Minnie36, I agree with your assessment of "Dave" vs Nathan. In addition, you may also recall prior to the "commercial" episode, in a reward dinner with Sarah, Theresa & Jen, Nathan was playing word games with the younger girls . . . vocalizing how hard it was in Vegas in order to psyche them out re their abilities & adequacies for future competitions (with background voice-overs of him acknowledging that was exactly his purpose in saying these, and Jen saying she saw his game). This action at the dinner which was shown to us in the audience, Nathan's attempted dirty trick in the "commercial" episode, and probably a few things we didn't see but which were reported to Wayne by his "eyes & ears" sidekicks led Wayne to remark, in kicking out Nathan, that "you're playing the angles and not relying on your talent to win this thing." Dave may not have done the most straight-forward thing in Episode 8 USO, but, knowing he may be risking his spot by "butting in" on Joe or Delisco, he sure relied on his talent and gave a great show to those troops!
