Many (but not all) of these lines were cribbed from Raymond Chandler. It's homage rather than plagiarism because the sixth panel from the end mentions three Chandler titles, and the comic title is a twist on one. That's the difference, you see.

Anyhow, here we have the first major plot change from the movie. If you're familiar with the movie, you can probably guess how much fun I had making it seem like this scene happened in it.
