Bit of a random, when im bored book, this is basically the idea that after the Nogitsune was defeated that Stiles kept the powers and just for this the voice in his head influencing Stiles to do bad things but he can stop himself from doing them. The voice isn't actually the Nogitsune though it's more of Stiles consciousness in a way fighting. I might include a slow burn if i feel like it could add to this but for now it's just Stiles hiding thw fact hes somehow took the powers from the nogitsune. This takes place in season 4 following the story line of the episodes from Stiles point of view. So chapter one will be as much as possible from episode one. Then so on for the rest of the chapters.
