Here's my clue:

No abusive father without an enabling mother. 

In this "special case" I also consider that Marolyn very probably strived to be 'The Number One Devotee' ... who thinks she's not even worthy of one glance of "her master". If misunderstood devotion were a medical condition, she would probably be stage V of it: incurable...

Now here come two other pieces of info (which I heard through the grapevin back in these days) which now fall into place:

1. Marolyn goes to Pepperdine University and studies psychology. (Maybe a hint of her Inner Being to try and make her aware of her own 'shadow'?)

2. Marolyn lives in her own house, away from the Residence (understandable considering the Ji openly and shamelessly lived with his mistress, Monica) ... and she is very sick with a brain tumor. 

Yes, in my eyes, these rumors fit into the picture of a severely disturbed person who is not longer able to "square the circle" of cognitive dissonance vs. (whatever she felt she couldn't let go of . eg. lifestyle probably a prenup which might have taken away her motherly rights in case she leaves him?).

And so on. It is utterly disgusting, and this family is one of the worst in the scale of "dysfunctional".
