See me bare my teeth for you:

Gerard is done waiting. Two days after he tried to kill you you get a text from Scott saying that he approached his mother at the hospital and asked a lot of thinly veiled questions about Scott and his extracurricular activities, and both Erica and Boyd are absent from school. A day later they're declared officially missing. Scared for Isaac's safety, you convince Lydia to let Isaac stay at her grandmother's lake house in the next town over, just in case Gerard knows his usual routine. There is a lot of activity at your house, hunters (or contractors as your mother likes to tell you) come in and out of your house at all hours, and from what you've managed to overhear they are searching the entire town and surrounding woods for signs of Derek and his pack.

Then you come home one night after dropping Isaac off at work and the entire house is empty.

"Hello," you call out hesitantly, walking through the living room, unnerved by the quiet house. "Is anyone here?"

No one replies. You search the bottom floor and then the top and then press your ear against the locked basement door for good measure. You don't know the pass code-even if you did your parents are the type of people who would change it every month-but you can't hear any movement or voices from below. They really are gone. You call Lydia immediately.

"It's time," you say, grabbing the bag in your closet you've had ready for days and changing into your dark jacket and running shoes.

Lydia picks you up at the end of your driveway less than ten minutes later, pale and shaking, but she doesn't try to convince you out of what needs doing.

"What about Isaac?" she asks as you drive through the dark streets of Beacon Hills towards the railroad depot.

"He's at work until ten tonight," you say, thankful that Isaac has to close on Thursdays.

"You don't want to pick him up? We could use a werewolf, couldn't we?" Lydia asks shakily, turning briefly to give you a terrified glance

"No, I want him to stay out of this," you say. "It's better if I just deal with this myself."

"Allison, I don't like this-"

Your phone rings and you hold your hand up immediately to silence her when you see that it's Scott.

"Scott?" you say, hoping he's not involved in whatever is going down at the train depot. "What's going on?"

"Where is Gerard?" he says angrily, and you jump a bit at his tone. You've never heard him so angry before. "Is he at your house? Do you know where he is?"

"No, I don't-" you say, taken aback. "Scott, what happened?"

"He came after my mother," Scott says furiously. His voice is lower and you wonder if his eyes are glowing, if fangs are growing as he speaks. He sounds on the verge of violence. You'd never imagined him sounding like this. "He came after my mother. I-she's, I had to take her to the hospital." Your mouth falls open in horror. What did he do? Why did he-how- "And he's going after Derek now," Scott continues, voice shaking with suppressed emotion. "Do you know where he is ?"

"I-Derek lives at the railroad depot," you say automatically, not even considering for a second ignoring his demand. "But Scott, my family is gone, I think they're all with him, you can't go there, they'll find out about y-"

"I don't have time to worry about that," Scott says coldly. "This ends now."

"Scott, wait, don't-" you say before he hangs up and his phone goes straight to voicemail when you call him back. He must have turned it off.

"Shit!" you say, cursing yourself for telling him where you were going. Why had you done that? "Lydia, drive faster. We don't have much time!"

"What's going on?" Lydia asks fearfully.

"I shouldn't have told him where we were going," you say, gripping the fabric of your jeans in frustration, willing your body to stop shaking. You're so stupid, why would you think he would listen to reason when Gerard had attacked his mother. "Shit, Lydia, you missed the turn."

Lydia doesn't respond, her eyes fixed on the road as she ignores the warnings of her GPS to turn right at the next intersection.

"Lydia," you say, banging you palm against the dashboard in an attempt to get her attention. "Turn right here, we were supposed to turn on Elm."

"I don't...it's...it's this way," Lydia says, even as her GPS reroutes and tries to get her to turn around. Your phone rings-Isaac-but you ignore it.

"Lydia, the railroad depot is back there, this is too far," you say, as she continues to drive further into the dark warehouse district.

"But...it's not," Lydia says, looking at her hands on the steering wheel in front of her, as if she's upset at their betrayal. "Allison, that's not where we need to go, it's this way."

"What the hell are you talking about?" you ask, starting to get angry now. What is she doing? Is this some ploy to keep you out of danger? "Lydia, stop the car!"

Lydia doesn't respond and you grab at the wheel to get her attention. "Lydia! Hey!"

