Pasting from another post:
He is so manipulative and people are so dumb to not get him. So easily he got Ali to jump out of the house and for Pritam to start fighting for the captaincy. Both were so dumb to fall into his changul. Ali I had taken for no brains just talk but expected more from Pritam. I thought Pritam has a brain to think and he still couldnot understand the manipulation of how they just wanted him to waste his immunity. Such a dumbo. And on top of that Upen didnot get nominated also. Upen is a clever chap. But I do not like the way he plays like a sly snake hiding under the leaves. Hope Upen goes out soon - Punit and Upen - most manipulative people in the house. But Upen much much more dangerous becasue he can so easily play with people's mins and manipulate them easily.

And yes now the Diandra-Kari fight - again manipulated by Upen. I wouldnt be surprised if he is behind most of the misunderstandings in the house. His strategy is to go to the weaker person, become their "closest" friend and then strike by putting some keedas in their mind and causing conflicts with strong people.
Some would say he is playing the game well but I just feel its a very sleazy way of playing. Dont like him at all!
