Cat appeared to be such a thoughtful and good-natured young woman, yet we learn that she was the one sending Maya the hateful and bullying emails that caused her such pain. It is even more discouraging to realize that Cat was perfectly nice to Maya's face, but that she was saying how much she hates her behind her back. Furthermore, we learn that Cat had engaged in similar behavior before. However, Cat is human and her father had left not only her family with Susie and Luke, but had now also left his second family. Are her angry actions forgivable in light of that, or are her actions unforgivable and even partly to blame for Maya's death?
