The wheel will decide who is on which of the three cliques. Three cliques of five. The last person standing on the wheel is HoH for the first week; everyone must throw to that person.
You may not nominate anyone in your own clique. After the fifth eviction, the cliques twist in. The first five will battle it out to return to the game.
Once that happens, everyone re-enters and the Roulette Twist is implemented into the game.
