Alioop, I don't mean to be answering for Sor Juana in this post.I think that if he was using the counselling session as a show of being a good husband trying to work on his marriage for the purposes of covering up murder plans that he would have a done a better job. For eg showing remorse and empathy towards Allison and allowing himself to be easily convinced to be subjected to Allisons 15 min sessions sharing her pain. Why battle with Carmel about not regressing if he had a plan at that stage to murder her. Would have been easier to say, yes Carmel that is a great idea and I just want to help Allison move forward and if that is what she needs, I will do it because I love her so much!
but.... GBC told Police who were interviewing him that they had been to see other Psychologists, but Allison seemed to like this one.
Not being the first experience he had with attending a Psychologist, he would be familiar with the process.
In that respect, do you think that he could have decided to go along and this time, try and manipulate this one ....to achieve an outcome that he wanted .... to get Allison off his back.
The Detectives would have been interested in interviewing these other Psychologists as well. That would give further insight into GBC and Allison as well.... if that is what they wanted.
