Just saw this episode for the first time, and it really knocked me out. 3 words - compelling character development. I'm not invested in the this show for the long haul, so I don't have many preconceived notions regarding the normal flow of the episodes. I guess I shouldn't be surprised at some of the negative comments here. Reminiscent of many horror movie fans who get annoyed when the slice-and-dice stops for 2 or 3 minutes to actually understand what moves a character. I was completely pulled into the police/prison psychiatrist angle, and the slow reveal of his past. It's excellent story-telling without clubbing you over the head (so to speak). John Carroll Lynch deserved and Emmy for best guest star performance for this role.
