Chapter 1

(Request/suggestion fill for @AllieKat0602 )
Jim's dad returns and tries to start a relationship with him, but Blinky isn't having it. In this scenario Jim's dad is a cambion (kinda like a changeling/human hybrid, not mentioned in the show but still a thing) and knows that Jim is the trollhunter. Is James really back to reconnect with his son, or does he has something more sinister planned?

*In this scenario the heartstone was fixed and everyone stayed in Arcadia*
