Re: U-Turn photos....
-Nick does wear a white muscle shirt (aka wifebeater) in the first episode during their interview, plus on the photo, it looks like a tattooed arm on the right side of what would be Vicki.
-Brook & Claire both have pink shirts on, sans Claire's denim jacket.
-Nat & Kat are only seen in scrubs, so I don't know how they would handle that unless they use the cast photo from CBS.
-Chad doesn't have a pink shirt on during the first episode interviews, it was a darker blue.
(Yes, I do tape TAR onto dvds
Who U-Turns who....could we all be over-analyzing the event? We know that B/C & N/K do hang out together like BFFs. That leaves the three other teams to possibly buddy-up and/or conspire. J/T dislike C/S, so J/T could commiserate with N/V where N/V would tell them how they dislike B/C, and vice-versa with J/T talking about C/S. (C/S would be odd-man-out since they're probably still on a high from their engagement and not interested in what others are doing.) So both J/T and N/V could make a pact, and possibly form an alliance in Bangladesh(?), to U-Turn their own hated teams by whoever gets there first.

Looks like it could be the one made from Tok Doi (sour yogurt)?? It has the same light color.
I've stepped into your territory, got lost and posted again.
