I don't think Amanda & Kris will totally lose their passports and money -- they'll find it eventually. But I think it will cost them enough time that they wind up getting eliminated for it, leaving Jodi & Christie safe yet again. After all, we don't see them after Salzburg either, although since Linda & Steve were eliminated last leg, they obviously made it to Romania.
Oh, and I'd love to see Nadia Comaneci as the Pit Stop greeter! But most likely, it'll be someone dressed as a gymnast or a gypsy.
