The Helen Wood thing was a complete farce, fixed from the very beginning with Pauline 'choosing' (being told/paid to pick her) to go straight to the final. One of the most ridiculous 'twists' in BB history.
Then the viewers were fed highly biased footage of her 'transformation' story which a large amount of them swallowed, hook line and sinker, and did exactly what the producers wanted. I bet they couldn't believe how easily and enthusiastically people fell for it.........even when it was so blatant.
