 CONT: Robin is wearing a long white dress when they crash. She  changes into floral shorts and a tank shirt when she and Quinn go  looking for fresh water. After he gets the snake out of her pants in  the water, they cut to next scene where they are back to the beach  where the plane is. Robin is looking for fresh clothes in her  suitcase and the shorts and tank shirt she was just wearing (which  had gotten dirty and wet) are in her suitcase folded and clean, and  Robin is changing out of the white dress she had already changed out  of.
