Ermmm I think it makes sense for them to save Praneet, or atleast for Pritam to save Praneet because, they all know that Gautam will get saved. He's playing good, has audiences support and entertains the audience so he will be saved till the end no matter how many times the housemates nominate him. Pritam, could have been saved by Gautam, and I was kinda hoping for it too because Pritam has openly supported Gautam on most occasions, but its ok.. I mean its a game and one has to keep that in mind too.. Maybe Gautam sees Pritam as a slightly bigger threat to him compared to Praneet. I maybe wrong. As long as competition is healthy, these things don't matter..
