Peter/Stiles- Peter isn't actually Peter
Hi! I am looking for a fic where Peter is different after the fire. Stiles investigates and figures out that the real Peter Hale died in the fire and it is Peter's brother who survived. Due to the brother not being involved with the family much, it was assumed he was actually Peter Hale when rescued from the fire and in a coma.
He and Stiles end up together in the end.
Thanks!
