Am I the only one who's noticed how most of these characters were brought up by the world's cruelty? Jeff the Killer was unleashed after sociopaphic bullies burned his body, Sally was raped and killed by her uncle, Laughing Jack was left to witness his only friend turn him into a demonic killer (the first of which was driven miserable by his parents by the way), Rap Rat was brought about when a Haitian mother lost her daughter to a sweatshop which the company who owned it refused to apologize for, Cid was an autistic boy who became corrupted by terror, Toby was an abused child who was driven insane by Slender Man, BEN was murdered, the list goes on!
Yeah, so Cid had developed an obsession with cutting tapes, and making some original content to add in. Eventually, he began embracing his fears, and started making his creations more and more disturbing. After the narrator gave up on him, he began finding those aforementioned Lost Episode Creepypastas, and Cid came to him again. This led to a visit to Cid's old house, and let's just say so that I don't spoil it that, Cid REALLY lost it.
