It is his son, he's just a cold hearted who blamed his wife's death on a child. I literally dislike everyone except for the Orphe siblings.
I think he is too soft and limp wristed but I dont blame him his father had everyone bully and isolate him. And was constantly emasculated by his family and even his sister when the prime attention and focus always shifted to that butch shrew.
It would break anyone's self esteem and ego.
Is a butch obnoxious shrew and brother has been emasculated by the "father" because I think the Duke suspects or knows that he isn't his son. Look at their appearances.
