I posted last night on the Official C4 BB Forum that I know Science to be a post-op transexual. The producers seem to be keen to stick to a winning formula. Admittedly this transexual is rather more incredible than Nadia. This nugget of sensitive information was quickly excised from their boards. Only a handful of late-night posters can have seen it. So... They must be planning to use this surprise information as a feature of the show.
