There were a number of things to address in the responses she got from Taweret, but there was only one thing she could think to ask. And as the Egyptian goddess said she was fine with blunt speaking, Sigyn simply asked, "Would it be rude of me to ask what form you do take for your work?"
She'd seen a number of Egyptians in their animal forms, or with the head of the animal that represented them. But for people to think Taweret was a demon, it had to be something rather spectacular. And curiosity was pushing at Sigyn's mind, so she asked.
Of course, there was always the chance that Taweret would tell her to take a flying leap for saying something. That was blunt speaking as well.
