I disagree. Andrea played it magnificently. Totally threw Malcolm off his game...which got weird. At some point Malcolm should have shrugged his shoulders and just started digging. At worst, others would have begun randomly digging, but he would at least still have a chance and a head start. To just give up on it made no sense.
And I have to hand it to Cochran, he used his advantage perfectly. A lot of people would have waited till further in the challenge to play it, but he understood that the fatigue factor was cumulative. The earlier he made the jump, the less overall fatigue there would be to endure.
Malcom should have given Eddie or Reynold the clue and then gone off and looked elsewhere dragging Andrea along on the wild goose chase while one of the other two went to the original spot and found it.
Andrea is like that pesky little sister who hangs around your room and won't go away and then runs to mom and tattletales. What's interesting is that as much as she hangs around the boys and cuddles with Eddie, they never go to her or trust her as that 4th. She's the Caramoan Matta Hari.
