The original message states...Sugar did more to decide the final five than anyone else...
... and while I agree that she did have the most influence during the end game, she was not playing the game.
For the few episodes Ace had her back, and appeared to be directing her decisions. Then Kenny manipulated her into voting off Ace... again she was not doing her own thinking. She then was able to float as others played out the drama. She was never in danger because the antics of others, whose performance got them a seat on the jury.
When she sided with Matty and Susie, over Kenny and Crystal, it was because of her idea of 'what is fair' more than it was game-playing. She didn't like the way that Crystal was 'bullying' Matty. The same thing happened at F4 ... her season was often about her recently passed father, and Bob was a father figure ... again she was not playing the game, but coming from her idea of 'fairness'.
I agree with Michel that Sugar was a fake ... just an actor. The emotions of her father were probably real enough, but there were likely times the act was overdone. I can understand where Corrine and Randy are coming from ... and for me, they are far more memorable than Sugar. I found Sugar annoying.
The only thing Sugar seemed to contribute was when she told Matty to vote for Crystal ... but then Matty is not an intelligent player. Jiffy had to tell him to settle down or he was going to lose that first endurance challenge against Bob. And he wouldn't listen to Randy when Randy tried to tell him the fool-proof way to win the 'sling-shot' challenge.
Wait a minute, who were we talking about again ??? Someone quite forgettable I guess.
