Oh, I don't know, really. I'm sure that if we did see it, it would be wonderfully written and acted and be meaningful in the story and I'd be perfectly happy with it. Because Gaiman wouldn't even write it if he couldn't make that happen. But in the absence of that reality, I do just sort of wonder if it might be more effective to leave it to the imagination. Especially because it seems like a case where it would be extra tricky to make it work, tonally; neither sticking jokes in such a scene nor serving it up as a pure, unadulterated angstfest feels appealing when I try to imagine it in the show.

Then again, maybe I've just read one too many fics in which Crowley is basically like, "I don't want to talk about that too much, it's ancient history, it doesn't define me, and I don't appreciate people being morbidly curious about what it was like," to the point where my instinctive impulse is to want to back off and give him privacy on the subject. :)
