Sandhya always supports bhabo whether she is right or wrong. She believes that Suraj have solutions for all problems. Sandhya did not object or agreed to the baby donations.Suraj made the decision about baby adoption and bhabo agreed to it because of Bulbul remark about Bhabo has a part of Sandhya which is Sandhya's kidney. Bhabo had told Bulbul that the baby is part of Sandhya and she cannot give the baby to her so Bulbul gave Bhabo a answer which stunned bhabo.
Bhabo also considered a baby as something that can be donated.
Sandhya should have objected to the baby donation.
Ankhur is right in breaking all ties with the Rati and keeping Vansh away from them. They gave up Vansh without Ankhur asking for him. No matter what the Ratis does to Sandhya her loyalties will always be for the Ratis especially for bhabo Suraj probably has a screw loose.
