He seemed to me to be heading for a breakdown though not because of what happened but more that this was the straw that broke the camels back.
I would have liked to have had more insight into his relationship with his mother who 'looked on' but obviously seemed powerless to help. It would be interesting to find out more about his feelings towards her. A friend of mine grew up with a very abusive/mentaly ill father and while she loves her mother very much, she always felt a level of anger that her mother didn't step to help her children even though she could see what was going on and the result over many years. Family politics

who'd have it?
