I just finished watching a ABC 20/20 episode, and it involved Slenderman!
I didn't believe it at first but I saw him, the episode was about two girls who were dead set on becoming the proxies of Slendy. And they tried to kill this girl....
It was weird hearing about Slendy on TV but I was excited!
The episode was called Out of the Woods if you guys want to see it.
(Eyeless Jack makes a cameo too)
