I'm just having a hard time believing that Katherine is not screaming to high heaven for a phone to have some contact with her grandchildren. I cannot imagine her going along with this bizarre situation. She is either totally incapacitated due to a stroke, or this is all just a crazy publicity stunt.
She very well could be in need of rest... it would not be easy at that age to live with a teenager and two other children. (How old is Prince? 12?) It's also possible that she could have had a ministroke. They don't leave a person with a lot of visible damage, from what I understand, but over time and after having several of them, it would take a toll on a person. Many times a non-medical person wouldn't even recognize one. They are almost always followed by a 'real' stroke somewhere down the road, according to my doctor. Katherine's health is definitely in a decline, due to her age. It would be a miracle for her to live until these kids are grown.
As far as Michael's money, I don't think there's a snowball's chance in He77 that his siblings would get any of it, they are certainly not entitled to it. His children are his legal heirs, not his parents or his brothers and sisters.
This just sounds so crazy to me. What better way to publicize some upcoming tour, though? Get the Jacksons in the news and mention their tour. It's all just a little bizarre to me, I'm having trouble wrapping my mind around this family's shenanigans.
