I have a slightly diff view about Ganesh. He may be the only person apart from Julie who has understood the game and is playing it in his own style. It is not loud like that of julie's strategy but rather a wait and watch kind of game. He chose the one person he can call out to evict first without being caught in a fight. Oviya does not hold any grudges and is the least dramatic. So choosing her is a safe ploy. If Ganesh had chosen say one of the others, then all drama and backbiting would start. He chose oviya, made snehan happy to keep him off his back, told GayathrI she has a temper, told Harathi that her jokes literally suck at times, all this without making them turn against him. That takes some intelligence. Of course one would like him to take a stand but that has to come later when the competition becomes tougher. Doing that now will get him nominated and there is no saying what would happen if he is pitted against oviya and say julie. He is playing it safe for now until the gang is broken up is my guess.
Oviya unlike Ganesh is a natural and has a maturity that is refreshing to see. She also at times becomes childlike making it a plus for herself with the audience. Because it is natural to her, she does not have to play the game like others. The reactions of the bully gang, harathi, and Julie take care of her screen time without any special effort from her end.
Julie is learning fast. She has successfully put herself in the midst of the strongest group within the house that bullies thus ensuring screen time. She is planning her next move and doing it in their face.
Harathi will continue her rants and gossip. That is her ticket to stay in BB and possibly her strategy. Irritating bit BB loves drama.
Aarav and Raiza are the weakest contestants. Aarav needs an angle with someone to even have screen time. It was oviya initially and now he has realized that he will have to play it safe for sometime as his nomination would mean sure eviction when pitted against Oviya, Julie and for that matter vaiyapuri. So he is sucking up to the Bully gang to avoid nomination. He may not go far in thus game. Same with raiza. She needs an angle and aarav is that angle. She birches with harathi but can do little else.
The bully gang of course are either over confident or stupid. Bit of course loads of ego for no reason. All free loaders. They are slowly being cornered. Once someone breaks ranks, it will be all out war with them.
