Since I opened that can of worms by mentioning Las Vegas, here’s the discovery draft of that scene.  You’ll notice that it’s completely unstructured, starts abruptly, rambles, and then just stops; that’s because it’s a discovery draft.  I know it’s terrible.  I haven’t revised it even once.  This is raw Crusie.  And I may decide to cut the whole thing and write a new breakfast scene (there are a lot of breakfast scenes, six I think) with no proposal, so it’s just a placeholder for now.  But this is what happened while I was writing, and why I researched Las Vegas and then discarded it.
