To look at him, no one, especially not you, would have guessed that he was an angel. The rather small frame, the rumpled trench coat and loosened tie, the stubble and the messy hair definitely did not fit the human view of angels. But then, did any of them? All the smarmy, back-stabbing dicks-with-wings that showed up at random intervals to give you stomach cancer and destroy towns really didn't fit the bill, either.
Well, Claire Novak might have passed for an angel. That is, if Cas hadn't fried two demons and ripped through her bindings within the first three minutes of having her as a vessel. But Jimmy's body? No, there was very little on the surface that would give a clue as to what was inside him.
If you looked deeper, though, if you really looked at those stunning blue eyes, you saw something more. Something that wasn't just human. Something that was lovely and almost frightening in its intensity. It flashed with the emotion he wasn't supposed to have. After a while, it comforted you to see it there—and you would fight to keep it there, to keep those eyes from going dull and human. Because no matter what Anna said, it was that indescribable something that branded Castiel as an angel; that made him who he was. To be anything less, he wouldn't be the same person you had come to love.
A/N This is the first thing I have ever written for Supernatural. I think it's a little choppy because I started out in full third person but later switched to second, but I did my best to polish it when I typed it up. Let me know what you think!
