"Well, he did kind of have a point" is such a fitting line for Crowley to fall on. And I like that he thinks "it's beautiful" and that he always remembers the burn, because that feels very Crowley. The latter bit makes me feel like I could see how a fairly decent guy could work for evil, aside from it being due to just being a demon.

I came here via a link at fic_promptly, in case you're wondering.
