On the next “Big Brother” Season 15 Episode 21 “Veto Competition #8,” the contestant numbers are dwindling and paranoia in the house is so thick you can cut it with a knife. The old saying, “If you can beat ’em, join ’em” never made more sense than now, as the contestants can’t hide their alliances any longer. Now the heat is on. Andy proclaims he is in a good position, and Helen states she is on to all who are shady. Loyalty is questioned when sides are chosen, but nobody wants to become the next target as contestants hop on the crazy train.
