Stiles Stilinski is one of the nicest people you could ever meet. He is sweet
and caring. Loyal to the bone. Everyone sees him as the hyperactive teen with
ADHD and no brain to mouth filter. But like everyone he has secrets his are
just a little different from everyone else's.
"Hey Sourwolf!" He greets as he waltzes into the Hale house. Its pack bonding
night so the betas are already sprawled around the living room chatting about
their week and arguing over movies and pizza.
"Ugh what's the spaz doing here." Jackson groans as stiles enters the room and
takes a seat next to his lifelong friend Scott.
"He's pack." Scott groans looking hurt.
"He isn't a wolf." Jackson argues
"He is pack. Just like the rest of you." Derek finally butts in.
Stiles is fidgety, as they settle down and put Paranormal activity on. He
bounces his leg up and down and taps his fingers against the arm rest. Everyone
will put it down to him having forgotten to take his medication. The real
reason is much darker. His mind is spinning as he gets the familiar tingle in
his chest. He needs to get away. Fast.
"Guys I'm going to head home. I forgot my Adderal and I really can't sit here
I'm just going to bug you all." He is waved off by the pack who are engrossed
in the film. He heads out and drives away as fast as possible, his hands
shaking as he grips the wheel.
He gets home and runs straight upstairs thankful that his dad is on a
nightshift. He slips on his darker clothes and makes himself look good before
going back outside and starting up his jeep again.
He drives just out of town and parks his car so it is hidden from view of any
cars that may decide to stop. Ruffling his hair he makes his way to the side of
the road. It doesn’t take long for a car to pull over.
"Where are you headed?"
"I'm trying to get to Portland." He says, flashing his least psychotic smile.
She nods and tells him to get in. He is thankful that she doesn’t try and hold
a conversation. A little way along whilst they are still on back roads he asks
her to pull over as he really needs to pee. She obliges. Stupid. He goes into
his pocket taking out the needle before sinking it into her throat. He has
about 20 minutes before she wakes up. Stiles steps out and goes round to the
driver's side door. He pulls her out and throws her over his shoulder. He loves
the fact that people think he is weak. The lady is carried down the slope and
into the dark forest before stiles proceeds to try her up against a tree.
She stirs after a while, just as he has set his equipment out in plain view.
She panics and pulls against the restraints.
"Oh come on sweetheart what's that going to do" He says walking over and
running a finger down her tear stained cheek.
"Please don't do this." The woman begs
"I wish I didn't have to but I do." He smiles sickly picking up a small knife
to his right and kneeling in front of her.
"I have children!" She tries
"I don’t really care." He lifts the knife and makes a small incision on her
forehead just like he always does.
"What's your name gorgeous?" She cries harder before choking out her name
"Jessica."
"Well Jessica have you learnt your lesson?"
"YOU’RE A PSYCHOPATH" she yells, stiles just tuts and wags his finger in her
face
"Now now, I find that quite insulting. You see psychopaths care, they feel
things. Me? I prefer sociopath. Did you know that all my friends think I'm the
weak human? I know right how rude! They think I've gone home to take my
medication but really I'm here about to cut you up."
"Please. Please don't." She sobs
"Aw it's okay, really it's just one. big. cut" He smiles before plunging the
biggest knife into her stomach. He pulls it up and relishes in her screams
before aiming the point at her heart. The cries stop instantly as her body sags
and her eyes go lifeless.
-----
The great thing about being the sheriff son is that stiles can keep track of
the open cases, it makes him laugh the majority are either supernatural or him.
He learnt how to clean up a crime scene at a young age and has only got better
since. He knows how frustrated his dad is about that. The fact that there is
never any evidence at the crime scene. He's surprised the pack haven't got
involved yet.
Stiles sprays on more aftershave than usual, to cover up any lingering scent of
his extracurricular activities and heads back to the pack house thankful that
Saturday is finally here. When he arrives he hears them training in the back
yard so heads straight through, stopping to grab a drink before going out.
