Yep... Jonathan and Ana didnt needed to paint such a target on themselves so early, against some strong teams. But thats part of the game, no rule about who you should use it. Their major mistake, that might bite than in the ass later, the combination of using the express pass (Jesus, save for when you are in dangerous, only use for 1st place when you still have it in the last leg you can use it). Made even worse they taking the lighter weigth for themselves and not making the task. At least they admitted they didnt put the right thought about it.
Now, it seems Scott and Lori also painted a targed on their back aswell by trying to come off as weak to the other teams and doing so well. They all noticed it. Also, they getting so hot headed with other teams using something against them and even between themselves during the detour, might be a sign of some crack at how they try to show to be calm, cool and collected.
