As you've revised this paper, you've added to the character portraits of the limo guy and Marty, with the former being flattered that the latter admired his skill with language (that was what the "interlude" echo was about). The limo guy is likely better educated than Marty, which is why Marty let's the driver step in to explain things. As Marty said, he doesn't want to be considered a punk. 

So you have a short story now that could the first chapter of something longer if you write the funeral scene and then, for example, the limo guy learns that Marty has left his fortune to him, the new "godfather." The limo guy decides to retain all four Paul Bears and builds a crime empire...just cut me in on the movie rights. Jackson
