Kemal voted for Makosi on the basis that he didn't know what she was up to, or if she was a plant or not and that he knew her the best and still didn't really know her. He voted for Science because he said he was disgusted at Science for stealing Derek's cigar and that stealing should not be allowed in the house.
Craig voted for Eugene because he hasn't anything in common with him and also because he asked Eugene what he thought of him and Eugene told him straight and he didn't like it. He doesn't think Eugene had any right to say anything (even though he asked) as he has only just arrived. He voted for Derek because he thinks Derek is fed up and wants to leave. (think he may have said more than this, but I can't remember)
Anthony voted for Derek because he is a snob and told him to go back to the coal mines and also because he didn't like the way Derek was looking at him when he was eating his Chinese and he voted for Science because he doesn't like his hair.
.... Only joking on Anthony's reason for Science. I just can't remember it.
