You switch the view again. You're confused when you don't see a laboratory at all, then realize that you're looking at the remains of the lab you were shrunk in! This must be all that's left of it after the place crumbled away during your confrontation with SaDOS. Aside from the door, all you can see is the strange vast VOID that you keep catching glimpses of through holes in the various laboratories. You're not really sure how the door and ONE WAY MIRROR are still suspended in space, but you guess it's not any weirder than the idea of a bunch of isolated rooms floating in nothingness, connected to one another through a nonsensical and ever-shifting web of holes, tunnels, crawlspaces, and hallways.
You wonder what happened to SaDOS, since there's no sign of her. Part of you hopes she's okay, and another part of you couldn't care less what became of that Pal-throwing, needle-wielding, mouse-murdering jerk.
