I think Baba Sehgal and Rakhi have got an unfair chance in this show.
Rakhi - she was evicted and came back after seeing 2 weeks shows as an external audience - so she now knows what to do and what NOT to do.
Baba - same goes for him... being an audience, he knows the tricks of the trade. Plus, he has entered in the second half so he is ahead of all the earlier members in the game . This is unfair against contestants like Deepak Parasher and Kash who were evicted too early
