The producers have made sure that there are niggles for the housemates to ensure they may suss her out! If they did not want to work it out they would have put a complete unknown in and they did not. The HMs need to suss her out to get their nice big food rations.
The producers have chosen this week deliberately too because there is a strong possibility that Charley will be the selected housemate to be nominated and her interview is likely to be explosive; send her back to the HMs and OMG what TV joy! Very manipulative Telly but that is what it is all about.
