falling to the floor.

"What do you want?" I ask fear replaced with anger as I realise that he once again broke into my house.

"I need your help..."
