Guilt
Kay had an inkling that Joseph felt his father wasn't grieving, or that his father was too cold since he didn't show any emotion. What Joseph was unaware, however, was that he felt too much and he didn't want to 'break down' in front of his kids.
Kay sighed as she observed them and remembered what Kyle had said about Stephan.
She wondered how he had ever stayed with such a man. Then again, she stayed because of the kids - and it wasn't like Stephan was a bad man. Just … unfeeling?
No, that was not it.
He was the type that didn't show his emotions openly and always wanted to conform to society's standards.
When Kay was younger and learned more about Country M, she wondered how Kyle could be so open-minded and liberal about his sexuality when he was a woman from Country M. From the stories he used to tell her, Kay could tell how sheltered he had been and how he had to always be the 'right' type of girl.
