I went through the folder labeled SLENDERMAN first. It seems I didn't have to worry about Donnie knowing about Slenderman at all. He already knew.
The first thing I found in this folder was a file from a missing persons' case. The file was signed by Donnie's father. The victim?
Apparently, when Donnie was only 8 years old himself, he began telling his father about a strange man in a suit that was following him to and from school. The file states that the man who was following Donnie was described as "an exceptionally tall man with long arms, no distinguishing facial features, and always appeared in a suit." Donnie soon began drawing and writing strange pictures and messages. Those were included, but out of respect for Donnie, I am not posting any of the files from his package. Simply put, his messages all said the same thing "He's C(X)ming F(X)r Me." The drawings were of a little boy and a tall man with no face reaching his arms towards the boy.
One day, Donnie never came home from school. His teachers said they saw him leave, but that he was walking away with a man in a suit. They assumed it was his father. Donnie was gone for two weeks before he was finally found. At the lake. He was unconscious, but breathing. When he finally came to, Donnie had no memory of what happened during the time he was gone. The case was closed, and never looked into again.
The next things I found in the file were all internet pages printed out. The original "creation" of Slenderman on SomethingAwful, screenshots of the Marble Hornets videos, and even a list of blogs that people who have dealt with Him. The following names were the ones who stuck out the most to me.
Dr. Cairo Zelphest
Jeff The Keeper
The London Librarian
Damien and The Arsonist
Donnie knew about all of them. And I have commented on most of those blogs myself, so there is chance he knew about myself as well. But why didn't he come to me if he knew?
The ones that were highlighted, though, were Zeke Strahm, Celeste McLachlan, Specter, and Nightcrawler.
It seems that Donnie did know about the FBI and Fisk, if he has read Celeste and Zeke's blogs. He knew what was going on. He knew he had to hide everything. That's why he sent the files to me.
There was one last piece of paper in here that I was shocked to read. It was simply a note that read as follows:
DO NOT TRUST FISK AT ALL! THE MINUTE THE FBI COMES FOR YOU, RUN!
He doesn't need to tell me that twice, hehe.
Gonna go through more of these missing persons files after work tonight.
