As a mother, to Sarika & Jaya, I think Rama failed this time. Why wouldn't she point out & remind Sarika that her answer affects her brothers & SILs life. If not @ that time but later in the night.
Sarika, a girl who grew up in family which values relationships failed as a sister. She broke her brothers home, a brother who would go at any length to protect her. She back stabbed her sister in law who was trying to help her by risking her marriage for a cheater husband who treats her like a doormat.
Watts is overacting but she is not wrong but she as a mother is there for her daughter. Rama has done nothing to protect her daughter/ daughter in law
