yes I thought Het's school tactics were like every other little girl of the same age (dd is a millenium baby). They all do that at 5/6.
I think the mother of James/Bernie was not completely blameless as at one point, she admitted that she had reinvolved the violent bloke with the family (but still a very sad situation).
I too was appalled by William - but you could see he was going to turn out that way a few years ago (I think in one of the programs where they thought he was trying to be the alpha male in the house). As for the program saying they thought he lacked attention, I always got the impression that he got the attention and the twins didn't!
