Michel i agree with all of your points. But I want to change a few things around in the story a little, and through my two sense again.Also sorry for the bad grammar and spelling.
The edit of peter and sarah is to play the poor sympathy for sarah. I get that feeling of what the show is saying. But Yes Peter is Arrogant and useless, he always wants to quit and always checking out Dustin and Kandice. Sarah didn't like the idea to team up either. So this could hurt them in the long run.
Tyler and James, I think they are here for the women 'eye candy' such as dustin and kandice are 'eye candy' for the men. However in the edit, Dustin and Kandice seem to be more competitive than rehabs. I just don't see tyler and james winning maybe final three.
Dustin and Kandice will def make final three. And I dont think there story is over yet. I bet if they can get a lead and they keep it they will win the race. But as you noticed a few episodes ago they had a breakdown, and it shows that the race is hard. But I believe they are showing the true spirit of this race story about it 'being tough'.
Erwin and Goodwin im not sure about them, they have been giving good positive edit all the way through. They don't seem like winners, last season episode would of been okay to put them in there. There just going along, and trying to say in the middle of the pack, but that will hurt them if all the weaker teams are gone. Erwin and Goodwin are also final three, but not winner. I would say Final Four, due to the edit they are given from past season Final Four Teams, such as Merdith and Gretchen, Jeff and David, and Derek and Drew. It could be Final Four Edit.
Lynn and Karyln there story is about accomplish task that they couldn't do before and to show that their not just moms to their kids, that they are also independent women. Im not sure about this team. At first it was a negative edit, then they had postivie edit, and next week it shows them fighting with Dustin adn Kandice. Could this team be another bowling moms team. They are competitive when it comes to other teams!
Rob and Kimberly there story is relationship trouble, its either going to end in a break up or a marraige proposal. That is where I think there story is taking us, it reminds me of Ron and Kelly from seven 7.
Now David and Mary. I think their story has changed. It went from being the nice Kentuckian folks, lvoeable characters that doesn't make it far, now their story is to come in first. I think once they make it into first the next leg will be their elimination leg. As much I as I love them, I don't think they make final three because of the 'race is tough' story being brought up. Especially since David as done 4 out of 5 roadblocks, that is going to hurt them. But if they make Final Three and Win, their story will be told as even weaker teams can handle the tough and stress of this race.
