I believe you are correct - Diana Highland. He was quite devoted to her. It was touching. I think I heard, not long after that, that he 'found' Scientology, in a period of personal grief, no doubt. Ironic, considering Scientology's beliefs about illness and treatments. He must have been 'polluted' (I think that's the word they use) by her, in their eyes. I was stunned, too. I remember my mother phoning me at college just to tell me that. She, too, was shocked - a good Italian American Catholic buying into an apparent cult. (I think she was also concerned about cults targeting vulnerable college students...)
Yes, I remember he was quite grief-stricken. I wonder if the treatments that she had to undergo turned him off medicine? However, would he allow a family member go without cancer treatment? Did he think she brought her illness on herself as the cult says?
He seems like a good guy. Too bad he got mixed up in that mess.
