I couldn't sleep that night, no matter how much I wanted to. My body was weak, my brain tired, yet it was still whirring around, thinking about the Kanima, Derek, but most importantly Isaac and the kiss. Why had he done it? Did it mean anything to him? And why had he left straight after? Did he have feelings for me?

I got up the next morning with tired eyes and a bad mood. Even more so because Isaac and I were still on opposite sides. I was glad he was on the run though, because I was not prepared to see him at school today, or at all.

I still didn't know what to say to him. I liked him a lot, but he was on the opposite team. I couldn't go frolicking with the enemy, could I? And he was the enemy, as painful as it was to admit it. Derek wanted to kill the Kanima, which meant Isaac would also help kill it, and I couldn't stand for that.

I sighed as I got into the car with Allison, the ride silent as my mind went over the kiss last night again. It had been something. The feeling of his lips on mine, the possessive way he had grabbed my hips and pulled me closer, like any space between us was an insult. The way he had stared at me after it, smug smile and all.

"You okay?" Allison asked when she parked the car. "You seem a bit out of it."

I sighed. "Just tired from last night."

Allison gave me an understanding smile and we got out of the car, walking towards the school together. We got our books, and had just reached class, entering the room, when I stopped in my tracks. Rooted to the floor, I stared at Isaac's back, my brain short circuiting once again. He was wearing the leather jacket again, and I couldn't think.

I couldn't think, couldn't breathe, couldn't blink as Isaac turned around, as if sensing my gaze, and our eyes met. It was like fireworks going off, the way he stared at me, with the tips of his lips tugging into a smirk, the way his eyes shone with excitement.

I was gonna throw up.

I grabbed Allison's hand and dragged her out the room, desperate to get away from him. What was happening? How was he here? Wasn't he still a fugitive?

"What are you doing?" Allison asked, though didn't stop me as I took her further away from the classroom.

I glanced furtively behind me, but Isaac didn't seem to be following us. "Isaac is back."

Allison followed my gaze. "It's not that bad. I thought Isaac was your friend."

I took Allison into the girl's bathroom, checking all the stalls were empty before turning to Allison. I was frantic, eyes darting to the door like Isaac was going to enter the room at any moment, even though it was the girl's bathroom.

"Isaac kissed me."

Allison gaped at me, eyes wide in shock as she stared at me, flabbergast, just as Lydia entered the room. She observed the scene with interest.

"Who kissed you?" she asked, only managing to catch the last part of the sentence.

Allison turned around, startled. "Why are you here?"

Lydia rolled her eyes. "I saw my two friends skipping class to talk in the bathroom, so I followed. Obviously."

I nodded, feeling nervous as I fidgeted with my hands, and Lydia repeated her question, looking at me expectantly.

I looked down at my feet as I mumbled, "Isaac Lahey."

Surprise crossed Lydia's face. "He's at school today."

I groaned, covering my face with my hands. "Exactly!"

"Do you like him?" Lydia questioned.

I shrugged, not sure what to say, and both girls glared at me. Apparently shrugging was not a good enough answer for them.

I sighed. "Maybe a little."

Lydia clapped her hands happily, a grin on her face, before she focused on me, her expression turning serious. "So what's the problem then? Was he a bad kisser?"

I opened my mouth to answer but faltered at the last second, unsure how to word my situation to Lydia who had no idea about the supernatural world. "Nothing like that. He- um. We're sort of in a fight, or at least our friends are, and he left right after kissing me so I have no idea what it meant or..."

I trailed off, feeling I'd given enough information about my current predicament. Lydia nodded, tapping her chin as she thought.

"Well," she drawled." You can either confront up," I grimaced, "or you can ignore him."

"I like that one better," I said instantly.

Lydia rolled her eyes at me but didn't try to change my mind, thankfully, because I was not about to confront Isaac about the kiss. I would much rather ignore him and pretend like it never happened, at least until I figured out how to approach the situation.

"You've got to go to class then," Lydia stated. "No matter if he's in it or not. Otherwise you won't be ignoring him, you'll be avoiding him, and that would only make him know you were freaking out about this."

I nodded my head, though in reality I wanted to do anything but. Maybe the Kanima was up for a second round, because currently I'd prefer that over having to sit in class with Isaac for fifty minutes.

