Homestuck wouldn’t be happening.

Auspisticism is essentially when two people are in a kismesitude but begin to become unhealthy or hostile so a third person steps in taking up a moirail like role towards both parties to pacify them and to make sure that they don’t go too far and potentially kill one another.

Doubt it since the 5x Showdown didn’t happen post-retcon so Karkat never paped him at all.

It was Vriska’s horns, which is probably the logo of Vriskagram

It summarized some of what changed in the retconned timeline
A lot actually. The first 4 acts were fan suggestions via the mspaforums, Calliope and Caliborn are parodies of different types of fans, Trickster Mode wasn’t Hussie’s idea, and all the canon trickster designs minus John’s came from Wecansexy’s fanart, Lil Hal’s human form seen in the recent update was a popular design from the fandom, Caliborn’s OC was based off an old piece of fanart, several of the Beforan trolls are based off of fan archtypes, and so forth.
Hussie knows exactly what kinda stuff is going down in the fandom.
