I'm convinced it was a fix not the whole thing just him, he dashed to the middle podium. The other results were random I think though. I really don't see them risking a HM like Jack in this random situation. And although he came off disappointed he handled it fairly well. I got the feeling the SHOWBIZ mantra was staged so he would come off as annoying to the audience and we would not be sad to see the back of him. He seemed overly annoying for someone who has been in the industry for so long to be quite so awkward.
The main reason for this whole thing apart from a launch night twist I think is to put the HMs on edge and set the scene for the series. BB likes to mess with their minds, if it was for real fine, but this series is set to be one where the HMs will be messed with big time.
