I don't buy the whole 'Jade is really thick' stuff. I think she is playing a clever game here. The stuff she has come out with since being in the house has been unbelievable. No matter how uneducated or dim someone is, there are basic things that you know. Her comments seem too stupid. I think she is trying to be the 'Helen' of the series. The differnce is that Helen's comments last year weren't overly stupid - she usually has some logic behind it eg, Chick peas being made from Chickens'
In my opinion, Jade is over acting the dumb bit. She is doing this so that the housemates think she isn't capable of having a game plan. She then will suck up to everyone in the house and act the innocent baby. When she's alone with various people she then bitches about the others.
The effect - well she aviods nomination, the housemates think that she is a bit thick and have her on their side.
This week, she's been caught out and people are beginning to suspect her. So, she now plays the innocent trick again, does more cuddles etc and stresses how she ALWAYS tells people what she thinks of them..........yes, Jade - of course you do!
