Homestuck builds up from itself; just like the houses in a session are comprised by copying and expanding off of piece of their original buildings. Characters are a well-known way to track this phenomenon. Take John for example. The next character on screen after John is "John's Dead Grandmother" followed by "John's Dad." The other kids' conceptions involve mirroring or inversing specific traits of John as they slowly come into their own forms. Dave is the cool kid to John's dork, except later it turns out both of them are both cool and lame; in different and similar ways. Caliborn is a particularly abstracted version of an evil depiction of John, one who refuses to listen to girls under any circumstances.
This cycle of taking what already exists, transforming it, and releasing the result is also today's topic. On April 13, 2009, John Egbert does not poop. By the narration's own admission he had been eating cake "all day" prior to the webcomic starting, and Rose destroys his toilet before he even enters the session. From there, he's caught up in standard offscreen RPG quests before getting stuck on Scratch duty. He doesn't even realize he's gone almost an entire day without a proper meal when Nannasprite asks him about it. Because his digestive system is already full.
This idea (John having constipation) fuels the course of the comic. The Land of Wind and Shade is plagued by a thick, dark pollution that stains the planet and causes harm in multiple ways. John's personal SBURB quest is a simple one: clear the oil and unclog the natural pathways of LOWAS. This is mirrored by John's encounter(s) with Typheus, the denizen overseeing LOWAS that John is expected to overcome. Typheus's palace threatens to choke John out with the same oil killing the rest of the planet. John's only chance for survival is to, of course, expel the oil, leaving it across the entirety of Homestuck. And then to free the fireflies of LOWAS, he plays the organ. A final symbolic clearing of the pipes.
There's one real criticism of this theory, which is that the classical element of air correlates to the humor of blood instead of yellow bile.
