Kassy can now control peoples thought, emotions and actions. She is using her newfound powers on her poor clients. She makes their lifes better, or at least she thinks she does that, but she has complete disregard for what they want. She decides whether they should break up with their significan other or not, should they keep seeing (and paying) her or not. She is not selfless but also not completely evil either. She has a hard time controlling herself and not use her control for just pure mindless fun. She is a chaotic character, who is still looking to find where she stands morally.
She amkes her see things, terrible, horrible visions and makes her associate them with her relationship. She makes her cling to her, and make her unable to make decisions unless she consults with her. But she also helps her leave her toxic boyfriend and encourages her to move foreward with her life which she struggled with for years now.
Life is not black and white. Our decisions are not either.
What would you do if you were in control of someone else completely? Would you be good or bad? Maybe inbetween just as Kassy?
