Dipika is manipulative (probably due to her training in soaps) and changes herself according to the situation. Surbhi is what you see daily. Dont care if any of them wins or goes out this weekend.
Sure, Deepika deserve to win since this game require housemates to preserve themselves while advance with dignity. While Surbi knows one thing, this I can't lose, no matter what and the trophy is her's, this assumption of hers don't match her demeanor. If does any of this outside in any social setup she will end up in a mental rehabilitation center.
