The BAU team suspects that a notorious street artist is involved when bodies end up in macabre graffiti art in Detroit on Criminal Minds. "The Night Watch" is the fifth episode of the show's 11th season.
There are times when the mind is dealt such a blow that it hides itself in insanity. There are times when reality is nothing but pain, and to escape that pain the mind must leave reality behind. - Patrick Rothfuss
