Cruz was one of the four 2007 'wild card' housemates that was isolated in a room labelled, 'The White Room'. The room was completely white, with white furniture and bedding. The only clothing they were permitted to wear were completely white. The person who stayed inside the White Room for the longest period would become a housemate and enter the house. When a person could not stand to be in the room any longer, they could press a button in the middle of the room and they would rejoin the general population. The button was red, providing the only colour in the room. The people in the White Room were unaware that they were being watched on a big screen by the real housemates albeit with no audio.
