First of all, calm down, I'm just giving you my opinion. Secondly, even if they are cartoons, if they decide the winner, it could still be Gwen or Owen, because it's like you said and I quote...
"Well, here's my stastistics...
Gwen: She has 75% of winning.
Trent: 60%
Bridgette: 55%
Geoff: 55%
Lindsay: 45%
Duncan: 45%
LeShawna: 40%
DJ: 30%
Owen: 25%.
Since, izzy and Eva return...
Eva 5%
Izzy = 35%"
So, if Owen doesn't win, it could be Gwen. And I'm not sure who said it, but Gwen is popular with the audience, the fans and maybe even the campers.