"Hey guys" He greets with a smile
"Okay that’s enough everyone go shower" Derek yells as he sees stiles. He walks
over wrinkling his nose at the strong smell of aftershave.
"You should as well. Did you bath in your aftershave?"
[Better than the alternative]
"I slipped and couldn’t be bothered to wipe it off." He smiles and turns to
walk away making sure to bump into the door frame to keep up appearances. When
he gets inside he sees the pack watching the news.
"The investigation for the Heart Breaker is still underway" "Another body was
found this morning by a dog walker who proceeded to call Beacon Hills sheriff
department. The victim found was Jessica Hill, 28 who was last seen leaving her
home in Beacon Hills late last night. If anyone has any information please let
your local police department know."
"Sick Bastard" Jackson growls
[Rude]
"Can we kill this guy yet?" Isaac moans
"Yeah he's out of control man." Stiles adds [I really am out of control]
"We will start looking into it. I don’t think its supernatural but if anything
we might be able to help out." [why can't you stay out of things]
The pack don't stay long after, They agree to meet up the next day where stiles
has promised to get some information out of his dad. Stiles sighs and flops
onto Dereks couch. Acting sane is exhausting no wonder peter just let himself
go.
"Why haven't you left with the others?" Derek asks
" I thought I would spend some quality time with my Sourwolf of an alpha."
Derek growls
"This dude sounds pretty insane." Stiles says referring to himself
"If I ever find him, I will kill him." [good to know]
"Well I'm going to go for a walk."
Stiles heads out and walks towards the preserve. His mind is cloudy from Dereks
threat. He has never cared for anyone. Sure he would protect his 'friends' but
he honestly feels nothing. He has never felt; Guilt, remorse, sadness, love.
Contrary to what people believe, he has never loved Lydia he just wanted to see
her under his knife. And then there is Derek who is confusing the shit out of
him. Does he feel something for him? If he does he has no idea what. He walks
for a while until he decides to stop and sit on a tree stump. He loves nature,
it always clears up behind him. He hears footsteps approaching which has him
reaching for the small knife he keeps on him. 3 guys come into view clearly
wanting trouble.
"Look what we have here" The tallest one says
"Are you all alone?" Another one asks. Stiles plays the part of the scared
teenager, getting up and backing himself into a tree.
"Aw we've scared him. Don't worry we were just looking for the killer. He seems
to lurk in here." The one stiles assumes is the leader laughs.
"Th-the Heartbreaker?" Stiles pretends to stutter
"Yeah." one of the men answer as he walks closer. Stiles pushes himself away
from the tree dropping the act and becoming the stone cold killer he is. He
tilts his head to the side eyeing the people in front of him.
"You found him" He says before he lunges forward and slits the first mans
throat. He's faster than them thanks to having to run away from a new creature
almost every week. The fight doesn’t last long soon the 3 men are laid in a
pool of their own blood. He notices a figure out of the corner of his eye,
noticing it is Derek he instantly puts his wall back up.
"Stiles, what the hell happened?!" Derek growls
"They came at me, They said they were going to rape me." He lets tears fall
from his eyes, he looks to the bloody knife in his hand before chucking it away
from himself pretending to be repulsed.
"Stiles looks at me it was self defence okay" Derek reassures
"Go back to the house okay. I'll take care of this" Stiles nods and runs off
towards the hale house.
Laughing inside that Derek is clearing up his latest victims.
When he gets back he heads straight for the upstairs shower. He doesn’t know
how long he stands there but it must be a while according to his wrinkly
fingers. He steps out and pours bleach down the drain getting rid of any
evidence that may decide to come back and haunt him.
He finds himself some of Dereks clothes and shrugs them on before going back
down and curling up on the couch. Derek comes in not long after. He doesn’t say
anything he just chucks the blade back to stiles and goes to shower himself.
He comes down an hour later with a scowl on his face.
"You put bleach down the drain." He states taking a seat next to the teen.
