HERE IT IS! The FULL LENGTH TRAILER!
>Sterek 3b plotline AU:
When Deaton mentioned a darkness, Stiles thought it would be as small as not getting sleep or feeling sad at random times but he was wrong. After waking up he finds himself having terrifying dreams where he is the monster. Once the dreams get more real a demon finds him and convinces him to let his inner demon take over saying he can control it, and like everything else in his life it ends up getting out of control. He turns to Derek because well Derek is always the one to save him.
Scott you’re my best friend and I need you. Scott, you’re my brother.
(i’ve said it before and i’ll say it again, the main season 3 mystery so far is how the hell we made it through two full episodes without a single character mentioning stiles’ summer transition from ‘kid with potential’ to ‘sex on legs’. consider the following my attempt at rectifying said situation. featuring oblivious!derek, incompetent-flirter!stiles, and scott ‘saves the day’ mccall.)
That night, Derek can’t sleep.
It’s not because of Isaac, who’s out cold on the couch, his breathing fast and shallow. It’s not even the lingering sense memory of burning flesh (Scott’s, just Scott’s, no one else’s, and he’d wanted it, asked for it, asked Derek for a favor, for help, and for the first time in months Derek had felt a glimmer of hope for his pack— bleak and brief, but a glimmer nonetheless). Both of those reasons would be understandable. Acceptable. They would make sense.
Thing is, they’re not the reason.
Derek can’t sleep and the reason is Stiles.
The True Alpha, everyone.
#yes here it is #i have this headcanon actually #where when stiles was a kid #he used to always be snooping in on things #his dad at work #his parents’ conversations at home #and he was horrible at hiding #just absolutely awful #but they always humored him #his dad pretended not to notice him hiding under his desk#even when the other deputies would come by and raise an eyebrow and point silently at his hand or leg or butt poking out the other side #he would just wave them off with an ‘i know’ kind of face and continue their conversation #his parent would share little sidelong glances at wherever he was hiding #under the coffee table or behind the tv#and gradually move the conversation to ‘i wish stiles were her to enjoy this delicious chocolate cake’ #or ‘now if only we could find stiles we would take him to the park to play with scott’ #and share a laugh when he would squawk and scramble out from where he was hiding #when he would play hide and seek with his mom she would always walk around going ‘where’s my little boy?’ #even though she could hear him giggling from inside the pantry or under her bed #and would always be surprised when he crawled out saying ‘i’m right here mama!’ #and because of all this #he has a very distorted idea of what constitutes as ‘sneaky’ #stiles sweetheart precious babycakes#all the stilinski family feels
