I have been having a look at the main area picture, the picture with the crates. The more i look at one of the walls the more i think it can be removed really easily, or could possibly be an automatic door. Maybe a housemate will go do secret tasks and that could be their 'headquarters'. It could be password activated, who knows!?
What do people think??
P.S.
It's just a theory. Can i also just let everyone know, i was right last year about the rich & poor house actually being split, i was right about how it was split too
