This strip works a lot better if you ignore all the material that follows.  Like, I wasn’t expecting there to be More after this.  But as we’ll soon see, Joyce and Walky settle down as normal college students again and try to get teaching degrees.  It’s weird enough that they’re basically World Saviors following this, without also throwing in “Walky wrote credibly about the goddamned afterlife,” that they can pass through the rest of their existence being essentially unremarkable.  Being normal makes for better stories for them, though, rather than them being unmistakably famous, so whatcha gonna do.
