DISCLAIMER: I'm not intending to hurt anyone, but these are my thoughts.
I posted this on the AnuPre AT and thought this summarized my opinion about the character redemption of Anurag Basu.
I'll first talk about the engagement humiliation. Prerna finds out Anurag is getting engaged to Komolika. She runs to his house to see that the guy that she trusted so much is getting engaged without even telling her why he dumped her. At first, Anurag stays silent when Mohini and Komolika are degrading her. She continually asks him why he's doing this. After that, he finally decides to speak up and then BRUTALLY humiliates her. He even stoops down to the level of bringing her late father into the picture. This scenario was Anurag vs. Prerna, or rather Prerna vs. the entire world. She was left to fend for herself by a man who promised to marry her and take care of her for the rest of her life. He promised not only to her, but also to her mother that he would stand by her. Not only that, he slept with her and made her pregnant in the lieu of "saat din mein shaadi". Undoubtedly, Anurag's intentions were good, but I don't think I can forgive him for this act very easily. As a woman myself, Anurag's actions also insulted me, because he insulted her character (EVEN if it was fake) and told the world that Prerna was out to trap rich men. Even if he didn't want to confess everything to Prerna, he could have done a private humiliation or at worst only had family there. But he did it in front of the world, where lots of friends, probably Rajesh's former co-workers, media were present. In my opinion, Anurag's intentions do not justify his actions.
Now coming to the PreVik fiasco, Komolika spikes Prerna and Vikrant's drinks and they go to a room where she has installed a live camera. They are both not in their senses and some of the actions are portrayed to the world as if they are having an affair. Anurag finally speaks up when Komolika is attacking Prerna's character and says that he believes her. This scenario is AnuPre vs. the entire world. He defends her and brings her honor and "izzat" back.
The difference between the two scenarios is what I've bolded - Prerna vs. the entire world or AnuPre vs. the entire world. There is a huge difference between those two situations. In the engagement humiliation, Prerna was left all by herself by a person she loved and trusted. Before anything, Anurag was her friend, and he didn't even respect that relationship. I still can't get the visual out of my head where Prerna was lying on the road outside of BB after the humiliation. On the other hand, now Anurag has grown a spine and defends Prerna so that she doesn't have to hear anything more from society. Both actions did humiliate her. However, I will argue that the first humiliation was more severe, because she had no backing and did not expect Anurag to react the way that he did. In the PreVik fiasco, she did not expect Anurag to defend her, but he still did, for which she was thankful. The second action definitely does not undo the first action, in my opinion. He needs to apologize to her and let her decide whether she wants to come back to him. Most importantly, he should respect that decision.
Wooh! That was a long post! Thank you for reading!
