After last night's episode, I'm not surprised that Sana is losing fans. I'm one of those people who is finding it difficult to defend her anymore. I have concluded this much about her that she is not so innocent. There is nothing wrong in stating that her struggles in life may have enabled her into becoming a street smart woman who knows exactly what she is doing even if she often gives off the impression of a babe in the woods.
Whilst Pillu was going bonkers in the fight with Niketan, Sana continued to remain quiet although the whole fight was about her duties, thereby giving Pillu tacit support. She only spoke when Sapna accused Pillu of doing "Sana, sana, sana".
I always knew that Delu and Sana were not close to each other. Aashka was the glue that held SAD together. Now that she is gone, Delu is slowly becoming free to insinuate against Sana and Pillu's relationship. Her cautious nature and diplomacy have held her back from outright condemning Sana's actions.
Sana knows what effect she has on Pillu and she doesn't mind. She uses it to her advantage. I'm not saying their friendship has crossed a line. I do think though, that late night sessions in close proximity with a man who freely touches her and praises her incessantly does not look good for both of them. Pillu's career is over but Sana's strategy is making her out to be a less than decent person which can backfire on her career.
