LAST EDITED ON 12-17-08 AT 06:50 AM (EST)She did save Bob as he was going home for sure at F4 without her vote. And she did, probably unwittingly, give him an advantage as she told Bob and not Matty her plans. Bob did take advantage and went off to practice his fire starting skills. Whether Matty would have done the same if he knew a tie vote was coming I don't know. As he said he wasn't good at homework. And Bob might have beat him anyway. But at least he would have known he was looking at a tie vote.
Admittedly, Sugar was not a likely winner. But she wasn't that far off from going to F3 with Crystal and Suzie which would have given her a shot, at least if she hadn't gone out of her way to humiliate Randy. Most of the actions that prevented a Sugar/Crystal/Suzie F3 were Sugar's. She saved Matty at F6 when she could have stayed with her alliance and kept Crystal in the game. If so, substitute Crystal for Matty at the next IC, won by Bob. Unlikely to change the result. Then it would have just been a matter of convincing Bob and Suzie to vote off Ken, who had played a more visible strategic game than anyone else left. If Suzie still wins the final IC, the three women would likely have voted off Bob, knowing they couldn't beat him. You would have five members of Onion on the jury. They wouldn't have wanted to vote for Suzie who had broken up their alliance by flipping. Randy (and likely Corinne) would not have voted for Crystal. Possibly Marcus as well. This would leave Sugar close to having four votes.
Course Sugar probably didn't know this. But if she had just been playing to maximize her own chances of winning, rather than trying to bring the survivors she thought were the best people into the final three she might have won. She certainly played a unique game, regardless of her motivations.
