Yup Sudha is definitely not acceptable in the family's view and Baldev was probably forced into marrying Satrupa. Interesting thing though is that despite doing as his family wished he has never been forgiven for his relationship with Sudha and probably also for producing a transgender child with her. The child is a source of shame for the family and thus the terrible treatment they give him. Narottam seems to want acceptance from his family so puts up with all the abuse. Perhaps Sudha also has a motive for sending him to Lal Mahal. You feel sorry for Narottam but at the same time can't help wondering what's going on in his head especially when he says 'Vatsalya, I always wanted to be you'.
This is such an intriguing show.
