Oh ruby it is done deliberately by writer,see she made sure Umair remained true to his vows post his acceptance of his relationship with Sadia. Never even once was he enticed by Zoobie.she tried every trick,including his favorite dress and all.He seeks forgiveness with open heart.Right or wrong--- in writers mind there is a image for Umair--which is very caring,egoistic but deeply emotional guy.He is insecure but accepts his mistakes without holding anything back.
When she asked him why did you finally believe me today...She says aaj kyun...and his reply was sachai samne aa gayi...
So writer thinks of Umair as masoom( bahut ajeeb analogy hai..but).
As per zoobie i feel writers consider her self centered and pathetic girl who has a victim mentality.she is sadistic and took pleasure in being some one who controlled Sadia's fate .she liked it how she could at will tell her dad to either behave nicely with sadia or be mean to her.She has no love for Ahmer--she is just thinking of ways to get back in god books.....it is all about herself.If you hear her dialogues,the writer is very sure to portray Zoobie as incapable of thinking of other people's anguish.
Even her father's death she thinks of as her own grief,not of her mother's or Sadia's. that makes her a very dangerous character....am not sure How writers are planning to redeem her,if they wanted they should have started in early episodes like they did with Umair and Ahmer.
Umair is unpredictable maybe that's why I always found him more dangerous than anyone else in the story. Maybe yes writer like you said had a image of him and stuck to his character throughout the story and that's why his redemption scenes are coming out better. He was honest to admit that he can't go back and change anything. That's a fact. Wish he does speak about her pain too in the last episode rather than his own regret and pain.
I am super confused about zubi. They make her look cunning still and pairing her with ahmer in the end will kill the charm of ahmer character too. I feel ahmer in last few weeks was shown in a much better light but all will go a waste if he accepts zubi. If she was really sorry then she would do the right things now not blackmail him using a knife
.I want sadia to know zubi truth. Sadia seems to be running away from accepting her pyari sisters reality.
