Scarlett

Scarlett is a highly intelligent individual, with a shy yet enigmatic behavior. She has been shown to be very crafty, and can easily manipulate other people with her superior brain power. This is best displayed by her relationship with Max, whom she uses to carry out various "evil" deeds which she would not normally do herself. Although she has an initially polite exterior, she also has an evil side that she keeps well hidden from the other contestants. Scarlett reveals her true nature in Scarlett Fever, as she threatens to destroy the island and kill the other contestants multiple times in order to retrieve the million dollar prize.
