I wonder if Sukriti will tell Milind the truth about her raaz. If she loves him as she says she does, she wouldn't want to see him in pain, would she? And the poor guy is in torment. Sukriti cares for Prachi as well and it's obvious she wants them together. remember what she told Prachi when the latter came back with Milind during the floods? That only Prachi could find him and bring him back safely. As though only Prachi had the 'haq' and power over him.
So, if she wants them to be together, she ought to spill the beans. Here's praying the she won't be selfish and keep the truth to herself.
