I just heard her conversation with Ali on Live feed, she has become a little too overconfident for my taste...she doesn't feel isolated at all, she is the one making the choice to stay away and judge people. She keeps pushing people away with her misplaced arrogance. It is a game show, if she gets to make choices, so do the others...nobody is favoring another. She's still in the house because of her very strong PR, good for her. Expecting other contestants to be nice to her even when she's arrogant doesn't make sense.
Coming to Gautam, he brought it upon himself as well, but he was genuinely nice to the people who stood by him. And now is trying to mend his ways with everyone for whatever reason. Even the fan favorite was reprimanded by Salman for putting everything in a negative light and he's mending that as well.
She was downright arrogant on so many occasions and when people retaliate, that becomes unacceptable. And why should she feel isolated? Only girls and Upen are kind of miffed with her behaviour. Praneet, Preetam, Puneet and even Gautam are fine with her. She spoke to Ali for a good half hour and spent time with Dimpy and P3G as well...according to LF
