Interesting to watch the Tim v Joel battle at the moment..
You could say that Joel is the 'leader' or most influential of the newbies when it comes to voting atm. He appeared to be the most prolific/instrumental person steering votes against Drew whilst Tim was pro Drew.
Yet Joel didn't say much in the nominations room unless directly asked by Sonia, whilst Tim freely took the soap box to spruik why Drew should stay. Considering there was 2 swing voters that night, you think he would have spoken up more or at the least - rebuked Tim's comments, yet he remained silent (although as we know it could have been another crap edit by BB). Tim's last minute speeches might have been what swayed both the girls to vote Mel??
At least now we know that Joel is hell bent on demolishing the OG's asap, lets see if Tim can orchestrate a pre-emptive strike - not necessarily because I'm pro-OG, I just want to see some fireworks ... I'm thinking Joel wont give in so easily at the next few challenges, he'll be hungry for that nominations power to put up OG's... I wouldn't be surprised if when he next wins he puts up 3 OG's to ensure one of them is evicted..
They should know by now that 'safe' votes don't always work, we've seen plenty of times in BB & Survivor (as this BB voting format with challenges etc is virtually the same) invaribly ends with the safe vote being tossed out the door..
Maybe they should consult Johnson & Johnson - the self proclaimed super fan and best player ever

of BB.. and ask his advice...
