Give and Take - Aryan. She had the power, at one TC before the final 4, to give a vote to someone and to either take a vote away or take away immunity.
Final Four Pass - Christy. She had an automatic trip to the final four. However if she missed a set of questions, failed to vote properly or did not do an IC/give me a valid reason why she couldn't do one/did not make a sincere effort, her pass would be revoked.
Show me the votes - Steve. At the final seven, Steve had the power to see who all had votes.
Switcheroo - Jason. At one IC before the final 4, Jason had the power to switch places with anybody.
