had these images saved in my drafts for a while with the generic idea of Stiles straddling Derek in his sleep with the intention of killing him.
the reasoning being that someone [untrustworthy] had told Stiles that a Hale had killed his father. so for vengeance, Stiles seduced his way into the Hale castle, working his way through the family, befriending them, gaining their trust. he's got the face of a boy but the strength of a man, therefore he's often underestimated by his looks alone. so it comes as a surprise when Derek wakes up confused and somewhat startled to find Stiles above him with a blade raised over his head ready to strike.
just mere hours before they had had sex, Derek believing he had fallen for Stiles, trusted him entirely. they wrestle over the knife for a bit, thrashing in the sheets, a few nicks and cuts traded between them in fight over the blade as their limbs tangle now for completely different reasons Derek is yet to know.
once Derek does have Stiles pinned, the blade thrown across the room, and Derek’s grip tight around Stiles’ wrist, asking him, "what's the meaning of this? my love, what have I done!?"
Stiles' eyes growing misty as he spits and curses, "you had my father killed! blood for blood; I will have your head even if it means I die by trying!"
Derek’s grip loosens as he leans back from Stiles, eyebrows furrowed as he's grown even more confused. he admits to Stiles that he has no clue who his father is, "I would've done no such thing, I swear this.."
Stiles, of course, doesn't believe him. he flips Derek back against the bed, straddling him again and wrapping his hands around Derek’s throat, slowly adding pressure.
"I have no way of proving my innocence.." Derek says, his voice getting lower and breathier as Stiles continues to squeeze, "but if you believe i've done this, then take my life but it won't remedy anything."
Stiles’ hands get tighter around Derek’s throat, feeling rage but also now his own internal uncertainty because Derek seems earnest. he'd grown to learn when Derek’s lying and when he's telling the truth; a twitch in his ear for lies, direct eye contact when he's honest.
Derek blinks up at him, his face stoic and ready for certain death. but Stiles releases his grip around Derek’s neck, pushing himself away to the edge of the bed, covering himself with the sheets. his lip quivers, his breath catches, his quiet tears turn into full sobs. he feels now more unsure than ever and knows he's ruined whatever he had with Derek.
he's fully expecting Derek to have him taken away and killed for his attempts. Stiles is genuinely surprised when Derek reaches for him, offering comfort but Stiles flinches away, apologizing profusely for what he's done tonight, rambling on about how he was convinced that it was a Hale that took his father from him.
just as Derek’s about to ask who told him such things, the guards bust into the room with Peter following in behind claiming to have heard the ruckus down the corridors. Stiles doesn't put up a fight as the guards grab him by his arms and drag him from the room despite Derek’s protests.
Peter smirks and tsks his tongue towards Derek, pretending to reprimand him for sleeping with Stiles and not knowing the boy's intentions or the dangers he brought to the family. it only causes Derek to immediately grow suspicious of his uncle but he doesn't have the time or anything to go by. his main concern is Stiles as he dresses and pushes past Peter to find whatever cell the guards had taken him to.
