Her once overwhelming attachment to her son is now replaced with bitter resentment. Now that Sei has broken from her grasp, she now views him like everyone else. Before it was just the two of them, now it's just her. This makes me unbelievably scared for Sei. She hates everyone else and even went as far as an attempt at murder. Think of what she will do to Sei, now that their link has been severed scares me considering how much damage she's done to him when she still "loved" him.
