Her ET video was quite convincing. Scary even. Heck, if she could have acted like that in movies she could have been an oscar winning actress. That was good stuff. She obviously could be strong and mean when necessary. Why ANS insisted on playing the dumb blonde with the baby voice is unclear.
Anyway, it does seem Virgie is being judged rather harshly. At this point, it seems unfair. I am withholding judgment -- so far -- given the fact that she raised Daniel for her all those years and seemed to want what was best for ANS.
Mixing certain drugs, especially the kind that affect your thinking, can have the affect of making a person very angry and delusional. I suspect that is what was going on with her at that time. And Howie called ET in right away to capture the moment.
Even if it wasn't ANS, a known druggie, you'd have to assume that a person that had just lost their son, what a week or two prior, would be on some drugs. And yet nobody questioned if she was on drugs when that video of her "wishes" and "hatred of her mother" was made.
Anna was on antidepressants for sure. valium, most likely. Pain killers, yeah. Only G-d and at least one other person know for sure.
