She is a trained psychologist, and she uses classical conditioning to either help or hurt. She feeds off fear, and she is sickly sweet. If she respects you, she will use classical cnditioning for good. If she hates you or disrespects you or thinks you're weak, she'll use it to hurt you, make you fear things or make existing fears worse. She can be genuinely gentle, but it is very rare. She loves doing experiments on humans, whether unethical or ethical. She will use it on you for anything.
