I saw it, it was really good.
Basically they took him back to Bara, which looked absolutly gorgeous,
Several things this kid said were true, ir the planes landing on the beach.
They visited a local historian who couldnt find anything about the family name the boy gave, but it turned out that they only recorded local people and not people from the main land, They eventually found that iinfact there was a family living on the island called Robinson and they found the house he described.
They took him to the house - not telling the boy - and the poor boy changed in personality, he went all quite and sad. It was very emotional.
They even amanged to trace a family member.
Once they returned from Bara the boy settled down and didnt talk about his 'past life' very much and was much more relaxed and more of a normal boy.
It was a great programme and quite touching.
