Theo Raeken was dead set on leaving Beacon Hills, after sticking around the hellhole for almost three years after he was pulled out of the ground. So dedicated that he spent three weeks planning the whole event so it would go off without a hitch.
Two things he didn't count on were:
a) Liam coming home early
b) Hunters kidnapping him as soon as he left city limits.
Eight months later, what Scott and Stiles found when they took out a new kind of hunter den was decidedly worse then they ever imagined. The chimera was broken down, mentally and physically, to be rebuilt into Monster, an obedient sex toy for the hunters to blow off steam with, daily.
As the McCall Pack's second in command and resident Emissary, it fell to Stiles to take on the task of reteaching their lost pack member how to be Theo Raeken again. In true Stiles fashion, he doubted whether he was up to the task, but luckily, Lydia and Derek lend their hands to the endeavor.
The nogitsune may be gone but what if he had left something behind in Stiles, something dark and evil that only Stiles knew about.
Stiles tried to hide this part of him from the pack. He wanted everyone to remember him as the happy sarcastic boy everyone knew and loved, but the pack only saw him as a liability; a weak addition to the pack.
So what if a villain took Stiles to get back at the pack and the only way he could escape was to embrace his darkness.
Would the pack change towards him and how much would this impact Stiles?
Set after season 3!!!
