Nina,
You write so well. I love your post.It is the same writer who writes for both the characters. one character is only about ego, and I, me and myself. the writers have done an amazing job showcasing that. the other one is about man of integrity and respect. They have done a marvelous job showcasing that as well.one one hand, when the first character expects the mother to ask for forgiveness, and yet again threatens in his sweet demeanor that she better not leave him ( did you hear the ominous background music when he said that?), the other character chooses to forget the bitter words she said the last time, and asks of her well being yet again. He easily forgives, and asks for forgiveness in advance, for he shall butt in whenever he feels she is not OK.And I think that's what he makes her promise in front of her house.
