Griffin believes no man is a complete mystery but him but there was this episode I watched and the killer had the guts to tell him he had nothing do u think he's really a mystery after all

Actually I don't find so. He's pretty easy to read. You can tell that he really dosen't like it when a killer takes a step progressivo, para a frente before him and if he thinks he's not goog enough he'll blame himself, but he's wrong. No man can save everyone from who they are, or what they are. :p
