It's only the first week of Big Brother 11 but already the twists and turns have begun. Earlier this week, the housemates nominated for eviction by their fellow contestants were Shabby, Sunshine and Dave. The trio took part in a task, however, and the winner got to put someone up in their place. Dave won and chose Rachael to replace him. These are now the three housemates we can vote out, so tell me: who should leave?
