I think Blake is one of the most interesting cases in this cast, simply because you could classify him as both a hero and a villain. Even when Jenna/Hunter/Jarrett were attacking Blake in season two, he somehow stayed afloat to the final five from the bottom. On the other hand, he was very vocal when he felt upset about something involving the game or someone being dishonest, and he made sure everyone know about it.
Coming into Survivor Five: Heroes vs Villains, I hope Blake realizes how much tougher the competition is going to be compared to his season. If he can manipulate the others, and be on the right side of the numbers at merge, I wouldn't be shocked if Blake goes deep into this game.