"It's this way," she says through gritted teeth, not even taking her eyes off the road for a second to look at you.

You let go of her and look into her face clearly. Is this another...does she know?

"Do you know?" you ask her, watching the light from one of the few street lights in this part of town travel across her face and disappear into the back of the car.

"Yes," Lydia says, biting her red lips in frustration. "It's here. I can feel it."

"How much further i-"

A gunshot rings out, and Lydia hits the brakes immediately, causing the both of you to pitch forward, only your seatbelt preventing you from hitting your head on the dashboard.

You both turn to look at each other in horror, before you scramble for your bag.

"Stay here," you tell her, peering out of the car to the building next to you with the fire escape. Perfect. You thought you were going to have to use Kate's grappling hook and possibly kill yourself trying to climb the warehouse across from the railroad depot, so this option is far preferable. "Turn off the car, the lights, I'll be back soon."

"Allison!" Lydia squeals, reaching forward to grab your arm before you can open the passenger door. She looks terrified. "Are you...are you sure about this?"

You don't have another choice. You both know this.

"Stay here," you repeat, and grip her forearm in an effort to be comforting for a brief moment. "If anyone comes, just pretend you're lost, okay?"

"Allison-"

There's another gunshot, and you don't have time for what she has to say, so you jump out of the car and shut the door quietly before heading straight for the fire escape. You don't see any security cameras in the area, thankfully. You're glad for your extra weight when you jump up to pull the ladder down from the fire escape. It takes a couple tries, but when you finally get it down it's easy to climb up the three stories to the roof, the adrenaline pumping through your veins preventing you from tiring, even with your heavy bag. The gravel on the roof crunches under your feet as you walk quickly across the roof to the other side of the building, to where the gunshots came from. The building is taller than most of the other warehouses that surround it, so when you get to the other side you have a clear view of the scene below.

Leaning over the edge of the roof, you see what looks like the middle of a confrontation between Gerard and Derek. Gerard has four hunters with him, including your father, you realize with a dull pang, and they seem to have cornered Derek's pack in a dead end below you. To your horror, you realize that Isaac is one of the figures standing beside Derek, and by the way he's holding his side, he's been shot.

You drop to your knees beside your bag and unzip it with shaking hands, pulling out Kate's sniper rifle and loading in the bullets while part of you wonders if it's really you who's doing this. This cannot be Allison Argent. But there's no one else here. Just you.

"You might as well come quietly, Derek," Gerard is saying, in that tone of voice that means he's trying to sound magnanimous. "It's over."

"If you think I'm going down without a fight then you're even dumber than I thought," Derek says, though he sounds pained. When you peek up over the side again, you can see that Boyd is barely being supported by Erica, who looks like she might start to cry at any second. Isaac is the closest to you and from this angle you can't see his face, but you know he can't look much better. Is this why he called you? So stupid, why didn't you pick up?

You slowly raise the gun and position it where you want it, finding Gerard in your sights. Your entire body shakes as you watch him smile smugly in close-up through the scope. You jerk back and try to swallow back the wave of nausea that passes through you. Are you really doing this? You have to, you know you have to, but your hands won't stop shaking. You will never be able to take this back. This will haunt you for the rest of your life.

Movement catches your eye as your father threatens Derek and his pack with death if they do not comply with their demands. Something is glowing on the street parallel to the one the confrontation is taking place on and you go completely still with shock as you watch Scott, eyes glowing yellow, head for the fight. You can't see his expression, but even his body language while he runs screams fury. He hasn't reached them yet, but the second he turns the corner he'll be in their sight and then there's no going back. You can't let them find out about him. This has to end.

You duck back down to the scope to lock onto Gerard again. He's moved up a foot, but it's an easy adjustment. But you have to be absolutely sure. It's likely you will only get one shot. You've never shot this gun before, or anything like it, but you suddenly don't worry about that anymore. You feel very calm. Your body has stopped shaking, is now still and ready.

"Kill the betas," you hear Gerard order the other hunters suddenly, his face aglow with savage triumph. Scott has to be rounding the corner any second, now, you don't have any time, you have to protect him. "First these three, and then we'll go pay a visit to Sc-"

You pull the trigger.

You don't miss.

