the realisation that a black hole’s gravity is the same force that keeps characters ‘stuck’ in their 'homes’ recontextualises a lot.
trapping Lord English in a black hole is poetic justice, so in retrospect it’s obvious that the narrative forces behind his punishment would be the same as those behind the punishment he gives out. but the Rapture - the inevitable gathering of characters at a black hole, a tradition dating all the way back to Problem Sleuth - should also be thought of as cosmically analogous to the synonymously-named Reckoning: so it only makes sense that when a character is sucked into a black hole, it’s analogous to being returned to the hole they were born from, just as the Reckoning sends the characters to the places of their birth (and just like how cherubs return to the black holes they were literally born from to reproduce, generation after generation).
consider the sprites, being drawn to the Plot Point the same way they seem to be drawn to the Battlefield once the game of Sburb is over - remembering that the rules of Sburb dictate a sprite cannot leave the Hero’s home (until set free via pendant), we can now see that sprites are at all times subject to the whims of the gravitational pull of the childhood home.
and now that Beyond Canon’s forces all convene once more at the singularity of a black hole, setting the scene for yet another Rapture, it becomes especially clear that this meteor they’re all fighting over so intently is in fact the same meteor where the trolls were ectobiologically born. Vriska is tugged at not only by the gravity of her old toxic cycles of behaviour, the gravity of her oppressive childhood home, but by the gravity of the very literal rock that gave birth to her. the more layers we peel away, the more and more literally the Plot Point seems to be a cocoon for Vriska to be reborn from, if only she can escape that gravitational pull of the past.
remember, too, that like a cherub returning to the black hole of its birth, this meteor was once where Kanaya wished to seed the next generation of the troll race - just one small additional nuance to the fact that she must now defend it with her life from the encroaching forces of Jane’s regime.
and even Kanaya’s own Space symbol seems to take on new significance in this light. etymologically speaking, the starry arms of a 'galaxy’ are mother’s milk, befitting the aspect of creation; but the black hole that pulls the spiral arms together, too, is now the comfort of the womb. so it should be emphasised for a second time that Beyond Canon’s “constellatory quartet” - three Heroes of Space and one of Void - are convening now at their own black hole, surrounded by the spiral arms of a galaxy, pulled in by the immense gravitational influence of a monolithic entity simply called Home.
