Stiles has been missing for over a year. When he returns he changed. He has a new name, new identity: Mitch Rapp. Everyone is really confused about how he changed and Derek likes the new Stiles, maybe a little too much.. OMG I'm even confusing myself with when the story is set and who is in it lol. Kay so around season 3A. Allison is alive, Alpha pack will never happen. Might have some events from all seasons.
