When Vriska mentions eventually needing to throw the chained-up fridge with Gamzee into earth's ocean to complete a loop (she mentions this at some point while they're first all shown on the Lilypad Platform where the door into the new universe eventually appears, I believe), do we know what loop she is referring to? Does it even matter since that fridge, I think, got sucked up into the Jack English Blackhole made by his decapitated head?

Gamzee needs to get to Earth-C somehow to raise Caliborn and Calliope, otherwise the Timeline cannot be the Alpha. Vriska, in that moment, was pretty much the Fandom- Since up until the Black Hole, the theories about Gamzee getting to Earth-C were just. Hopping on the meteor, crashing into the Earth, and skipping ahead with Aradia’s Time Tables. A Black Hole straight there is a much better gateway though.
