I agree. I also find it pretty unbelievable due to very serious ETHICAL issues that any therapist would conduct therapy sessions with such a high profile client, currently in hiding over the internet, skype, or any other medium where it could possibly be recorded and copied. Confidentiality is taken very seriously with every client, and would be even more so with an infamous pariah like ICA.
When Mason reacted with the words "therapy" and "illegal", I never ever thought about a professional therapist or actual psycho therapy. I immediately believed that he was using his lawyerly instincts and in spin mode and I took "therapy" to mean her own therapeutic tool, not a professional one.
It is very clear by the way that she is talking that she is talking to an "audience", and most likely an audience made up of her "fans" and creepy hangers on that send her money and give her attention. Therapy is two sided and dynamic and would not consist of Casey sitting in a room talking to herself. A therapist did not give her this as an assignment in my opinion, it would be too risky.
No. This was all about adoration, perceived adoration, and the fame that she thinks she has and always desired. She is so disordered , it is so easy to see.
