What do you think happened to Aranea after she suffered a just death after game over?

Good question! She doesn’t quite return to Meenah and Vriska’s side, which means she is either too embarrassed after that fiasco to show her face around them again, or that she dies for good on the Session somehow.

There should be a distinction made here, that the Dream Bubbles are not the norm when it comes to Souls and Death in the Homestuck Universe, as we see with Aradia being a ghost on Alternia, and being able to call the spirits of the recently deceased. The Bubbles were made by the Horrorterrors, by Feferi’s Request, so it seems to imply the Horrorterrors sort of yank the Souls of those who died into the Bubbles. They appear in the Furthest Ring because of the influence the Horrorterrors have over the place.

Aranea’s ‘resurrection’ is extremely weird, because she doesn’t seem to gain a body, rather, her Soul seems to become a physical body. When she puts on the ring, her eyes fill up again, and when Condy snaps her neck, they fade again. Her Soul doesn’t exit her body or get pulled anywhere- She is the Soul, and she is cast down into the depths of the blazing wreckage left by the planets of the Session.

I am not sure of what happens to her after Game Over, but given the context given, it’s arguable that she faces whatever Afterlife there actually is in the Homestuck Universe. The Horrorterrors already pulled her Soul into the Bubbles once, she escaped, and now there’s no Soul to pull back. It’s just her, the vessel of her body is one with her Soul, and as it fades into the flames, it could fittingly be seen as her being cast down into ‘Hell’.

This is all speculation of course, there’s no explicit canonical answer, and we do see other Aranea Ghosts aside from our Aranea in the Ministrife (Not quite sure about Collide), so who’s to say she’s not just. Wandering another area of the Bubbles afterwards?

Whichever the case, I don’t think anyone would argue it’s a well deserved death.
