I rewatched the Big Brother from last night on my tivo and i watched really carefully and kept pausing and slowing it when it went pitchblack and i realized that everytime it went back to the couch that Kathy(the cop from Arkansas) wasnt there and it showed everyone else the entire time...but rite before the lights came back on she was suddenly on the couch...and also rite before the lights went off she want in the livigroom with the others... so i think that Kathy is the Saboteur!!!
