I think I found the scenes where Thomas was at home - not in competition quite interesting. He seemed very hyper, very restless, and a bit 'on his own' even when he was seen with his step-siblings. Obviously if you are unusually bright this makes social relationships harder, even when you're NT.
He reminded me very much of a relative of my partner's, who was a very bright, cheerful, chatty, egotistical boy - and then became a gloomy solitary misunderstood adolescent. And who, it now seems, has high-functioning autism.
But yes, clips that have been carefully edited, can tell all sorts of different stories.
I suppose a lot of these contests have a bit of dangerous edge to them, and can do as much harm as good in the long run.