Gerard drops so quickly you almost miss it. The crack of the gunshot ringing in your ears, you don't move for a second, looking down at his prone form because some part of you still expects him to get up. It doesn't seem very likely though. There's a lot of blood splattered everywhere. They don't show that part in the movies. It takes longer than you should to realize that you shouldn't just sit here and pull your head away from the scope to look down at the scene in full. There is dead silence below as everyone stares down at Gerard, at his body, but it only last for a second before your father starts shouting for everyone to take cover, if anyone knows where the shot came from. The hunters immediately duck for cover behind a dumpster and against the other side of the street, unlike Derek, Isaac, Erica, and Boyd, who just stand there gaping at Gerard's body. But that's not good enough, you have to make them go away so Isaac can escape. You fire several shots at the ground in front of the dumpster, ducking down behind when they try to look up and see where the shots are coming from, but eventually you hear your dad yell "Retreat!" and they all run back down the street and around the corner. For a second you're afraid they might run into Scott, but you can't see him anymore, and anyway, you're out of time.

You put your gun back in your duffel bag and head back to the other side of the roof so you can climb down the fire escape again. You're very numb, and you have to blink a lot to make sure you're seeing the stairs properly in front of you. At least you're not panicking though. That would make it hard to do what you have to do.

You jump down from the last step, landing on three points and wincing a little when you skin your knee. Getting to your feet is harder than it should be, it feels like your balance has been thrown off and things get a little blurry for a second. You take a deep breath and hitch your bag onto your shoulder.

Walk over to Lydia's car, you tell yourself. That's all you have to do.

To your credit, you try, you really do, but when you're halfway there when everyone bursts onto the scene.

"You!" Derek Hale says, looking at you with shock all over his face. The stomach of his dark blue shirt is soaked in blood, but it's darker than the blood that pooled out of Gerard's head. Maybe it's because of the lighting.

You don't respond. You don't have anything to say to him. Erica and Boyd's wary looks are equally unimportant. Isaac, though...you're almost afraid to look at him. It's not like you didn't think he'd find out, it's just...you didn't think he'd be there to see it.

"Are you okay?" you ask, dully, looking at his bloody side. Your voice is completely flat. It doesn't sound like you care at all. You don't, really. You don't care about anything right now.

Isaac nods shortly, and the unreadable expression on his face makes your stomach turn a bit. He looks like he doesn't recognize you at all.

"What," Scott says stepping out from behind Derek, horror all over his face. "Allison, what did you do?"

You don't want to talk to him. You don't want to explain yourself, tell him that it was for him, for all of you. You don't think he'd listen, and you don't want to hear what he'll say. You knew that he wouldn't like it, that he'd think it was wrong. He's right. You just don't really care.

"It's over," you say flatly, looking at him as calmly as you can.

"You," Scott says, shock and hurt all over his face and why is he looking at you like that? He knew what Gerard was. "You, why did you, I had a plan!"

"It was taking too long," you reply, and you have to clench your fists together to keep your hands from shaking. You don't want to be here anymore. You want to go home.

Home is probably not the best place right now, though.

"It wouldn't have worked anyway," you say, the edge of your vision going blurry again. You try to pretend it doesn't affect you. "He was going to kill everyone else first."

"You didn't have t-"

"What plan?" Derek asks suspiciously, looking between you and Scott accusingly.

"You were almost useful for once," you tell him coldly, because why is he even here anymore? You got rid of his problem for him. Shouldn't he be off trying to manipulate more innocent teenagers into becoming werewolves?

"What is that supposed to mean?" Derek demands, baring his teeth at you.

"It means you know what happens to people who screw with me," you retort, fists clenched at your sides. You do not have time for Derek Hale right now. You are done.

"Hey, enough!" Scott says, stepping between you two, but he's facing you, like he's trying to shield Derek . "Allison, stop it!"

It shouldn't hurt so much. You don't know why you care so much about his good opinion of you. You don't even know him that well.

"Then keep him on his leash," you say, contemptuously, trying to ignore the crawling of your skin.

"What did you just say to me?" Derek snarls, trying to shove Scott out of the way.

"Hey!" Lydia shouts from behind you, getting out of her car. "You leave her alone!"

