It’s weird reading about John getting surrounded by green fire, hearing Vriska talk about how these challenge will make him a hero, and gathering that a part of John feels that insurmountable danger of is exactly what his life needs. The prototyping of Bec illustrates this; it was a conscious choice for Vriska, but putting John to sleep to instate it indicates a subconscious choice for John. The pattern repeats much later when John goes to fight Caliborn.
There’s also this line (4875):
Which refers to one of Grandpa Harley’s BEAUTIES, a cipher for his necrophilia. So through a minor gag about Vriska’s vanity, we are told that John is obsessed with death. This was first hinted in Act 1 as John was looking at his movie posters: “Films about impending apocalypse fascinate you.” (1921) If Homestuck is still operating in Freudian terms here, the suggestion would be is that Vriska is operating here as a manifestation of John’s “death drive”, his inclination towards self-destruction/self-sabotage.
I originally interpreted the apocalypse line as an extension of John’s obsession with Growing Up, since fear of arrested development is the driving theme of both Little Monsters and Failure to Launch, two of John’s posters. But I guess they’re similar, insofar as growing up/changing implies the death of your current self? Or just from the angle that both are consequences of Time. Shrug.
