Over the past few weeks, Cathy has started to speak publicly about mental illness. She wants people to understand the struggle that families and their loved ones who are ill go through.

Recently, Christian told the priest that Mark would probably be at his next court date. Mark has super powers that protect him from knives. And Mark would probably have Christian interrogated by the FBI.

But the more of their story she tells, the more she worries her family will be misunderstood, that Christian's life will be misunderstood.

"The most important thing to me is that the story says — A: Christian truly is sick, he's not evil. He's really sick and has been for a long time, and, B: His dad loved him so much as he did all of us, and his No. 1 goal was to try help his son have a normal life and to be happy," Cathy said in a recent interview. "He wanted his son to be happy and feel loved and cared for by us and others."

Cathy struggles with the will to forgive Christian versus how angry she feels. But she can't ignore how hard Mark worked to try to save his son, and she knows she has to continue on that path. She knows that's what Mark would have wanted.

"I have to have a spirit of forgiveness as much for myself as for Christian, or it'll destroy me," Cathy said in a recent interview. "I know that. I know that harboring hate and harboring anger is just destructive. There's nothing good that can ever come from it… They say love is an act of will, and it truly is."
