About Nick and Vick bump.
I just read online that there wasn't one (Phil didn't mention it on the last Pit Stop either) and it was due to a production mistake on that leg. N & V were wronged in the Piano task and because of that they decided to make it a NEL leg so to be "fair."
I think the rule now is that if you don't check your bag at the Pit Stop you lose it.
Phil can't check a team unless they have paid their cab (Uchenna and Joyce S7) and have all their traveling documents
Side note: Amazing Race LatinAmerica S2, decided to "break rules" and check a team without passports, such a mess that season is.
