Second best? Please back this up.
It's not just the CIT thing. I'll leave shipping out (too messy to voice one's opinion). Courtney suffers from an undeserved superiority complex, and was more of a hindrance than a help to her team. For all her seeming self promotion, I can't really think of a time she was the direct cause of a team win. Let's look at what she did wrong compared to what she did right.
Wrong: did not jump off cliff in first challenge.
Wrong: did not want Harold (who went on to win) to participate in dodgeball
Wrong: continued to allow Tyler (who was just as bad, if not worse than Harold) to participate in dodgeball
Wrong: would not even initially entertain Harold's talent (which went on to win contest)
Wrong: spoke harshly to DJ when he was having trouble facing his fear in the phobia challenge
Wrong: failed to face fear, directly causing the Bass to lose
and the only right I can think of
Right: convinced Duncan to participate in dodgeball
