Mary was first. The flames erupted as she checked on her babe, shock crisp and clear on her features as the fire danced around her body. Her blood fell onto her babe's little forehead. She left behind two sons and a vengeful husband, so it goes.

Second came John. He felt his son's life came before his own so he sold his soul to a yellow eyed monster to keep his son's heart beating. He didn't even get ten years, so it goes.

Ellen and her daughter Jo came and went, a mother not wanting to leave her little girl to die alone. Or face a life without her. So it goes.

Sam and Dean themselves died alternately, always finding their way back to each other and their friends. So it goes.

Castiel went his fair share of times, leaving the green eyed hunter in a state of denial and distress. He thought he had lost the angel forever, so it goes.

Bobby left them, too. Even the greatest fathers can't stay forever, so it goes.

Only three of these people die and come again, returning to each other as if Death never knocked on their door. But the deaths most distressing were the ones of Castiel and Dean. They left each other and came back again, eyes wide and full of faith and hope. No man, not even God himself, can keep them from each other. It's just not the way of the universe.

Of course, Dean loved Sammy with a fire but not as he loved Castiel. He loved his little brother so, but Castiel was something different. Something new. He wasn't just a friend or family. Castiel was a best friend and a lover. He was the man who hung the moon and the man who could tear it down just as easily.
