There were rumors that the jury suspected it BUT it was the jury's fault George hung around so long.
FINAL 10; Nina and Shaun made a HUGE blunder in waiting to show their idols until after the votes were cast. They should have definitely flashed their idols BEFORE anyone voted and caused the Vigilantes to completely panic and scramble. Don't tell them who the idols will be played for OR if they will even be played. Then, if they are afraid that George will put his own idol, they could reduce the risk and vote out, say, either Gerry or Matt. Amateur Survivor by waiting to show your idols to a power group.
FINAL 9: In the final 9 as soon as the plan was Shonee, Nina should have told Shaun and Shaun could have flipped Simon. Nina could have told Shonee and Liz and hoped they heeded her advice that Shonee was the target and to flip it on George. (that's how they've done it here). At least it would have been 3 votes for George and Liz could know she could trust Nina.
FINAL 8: If the final 9 plan did not work, and it was known that George, Gerry. Matt, and Hayley were splitting votes, this would have been a GREAT opportunity to get rid of George. Nina, Liz, Shaun, and Simon could have voted for him.
FINAL 7: So, if neither of the above plans worked, then it could easily have been Nina, Liz, Simon, Shaun, and Hayley to vote out George. Once the plan became Hayley, that was the ripe opportunity to cut off George.
After final 7, things were extremely difficult. However, EVERYONE should have known VERY early that the power 3 was George, Gerry, and Matt. Once Shonee was gone, it was cemented and GGM were in the minority.