"I-I thought it would be best yano just in case."
"Why do you have a pocket knife?" [why do you ask so many question?]
"I run with werewolves, I wanted something that I could take with me."
"How did you fight off all three of them" Stiles sighs [fuck here goes nothing
or everything]
"I-I'm stronger than I look"
"Stiles cut the shit" So he does
"I've done things. Things no one knows about." He starts, Derek stares waiting
for more.
"Things I'm not proud of" He laughs his eyes seemingly turning darker. He leans
forward and brushes his lips against the alphas ear before whispering
"I kill people." Dereks blood runs cold. No he hasn't. This is stiles freaking
Stilinski. The hyperactive spaz who can't concentrate on anything for more than
5 seconds. But… his heart beat is steady. Like it always is. Even when he's… Oh
my god Derek thinks as he looks up to the boy in front of him.
"This isn't you talking" Derek snarls
"I'm not possessed sweetheart" Stiles mocks
"Stiles I think we should go and see Deaton" Of course he jumps to the
conclusion of a possession stiles' whole demeanor has changed. The sweet boy
now looks calm and collected like everything he says and does is calculated.
"I'm your mate aren't i?" Stiles says with a smile
"How did you?"
"I'm not stupid plus you made me feel something. I obviously didn’t know at
first but I do now. I know I know. woe is me why are all the people I like
insane." He laughs hysterically.
"Me though I'm not insane, I'm just a little crazy and sociopathic. Well maybe
a bit more than little."
"What are you talking about!" Derek growls
"You see, I would love to give you a traumatic back story but I can't! Yes my
mother was taken from me by some disgusting disease but I was already like
this. She caught me when I slit my pet bunnies throat. Rest in peace Fluffy"
"It's funny right? I always take the piss about you guys killing poor
defenseless animals when really that’s how I started. Of course my targets
became bigger. I believe you have heard of my work? They call me the
heartbreaker. It's funny because I literally break hearts… even children. But
that was only once not that it bothered me. It just wasn’t satisfying"
Derek growls and lunges forward, stiles is perfectly prepared to have his
throat ripped out… With teeth! What he didn’t expect was Dereks lips to smash
into his.
"Your disgusting" He growls through the kiss
"I know" Stiles pants. Derek pulls stiles into his lap and stares him in the
eye.
"You kill innocent people. You have killed more than peter" Stiles' smile turns
deadly
"I know." Stiles whispers, his eyes light up as he sees a smirk form on the
alphas face.
"I want to watch"

FAR THERE HAVE BEEN NO CONFIRMED WITNESSES. THIS BRINGS THE KILLERS BODY COUNT
UP TO 11 AND THOSE ARE ONLY THE ONES THAT HAVE BEEN FOUND. ONCE AGAIN IF YOU
SEE ANYTHING, OR WITNESS ANYTHING STRANGE PLEASE LET YOUR LOCAL AURTHORITYS
KNOW.}
"Jesus Stiles" Derek says as he closes his laptop.
"Want to know a secret" Stiles whispers whilst kissing up the alphas jaw
"there are at least 20 bodies that they haven't found." Derek groans and pulls
the killer into a heated kiss. Derek has absolutely no idea why he is finding
stiles' activities hot, he has always liked the teen, has always known that the
boy is his mate but after finding out his sick little secret he just couldn’t
hold himself back anymore. He should be repulsed but instead he's wanting to
watch how it's done. He isn't the weak innocent human the pack view him as. No,
he is a cold blooded killer and Derek has never been more turned on.
"Tonight come to mine at 6pm. Don't drive and make sure you don't look
suspicious. wear all black and make sure you have something with a hood. Do you
have leather gloves? Oh and by the way If you get me caught you will be the
next on my table." Stiles smirks as he does his jeans up. Derek gulps at what
he isn't sure.
"I don't have gloves" Derek replies taking in his boyfriends appearance.
"You can borrow a pair of mine" Stiles sends him a wink before walking out of
the bedroom and proceeding to leave the house all together.
