I think when the truth will out dat rishi got married to tanuja rano will start blaming her...on which tanuja may 1st say dat raj told her to do dat bt as raj may forget so he will deny... so she will remember raaj's condition dat nd too abt his dieses...as she has promised raj dat she won't tell bedis abt his dieses nd not to give tension to family she will accept dat she did by herself dat will be more worse for her...
