Prompt: "How can you think about letting a human violate you like that?"

Uriel refused to look at Castiel, at the human mudmonkey that he wore. These forms they had been ordered to take were weakening Castiel's resistance to temptation. Uriel could see it, wafting around him like demonsmoke.

I do not understand, brother, he said, refusing to use his mudmonkey's impure voice.

Nor do I, Castiel murmured. "But Uriel, I feel—"

Do not, Uriel interrupted, dare to use that profane thing's vocal cords. Speak as what we are—the greatest, most powerful of His creations.

Castiel bowed his head, taking a breath that was unnecessarily deep. I feel… I do not… He turned, trying to meet Uriel's gaze, but Uriel looked past him. Please, Uriel, he said. Tell me what to do.

Stay away from the human unless ordered to be in his presence, Uriel commanded. Deliver messages and leave. Do not linger, and do not touch him. He strode to Castiel and let his mudmonkey's natural size lend weight to his words. Do not let him touch you, Castiel.

Castiel nodded, lowering his gaze. As you say, Uriel.

Uriel backed away, closing his eyes and listening to Heaven's Voice. He tried to ignore the wrath and envy swirling in him—they were sins. He was God's perfect soldier, the Angel of the Sun. To let a flawed, blasphemous mudmonkey—Alistair's favorite, brother of Azazel's chosen—cause him to feel…

He glanced at Castiel out of the corner of his mudmonkey's eyes, and he let his angelic sight show him Castiel's true form.

Glorious. Heaven's own light. Too magnificent for a mudmonkey to ever truly comprehend.

How can you think about letting a human violate you like that, he wondered, and never see me?

No matter, though. Soon, Dean would die and Castiel would join Uriel, as they should done millennia ago when the MorningStar first offered them the chance.
