<modsnip: Sleuthing MG and/or her children is not allowed>
Also, I think it is possible that MG could have had doubts all along yet continued her relationship and involvement with CD and LVD. We don't know her mind and her past (childhood etc.) and what her needs might have been. With CD and in particular LVD, she was given a tight friendship group. Within this circle, she had a place in a lecture circuit, podcasts, status of a sort. I can see where someone might quietly keep their doubts to themselves while enjoying the fullness of the life being given to them. Perhaps she was hoping that in time she'd be given further evidence of whether or not their teachings were true. She hinted on the phone call that she'd always had some misgivings and bad feelings deep down. Hindsight is perfect and it's easy to get caught up in things when they are providing for your psychological needs.
Years ago I was involved in some large group awareness trainings. For those who don't know, they are like Lifespring or EST. I saw first hand how one's mind and attitudes can be manipulated. For a short time I was caught up in it and then I saw it for what it was. However, many of the people I had met continued with these groups for years. These were not dumb people. Many of them were highly educated professionals.
