I agree. I have a different theory. I really don't believe BD had anything to do with HD disappearance. She brought up the polygraph, NG asked what questions were asked. One was Did I have anything to do with her disappearance, which was apparently deceptive. I think she believes she is responsible, but can't answer yes, then try to explain. Her facial expressions say alot. I think she was reading about murderers and sadists because of SA and his desire to watch those kinds of films. I think she had a deep down feeling that something wasn't right and perhaps if she read enough she could decide if SA fit the profile. Problem was, he knew how to answer all her questions- creating an internal turmoil. She's angry about the comments SA made about HD being on drugs and promiscuous. She seems like an analytical person. Trying to explain what goes on in her mind and how she gets from point A to point B in and of itself probably makes her feel crazy or stupid, so she tries to oversimplify, which can make her look detached. I don't know, that's just MHO.
As for SA, I think he is as guilty as the day is long. The point you make about something happening the night before makes sense, especially when you read that SA arrives at work at 6:00 a.m., looks at his supervisor, gets a Dr. Pepper from the vending machine and leaves at 6:10 a.m. He had things to do. I don't think he planned on the cell tower pings. I think he thought he just pulled off the perfect crime and had BD good and snowed.
I hope we're all wrong and that she has been hiding out because SA gave her the creeps and thought he was up to something. Maybe wants to be certain BD is over him.
