My guess is that bigg boss manipulates the votes, there's no way that Sunny would have got more votes compared to shraddha, sunny is not even entertaining at all, vida was the same way but she used to get into arguments too, whereas sunny can only be seen struggling with words. Bigg boss spent a big booty on her bringing her from USA, so definitely they want to vasool the money by keeping her in the house for more time. When Mahesh Bhatt went inside the house, it was simply a publicity stunt to promote their movie before it was produced, also that way bigg boss got the chance to promote sunny too. My question is that why was Mahesh Bhatt allowed inside, he could have waited for a month until the show ended, he must have definitely given money to let him inside the house, why such biased nature towards Sunny, may be mahesh Ji took care of all expenses bigg boss did on bringing Sunny. The tasks in the house were also related to Sunny and this shows that something is fishy. Shraddha couldn't have got leas votes than Sunny, if sunny had left, bigg boss would have been in losses as then she would have immediately gone to mahesh camp, whereas by keeping her they will try to show her in some sort of love angle with Sky which isn't happening yet from her side, this time a love story is seriously missed compared to all seasons, and looking into all these aspects bigg boss must have manipulated the votes. Another reason for keeping might be to strengthen Juhi's group as if sunny had left, then there would have been only Juhi, sky and may be shonali in their group, the other group has Amar, Sid, and Mahek, this way Sunny is like a trump card Whig bigg boss is trying to play by keeping equal members on both sides.
Last week when Sunny was talking to sky about her fans, it was funny to see that she thinks 20 million people know her, we didn't even know her before she entered the show. If every member in the house has about 2 or 2.5 million fans, and she thinks of having 20 million fans, then it is obvious to know why she is famous, we don't want to get in her personal life, but it's a pity to see her over confidence when she compares herself to tv stars and herself.
Last year bigg boss spent huge amount to bring Khali and he was horrible as he looked like a giant in between Lilliputians, he ended up in the finals and that too with zero entertainment, I seriously doubt the voting system. Imagine Shakti kapoor got less votes next to shraddha and sunny getting more votes, no way! Keep watching as they may show a love story to keep the trp which is falling day by day after PM's exit.
