This particular Survivor had more mystery leave outs than I can ever remember. At every tribal there seemed to be something that didn't quite jell and left me wondering why it happened.
I think one of the other mysteries was KB's elimination. I believe in an interview Brenda said that the plan was always to vote her off because Kelly was paranoid and they were afraid that she'd join back up with Alina at the merge. However, they split the votes to try to get Marty to play his idol at the same time to accomplish two things at once. Marty didn't take the bait, obviously.

atllover, Natalie's strategy WAS to play nice while letting Russell do the dirty work. She got in good with the Galu girls so that she wouldn't have been eliminated for a long time if Foa Foa's coup had failed, and her working on the women also led them to vote out Erik, which turned the game around for Foa Foa.
One of the most interesting scenes of Samoa in hindsight was in the episode when Liz got voted off - Russell was debating the benefits of taking Liz or Natalie, and he praised Natalie's social game as something Foa Foa would need to infiltrate Galu. He was right in that regard. In not so many words, he was basically saying that he was bringing Natalie because she was the better player. Which makes it really hilarious when the same traits that Russell was praising became the reasons he lost to her.
Anyway, Natalie and Jud both played passive games, but I think what frustrates me about Jud winning is that he was always in the dark when it came to voting. Natalie, Russell, Mick and Jaison basically controlled every vote in their season, so Natalie didn't have that same feeling of stumbling into her win that Jud did. Sandra was also usually in on what happened at Tribal Councils too, which is why she had to flip back to the Villains when Candice switched on the Heroes.
Natalie and Sandra also each had a key move that they pulled off to enable their win down the line - Natalie got Laura's girls to turn on Erik, and Sandra got Russell to turn on Coach. The thing that probably enabled Jud to win was Na'onka and Kelly quitting, and that wasn't something in his control at all.

And yeah, I agree with Pepper if Na'onka really did vote for Jud. I haven't seen the voted revealed officially but Wiki is saying that Jane, Hoho, Brenda and Alina were Chase's votes and the others were Jud's.
