Is it possible, in the final analysis, for one human being to achieve perfect understanding of another? We can invest enormous time and energy in serious efforts to know another person, but in the end, how close can we come to that person’s essence? We convince ourselves that we know the other person well, but do we really know anything important about anyone?
welcome to my au where jasper is an alien who arrives on earth for a recon mission and winds up at human peridots backdoor. peridot takes responsibility and immediately regrets it. jasper agrees to shapeshift into a more inconspicuous form BUT SHE WILL NOT MAKE HERSELF SMALLER! WHAT KIND OF IMPRESSION DO YOU THINK THAT WOULD GIVE!?
Imagine that, after the barrier is destroyed, Mt. Ebott/The Underground becomes a tourist trap. Humans come from all over the world to see the hidden monster kingdom, and the handful of monsters who decided to keep living there get rich by leading walking tours throughout various areas.
Imagine the River Person delighted with how many people want to explore The Underground by boat, refusing payment for their services but occasionally accepting food. Imagine the River Person and their human passengers, especially the children, singing together as they glide along the river.
Imagine that some monsters, in their haste to reach the surface, left important possessions behind. They wind up having to take the walking tours because it’s the only way they’re able to reach their old houses and retrieve their things. Some of them take the tours for fun, to see if the tour guide will talk about them when they reach their old houses, or to help the tour guide with additional information about the area. (Papyrus particularly loves doing this, much to the tour guides’ discomfort.)
Imagine Flowey occasionally trying to corrupt one of the visitors, or even trying to escape to the surface, but The Underground is always so packed with tourists that they can’t get anyone alone and always wind up surrounded by excited humans blinding it with their camera flashes. (“A talking flower, how cool! I didn’t know there were monsters like this! Honey, get a picture of me with it!”) Imagine Flowey forced to retreat to the deepest part of The Ruins where no one goes, muttering to itself and cursing Frisk.
Fake realities will create fake humans. Or, fake humans will generate fake realities and then sell them to other humans, turning them, eventually, into forgeries of themselves. So we wind up with fake humans inventing fake realities and then peddling them to other fake humans.
