Once upon a time, a little ball of light fell from the sky, and from that ball came a little angel named Castiel. He wasn't anything special, just an angel in a tanned trench coat. He was scared and confused, wondering round trying to find a way to make the world a better place, and this little angel had rough nights, sleeping outside and not having as much food as all the other mommies and daddies. But then one day, the little angel met a star, a star so bright it turned the sad little angel into a happy angel. The angel was so happy, that he gave up his angel magic to remain with the star forever, and the angel and the star lived happily ever after together forever.

"I like that story" She yawned, rubbing her sleepy eyes.
"You say that every night after I tell it to you" Dean giggled.
The green burst out from her half shut eyes, her filled cheeks rubbing against the pillow and she tucked herself in.
"Good night daddy" She mumbled, no longer able to fight the strain of staying awake.
He leant in, gently kissing her pale forehead "Goodnight Mary" he whispered.
He flicked the switch to the pink fairy lights lining her bed, watching as her peaceful face became consumed by darkness. He tiptoed across to the door, avoiding the angel dolls and dresses, manoeuvring past the giant pair of angel wings hanging from the door.
"Daddy"
Dean stopped just shy of the door, looking into the black but not really making much out.
"How come the angel has the same name as daddy?"
Dean smiled "You'll find out when your older"
He always loved telling her that story, and one day she'd find out the true meaning of that star.