Lydia spent the remaining time of this class, because I couldn't go back into the class otherwise it would be obvious I'd been freaking out, lecturing me on dating. She told me what to wear on what occasions, how to act depending on how he reacted to my ignoring him, and how to kiss properly.

My brain was overloaded with information, half of it stuff I was definitely not going to use, but nonetheless I thanked her as the bell rang and we exited the bathroom. I was instantly scanning the halls, feeling my heart sink and soar at the same time when I spotted Isaac.

He must have scented me, because his head instantly shot up and his gaze found mine as soon as I'd entered the hallway. I averted my gaze, feeling panicked, and turned around, walking the opposite way from him.

Lydia sighed as she and Allison fell in step beside me. "You're horrible at this," she muttered to me.

I grumbled as Allison laughed, but said nothing as we walked to our lockers to get our stuff for next class that I was desperately hoping I didn't have Isaac in. Unfortunately, fate was not on my side as I entered the classroom and found Isaac sitting near the back, his head lolling back as he waited for class to start.

When I walked into the class he stood up though, as if intending to talk to me, and I immediately sat down in the front, keeping my head down as Allison sat down next to me. My heart was hammering in my chest, and I could only assume that he could hear it, that he was listening to it give me away.

I swallowed thickly and spent the rest of the class staring straight ahead, all the while feeling Isaac stare holes through the back of my head. I didn't look back though, was determined not to as I half heartedly completed the work, my mind on other things.

The bell rang and I sighed, relieved, as I packed up my stuff. I reached the doorway to leave when none other than Isaac Lahey blocked it, staring down at me.

"Y/n..." he started.

I froze. I was going to die. Isaac Lahey would be the death of me. Just his voice was enough to make my knees weak, and I was brought back to last night, the way his lips had pressed against mine.

Allison smiled sweetly at him, linking our arms. "While I'm sure Y/n would love to talk to you, she doesn't want to be late for class, so you'll have to save this conversation for later."

Isaac stared at me while I looked at my shoes, which had become remarkably fascinating, before sighing and moving aside, letting us through. I breathed a sigh of relief, silently thanking whatever being let me have Allison as a friend, before going to my locker, only to find Scott and Stiles already there waiting for us.

They had some news for us. Apparently Derek had done a test on Jackson to see if he was the Kanima, feeding him the Kanima's own paralysing venom. If he went paralysed, he wasn't the Kanima, but if he did, he was the scaled lizard creature. The test had failed on him miserably, so now they were setting their sights on Lydia, which meant if they found out she was the Kanima... they'd kill her.

We entered Chemistry class, still wrapped up in our conversation.

"Derek's not going to kill her without proof," I said.

"So he tests her like he did with Jackson, right?" Stiles asked. "But when and where?"

We all looked at the classroom and found Lydia sitting alone at a desk, lazily flipping through her text book. We then saw Erica and Isaac enter from the opposite end of the room, their gazes latching onto Lydia.

"I think here and now," Scott said.

We raced to the spare seat next to her, Scott getting it just in time as Stiles haphazardly pulled up a stool next to the desk. Isaac and Erica reluctantly sat on the desk behind them, and I took the free spot next to Allison, trying my best to avoid eye contact with Isaac.

Mr Harris walked into the room, the whole class silencing in fear of the big bad teacher. It would be comical, if I wasn't so nervous about the situation currently unfolding with Derek and Lydia.

"Einstein once said, "two things are infinite: the universe, and human stupidity; I'm not sure about the universe," Mr Harris said, looking at his class with distaste as he started walking around the classroom. "I myself, have encountered infinite stupidity," he chose this moment to clap Stiles on the shoulder.

I took the chance to look at Isaac, only to find his piercing blue eyes already staring right at me. My throat bobbed as I turned back around, feeling my heart racing.

"So, to combat the plague of ignorance in my class, you're going to combine efforts through a round of group experiments," Mr Harris continued. "Let's see if two heads are indeed better than one. Or in Mr Stilinski's case, less than one."

I scowled. Mr Harris reminded me a lot of Severus Snape from Harry Potter. I hated Severus Snape.

"Erica, you take the first station," Mr Harris said. "You can start with-"

Mr Harris stopped speaking as majority of the males in the class put their hands up, and even a few females as well. Erica smirked. I rolled my eyes.

