Yes, I never thought I'd see someone do worse at Final TC than Amanda, but Sugar topped her.I think she was right to give Corinne the finger, because Corrinne really went too far (and I'm a Corinne fan). But she certainly badly messed up with Crystal, Matty, even Randy and Charlie.
She did seem to be helping Bob to win, and that seemed to be her intent. By going with a final Bob/Matty alliance instead of Crystal/Kenny, she seemed to set herself up to lose. But I almost cried during the final 4 TC, it was very moving.
She controlled nearly the entire game, including controlling who won. Unfortunately, her issues prevented her from giving herself the win, which I think she totally could have done.
She was the most memorable player. Bob wasn't that deserving a winner, but it is an interesting reflection of different seasons. Way back in season 1, the manipulative Rich defeated his alliance mate, challenge-whore Kelly. This time the manipulative Sugar saved and gave the win to her alliance mate, challenge-whore Bob (a nice guy but not exactly entertaining).
