Swathi, very good analysis. Sumitra is really getting on nerves, hopefully rest of us agree too. She is sounding so righteous talking to Disha. She was maintaining relations with Dhruv even after his marriage to Gargi. Whatever the circumstances or reasons were for Dhruv marrying Gargi, she is not the authority to lecture.
Vidya, about people not letting each other talk in the serial is common with everybody, not only Disha. There are many episodes where this happens.
