I had an idea for a protagonist in a fanfic I'm currently working on.
Essentially, my protagonist wakes up from a coma and has major Identity Amnesia
, to the point where he cannot remember anything meaningful about himself. He is quickly pegged as being a slightly brain damaged important in-universe character by nearly everyone in the story, with some changes in personality, thought process, and social skills presumed to be a result of an encounter with an Eldritch Abomination
. However, I plan on revealing that the protagonist never was this character, and was instead a human incarnation of said Cosmic Horror
. I plan on trying to foreshadow this by using some of the changes in personality that the protagonist displays, but do you guys have any advice to avoid ass pulling
