She is thinking with 3 week left in the show, may be she can get 2-3 more votes with her fake friendship.I think she thinks Gautam is as dumb as her to be easily fooled by her sudden change of personality. Any body with half a brain will see thru her. Right now it doesn't matter what she does for him to be in his good books. She has burned a lot of bridges pissed off a lot of people and crossed certain barriers to be likable again, at least for me.
