Yeah...then CBS would get sued by the Houseguests because they promised (in the contracts, I would imagine) the houseguests that someone would walk away with the $500,000. CBS doesn't judge the housegeuests at all (except for the producer's pick at the start) and wouldn't take away the grand prize suddenly because the final two were scumbags. They didn't do it when Ivette and Maggie were the final two, and I'd imagine they wouldn't do it if Berika was in the final two.
