I keep saying it time and time again but recycle an old twist that works and say its to celebrate 10 years of BB!
My personal choice would be the Bedsit or the Secret Garden, but theres no reason why they can't merge them both AND bring elements of the HND too
Next weeks "evictee" is evicted to the Secret Garden where they are joined by 2 others and they can all observe the house. bring back the phone ... person who answers the phone gets Makosi's role to sneak them in and out, get stuff etc and ultimately decide who stays and goes
Keeps Sree in AND will cause extra fireworks
