Jonah, a former VMR contestant, has proven to become a powerful player through his experience with group games. His social game, as well as his ability to win live comps, may result in him making quite the dent on this cast.
You'll never meet someone that comes across more genuine than Jonah, but don't be fooled if he's doing it for the game. I expect Jonah to do well on season four, but it's going to take a lot of maneuvering to get there.
