Hear it from someone who comes from a family where parents are separated. Children always know, my brother and I knew it where we were five, 10, 18 and now we are in our 20s we always knew. Children are very preceptive they might block somethings out because of trauma unable to deal with it but in the subconscious level it always exists the truth is always known.
Adding to the list of bakwaas the writers are dishing out, there is no way a man that abusive could change this fast. Being an alcoholic is one thingnot alcoholics are abusive it is wrong to assert that, mostly they hurt themselves but Dilsher was abusive alcoholic and that is a deadly combination and men like that need to be in therapy for years they don't just meet a sweet girl and change. They have life long anger problems and are never easy to live with, even if they manage to control their demons it always will rear its ugly head so that is why they have to be in therapy and have to constantly be kept in check. And there is no way Rudra did not know his father was abusive.
Dilsher cannot be what they have made him out to be. It is all about integrity in writing your characters, they can be good or bad but they have to be consistent. Mala cannot be what she is made out to be, there is no way a woman who supposedly is so talented did not notice for fifteen years her second husband had a secret life behind her back. I almost wonder wouldn't it just have been better to give Mala a successful second marriage, that would have added more spice to the story. Tejawat could have been another character completely. Mala's choice would have been correct to leave, we would applaud her for making a life for herself, and her reason to not take Rudra with her would be even more cruel than it is right now considering no matter what they say about Dilsher who would have wanted Tejawat for a father. Instead of trying to white wash Mala's character they could have just made her a realist instead of trying to feed us a story that is just not believable. I don't mind Mind Mala I wish they would stop justifying her. The same with Mohini they don't try to justify her she is who she is and that is acceptable. Does Rudra need to accept and forgive Mala for us to move forward, are the writers thru Paro telling us that is what they want us to believe because honestly I don't see it no matter what sob story they tell us.
