Stiles feels nothing but emotional repentance against himself, self-loathing and hatred spring within his mind and cling to his every thought. He knows what he has done and had no way of stopping the on slaughter of vivid images that leak into his mind of the lifeless body of a dear friend.
The way she smiled and laughed, the way that she used to cling to Scott and he would hold her in his arms with such care. Just in the same way that she hung in his arms as her body soaked with blood, her eyes blank in a stare that seemed to tunnel through him forever.
Lifeless blank eyes stared back into Stiles wherever he goes, even when his eyes are closed and his mind is trying to sleep. He sees her. He feels her presence. He feels the weight of her death sinking him into a deep abyss.
And every night it wakens him.
Sheriff Stilinski wakens to the screams of Stiles in the early hours of each morning. He hoists himself out of bed, yet when he arrives he is rendered useless. Malia taps on the window in the hall when she sees Sheriff, and he lets her in. Sheriff doesn’t want the weight of guilt to be upon Stiles, he never wants Stiles to think that he has failed his father, that he is helpless. That he is broken.
Scott knows, but never mentions it. He knows that each night Stiles screams because he can’t shake the images of dead Allison from his mind, he knows that only comforting arms and words that tell him it wasn’t his fault are the only thing that will fix the mess. But Scott has none to give. He blames himself more than anyone and can’t bare the thought of uttering her name aloud again.
So Stiles sleeps restless, tender arms and silent mouths are the only comfort for him. Though he blames himself he knows that he friends will not. He just prays that his screams are not that of a broken man but that of a broken past ready for rewriting.
