[@TheUnknowable] Her powers fluctuate based on the intensity of the emotion the target is feeling, but they change reality (in the Djinn way) in order to resolve the emotions. They're as subtle as possible, and tend to shift the emotions of people around the target in order to shift the situation to resolve the emotions. Amelia usually has tight control over her powers, but when her guard is down (she's overwhelmed, tired, etc) or when the person's emotions are unusually profound, her powers can work without her knowledge or intent.
