Vikas, who appears to be well connected, does not really need to be in BB except for some other more intricate reason which may be to make sure Shilpa pays for all the troubles she has caused to telly industry outside.
Since things have been quite between the two players, here comes the BB who creates a task between the two. On top of that BB gives Vikas a secret task that if he wins he can be a contender of captain. Which means that Vikas will do anything to win. And the rumor is that Vikas has won the task. Shilpa who trusts some of the members of task would realize that they really are back stabbers. So, another defeat for Shilpa at the hands of Vikas with the help of BB
All this shows that BB, Vikas and other outsiders wish to crush Shilpa's spirits. They will keep her inside for as long as they want and keep doing the same things to her to continue to shatter her dreams. Therefore, it is almost certain that Shilpa will not win the BB11.
