Head of Household: Each rotation, 1 person wins HOH and nominates 2 people for eviction. If the POV holder uses it on the nominees, they have to pick a replacement nominee. At evictions, If it's a tie then the HOH casts the sole vote.
POV: Power of Veto, or POV, is a competition that is held each rotation after nominations are held. This competition gives one housemate the chance to change the nominees. The HOH will replace any nominee taken off the block.
The Saboteur: A secret houseguest that would sabotage the house in order to win money instead of win the game.
