The show Reality chat on TV Guide Channel last night aired new interviews with the houseguests. However, they didn't just show the fourteen that everyone knows about, they showed someone who we had never seen before named Samantha. All of them are wearing the same clothes as in the Early Show interviews, the official pictures, and in the commercials. So could she be America's house guest or did she drop out. That would also not make sense though because there were only fourteen pictures in the memory wall and fourteen places at the table. I think it would take a while to change the memory wall, so they would just throw another person in there. Here is the video.
