Many people leave their stuff on beach chairs, go back to their room, etc. So, seeing someone in a shirt on one video, then without a shirt in another video, is not strange. It is a beach resort. I have seen countless times someone leaving stuff on their beach chair and asking someone to keep an eye on it. Not the smartest thing but it happens all the time. People get up before the break of dawn put stuff on a beach chair to "save it" and go back to their room, go eat, etc. This is resort behavior, not strange at all.
