My thoughts on seeing this video, as a grandmother, is that, of course there were some good times and the room is very nice. So far, this is normal and expected of loving grandparents of means.
All of that is over shadowed by the unbelievable cruelty, of denying Sean of his wonderful father in the first place, and made so much worse by the venomous battle they put David through, just to be with his OWN son.
I constantly am mystified by the selfishness of abductors. She always could have spent time with Sean, at a visitor to the U.S. and under normal circumstances, David definitely would have allowed Sean to visit his grandparents and younger sister in Brazil. These abductors, have no concept of real love, where you put the best interests of the child before your own and surround them with ALL the people who love them.
