Indira is emotionally blackmailing Rishi that she will take treatment if and only if he marries Shweta. Now, in just simple words, my query to Rishi is : Why can't he force Indira ??? As Indira is emotionally blackmailing Rishi for marriage and putting unacceptable conditions before him. In the same way Rishi can also put some conditions before her. Like Rishi takes a Knife/Blade and threat her to cut his hand impulse or he may also threat her if she is not agree for treatment then he will drink poison and will die before her. There are many similar situations which Rishi can put in front of her that he'll die if she is not ready for treatment so that she has to agree for sure……
