Either Toya or Matthew will be joining the rest of the long list of housemates up for eviction. But Big Brother needs to throw a nasty spanner in the works. After the choice has been made, that housemate as the power housemate, should be given a choice to save themselves by taking Helen's free pass to the final. If they decline they face the public vote along with the rest of the nominated housemates. Or, if they accept, they save themselves from this week's eviction and Helen loses her free pass and is eligible to be nominated for future evictions. Now is the perfect time to do so, because it could cause WW3 in the house.
