All of a sudden, the white woman is wearing men's clothing. None of the men had packs with changes of clothing, and none as short or petite as her were shown previously. From where did they come? Also, a woman would not have worn men's clothing back then (she had just spent three days roaming the forest dressed in her frock---why couldn't she have continued now that she had protection and an easier time going?). There was also no explanation of why the two were out alone after the nighttime scene.
