Which Total Drama Contestant fumbled the hardest???

Simply just name a contestant from any season who had everything they needed for a easy win, yet still screwed up and lost.

My vote goes to Scarlett from PI, she had a free trip to the final 5 with a loyal alliance member when the other 4 contestants were mostly independent (aside from Shasmine). If her and Max convinced Sugar to vote off Sky or Jasmine, she would have gotten rid of the biggest physical threats and could make it to the final 2.
