Sai's reactions were a huge letdown in this revelation track. As the daughter of a police officer, she must have reacted quite differently to BK & gang's criminal activities. Instead she wants them to be a part of Harini's birthday. If anything, those criminals must be kept far away from that small child. Sai keeps giving big lectures about right and wrong, and yet she couldn't' do anything to those criminals. Forget doing, she didn't even mention legal punishments for their actions. It was such a huge disappointment. This is why I keep saying that neither Sai not Virat are flawless characters. They have their own set of flaws which keep coming up when they face difficult situations.
