Sometimes, after ending up adrift in the multiverse, one has no clear way to return to, or even find, one's own universe. It happens to the best of us. In fact, it happens to all of us sooner or later.
Upon finding herself in that very situation, Sunset Shimmer is interviewed by an inhabitant of the universe she landed in. She's been told that, if she just answers a series of questions, her hosts will be able to locate her home timeline, and return her to the human realm within it.
She has serious doubts, but she doesn't actually have a more promising approach to solving the problem.
