I've been thinking - it looks like the whole house was designed to centre around this task - 2 bedrooms, 3 doors to the diary room (the third one is covered at the moment, usually the other 2 are covered), split dining table, clashing decor on opposite sides of the house, a garden bathroom behind that panel...
It all seems as though this is the climax, if you like, of the twists, and if there are any further twists, they will be very small, probably nomination related. I don't think that there will be m/any secret rooms, and certainly no twist like the House Next Door or the Halfway House.
So I think twist-wise, this is it for this year. Unless they are going all out on this series...
Thoughts?
