Maybe I'm missing something, but a lot was made of the design of the house being 'Dickensian'/Jack the Ripper etc etc. So far it seems there has been no reference to this in anything the housemates have been asked to do. They're just doing the usual stuff as if they were in an ordinary house. Seems a bit of a missed trick. Last CBB the theme was USA vs UK and that ran throughout, pretty much. This just seems so far like set-dressing.
