The threadmaker has made fair points. I've never been to an eviction or on bbbm but I have been inside the house before and I entered through the back. Everyone who came thereafter came the same way and I assume we all left the same route; through the camera run linked to what we now know as the diary room. The back of the house and back of the whole elstree compound is the least conspicuous area of the whole plot, I thought. If they are delivering furnishings, top secret bits and bobs then it is completely plausible that they would have done it this way!

This of course is all speculative but there is a logical thought process behind it so you never know!
