Suddenly, a girl appears before them. From her strange dress the pair can just deduce that the girl couldn't possibly be from their time. She begins to speak..."You are quite right. I am from another era. In time, you two will be married, and I will be born from your bloodline many generations hence". The girl's name is Princess Sunday of the Kingdom of Calendar.
