It's speculated that John & Jessica are the team to be eliminated this leg, and due to our future sightings of other teams, they probably are. What puzzles me is HOW?! They are physically and mentally one of the strongest teams left, not to mention they have an Express Pass! Here's my theory: they play the EP on the Detour, but they're screwed over by the Roadblock.
Judging by the 'looks' of our Detour, neither option seems difficult enough for John & Jessica not to complete. Then I saw this:
“I Love Monkeys!”– another Team makes history while trying to avoid elimination
This 'hint' from the episode preview is probably the reason why John & Jessica get eliminated. But the question is, HOW?! From the previews it seems as though Caroline struggles terribly with the Roadblock. Possibly, she takes a 4 hour penalty and they survive because Jessica takes so long? I have no idea. I guess we'll have to wait and see