You don't want her getting involved in this, and you try and signal her with your eyes that this isn't a great idea, but Lydia either doesn't notice or ignores you because she marches over beside you, face pale but determined.

"You leave her alone," she repeats, shoulders trembling almost imperceptibly underneath the dim street lights. "You don't know what you're talking about."

"You're the one who doesn't know what she's talking about, she just shot someone in the head!" Erica blurts out, looking far less confident than she's looked these past few months.

"He tried to kill her!" Lydia shoots back, starting to look angry, but you don't want to deal with this now. You're so tired and your head aches.

"Lydia, don't, let's go," you say shortly, taking her arm. She's surprisingly warm, or maybe that's because you're very cold, even with your jacket. "We shouldn't stick around."

The police were bound to be called eventually and what would happen if you dad came back and saw you here?

Lydia gives the rest of them one final glare and then takes you by the hand and pulls you back to the car. You feel very strange, and she says something, but you can't quite catch it. You don't dare look at Isaac- you don't think you could bear the guarded look on his face, like you hadn't braced your hands on his chest and rode him until he begged for release just yesterday. You shake your head to clear the muzziness and nearly trip over the side of the car trying to walk around it to the passenger seat. It takes more than one try to fit your duffel in (shit, did you even unload your gun?) and Lydia has to reach in from the driver's seat and pull it inside before you sit down. You lean back against the headrest as she starts the car so you don't have to see them all staring at you as she drives away and try to resist the urge to curl into a little ball on the floor. You try to focus just on breathing, and not vibrating out of your skin. You need to stay calm now, you try to tell yourself, but it doesn't come out that way and instead you think, I just killed my grandfather. What is that called anyway? you wonder numbly, grand-patricide?

"Can you take us to the motel?" Isaac says from the backseat and you almost jump because you hadn't realized he was in the car with you.

You turn in your seat and look at him carefully. He's holding your duffel bag cautiously, but it's too dark to see his expression. You're so relieved that he's here that you find yourself choking back a sob.

"Not with that you aren't," Lydia says firmly. "You're staying at my house tonight. They'll be looking at all the hotels."

You guess that makes sense. A sniper isn't something hunters are usually used to worrying about. "I have to tell my parents I'm sleeping over," you say, trying to figure out which pocket you put your phone in. You pull it out and nearly drop it, hands shaking stupidly.

"Here, let me," Isaac says, reaching forward to take your phone. He squeezes your hand before he draws back and you let out a pathetic shudder and sag back into the passenger seat for the rest of the ride.

You don't remember getting out of the car and entering Lydia house. You're just suddenly being half-carried by Isaac down the hallway to one of Lydia's guest bedrooms. He sets you on the bed and then turns on the lamp on the bedside table. You look around the room. It almost looks like a hotel room, impersonally empty with a picture of a lake above the desk in the corner.

"Are you okay?" Isaac asks you, sitting down next to you and looking at you worriedly.

His concern is such a relief you could cry and you bury your face in his shoulder. "Yeah," you say automatically, even though you're not sure that's at all true.

You pull him down to the bed with you and try not to shake. If you can just get through this everything will be fine, you know. You just have to fight through this horrible anxiety and breathe.

You manage it fine for a while, you're not sure how long, and then Isaac pulls back to look at you. "You want to change?"

"I didn't bring anything," you mumble into his shoulder, red, red, red blood behind your eyelids, burning into your brain.

"Lydia left some pajamas."

You don't want to move, but it's stupid to sleep in your jacket and jeans so you force yourself to sit up and unzip your jacket. Your hands get caught in the sleeves when you take it off and for some reason that makes you panic and shake.

"Allison," Isaac says, reaching forward to still your struggling arms. "Let me help you."

You take a deep breath and nod, feeling stupidly grateful not having to move while he pulls off your shirt. He leaves your bra on, even though you don't usually sleep in it, and instead pulls the long t-shirt with something about a charity run on it over your head that Lydia must have left you.

"I was going to tell you after," you tell him, feeling suddenly guilty about your lie of omission over the past few days. "After I...I just wanted it to be over first."

"Okay," Isaac says after a pause and you can't tell if he's angry or not. You shudder a bit as he unzips your pants and pulls them down your legs, clinging to his shoulders.

