When the original party left Florida and entered the Devil's Triangle, it was early summer (June, to be precise) and Scott was dressed in a light shirt and jeans. In this episode, however, he suddenly has a cold-weather jacket that we've never seen before and that he wouldn't have packed for a warm-weather trip.
It seems the group have met a hairdresser on their travels, Liana's hairstyling is different from the previous episode.
