They really know what they are doing, by putting Bear uo every week they know his behaviour will only get worse. He doesnt have to stay on anyone's good side now, he will be on a one man mission to drive everyone crazy. He was talking to Saira last night and he actually said that this week he might not act like what everyone thinks he will. He said that because he is the one housemate that everyone can vote for obvious reasons, arguments will occur between others. As people will be have to find the smallest reasons to nominate others, so Bear said that he will just sit back and let others argue for a change.
I think he learnt his lesson the other night, there is point kicking off. He will just stir the pot a bit now and watch others turn on eachother. I really dont think Bear will be going home anytime soon.
