The final 4 will work the same as always. It will be crucial to win POV at that point.
If the HOH wins pov....he can do as he pleases
If one of the nominees wins POV....they can take themselves off the block and the other person that is not on the block and not Hoh will go up in his place.
If the person who is not on the block wins pov....he can keep the nominations the same.
When we get to the final three, the winner of the HOH will get to decide who he wants to take with him to the final two.
When we get to the final two, the winner will be voted on by the jury. The Jury is made up of the final seven evicted HouseGuests.
