A simple song for a not quit simple love

simple song for a not quit simple love
An angel and a human, what could be easier?
simple song for a not quite simple love
The only thing he left you was his coat and a broken heart

He once saved you from hell, for that you gave him strength to rebel
He would rather stay on earth but no he did not, unfortunately he felt like god
"I'm sorry Dean, I can't hold them back. Run for your life." Then he was dead.
And a Leviathan was left.

7x17 for all of those who like to hope
7x17 for a broken heart and his coat
7x17 for a not quit simple love
7x17 for the rebel, for Castiel
