On this episode of Supernatural…
Sam and Dean attempt to track Thinman, who also is being hunted by the Ghostfacers.
The brothers learn Ed created Thinman as a way to keep Harry from leaving and living a normal life with his girlfriend.
Sam and Dean recall their youth, enjoying a moment from the past together.
The Thinman turns out to be two fans who take the killer creature to the extreme. Harry kills one and Dean kills the other.
Harry is upset that Ed lied, much like Sam is upset with Dean. Rather than get past it, Harry choses to leave Ed and the Ghostfacers.
