Nothing like a good ol'...Oooooo I bet this happens....
What if...
The final power housemate is Helen.....and she chooses the housemates to be with her in the final...
Going on past final weeks one housemate always misses out at the last hurdle...Helen stands up infront of the group on the live show a few days before the final,and she chooses who is evicted.
Sounds far fetched but i wouldn't put it past the producers to bow to her..
