Theory No. 1: Jett Travolta suffered from autism, not Kawasaki Disease, and the family's denial of his condition led to the accident. Theory 2: Jett was left unattended and so his fall went undiscovered for 10 hours. Theory 3: Travolta and his wife Kelly Preston hired their respective gay lovers as family nannies, meaning that Jett didn't receive the specialized care he needed. Theory 4: The Church of Scientology did it.
