Well, one of Her primary mysteries is that She remained in the cave with Loki holding a bowl over His face to protect Him and capture the poison dripping from a virulent snake that Skadhi had positioned above Him. Think about that. Think about how heavy that bowl would become and how quickly. Think about the pain of having the venom splash onto one’s hands. Think about how hungry one might be or thirsty and yet be unable to take a break without bringing agony to a loved one. Think about the need to endure with no end in sight. It’s one thing for an ordeal worker to go into a planned ordeal. We know that no matter how difficult or challenging or painful the ordeal might be, it has an end. It’s going to end and we’ll be taken up and fed and warmed up and cared for and brought back to normal head and heart space. Sigyn had no such surety in the cave. This was an ordeal with no end in sight. This was an ordeal with two choices: give up and leave or endure. She chose not to abandon Her family. She endured.
