There's seasons and episodes missing!?
There are. Behind Big Brother began recapping the show in 2003 and since then we've lived through server crashes, legal threat shutdowns and all sorts of disruptions. As a result there are gaps in our recap archive.
We're slowly filling those gaps in, but we're looking for fans to help us. If you have a knack for writing down what you see and can cover episodes we're missing, please get in touch!
