Anyone else notice that there were alot of tweets last night on screen about Sarah being pretentious? Getting worked up over a can of beans may have just sealed her fate.
But fair dinkum, do they really believe after seeing the other house that they happen to have, a master chess player, an awesome chef (who happens to be up for nom-noms) and have an insanely awesome artist. It also didn't look as if the housemates had the tools to make a mural of that quality in one day.
Also, hat exactly is this weeks challenge? Is the challenge to catch on that it's all a hoax, or is the challenge to beat the fake hoax. If it's to catch on, most already have, so is it just a matter of going to BB and saying straight out "There is no other house, we refuse to take these challenge?" If the challenge is to beat the other house, well then BB controls what they have to beat, therefore they are in control of the results and whether the housemates pass or fail. It seems to me that the housemates never had a chance of passing this weeks task either way.
