Susannah Goode is excited that Edward Fier is visiting her. She thinks that him coming to see her must mean that he has a way of freeing both herself and her mother. But her dreams are dashed as he turns out to be just the kind of jerk I thought he was.
He asks why she thinks he would want to save her as she has betrayed him. As I said before, he didn't show the ability to realize that his father is a monster. Even when arguing with Benjamin he still had respect for the man. So why would he finally make that connection now? Sure it would be a happy ending, but it takes some time for people to make that kind of change.
