[No sooner had the last word left Colress's lips that the feed cuts off without so much as a word of confirmation from the anisotropic being. He's at the human's work station less than a minute later, having left the library immediately after terminating their correspondence.]

Colress. [He greets him with his name and a fond smile to announce his arrival, quickly closing the space between himself and the man's desk to stand in front of it.]

I would like to know what you have discovered.

[The anisotropic being remains silent as he watches Colress begin his demonstration, red eyes quickly darting from his hands, to the Pokeballs, to the device in rapid succession before lingering there as one of his hands appears from thin air to take it and examine it more closely. He turns it this way and that (as well as in directions that are only possible because of the seemingly-disembodied nature of his arm) as Colress continues to speak, and returns it when the human finishes his introduction to allow him his demonstration.]

I consent. I want to see it.

[Yaha-kui zaShunina nods. Though what Colress has managed to glean from Kado is remarkable, the ability to move an object "sideways" through a fourth spacial dimension is the least of its capabilities--and the easiest for three-dimensional entities to comprehend.]

Mankind was never actively aware of it. The "parallel universe theory" is the closest humanity has come to conceiving of it, but that phrase is misleading. These cross-sections are not other universes, but simply a different direction within the same universe that you are ill-equipped to perceive. You exist within a Flatland, unaware of what exists to either side of you.

[And yet there's no judgment in his tone, no derision or patronization. It is simply a fact the same as water is wet.]

Yet despite being unable to perceive it, you have devised a way to access this imperceptible direction and move objects through it. This "ignorance", as you say, is not invariable.

It is probable. [With only Colress's testimony, he can't be sure, and nothing is ever 100%, besides. The alternative would mean connecting cocoons, and that is entirely impossible for anyone who isn't anisotropic (and still has its own complications even then)... not to mention would result in the total obliteration of both cocoons. Crossing back and forth across a fourth spacial dimension is the most likely theory.

One of his detached hands retrieves a small stack of papers from nearby and sets it neatly upon the human's desk, taking the top sheet in hand.]

This is a model. To a two-dimensional entity living on the plane of a single sheet of paper, that page is its entire world. It can only move forward, backward, left, or right. [His fingertip draws the directions over the surface of the page as he speaks, then he slots the paper into the middle of the stack.] However, above and below it exist additional sheets of which it is entirely ignorant, as it lacks a concept of up or down. These sheets also possess their own two-dimensional entities with equal ignorance of the others.

[And then he touches the top of the stack, and his fingers phase through it without damaging any of the pages. Almost like it's "clipping" through the ream and penetrating down to the table beneath.]

Each page is a cross-section. They would be able to see my fingers as five separate objects, though these five objects would appear slightly different to each page. Humans are the same way. You can only see what is on your page, though this is but a fragment, and the rest of you extends to all the other pages, with gradual differences across them to form the whole.

[When his hand withdraws from the stack, the pages remain entirely undamaged. This, too, is a trick of dimensions--circumventing the three-dimensional "boundaries" of an object to pass through it.]

They are not alternate at all, but rather aspects. Extensions. Pieces of a singular existence. I am happy you understand.
