In 2-3 weeks, lot have clarified. Who is in top, who is playing what type of game. It is my observation.
Rahul - Playing very smartly and fearlessly. He knows how to separate himself from Jhund.
Ejaz - He is playing very cautiously, and in solo. He does not stoop down for footage. He is nice to everybody, sooner or later all girls will know him better.
Pavitra - She is not doing much, but zabardast bol bachan hai. Screen present hai.
Nikki (she is becoming repetitive) - She is playing dangerous game, but still getting screen time. She is losing her credibility by playing 2 faces.
Rubina - She leader of other group, she is getting some screen time by poking in everything.
Jaan - He is playing for survival, not doing much
Nishanth - Side kick
Abhinav - Useless, proving to be luggage of Rubina. He should play for himself.
Jasmine - Not sure why did she come to BB. Sabke lie khana banane??
In my opinion, Rahul is playing the best game. He might be looking bad to some of housemates but he is looking correct in his steps most of the time and always within the rule.
