As far as nandini's trauma is concerned in season 1 when she saw eklavya for the first time, her trauma resurfaced and she hugged karan out of fear because eklavya was an ansh lookalike . However later on she stood firmly against eklavya during kt's r**e track .
Then in season 2 when nandini saw rio showig her trauma once again and her reaction to it was completely justified . But bringing up rio then ansh's shadow infront of nandini repeatdly and recreating the exact same scenes from season 1 where ansh try to terrrfy nandini so she wouldn't file for divorce feels repetitive and pathetic .
While showing lovely memories, playing he song "tere bin" or using nakchadhi bandariya and muh chadha peepa evokes a beautiful sense of nostlagia , but these ansh related scenes only evoke a feeling of pure disgust .
As far as bringing rio and niyati to sn is concerned , i am on completely nandini's side. Facing a person daily who shares the exact face of someone who comitted such a heinous act is not easy for any woman.
yes I saw she’s promoting molkki I think she was the writer there too
