I meannnnnn Vriska in the new universe is able to go up the Echeladder in Beyond Canon despite the Shurb game not even being launched yet and idk hmmm I think Beyond Canon explores how Sburb affects greater Paradox Space so I would think so?? But I can't say for sure. Rose never played the rain, but might end up doing so before HSBC ends in a sort of weird roundabout way.