Derek falls back onto his bed and lays there for a while just daydreaming about
stiles. He when he hears 2 vehicles approach and the voices of a three of his
betas as they get closer. He gets up and slips on a casual outfit, not
bothering to try and hide the scent of his new partner before heading
downstairs to greet them.
"Derek dude we need to stop this." Scott starts as soon as he sets eyes on the
alpha
"2 more bodies were found" Isaac adds
"I know but we have no proof that he is supernatural do we? Therefore not our
problem."Derek reasons
"We don't care. If the police can't find him we will." Jackson growls
"ENOUGH! yes the asshole killing these people is sick and probably needs his
head checked but there is nothing we can do. If we get involved it will look
suspicious. We are sitting out on this one okay. None of you will look into it
or do anything do you understand? If you go against my orders I will take it as
you challenging me." Derek deepens his voice on the last part and uses as much
authority as he can along with a flash of his eyes so his betas submit to his
orders. Isaac, Scott and Jackson groan but agree anyway before wrinkling their
noses as the strong scent of sex and stiles hits them.
"Why do you smell like stiles?" Scott questions.
"He's my mate. We finally got our shit together" He smirks making the betas
mock gag before practically run out the door and back to their cars.
Derek spends the rest of the day pacing around and trying to make himself busy
so he doesn't think about what the night might entail. He would be lying if he
said he wasn't nervous because in reality he is, he is also rather excited
which for him is somewhat unsettling. He can honestly say he will do anything
to protect his mate. Be it saving his life or covering up one that he ended he
would do it in a heartbeat.
Derek changes into a dark pair of fitted jeans, a black Henley, a hoodie and
his leather jacket before looking at himself in the mirror and giving himself a
once over. He pulls the hood of his jumper over his head before leaving and
starting the walk through the preserve to get to stiles' house. When he arrives
he is thankful that the sheriffs cruiser isn't in the driveway although he
doesn't think stiles would be stupid enough to do anything remotely suspicious
with his dad around. For once he doesn’t climb through the teens window,
instead he knocks on the door like a normal human would do.
"Hey man." Stiles greets before waving him inside and shutting the door behind
him. Derek follows stiles up to his bedroom and sits on the teens bed watching
him as he puts together the finishing touches.
"Comb your hair." Stiles says chucking him the comb before disappearing under
his bed.
"Why?" He asks confused
"Do you want any of your hair falling out and ending up at the crime scene?
Nope didn't think so." Stiles slides back from out under his bed with a black
duffle bag and smiles when he sees Derek doing as he is told. Derek hands the
comb back to his mate when he is done and leans over to get a look inside the
bag. Stiles pulls out two pairs of black leather gloves and puts on his own
before going over them with a baby wipe to get rid of any fingerprints that may
have formed when he handled them. He chucks the wipes to Derek and waits for
him to do the same. He goes through the bag quickly without pulling anything
out and when he seems satisfied zips it up and pulls it onto his back. Stiles
walks up to Derek who he can tell is actually nervous for once and pulls him
into a quick passionate kiss.
"Where are we going?" Derek asks as stiles makes his way out of the room and
down the stairs.
"We're going to go and find ourselves some happy campers." His smile is
sickening.

See the end of the chapter for notes
As they into the preserve Derek feels his heart begin to beat faster. Yes he
has killed people before but he has never actively hunted someone out just to
end their life. It's exhilarating. they come to a stop just out of view of a
tent. Inside there are two clear shadows. A couple, Derek confirms when his
sensitive ears pick up on kissing sounds.
"I want both" Stiles practically growls. His whole personality has become
darker, even Dereks wolf who still sees stiles as mate is uncomfortable with
the threat pouring from the teen.
"Take this, straight in the neck. You take the guy." Stiles orders handing over
a needle, Derek doesn't question he just follows his mans lead.
"Hey excuse me" Stiles calls as he approaches the tent. They hear a groan and
then the rustling sound of the tent being unzipped.