"He put a bomb under my car," you tell him, hating how your voice shakes, but hating even more how you're using that as an excuse for lying to him. You're not even sure it was a bomb anyway.

"What?" Isaac says, sounding horrified.

"He found out," you mumble.

"Jesus," Isaac exclaims, throws your pants on the floor and pulls you close, cupping the back of your head protectively. It's pretty much the last straw for you and you turn in his arms and pull him down to the bed.

Isaac makes a muffled noise of shock against your mouth, but you ignore it, running your hands through his hair. You need a distraction and you can't think of a better one than a desperate fuck in the wake of your grandfather's murder.

"Allison, wait-" Isaac hisses, pulling away. "I don't think this is-"

"It's good, it's fine," you say, pushing up his shirt, desperate for skin. "Just, c'mon."

Isaac moans a little when you give up on his shirt and grab his ass, grinding your hips up against his, but instead of doing something useful like taking off his clothes and fucking you, he rolls away so fast that you're left staring at the ceiling in shock.

"What-" you say in confusion, pushing yourself up on your forearms.

"Look," Isaac says, holding his hands out defensively. "Allison. This isn't...this just isn't a good idea, okay?"

"Why not?" you ask angrily and try and reach for him, but Isaac jerks back immediately.

"It's not, you're all," he stutters, uncomfortable and wary. "We don't even have any, you know."

"So?" you say, because you can't care about that right now, one time won't get you pregnant, why can't he just man up and not be such a pussy all the time?

He gives you an annoyed look and you grit your teeth to prevent yourself from saying something you regret.

"I just, I want," you say, shutting your eyes and despising the fact that he doesn't have a normal libido like every other teenage guy. "Can you just please -"

"Hey, hey, don't, just-" Isaac says, scooting closer to you and wrapping his arms around you so that you shake into his chest. "Later, okay? Just c'mere."

He pulls you back down onto the bed and arranges the covers around you while you cling to his side. "You okay?" he asks, kissing your forehead chastely.

You don't respond and just grip him tighter, God, you just murdered someone, how can this be happening?

Isaac holds you close and strokes your hair, letting you tremble against him without comment, even though you know you must be freaking him out.

"I don't regret it," you say after a while, voice shaking pathetically. "I don't, I hate him."

"I know, it's okay," Isaac says softly. You've never heard him sound so gentle.

"I need you," you gasp, clutching him harder, because it's true. You were so, you were so miserable before you met him, you didn't even know. You hated everything, hated living, spending most of your time waiting for the distant light at the end of the tunnel that was adulthood, but not knowing if you could hold on long enough until then. You lied when your therapist asked if you'd ever had suicidal thoughts. But there's a point to it all with Isaac, with Lydia, and he gave you that. He'll never know how grateful you are.

"Later," he says, completely misunderstanding, but you can't find the words to tell him what he means to you, so you just hold on to him and shake.

Later, much later, when you've gone blissfully numb again and lie limp against Isaac's side, Isaac says, quietly: "I love you."

You don't reply, because you're pretty sure he thinks you're asleep. You wouldn't know what to say anyway.

You don't remember for a split second when you wake-up, but the moment you open your eyes and focus on the floral bedspread of Lydia's guest room everything comes rushing back, blood splattering across your vision. Your stomach turns and you have to leap out of Isaac's arms and run for the adjacent bathroom before you throw up into the toilet.

You didn't eat dinner last night, so there's not really anything in your stomach, but you keep dry heaving until you're lightheaded and your abdomen aches. I killed someone yesterday, you think, clutching the side of the toilet with shaking hands. I killed my father's father. You had to, you know you had to, but you're different now. You always will be. This could be the beginning of something else, something dark. Give it time, you're you-

"Allison?" Isaac says, stumbling into the bathroom. "You okay?"

You nod shortly without looking up at him. He drops down beside you and rubs your back gently, hand feeling large and warm and safe over your t-shirt. When you're sure you're not going to throw up again, you wipe your mouth with a piece of toilet paper and turn to press your face into his neck. You're a bit embarrassed about your behavior last night, and incredibly grateful that at least one of you realized how bad of an idea it would be to have sex without protection. Getting an abortion would definitely suck. The nearest Planned Parenthood is probably in San Francisco and doesn't it cost $500 or something? That is not something you need to deal with.

