We Know Castiel Is Based On Cassiel The Archangel But My Favorite Little Headcanon Is That He Was The

We know Castiel is based on Cassiel the archangel but my favorite little headcanon is that he was the archangel Cassiel.

He was created as the angel of Saturday, patron of the vulernable and the overlooked, the angel of tears, angel of temperance.

But that was it, wasn't it? Castiel lacked temperance -- He could never be like the other angels, God hadn't created him to be a warrior like his brothers; Cassiel was a gift to humans, the angel of strife and duality, something so fundamental to humanity. The only angel who could really understand them. The angel who sat and watched, waiting to be called upon to deliver peace. Cassiel was God's love for humanity. How could God not know Cassiel would get too close, too involved with humankind? Maybe he did, but he could never know his own love would ever defy him. Maybe he could never know that whatever he burned with his divine love was also scorched with his divine wrath, enough of it to break ranks when he finally tired of watching Heaven play with the Earth.

So God punished him, bent him into the shape of a solider and named him the shield of God as a reminder of what his role had always been. But Cassiel was special, he would always be special, so he disguised Cas, protecting him from the persecution of the other angels. Maybe he even wipes it all from Cas' mind, gets rid of the memory of rebellion before Cas can hurt himself with it again.

And Castiel does it right this time. He stays just as detached as he needs to be, he protects only who he needs to protect, he does only what he is told to do. So God gives him another chance, another opportunity to prove himself with something big, the perfect task for his angel of the vulnerable.

Go fetch Dean Winchester.
