I don’t remember the title or who the author was but this is what I remember (Which is a surprising amount)
The pack have kicked stiles out of the pack and the sheriff goes to the loft and yells at them all that now stiles doesn’t have an anchor since he can bend blood and has already killed most or all of the alphas from the alpha pack even having a wolf pelt from I think Ethan so they call stiles to the loft and they do a ritual to bind him to the pack I remember in another fic from the same series that stiles is possessed and they get the demon out, or they think they do but stiles has actually just locked the demon inside him to ‘play’ with later
This is pretty much the whole plot
What Lies Within by Onlymystory (1/1 | 3,717 | E)
Stiles walked in the house, covered in blood, a wolf pelt around his shoulders and a terrifying smile on his face.
Stiles told John quite happily that he had a new pet named Aiden and wasn’t he pretty. John smiled and agreed that it’s beautiful—Aria taught him to lie well—and said he got called into work because Gerard was found dead.
He refrained from thinking too much about Stiles’ response that he still hadn’t received a thank you card for that yet.
John drove directly to Derek’s apartment. Do not pass go. Do not collect 100 dollars. And pray that it wasn't all in vain.
