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.
Well, I would argue that it did make a difference. Had Malcolm found it he would not have had to bluff AND he could have possibly saved his buddy if he played it right. Many things could have happened.
I do agree with the part that he should have tipped off his buddies and played decoy to Andrea.
And, I must say, Andrea can hang around my room any time she wants.
