Melody thought about that. She needed the death energies to heal herself. She didn't really want to kill somebody... but...
"I can heal. I don't know how much yet, but I think a lot. Do you think you can arrange to find some terminal patient to bring along just in case?" Pushing somebody over the edge would provide her with enough energy to heal herself. She would just have to control herself until it was needed. But maybe that would help her fight her addiction, as well.
When did she want to test it? "Soon." She answered. "As soon as it can be set up."
