he will repent,it will be major part of story ruby ,but zoobie uska guilt use karegi us ke against .She only wants to hurt Umair,with her twisted mind she may do by making her sister happy with Ahmer,but sadia has crossed the bridge called Ahmer,for her zoobie's such efforts may backfire in my opinion.Plus she would never want to destroy zobie's marriage,she doesn't have a mean bone in her body.
Umair is selfish too, he to won't want sadia to get any happiness and the baby too is there. Why should ahmer take care of it. It's not his responsibly
I feel you are looking at the promo differently
It's got nothing to do with zubi wanting sadia ahmer together
