GOT IT!  

THEORY ONE - 
The anticipated 'Olympic Themed Task' is the detour for this leg. 
1. Swimming 
2. ?? Athletics?
J/K get u-turned by T/V because they think it was really rude to laugh at Luke. They do 
other one but are forced to do swimming one because they are u-turned. 
THEORY TWO - 
T/V take fast forward. Explains absence from preview. Swimming is a misc. task?? 
THEORY THREE - 
T/V are super behind or ahead. Either they or J/C u-turn K/J. 
P.S. I HOPE K/J GET ELIMINATED. THEY ARE SO RUDE AND INSENSITIVE. AS MARGIE SAID THEY
ARE BLACK AND KNOW HOW IT SHOULD FEELS TO BE LAUGHED AT ETC.
