First of all I just want to say no offense intended, but I do not agree with you. I think nidhi is reacting quite normally. I agree she is a doctor, therefore compassion and service to humanity should be of the utmost priority. But, we also have to recognize that she is also a human being (a young girl, who is very newly married). It's a case of once burned and twice shy. Its normal to have the kind of douts and misgivings that she is feeling, but what we must rememberis, that at the end of the day, she does what is right. She overcomes all the lesser feelings and takes the higher path. We can be sure that, had the tables been turned Mallika would not have done that, she would have left nidhi at the side of the road, or even worse had her committed to a mental asylum, and gone back and told ashutosh nothing. So what nidhi is is or is not feeling does not matter because at the end of the day she did what had to be done, even though she knows that as soon as Mallika recovers, there will probably be hell to pay. Sorry, but that is my point of view.
Once bitten twice shy may be the case, if Mallika is normal... but here Mallika is in a pathetic condition (I havent seen but guessing from posts)... It should make a difference na.. not only as a doc, even as a normal being...
