No fear
There was another theory that arose that stated that the Maiden was not actually afraid at all. She was able to overcome her death which was approaching soon somehow. The way that they determined this was by examining her hair and finding specific hormones in it. Amazing what scientists can tell us.
Inside the hair, evidence from those hormones supported the claim that the mummy was able to deal with and come to terms with her sacrifice. So maybe she was fully aware and believed it was an honor to be killed for the gods? Or perhaps she just accepted her fate and stopped trying to fight it.
