Although I totally agree with what you say, Oldgit, I do think there could be something in what Josh says about the way Channel 4 changed the eviction rules for the week following Adele's eviction.
I'm pretty sure that, if the housemates had had a choice of who they wanted to evict that week, Jade would definitely have been one of those nominated and I'm also pretty sure that she would have been voted out by the public, whoever she was up against.
Food for thought?
