You're Sam and Dean's bad ass little sister. Your 18 and Cas is gonna be your lover

A girl in love with Sam Winchester sells her soul to save his life. Later she returns as Crowley's Queen, and chaos reigns as Sam and Dean try to save her.

You are the second best hunter in the world, only second to the infamous Winchester brothers. When your close friend tells you to work a case with them, you comply, wanting to see the moronic hunters up close. But things get complicated when you get injured and have to stay with the Winchesters a little longer. I don't own supernatural or any of the characters.
