Having suffered a bereavement around the same time as Peter I would not expect him to ignore his brothers sad passing at all ..
Then why is it wrong for him to feature it in the programme? We all deal with grief in different ways. I've been bereaved too, and I'm sure people might criticise me for how I dealt with it. There's no right or wrong way to deal with grief, only your personal
He's a contract to fulfil, and if his brother's death was ignored, it would look bad. As I said, the bloke can't do right for doing wrong.
