Pratigya in `Mann Ki Awaaz Pratigya 2` took a major step for her family after she was told that she is suffering from blood cancer. She made sure Krishna felt that there is something between her and Aadarsh and so he would leave her and marry someone else. And it worked. Her plan was successful as Krishna married Meera. 

This was all planned by Amma ji. She was the one who started poisoning Pratigya and made the doctor say that she is suffering from blood cancer and has a few days to live. But Pratigya figured it out. She got to know that Amma Ji was behind all this. And made a plan so that she confesses it. Well, she ensured Krishna was present while Amma Ji says it all and the truth was finally out. Krishna got to know why Pratigya was behaving the way she was.
