How paul fisher is similar to and different from his mother, mrs. fisher (tangerine) ?

I don't see many similarities between the two: only differences. Paul's mother is all about appearances. She likes the big house with the perfect lawn. Paul is not interested in superficial appearances. Paul is loyal to the people he likes. Paul's mother cannot even be loyal to her own son Paul. She lies to him about how he became blind. She also protects and enables her sociopathic son Erik.
