The conjurer

"There are more ways than one of living eternally." This statement of Foe's (told to Susan) following the narration of two tales of two different women is meant to comfort and inspire her. He is asking her to think beyond her present abject conditions, to look at "the big picture". He tells her that her vision and her story are not dull, but that her story "is too much the same". Does he mean that she has not learned from her experiences, that she has not shed "the husk" of her old self, not metamorphosized? Is he waiting for her to evolve a little more?
