I think the blue lady is related to her grandpa’s death, after all she said once for a long time she thought it was the blue doll that shot him. The demon that eats the universe made me think of a black hole and how that’s related to the conversation she had with doomed calliope on how space players become a sort of void that collapses on itself?? The clone makes me think of the time she was mind controled and turned evil, idk about the rest.
