I knew it!
I knew BB would ruin this. Jarrah now think that the other housemates were being mean because they knew about them watching them and were trying to get immunity.
And, let's face it, Jarrah aren't bright enough to work out that actually most of the meanness was before they found out.
So it is a total damp squib and they will all laugh about it like Quincy and his pals did in Danny's at the end of each episode.
We could have seen fight night 3!
