Jacqui will have David going for her now, while the others say they didn't know and voted for the alliance. I thought Jacqui was voting on emotion more than anything and allowing the others not to get blood on their hands while she did made it look like she didn't care about the game. While Zack was a number for David it's also true that, as much as I like her, Shonee she is a far bigger threat for immunity than Zack and according to the edit has an amazing social game. Sharn really annoys me so I hope she doesn't benefit.
The twist seems to have shaken some things up which isn't bad in itself, but it also felt like they were making it up as they went along, which inevitably will make people wonder if it was done fairly.. In this episode for instance the first challenge saved 2, but the second only saved 1.
