With a name like "Armageddon", you'd expect this upcoming twist to be designed to stir up a huge conflict in the house. I wonder then if "Armageddon" could involve the evicted housemates moving back into the house for four days. Every evicted housemate has a bone to pick with somebody still there - Tamara with Winston and Danielle, Pauline with Jale, Matt and Toya with Helen and her crew. It'd truly be Armageddon if that were to happen - fights guaranteed. Manipulating the house into fighting seems to be the name of the game this year.
My personal theory is that on Friday following the eviction, the lines will open for a public vote. The public will nominate two or three housemates for eviction. On Monday, the lines will close, and the five evicted housemates will move into the house and obtain power over the house for the next four days. Over the four days of Armageddon, they'll make all sorts of decisions designed to stir up trouble, but the most important one will be on the Friday. Over the course of their stay, they will have to come to a unanimous decision and choose which housemate they want to take with them when they leave the house on the Friday. I know something like this would go against so many of the principles of Big Brother, but I think the show stopped caring for those long ago.
One thing is for sure - if it is starting on the monday and goes for four days, it is most certainly going to involve an eviction. I just hope that this twist is actually a good one, because this series truly needs it now. It better not be all hype for nothing.
