Summary: For prompt #3: Sam is slowly becoming an angel (likely due to trying to switch demon blood with angel blood in order to redeem himself somehow or simply to detox from demon blood and it goes too far), and while his wings are small and weak (too small to really fly with), Cas is fascinated with them. He likes to groom them, explain to Sam what is happening in their development, and help him through the aches and pains of what seems to be the equivalent of angel puberty.
