Nice post Anu. This is my take on Sakshi. Sakshi has grown up fighting alone all the way up. She never had any true friends or any true relations. Somehow I feel the lover whom she says existed might have jilted her. So the hard environment she grew up hardened her and made her ruthless. She doesn't trust anyone. Her experience has taught her relations exist only for power, status and money.So she tries to keep all the 3 things to her at any cost. She doesn't love Raj that I am sure of. She cringes at his touch there have been couple of epi. Regarding Rajma her anger was not because the affair was there. But because she was fooled by Raj and she didn't knew it.
Now why the CVs are not showing Sakshi's story completely. This is my take on it. From the title I feel Hasina refers to Sakshi and not Durga. Durga thinks she has seen all of Sakshi in Payal rape case. But the crux of the matter is that she has seen very little of Sakshi. That's why her plans failed terribly. Sakshi was not shaken when Shaurya was paralyzed or Rajma affair was exposed. She dealt with it quietly.
Each aspect of Sakshi has to be a suspense, the way she turns around things needs to be a shocker for Durga. I mean to keep the interest in the battle it is very important that Sakshi is not fully exposed. Durga needs to understand she still has a long way to go to really confront Sakshi. Each card of Sakshi is different which takes Durga by surprise when she is in direct confrontation with Sakshi.
So I guess each aspect of Sakshi will come out only as story progresses.
It is not for nothing one of the tagline of the show says " Poora Kolkata jaanta hai Sakshi Goenka ko, lekin poori duniya jaanti hai Maa Durga ki taqat ko"
It clearly says the real match for Sakshi is Goddess herself or someone she decides. Sakshi has gone beyond normal human emotions.
Durga also would have become like Sakshi if she had married Shaurya. The conscience in her would have died as she will slowly but surely become ruthless. Because with conscience you cannot marry your sister's rapist.
