For a twist, 2 of the original housemates should be told they're being evicted. They're not put in any house next door. They're not put in any room under the floor.
They're kept behind the door they left from. Big Brother provides viewing of the house...and food etc...right behind the door where they were 'evicted'.
Then at the following night the housemates are told one of them is evicted...when they go to open the door on their own...they see the 2 other housemates...sat there...their mission is to hide them for the rest of the night in the house..without anyone else finding them...if they succeed this than Big Brother will reward them with a triple shopping budget.
