Fulke is the clearest expression of Valhalla's religious argument. She is not cynical. She genuinely believes. And her belief has metastasized into something that can justify anything, including what she does to Sigurd. The comfort her faith provides has been purchased by others at a cost she does not have to pay.

Sigurd loses an arm in this session. The vision Valka gave Eivor at the beginning comes true. Prophecy in Valhalla is not a mystery to be solved. It is a preparation for something you cannot prevent.
