I can see certain characters going all rambly and philosophical after sex, in a not-quite-aware-he-isn't-making-sense way. But then certain characters read epic Middle German poetry in a fucking basement bar. :) (lol, giving this actual thought: Hegel is not the first thing that comes to mind, but it'd be almost cliche to have Dieter quoting Nietzsche so Hegel'd be more surprising & interesting. Especially if he's still a radical atheist...) On the other hand, if it's HUGO quoting anybody I really don't know where he gets it from. ;)
