Housemate
Housemates were the contestants of the game show Big Brother, residing within the Big Brother House. All the housemates walked out of the house in Big Brother 504, after which a deadlock seal prevented housemates from leaving the house.
By the year 200,000, there were sixty Big Brother houses running perpetually and simultaneously aboard the Game Station; apparently, there had been more houses at some point in the past until the show was forced to "cut back". Everyone on Earth was a potential housemate, the transmat beam picking them at random. Housemates were routinely nominated for eviction, with those who lost the vote being seemingly killed by a disintegrator beam. In reality, the evicted housemates, along with all those who lost aboard the Game Station, were in fact transmatted to the hidden Dalek fleet for processing into Daleks of human origin.
