I don't get why people thinking David saying who are playing the game the hardest was this big bad thing. I think it was a very smart move. In a house where you only have time you stew on things people have said, lets see if the others are smart enough to pick up what he is putting down.
What he said about Priya was dead on the money, she is suddenly best friends with Skye as soon as she had the power - so be pointing that out inside the house might put doubt in Skye, Cat (who have both had the power) and Aisha's mind about her 'friendship' with them. And on the outside world - Skye's minions that might be voting for Priya because of how nice she is to Skye might think twice about doing so. So disappointing in the type of player Priya has been. Thought she would be outspoken and strong but really is just being fake and frickle.
And as for Jason, seriously the guy has no spine. Goes on about how he is so disapproving of Lawson and Cat, had the perfect time to say something to their face but didn't because having an opinion or stance on something in this house draws noms points. Spineless. Totally proved tonight what David said again so on the money.
He wasn't only doing it to get a reaction out of the housemates, he was doing so the public would start over analysing everything they do. He has probably figured out on some level that outside the house he is not been seen the way the housemates are seeing him, if he has been talking strat the whole time, he might be thinking 'well its worked to get me votes so far - I'm going to step it up.' He has resigned that fact he wont win but he isn't going to make it easy for people like Priya and Jason to cruise their way in by not showing any character.
