I could have told you Jon would be staying, and if I'd still been in the bookie business I'd have made a packet!
Jon is incredibly boring, the other housemates fall asleep while he's talking for goodness sake, so you would naturally assume that they would nominate him for eviction.
But you're forgetting the fact that he's also going into the diary room constantly, and he's driving Big Brother CRAZY!!!!!
What better reason to keep him in! It is so funny watching him, I almost think he's doing it on purpose!
