Oh, for sure. Sadism, low empathy, a tendency to stir the pot and experiment with their conversational partners, a detachment from humanity and fundamental belief that they themselves are not human...Isabelle takes after her father in many ways. These negative traits are tempered by her capacity for compassion and her sub-zero self esteem, but they're still very much present and occasionally destructive. More benignly, both of them are very moved by the arts, especially by music. They both also have strange senses of humor and are kinda oddballs.
