Bodyguards, fake names and some home schooling for Blanket IIRC.  

Debbie - the mom - runs a horse facility.  A CA friend of ours lives near her and has been to her place, met Paris once.  Said they both were "typical" horse lovers which isn't necessarily a comment on personality or character. Lol.  Butshe has a nice day and was impressed with the horses and the dedication.

Purely judging by looks - which I know is stupid and unrealistic- it looks like the son with the least time with Michael is the most affected socially?  Maybe Michael was a good father if a weak man.

They went to Buckley School, which is think is a very exclusive private school.

You have to wonder who she could just walk away from them and never want any kind of relationship.

Or maybe not. The older two had each other and their father was less weird during their formative years.  Remember the youngest was dangled by the legs over a balcony. MJ was completely out of his mind the last few years. If he abused other boys, who knows what he did to his son.

IIRC She signed a contract.  She does have a relationship WP with Paris now.  I can't remember is she also Prince and Blankets mom?

Many pedifiles never abuse family.  I doubt he did.
