Now lets talk about the Aspect of Piss and how it correlates to the Trickster.
Piss in and of itself is a Joke Aspect. It doesn't do anything much from whst we have seen but if we hypothesize its true potential, it might be the reason Trickster Mode exists, and it might help understand a Perfect Run.
Piss is a homophone for peace, which means that this Aspect is quite peaceful. Yet, if we denote what Piss is in real life, then it is a stream of liquid. You know what else is similar to a liquid? That's right. Time. The Aspect of Piss adequately correlates Time to itself, causing a delay or a speed up of an event even unknowingly.
Unfortunately the Gent Class is the perfect counterweight for this Aspect. It delegates the Aspect of Piss to a background role. Causing reality PISSERY happening at the background. At best, comedic moments, at worst... The Red Miles.
Anyways, the Perfect Run happens when someone with the Aspect of Piss goes on a Starring Role from the getgo and not have the Gent Class as that will nullify the whole run.
A Perfect Run that utilizes the everchanging Aspect of Piss to smash the Narrative and ensures everyone, I repeat, EVERYONE gets a happy ending to the point Skaia will turn gold from the amount of reality Pissing that happened.
A Skaia where Black and White lived together as one, and in turn created something new. Something Grey-colored... And might be coated Piss Yellow.
But hey, you may ask what about that part about the Trickster? Well, Trickster, the non-canon reality-warping mode, is actually reality itself trying to fix the mess started with the Aspect of Piss having the Class of Gent. Reality, as a whole, is looking for people who are considered prime candidates that have the capability to do a Perfect Run.
However, that never happened in Homestuck Canon, so Reality gave up and stopped giving out Trickster Modes for the candidates until the Epilogues happened.
If the Skaia run now is completed without being perfect, then the next one might be the one to do so.
