Sometimes, your own thoughts can consume you. When you refuse to give those thoughts consideration, they can take on a life on their own.

This skewed version nurtures fears of self-loathing and depression, attempting to drive Shawn mad, and ultimately, get him to end his life.
Will his brain snap, or is it possible to defeat your own subconscious?
