Castiel ran as fast as he could, looking in each room for Anna. When he found her she was playing house with Balthazar. He smiled as he asked to join them. They agreed and decided he would be the daddy. Anna would be the mom and Balthazar, the baby. Castiel was expected to find a job while Anna took care of Balthazar. They built a fort out of blankets and pillows and that was their house. When they tired of that Castiel went off to sit on the clouds and watch the land below.
