The girl learns to use her powers, and her newfound friend helps her with this. Over time, Ellia realizes that Hal needs change. The young witch misses Ros, but cannot shake the feeling that she is exactly where she should be. Ellia understands that only she can maintain the balance between the mortal and demonic worlds.
