Bijou wins!
@FatElvis: if you're the lucky guy to cast the last vote in a challenge that is lost, you can select a girl already on the ladder to challenge the girls above her.
Now it's Bijou vs Kathy Moore, which is very difficult for me.
In the end I vote Kathy with a slight margin because of her figure/legs/bum.
Bijou 0
Kathy Moore 1
