The HOH room must be locked because Rachel has been getting ready downstairs. Plus when I first looked in around 9:30 she and Jordan were asleep there. Then they were in the have not room...detective work says they were kicked out.
They are setting up Pandora's Box is my best guess and everyone is anticipating a visitor or luxury. However, Rachel told Jordan in the have not room that she wouldn't open it...so...why are they all running around?