"I didn't ask for volunteers," Mr Harris gritted out. "Put your hormonal little hands down. Start with Mr McCall."

Scott didn't look very pleased with the arrangement, and I couldn't really blame him. Erica on the other hand looked positively delighted, excited to be a menace to society and cause mischief.

"All right next two," Mr Harris mused, scanning the rows of students. "Y/n and... Isaac."

No. No, no, no. Not Isaac. Anyone but Isaac. I heard wrong, right? I must have heard wrong, yet as I looked to Allison with horror, she was staring at me with pity on her face, giving me a sympathetic smile.

"It'll be alright," Allison assured me. "You'll survive."

I gripped her arm tightly to stop her from leaving her seat. "No I won't. Don't you see Allison? I'll die. I'll pass away, never to be seen again because my soul will have already descended into Hell. I can't do this Allison. Stay, please. Don't let me die."

Allison just patted me in the back before standing up and walking to her partner's table. As soon as she left Isaac was there, sliding into her vacated seat as I bussies myself with getting the stuff for the science experiment ready.

Isaac sighed. "Did you really hate it that much?"

My head snapped up a I stared at him. "What?"

"Did you really hate the kiss that much?" he asked.

I frowned, my hands stilling. "Who said I hated the kiss?"

Isaac shrugged, pretending to think. "I don't know, maybe the fact that you've been avoiding and ignoring me all day."

I pouted. "I haven't avoided you. I only ignored you."

Isaac raised his eyebrows. "Proving my point right now."

I looked at my hands, curled around a test tube I had been about to pour into the flask. I sighed and placed it carefully on the table before facing Isaac. "I didn't hate it."

Isaac smiled, opening his mouth to say something but I pointed at him aggressively and he clamped his mouth shut, eyes fixed nervously on my finger. "But I do hate what you're doing now. You're supposed to be my friend, yet last time I checked trying to kill your friend's friend is against the bro code or whatever."

"So you see me as a friend?" Isaac asked.

I blinked. "What? No, that's not what I-"

"So you think of me as more than a friend?"

I glowered at him. "You are infuriating. I'm trying to tell you not to murder my friend, not that I like you."

Isaac smirked, leaning towards me. "So you do like me?"

I swallowed thickly, feeling my heartrate speed up as he got closer. Our faces were mere inches apart, and if I tilted my head up a bit and moved forwards, we'd be kissing.

I looked away, moving back a bit. "Not if you kill Lydia. In fact, if you kill her, I will hate you forever. As long as I live I will hate you if you even lay so much as a hand on her."

Isaac recoiled back slightly, hurt flashing across his face before it was replaced with blank indifference. I hated it, but there wasn't much I could do about it. What I'd said was true. I would never forgive him if he hurt Lydia, not when she hasn't done anything wrong. Not when she's my friend.

Before we could say anything else Mr Harris rang the bell, gathering out attention. "Switch!"

I got out of my seat before Isaac could say another word and sat at an empty table, seeing Scott had already taken the seat next to Lydia. Unfortunately for me, Erica happened to notice the empty seat next to me and slid into it with a cruel smirk.

I sighed, focusing on the science work as I tried to ignore the blonde girl beside me. She fake pouted, crossing her arms mockingly as she leaned closer to me.

"What's wrong? Don't want to be my friend anymore now that I'm better than you?" she asked derisively.

I snorted, pouring some of the mixture into the beaker. "I don't want to be your friend because your newfound 'power' has turned you into a narcissistic bitch."

Erica scoffed, her hand darted out to grab my wrist as her face contorted into one of rage. She let out a soft snarl, her claws coming out, digging into my skin. "Please, you're just jealous."

My eyes narrowed as I stared at her, lips twisting into a scowl. "You should remember who you're talking to," I spat.

As soon as I stared the words, whatever skin of Erica's was touching mine burned, a nasty, vicious burn, as if she'd just put her hand straight into a fire. Erica hissed, ripping her hand away from mine as she stared at the damage I'd done to her, angry welts decorating her usually flawless skin. I smirked, satisfied with myself.

Erica stopped talking long enough for my eyes to find Isaac, on their own accord. He looked really good in leather. I knew I'd thought it before, but the way it clung to his body, the way it only boosted his confidence, made my legs feel a little weak just staring at him.