"Okay, c'mere," Isaac says, lifting you up like you weigh nothing and taking you back to the bed. You wrap your arms around his neck shakily and that helps ground you. He hadn't believed you last night when you told him you needed him, but you do. You'll show him, eventually.

"What time is it?" you mumble when Isaac pulls the covers back up over you.

"Uh...9:30."

"I should probably go home soon," you say quietly, even though you feel like you might cry at the thought of it. The more you act like everything's normal, the less suspicious you will be.

"I don't think that's a good idea," Isaac says after a long pause.

"I don't want them to get suspicious."

Isaac's arm gives a little jerk of panic under you and you reach up to touch his neck steadyingly. You want to ask him how exactly he got onto that dark street with Derek last night, but you're pretty sure the answer is going to make you angry and you can't be angry with him when you've been lying to him the past few days.

"Allison," he says, clutching your wrist, voice strained with repressed panic. "Don-

You crawl up to press your forehead against his and kiss him gently. "Thank you," you tell him and watch as Isaac's face falls in resignation and shudders.

Lydia has similar concerns, but you know the longer you wait the worse it's going to get, so you make her drop you off before ten. No one is home when you unlock the door and you almost sob in relief at the reprieve. You hide your gun back in your closet and force yourself to take a shower even though you'd rather just curl up in your bed and not move for days. You have to be normal, you tell yourself. That is the only way you're going to get away with this. Your parents might not suspect you, but surely the police will interview you, and you have to have yourself together for when that happens.

You hide yourself under the covers of your bed when you're done and everything seems foreign. This doesn't feel like your bed, your room. This cannot be your body.

Far too soon, you hear the garage door open. You let out one choked-off sob before you stifle yourself in the sheet. You can do this, you tell yourself, breathing heavily. There is no other option.

You throw yourself out of bed and stare at your reflection in your mirror. You're far too pale, so you slap your cheeks a couple time to get some color into them. But other than that you look okay. Wet hair, pajama bottoms- you look like a normal teenager.

"Allison," your dad calls from the first floor. "Could you come downstairs please?"

Don't panic, don't panic, don't panic, you tell yourself as you exit your room and walk down the landing. Oh, God, you're going to be sick.

"Yeah?" you say, looking down at your parents in the front hall, trying to lean casually over the railing. You're proud of how your voice doesn't shake.

"Come down, Allison, we need to talk to you," your mother says, looking very grim. She and your father both look exhausted. They were probably out all night.

You try to fake an annoyed look as you come down the stairs, but you feel like your heart might leap out of your chest. Trying to hide the fact you're having sex with a werewolf was nothing compared to this.

What if they know? you try not to think. What if this is some elaborate trap and they're going to ship me off to some hunter reeducation camp?

"Come into the living room and sit down," your mother says quietly, putting her hand on your shoulder comfortingly. You feel equal parts shocked and horrified to see the grief in her expression. "There's something we need to tell you."

They tell you that Gerard unexpectedly succumbed to his disease. You probably react with more confusion than you should because you honestly didn't think they'd lie about the entire thing to you. It's probably a good thing, though. It must mean they got rid of the body. The police won't be involved.

"But...but I thought he had more time," you say, using that confusion and not the underlying anger at them for always lying to you.

"I know it's hard, Allison, but you have to be strong," your mother tells you, reaching over the living room couch to grip your knee. Her face is very stiff, like she's trying to suppress any and all emotion, and with an unpleasant jolt you realize that it's a disturbingly familiar reaction.

"I-" you say, and it's easy to let the tears come to the surface when you turn to your father, because you did this. This is your doing. "Dad, I'm so sorry."

Your father nods shortly, attempting to hide his grief too, just not as well as your mother. He really seemed to be getting on better with your grandfather recently.

You're not sorry, though. You're terrified at the idea of them finding out and sick at the thought of what you're becoming, but you're not sorry. No guilt. You're really their daughter, after all.

A/N: Okay, you all probably saw that coming, but this chapter was fun to write! Everything is weird and twisted as it should be, because for whatever reason I really enjoy making this as strange of a story as possible. Please review!