"Can we help you?" A frustrated guy asks
"Hi I'm really sorry to bother you but me and my boyfriend are lost and I was
just wondering if you could point us in right direction?" Derek is in awe at
the charming personality stiles is now showing.
"Honestly I'm not sure whilst its dark, Erm I think it's that way." He points
in the general direction to the right.
"Hey Katie come here." He calls to his girlfriend
"Yeah baby" She comes up behind him and wraps her arms around his naked torso
"These guys are lost which way back is it?" Whilst the couple are discussing
the wrong direction stiles sends a little nod to his mate and lets a smirk
creep onto his face.
"Why are you guys out here haven't you heard there's a serial killer on the
loose" His eyes seemingly turn darker. The couple chuckle right up until they
both have needles in their necks and are falling to the floor as the sedative
kicks in.
The next 20 minutes are a blur of dragging the teens and tying them to trees,
Derek watches as stiles sets out his knives in front of the couple so they have
a nice view when they wake up. Stiles approaches the man and kneels in front of
him before slapping his face and cooing at him to wake up.
"Hey buddy. how you feeling?" Stiles asks when the mans eyes flutter open.
"What- No, your-your him." He stutters, stiles nods and nods to Derek to wake
up the girl.
"So my friend what are yours and that beautiful ladies names?"
"T-Terry, Please don't hurt her!" Stiles looks to Derek who is knelt by the
girl and smirks.
"I like it when they beg. Derek would you beg?" Dereks eyes widen, not sure
which context to take it in.
"Yay she's awake!" Stiles exclaims as the girl begins to stir.
"Hey sweetie what's your name?" Stiles asks tracing the knife he picked up
against her jaw.
"T-Terry" She cries out
"Nope that's his name" He points to the tree next to her and sees her
physically relax.
"Theresa" Stiles nods and turns around to find his knives.
"Big, little or medium?" He asks without turning around.
"Big? okay" The victims are crying and wailing hoping that someone will come to
their rescue. Stiles looks to Derek who is watching his every move with
fascination. Stiles taunts Theresa as he starts to make little cuts on her
boyfriends face before he plunges the knife into the mans abdomen causing him
to cry out.
"Can i?" Derek asks distracting stiles who is making the mark deeper, stiles'
smile turns deadly as he nods and hands another knife to his mate.
"Into the stomach then drag to the heart. Don't be sloppy" Stiles says as he
uses all his strength to get past the rib cage then with 2 swift movements
removes the now deceased mans heart. Once Derek has finished his stiles
arranges them back near their tents in a sickening position.
Stiles doesn't really say much as they jog back to his house he sees locked in
his own little world, fantasying about the kill they just shared. When they
reach the tree line which gives them a good view of the Stilinski household
stiles holds his hand out and stops Derek from moving.
"Gloves off, hood down my dad is in." Derek obliges and puts the blood soaked
items into stiles bag, he watches as his boyfriend unzips his jacket ruffles
his hair, checks himself for any possible blood splatter and then heads towards
his childhood home.
"Hey daddio!" And there it is the flailing teen is back.
"Hey son where have you been? Derek." The sheriff nods when the alpha comes
into view.
"We had a pack meeting but I didn't drive so Derek dropped me off and promised
to help with my biology homework." Stiles grins and speeds off when his father
agrees without suspicion. Derek thought the whole homework thing was a lie but
apparently just like so many other things he was wrong, and after showering and
helping stiles clean up he now has the teen on his lap whilst they are
conveniently discussing anatomy. Stiles and Derek are settled and working
contently until there is a knock on the door.
"Stiles I have to go to work, don't go out without letting me know where you
are going." The sheriff says looking slightly defeated.
"Is it bad?" Stiles asks with a 'worried' expression.
"Double 187. Be careful when you're out and you Derek."
The sheriff leaves without another word. Derek turns to stiles looking slightly
panicked but is met only with a smug grin and a chuckle. Oh god what has he
gotten himself into.
