The Judge's Will

The relationship between the mother and her son is very odd to me. They're so close it kind of seems boreder-line incestuous. I guess that's the mother's way of trying to replace the loss of attention from the judge. The son, Yazi, sometimes gets outbursts or anger and she lets him settle down without yelling at him because I feel that she's scared to be distanced from him but that's not how a mother should act.
What's with these women dating men that are dating men so much older than them.
Binny seems awfully kind to the judge even though he's been cheating on her for years. I think he sees her maturity since they first got married. She doesn't need him or what he's left in the will.
