I agree April, I wonder how much anger was also focussed on June and Nevill for daring to bring infiltrators into the family and spend money which was rightfully theirs on the infiltrators? Makes you think really.
Maggie, other than monetary, he seems to have had very little interest in the Bambers' lives. He doesn't seem to know when Jeremy and Sheila were born. He gets the names of the twins wrong. There seems to have been very little by way of socializing between them. I would say that it's more than possible that the advent of Sheila and Jeremy created a chasm which widened as years passed. I can't imagine that Nevill would have had much affection for a man who denigrated his son at every opportunity.
