Matthew Grey Gubler directs some this shows finest episodes. Take this one: it was creepy, like old Stephen King novels/shorts, but without it being supernatural. The way he spins his tale without it being "hokey", but also keeping it close to being horror scary, and also keeping in grounded in the real world. Some of the other episodes try this, but don't really succeed the way this show did.
I really enjoy the way Matthew takes every angle and pieces together an episode that was scary, yet one of the most memorable episodes of this series so far. (The only other episode is when the victims are made into marionettes. I still shudder to this day, and will not watch it because it's so plausible, and horrific, that I'm terrified it could happen to me. But that's me.)
So, please, watch this episode again, and again. I know I'm planning on doing so.
