Concerning Hope:
I was also wondering if Hope really was Korilla's ordinary sister because Hope neither acts nor is treated as a normal person who is just called "Hope". Of course she isn't in the best mental state but she mostly appears as an embodiment of the concept, down to the reflection about what hell would be without hope. In the scrolls it also sounds as if the House of Hope was really hers to begin with and Raphael just took hold of it. Which is fitting concerning what he does: Toying with the hopes of those eventually indebted to him.
Korilla and Hope also seem to reflect the companion's stories in a way, they all live in some kind of personal hell with a master they can't easily escape and the good versions rarely end in bliss but in the uncertainty and trepidation of freedom and choice - they end with the hope that things will be better, while the darker paths contain the sane certainty of power and control at the cost of freedom and the self.
