I came here looking for this actually, what is wrong with Jett?? I noticed something wasn't right with him when he was just 3 or 4 years old. Every picture of him, he doesn't look normal at all. I noticed today as well that Jett was not mentioned at all, nor was he in any of the pictures shown, even those of the whole family.
I believe it has been discussed on the boards here before, that Jett has autism and because of the Scientology beliefs, they can't seek help for him at all, thus they don't admit that he has it, or anything...if that isn't what is going on with him.
Very sad!