I only spared him a second before I was back to working on the experiment, but that was all Erica needed to spot the glance. She gasped, leaning forward, her earlier wound forgotten. I gritted my teeth, wondering if there was a spell to cause permanent damage to a werewolf.

"What?" I snapped.

Erica laughed, amused. "I can smell Isaac's lust for you from all the way over here, but I didn't know the feeling was mutual. You hide your feelings well. Oh, how interesting is this? I know Derek would love to know the infamous witch as it for one of his pack members."

"Shut it," I hissed.

Erica gave me a simpering smile. "Is the little witch upset? I can't blame you though, because he certainly looks like something yummy, doesn't he? You know, us pack members have to share very close quarters, and who knows what could happen when we're so close together-"

I gave up focusing on the science project, turning around to glare at Erica, grabbing her wrist. I used the same spell as before, causing Erica to wince in pain as I gripped her wrist tightly.

"Keep talking and I'll burn you to smithereens right here, right now."

I let go of her wrist just as Mr Harris rang the bell, signalling for us to swap partners again. I shot Erica one last dirty look, one she returned as she rubbed her wrist that was already healing, and turned to find another desk to sit at.

I ended up sitting next to a guy I didn't know, only to find Isaac sitting next to Lydia. I felt sick to my stomach as I focused on the experiment, glancing up every now and then to see if Lydia was still alright.

I went to grab one of the flasks as the same time as the guy, both of us giving the other an awkward smile.

"Sorry," we both said at the same time.

The guy held out his hand. "I'm Matt."

I smiled, shaking his hand. "Y/n."

"So, how do you know Allison?"

I blinked, surprised at the question. I cut him a glance. "Um, sorry?"

He hurriedly explained. "I saw you guys sitting together earlier, and I've seen you guys hanging around before."

"Oh," I said, only a little bit weirded out. My gaze travelled back to Isaac as I answered his question. "We're cousins. Sort of. My guardian was her aunt."

I watched as Isaac's lips tugged into a smirk as he talked to Lydia, the way he stared at her with a predator's gaze. I clenched my hand into a fist.

"Do you, uh, do you know if Allison is dating anyone?"

I turned away from Isaac, surprised, as I faced Matt. "You like Allison?"

Matt ruffled his hair a bit, glancing at Allison from across the room. "Uh, yeah..."

I hid my wince, feeling bad. Matt seemed like a good guy, hoping that the girl he liked might give him a chance. Unbeknownst to him though, Allison was still dating her ex, meaning he didn't have half the chance he thought he did.

"Um, I'm not really sure," I lied. "She doesn't really talk about that stuff."

Matt nodded his head, his eyes straying to Allison again, making me feel even guiltier. He seemed to really like her, and though I had nothing against Scott and Allison's relationship, I felt bad that he wouldn't get a chance with her.

Mr Harris rang the bell again. "Time. If you catalysed the reaction correctly, you should now be looking at a crystal."

Matt and I both looked at our crystal, smiling to each other. Maybe I wasn't going to fail this class after all.

"Now, for the part of the experiment I'm sure you'll all enjoy..." Mr Harris continued. "You can eat it."

Matt held the crystal out for me. "Do you want it?"

"Oh, no, you can have it," I muttered distractedly, watching Isaac and Lydia.

I watched as Isaac offered Lydia the crystal, the girl taking it with a smile. Except upon closer inspection I could see the Kanima venom coating the crystal, forming a drop that was about to fall onto her tongue.

"Lydia!"

Scott and I looked at each other, both of us having shouted her name at the same time. Lydia looked between us, her forehead creased in a frown. "What?"

I stared at her wordlessly. I couldn't use my magic here, in front of all these people, and Scott certainly couldn't wolf out and take the crystal from her. Which left us with only one option.

"Nothing," I mumbled, sitting back down.

Scott shot a pained glance my way before following my actions, sitting down defeatedly as we watched Lydia put the crystal in her mouth.

The air was tense as we watched her chew the crystal, my ears focusing on the sound of it splintering in her mouth. She tilted her head to the side, thinking, before shrugging and looking at her textbook.

I felt my stomach drop.

Well, shit.
