Mala left her son and Dilsher. So far we don't know why. But whatever her reason, she did leave them and ruined their life for these many years. However she did manage to save her own 15 years of life. While she did grieve for the loss of her son, she was compensated by her love for Thakur. And he provided her a good life. Also she adopted paro and lavished her maternal love on that child.
Now when Things are beginning to look uncomfortable with the Thakur, Mala is making her moves to leave him and go somewhere more comfortable. After all she knows her son is back in the haveli. Shouldn't the thakurain be standing by her man? She loves him after all. Love means good AND bad. Shouldn't Mala look to redeem the Thakur? Show him the error of his ways? Turn him over with her love? Bring him back from the bad?
Perhaps one way Mala can redeem herself for what she did to Rudra and his father is by showing some character and standing by this man, the thakur, who has loved and cared for her these many years...
what do you guys think?
