I don't know why the judges ask them how they feel about coming 5th/6th/7th and then look astonished when they say they are disappointed and disagree that their dish was horrible.
Prue looked quite put out when Steven said he thought his dish was fine yesterday, and said 'well someone's got to lose' rather sharply. 
Having said that I haven't been impressed with Steven's dishes so far, - I like the look of everything Simon has cooked though, so I hope he gets something on the banquet menu.
I wonder if Nathan will be allowed to cook his soggy pastry lemon tart again? - hopefully he's come up with something different!
